NHA Standard Housing Models Manual
This first edition of the NHA Standard Housing Models Manual serves the following
purposes:
An official document:
The manual serves as an official document to which NHA officials and
stakeholders can refer to for information about agency-approved standard
housing models. As such, the existence of the manual indicates that other
housing models, those which are not included in the manual, are not official
and cannot be implemented for housing projects being undertaken by the
NHA.
A planning tool in the housing production and delivery process:
The manual compiles information about all standard housing models that are
relevant in the planning stage of a housing project so that planners and
stakeholders can easily review and compare available options. Furthermore, the
manual communicates the design goals and strategies behind the housing
models, clarifying why models are designed the way they are. In effect, the
manual serves as a guide for selecting housing models that are well-suited to
project requirements.
The complete working drawings of the housing models herein included are
available upon request from the HTDO.

FOREWORD
Through the years, housing designs of the National Housing Authority
(NHA) have evolved brought about by the many changes and challenges and
effects of climate change. The improvements were made to provide better and
quality housing and to meet the demands of the end users especially the lowest
30% of the income population. Conceptualization, consultation and
development process were undertaken to come up with standard housing
designs.
It is with great pleasure that the first edition of the Design Manual has
been completed and realized during this term through the efforts exerted by the
team from the Housing Technology Development Office (HTDO). This serves as
another milestone of NHA.
The purpose of this Design Manual is to provide a reference to designers
and builders, students and professionals, and to all our partners in the housing
industry.
It covers the various NHA housing models with design parameters and
the typical construction details illustrated and simplified for better
understanding. Best practices in the implementation of the housing projects are
also considered.
7
I am confident that through our
concerted efforts, we will be able to achieve our
goals in providing safe, affordable, resilient and
decent housing especially to the marginalized
sector of our society.
It is the desire of NHA that this Manual
serve its purpose well. If there is any detail or
information which has been inadvertently
overlooked, necessary corrections shall be
made at best possible opportunity.

MESSAGE
I congratulate the NHA’s Housing Technology Development Office
(HTDO) under the leadership of its Department Manager, Ar. Ma. Benita O.
Regala, for the crafting and release of this NHA Design Manual.
The Manual will definitely be a useful tool among all NHA technical
practitioners to enable them to plan and develop sustainable, disaster-resilient
housing for our homeless and underprivileged citizens who are in need of much-
needed shelter and other housing-related components. This Manual is also
significant, since this could also be a source of information among other external
stakeholders, including the public in general, of the types of housing being
implemented by NHA under its various programs.
It is my sincere hope that this will be a continuing effort of NHA to strive
excellence and pursue innovation housing technologies towards a more
responsive and affordable housing for the poor.
9
Again, congratulations and thank you to
the management and staff of HTDO, and to all who
contributed for making this Manual a workable
guide in NHA and practitioners in the field of
housing.

MESSAGE FROM THE AUTHOR
A design manual had been conceptualized way back in 2010 when the
First Design Conference on Gender Mainstreaming on Housing Design was held
on February 16-17,2010. Participants came from all sectors in the industry and
was spearheaded by the Housing Technology Development Office (HTDO),
under the sponsorship of the Gender and Development Committee headed at
the time by Ms. Lorna M. Seraspe. The objective of the conference was to
determine gender sensitive parameters for housing design. Three entry points
were considered, such as the following: Access to Housing, Participation and
Consultation, and Housing Design, the latter being the focus of said conference.
Today six years later, the proposed manual had evolved into a disaster
resilient design manual for the socialized sector in view of the 2013 Typhoon
Yolanda, the strongest typhoon ever to hit land which happened in the Visayan
Region. A Technical Working Group was organized by the NHA through the
HTDO’s initiative and again multi-stakeholder design consultations were held in
November and December, 2013. At the end of the conference, parameters for
disaster resilience for housing was determined and agreed on.
11
This design manual brings home the point that
housing design and construction details matter to
achieve resiliency. It is hoped that with the publication
of this document, both our technical and non-technical
employees will be able to better understand the
principles of good construction. Other end-users and the
public in general is also envisioned to benefit from these
design guidelines.
Let me thank my HTDO Team for this valuable
work that has been done as our legacy to future
generations of planners and designers, and to the
housing sector as well. Cheers and Mabuhay!

