Healthy Home Design Review for NYC Renovations
An independent architectural second opinion before your design becomes expensive to change.
Already working with an architect, interior designer, builder, or design team?
​
Sometimes you do not need to start over. You need another experienced set of eyes.
​
Tong Dong Architects' Healthy Home Design Review is an independent architectural review for homeowners who already have renovation or new-home plans and want to understand whether the design fully addresses the way the home will live, feel, and perform.
​
We review your existing architectural plans through the lens of healthy home design, building performance, everyday function, and long-term comfort—before major decisions are locked into construction.
​
The goal is not to redesign your project or replace your current architect.
​
It is to identify important questions, overlooked opportunities, and decisions worth reconsidering while there is still time to act on them.
​
Already Have Plans? This Is the Moment to Look Again.
By the time a residential design reaches construction, many of its most important decisions have already been made.
The floor plan determines how your family moves through the home.
​
Windows affect daylight, drafts, heat gain, privacy, and comfort.
​
Insulation and the building envelope affect temperature and moisture.
​
Ventilation affects indoor air quality.
​
Mechanical systems affect comfort, noise, energy use, and air movement.
​
Materials affect indoor air, durability, maintenance, and how the home ages.
​
These decisions are interconnected—and many become difficult or expensive to change once construction begins.
​
A Healthy Home Design Review allows you to step back and evaluate the project as a whole before those decisions become permanent.
​
What is a Healthy Home Design Review?
A Healthy Home Design Review is an architect-led review of an existing residential design.
​
You provide your current architectural drawings and information about your project, priorities, and concerns. Tong Dong Architects reviews the design independently and identifies areas that may deserve additional consideration.
The review goes beyond whether the floor plan simply “works.”
We look at how the proposed home addresses:
-
space planning and daily function
-
natural daylight
-
indoor air quality
-
ventilation
-
moisture management
-
thermal comfort
-
the building envelope
-
material choices
-
acoustic comfort
-
mechanical systems
-
storage and circulation
-
long-term flexibility
-
the relationships between building systems and design decisions
The result is a clearer understanding of what is working well, what may be missing, and which decisions deserve another conversation with your project team before construction begins.
​
Who is this Service For?
The Healthy Home Design Review is designed for homeowners who already have a project underway.
It may be a good fit if you are:
​
Working With an Architect
You like the overall direction of your project but want an independent architectural second opinion before approving the design.
​
Working With an Interior Designer
Your interiors are developing, but you want an architect to review larger questions involving layout, daylight, ventilation, comfort, building systems, or building performance.
​
Working With a Design-Build Team or Contractor
You have plans prepared by a builder, contractor, design-build company, or drafting service and want another professional perspective before construction.
​
Reviewing Plans for a Custom Home
You are preparing to build a new home and want the design reviewed through a healthy-home and building-performance lens before the plans are finalized.
​
Planning a Major Renovation
You are renovating an apartment, co-op, condo, townhouse, or house and want to identify potential design issues before contractor pricing or construction begins.
​
Feeling Unsure About Your Current Design
Something does not feel quite resolved, but you cannot identify exactly what is bothering you.
A fresh architectural review can help turn that uncertainty into specific questions and actionable decisions.
​
What We Review
Every project is different. The Healthy Home Design Review focuses on the areas most relevant to your home, project stage, and priorities.
​
1. Floor Plan, Layout + Daily Life
A good floor plan should do more than fit the required rooms.
​
We review how the design supports the way you actually live.
That may include:
-
room relationships
-
circulation
-
furniture placement
-
privacy
-
family routines
-
kitchen function
-
storage
-
entry sequences
-
work-from-home needs
-
children’s spaces
-
transitions between public and private areas
-
flexibility as your family changes
Small planning decisions can have a large effect on how a home feels every day.
​2. Natural Light + Daylight
Natural light is not simply a matter of having enough windows.
​
Window orientation, room depth, partitions, ceiling conditions, finishes, neighboring buildings, and interior openings all influence how daylight moves through a home.
​
We review opportunities to improve:
-
daylight distribution
-
darker interior spaces
-
window relationships
-
borrowed light
-
room placement
-
visual connection
-
glare
-
privacy
-
the relationship between daylight and daily activities
For deep NYC apartments and narrow townhouses, these relationships can be especially important.
​
3. Indoor Air Quality + Ventilation
A beautiful renovation can still feel stuffy, humid, odorous, or uncomfortable if air is not managed properly.
​
We review the architectural implications of:
-
fresh-air strategies
-
exhaust
-
kitchen ventilation
-
bathroom ventilation
-
filtration
-
air movement
-
mechanical system location
-
combustion appliances
-
material emissions
-
construction dust considerations
Indoor air quality is rarely solved by one product. It is the result of multiple systems working together.
​
4. Moisture + Water Management
Water is one of the most important building-performance issues in any home.
​
For townhouses and substantial residential renovations, we may review questions involving:
-
roofs
-
exterior walls
-
basements and cellars
-
bathrooms
-
kitchens
-
waterproofing
-
drainage