NATIONAL HOUSING AUTHORITY
VISION
By 2019, NHA would have provided 50% of the housing needs for
homeless low-income families (based on the 2011 census) primarily those living in
waterways, danger areas, and government infrastructure project sites in Metro
Manila and all regions nationwide.
MISSION
We provide decent, adequate, and affordable housing to low-income
families, ensure the provision of community facilities, utilities, and access to social
services and economic opportunities.

NHA MANDATE
The National Housing Authority (NHA) is the sole national agency
mandated to engage in housing production for low income families. It traces its
roots to the People's Homesite Corporation (PHC), the first government housing
agency established on 14 October 1938 and to the National Housing
Commission (NHC) which was created seven years later, on 17 September 1945.
These two agencies, the PHC and the NHC, were eventually merged on 4
October 1947 into the People's Homesite and Housing Corporation (PHHC).
In the years that followed, six(6) more housing agencies were created to
respond to separate and distinct shelter requirements, namely: the Presidential
Assistant on Housing and Resettlement Agency (PAHRA); the Tondo Foreshore
Development Authority (TFDA); the Central Institute for the Training and
Relocation of Urban Squatters (CITRUS); the Presidential Committee for Housing
and Urban Resettlement (PRECHUR); the Sapang Palay Development
Committee (SPDC); the Inter-Agency task Force to Undertake the Relocation of
Families in Barrio Nabacaan, Villanueva, Misamis Oriental. Eventually, on 15
October 1975, the National Housing Authority was organized as a government-
owned and-controlled corporation, by virtue of Presidential Decree No. 757
dated 31 July 1975. All other housing agencies were abolished by the said
decree. The NHA took over and integrated the functions of the abolished
agencies - the PHHC and the six (6) other housing agencies. The creation of the
NHA is the second attempt of the government to integrate all housing efforts
under a single agency, twenty-eight years after the merger under the PHHC.
16
Three years later, the Ministry of Human Settlements (MHS) was created in
1978. The Ministry adopted the holistic approach to housing. The NHA was
placed as an attached agency to the MHS.
On 26 March 1986, Executive Order No. 10 was issued placing the NHA
as well as the other agencies attached to the abolished MHS, under the
administrative supervision of the office of the President. Subsequently, Executive
Order No. 90 was issued on 17 December 1986, rationalizing the housing
structure in the government along lines of specialization and concentration.
EO 90 identified the key housing agencies to implement the National
Shelter Program and defined their respective mandates. The NHA was
mandated to be the sole government agency to engage in housing
production. Under the said Executive Order, NHA was placed under the policy
and program supervision of the Housing and Urban Development Coordinating
Council (HUDCC), the umbrella agency for shelter charged with the main
function of coordinating the activities of various government housing agencies
engaged in production, finance and regulation.
Executive Order No. 20 on 28 May 2001 reaffirmed mass housing as a
centerpiece program in the poverty alleviation efforts of government. Said EO
likewise reaffirmed HUDCC's administrative supervision over the housing
agencies including the NHA.
17
BACKGROUND OF THE MANUAL
In 1998, NHA housing design prototypes were compiled as a Manual. This
is the result of a standardization effort to ensure that housing units produced by
the Agency were of good quality. Existing housing structures at the time were
reviewed and analyzed. Cost-efficiency, code compliance, functionality, and
cultural appropriateness were examined. Through the study, specific design and
construction strategies for adaptability and cost-effectiveness were formulated.
Having these strategies in hand, housing prototypes were designed, the plans
and details of which comprised the first edition of the manual.
Since the first manual, product requirements have changed significantly
so, such that the plans of the prototypes in the said manual have ceased to be
applicable to NHA housing projects. As new requirements emerged, some
aspects of the prototypes were adjusted to suit. In other cases, new building
prototypes were developed altogether. These new prototypes, or models, being
the applicable and relevant solutions at present, comprise this first edition of the
manual.

Memorandum Circular No. 2016 – 098
SUBJECT: NHA Standard Housing Models Design Manual
Consistent with the National Housing Authority’s continuing effort in “Providing
adequate, safe, and affordable housing and ensure the availability of basic services,
community facilities and access to social and economic opportunities to homeless
low-income families”, as stated in its commitment to national development, the
attached NHA Standard Housing Models Design Manual (Design Manual, for brevity)
is hereby adopted.
1.0 BACKGROUND AND PURPOSE
1.1 Among the mandated functions of the Housing Technology Development Office
(HTDO) is to “undertake continuous improvement of the Authority’s project
development process for infrastructure projects to ensure responsiveness to
environmental, institution and social changes” primarily through the
“development of design standards of housing and building units”1.
1.2 In 1998, the Task Force on Housing and Project Development (predecessor of
HTDO), compiled in a manual the NHA housing prototypes with detailed design
and quantity take-offs. The compilation was a result of the standardization effort to
ensure good quality in the housing units being produced by the NHA through
designs aimed to achieve adaptability and cost-effectiveness.
1.3 Typhoon Yolanda in late 2013 has prompted the review and revision of NHA
planning standards brought about by the need for more suitable sites and resilient
houses as a response to the so-called “new normal” in climate, which constitutes
stronger typhoons, severe droughts, and more and heavier rains resulting in
destructive floods and landslides.
1.4 With such new requirements, more particularly the need for disaster resilient
homes for the sector most vulnerable to the effects of disasters, there was a need
to also evolve the designs of housing models.
1As stated in NHA Office Order No. 5131 dated 08 March 2002 which reconstituted and redefined functions of
then Task Force on Housing and Project Development into what is now the Technical Services Group (TSG) with two sub-offices – HTDO and POSSO
19
1.5 Spearheaded by the HTDO, this was carried out through processes of multi-
sectoral consultation and design processes adopting upgraded structural
parameters as approved by the Department of Public Works and Highways
(DPWH) while still considering affordability.
1.6 Moreover, details specifying housing design standards from a number of NHA
memorandum circulars were incorporated into the models. The most recent
provisions are adopted in cases where specific details vary across different
programs and projects.
1.7 Hence, this edition of the NHA Design Manual is issued incorporating the new
features and presenting the new models of single story housing units to be
implemented in our resettlement projects.
1.8 The purpose of the Design Manual is to serve as reference on standard
construction details and quantity take-offs of single story house models for use by
various stakeholders, but more so for planners and implementers of NHA
resettlement projects.
2.0 SCOPE AND COVERAGE
2.1 The standards and details contained in the Design Manual shall cover all current
and future resettlement projects that will adopt single story house typologies
either without loft, loftable, or lofted.
2.2 The Design Manual consists of the legal bases, design process, house construction
details, and the description, drawings and quantity take-offs of each of these
housing models:
2.2.1 21 Square Meter Duplex
2.2.2 22 Square Meter Rowhouse (Loftable and With Loft)
2.2.3 26 Square Meter Rowhouse
2.2.4 28.4 Square Meter Rowhouse
2.2.5 33 Square Meter Rowhouse with Loft and Store Space
2.2.6 22 Square Meter Single Detached

DESIGN PHILOSOPHY
Improvement of the design of the NHA standard housing models was
guided by one overarching design philosophy, that is, Sustainable Development
(SD). As such, the design goals, objectives, and indicators were derived from this
philosophy.
SD is the national agenda for development, which was adapted in
support of the same international agenda . As the UN states,
Thus, given that housing makes for a large part of national
development, SD was identified to dictate the course of this housing design
improvement effort.
Throughout the design process, SD was observed with the understanding
that it is “development that meets the needs of the present without
compromising the ability of future generations to meet their own needs (3)”
28
DESIGN GOALS
In setting design goals, SD was considered in its three aspects — the
social, the environmental, and the economic (2). As much as possible,
“integrated” design goals were set, that is, the accomplishment of a goal should
in most cases support the accomplishment of another goal.
Social Sustainability
A housing development is socially sustainable when it empowers, includes, and
continuously provides for the needs of people, affording them a healthy and
fulfilling life.
1 Historically, a barrier-free unit (i.e., a house that fully complies with all the requirements under BP 344) costs more
than a non-barrier-free unit. Thus, designing for “accessibility” as described herein, was limited to items that would
pose insignificant increases in costs. Focus was given to adequate space allowances so that, in case the need
arises, the house could be easily converted into a barrier-free facility.
29
30
Environmental Sustainability
A housing development is environmentally sustainable when it uses
natural resources to sustain human life without destroying or depleting these
resources permanently.
31
Economic Sustainability
A housing development is economically sustainable when it is cost-
efficient and self-sustaining.
34
DESIGN OBJECTIVES AND INDICATORS Guided by the different ways in which the purpose of a house may be
considered, design objectives were derived. The design objectives and
Indicators were defined with the following assumptions:
35
The indicators describe provisions that increase probable success in
achieving the design objectives. These indicators were not intended to serve as
an exhaustive compilation of ALL design requirements for dwellings. All
applicable code requirements, covered by the indicators herein or otherwise,
were still observed.
In the process of designing this framework, some design objectives were
found to contribute to the achievement of some design goals while possibly
hampering the achievement of other design goals. For example, achievement
of the design objective, “materials used for the structure are inherently resistant
to the effects of earthquakes and typhoons,” may result to disaster-resilience
and low maintenance, but may not result to low initial cost. Thus, in such cases,
the NHA design team had to consider satisfying design goals in varying degrees;
that is, although a strategy may not completely satisfy a certain design goal, it
must neither completely prevent that design goal from being achieved.
DESIGN CHECKLIST This design process was enabled and applied through a design checklist.
The design checklist was created to aid NHA designers in ensuring that each
and every design objective was considered and reflected in the design of
housing models.
36
37
The Design Challenge
Shelter design greatly influences the habits and lifestyle patterns of
people and the way that they relate to the built environment and nature. The
design challenge confronting planners and builders today is how to address
climate change adaptation and gender issues, and how to find ways to
transform their inputs into concrete and viable housing solutions. Another
challenge is the problem of providing livable and sustainable housing vis-a-vis
construction costs and affordability. Production and construction costs have
been constantly going up while family incomes have not proportionately
increased over the years, making it more difficult to provide quality affordable
shelter for the low-income sector. This design manual illustrates how NHA
addresses such challenges given the technical and financial issues confronting
housing construction for the low income.
Design Standards
Batas Pambansa 220 ( BP 220) a law that was passed in 1982,
authorizing the Housing and Land Use Regulatory Board to establish and
promulgate two levels of standards and technical requirements for the
development of economic and socialized housing projects in urban and rural
areas, provided a framework for making available adequate housing for
average and low-income earners.
In 2008, revisions were made to the Implementing Rules and Regulations
(IRR) of BP 220. Such changes include the provision of the minimum lot size of 28
square meters, and the minimum floor area for a socialized housing unit at 18
square meters. Land use ratio for buildable and non-buildable areas is set at
70%-30% ratio.
NHA for its part, improved its own design standards in terms of lot and
housing unit sizes, as well as in the applicable land uses. The most recently
approved guideline for site development is now set at 60% saleable (residential,
commercial and industrial, institutional) and 40% non-saleable (open space
community facilities, easements, road networks and footpaths).
38
After Typhoon Yolanda, it has become more evident that typhoon
patterns and flooding levels have become unpredictable. Hence, the need for
disaster resilient parameters. The NHA conducted its own design conference to
arrive at these standards to address resiliency for housing. These parameters are
defined in page 134 of this manual.
In coming up with the housing models, the following principles were
considered :
1. Social and cultural: Behavioral patterns of people must be carefully
studied based on previous experience and historical data. Design should
consider acceptability and cultural adaptability of any housing
development to the specific target market.
2. Physical Aspect :
a. The exterior design of the building can never be disassociated from its
interiors. The roof, columns and beams, walls and floors, window and
door openings provide the enclosure to the structure The conscious
planning of each of the exterior parts directly affect the conditions
inside the house such as areas for sleeping, living, dining, kitchen,
laundry and toilet facilities. Further, natural light and ventilation should
be adequately provided to save on energy costs.
b. Furniture layout inside the buildings and partition walls should be
planned in same manner with thought on the layout of fixtures such as
cabinets, beds and even storage for cleaning tools and equipment.
c. Lighting and convenience outlets must also be strategically located for
easy access within the housing units, but with consideration to the
safety of the children.
d. Careful placement of spaces in relation to the solar and wind
orientation and their dimensions all relate to the indoor quality of the
house.
39
3. Maintenance and Sustainability : Project design and development must
consider the aspect of maintenance to sustain the architectural and
structural integrity of the buildings and the environmental quality of
neighborhoods.
4. The planning, architectural lay-outing and utilization of spaces within and
surrounding such buildings or structures must be well coordinated with
the design of the utilities inside and outside of the structures. As an
example, the location of electrical posts and septic tanks was
considered in the setback requirements.
5. Budget consideration : The sector being served by the NHA belongs to
the lowest 30% of the income population, so that affordability levels is of
utmost importance. The housing package which include the house and
lot models must meet the required social, cultural and physical aspects
within the financial scheme for each of the programs for
implementation.
ROWHOUSE
The one-story rowhouse model has been the most typical of all the
models constructed by the NHA in most of its resettlement projects all over the
country. At the onset of the Northrail Relocation and Resettlement Program, this
model was offered to project beneficiaries under the Community Association
Initiated Approach or CAIAP. The model is a 20 square meter shell unit on a 32-
40 square meter lot, with provision for one toilet and bath and one kitchen
counter. Beneficiaries were left to improve on their unit and on the provision of
partition walls and architectural finishes. To better serve the needs of
households, and based on a wish list submitted by community representatives
(FGD Gender and Development Technical Working Group from 2010 to 2012),
the following house models were designed by the NHA through the HTDO.

uncommon for sawali to also be used as a design element in
higher class leisure centers and other structures to portray a
rustic cultural architectural style.

most important of which are to create a buffer area for rising
waters during floods, and to prevent pests such as rats from
getting up to the living area.[2] This section of the house is often
used for storage, and sometimes for raising farm animals,[4] and
thus may or may not be fenced off.

Housing Technology Development Office Brief History and Function
The Housing Technology Development Office (HTDO) is one of the two sub-
offices under Technical Services Group (TSG) pursuant to NHA Office Order No. 5131
dated 08 March 2002 (copy attached as Annex 1) which was a reconstitution and
redefinition of functions of the Task Force on Housing Technology and Project
Development created under Office Order No. 9738 of December 1993.
The functions as stated in said Office Order No. 5131, and which are still being
undertaken by HTDO, are:
1. Undertake continuous improvement of the Authority’s project development process for
infrastructure projects to ensure responsiveness to environmental, institution and social
changes primarily through the following:
A. Development of design standards of housing and building units
B. Development of standard site development schemes and design of utilities and
infrastructures
C. Development of alternative building and site configuration plan
2. Research and develop low cost housing technology and alternative housing materials,
including prototype design of housing units and engineering components.
3. Act as the Technical Secretariat for AITECH accreditation of housing technology
schemes.
4. Provide technical and research assistance to management and operating units in
developing housing programs and approaches.
5. Provide the technical planning and support services to operating units, during the pre
design phases.
6. Establish and manage the authority’s technical databases to include, among others,
an updateable information resource on construction materials and price indices.
The HTDO is also in charge of the development of the master plan and the
supervision of construction of new structures in the NHA Main Compound per Office
Order No. 9545 dated June 10, 2010. It coordinates with other government agencies and
other organizations on matters pertinent to housing and planning (e.g., disaster risk
reduction, climate change adaptation, green building, gender sensitivity) to enhance
the NHA’s capacity in carrying out its mandate. Moreover, HTDO aims to encourage the
use of innovative housing technologies, materials and building systems as an alternative
to the traditional housing construction system.
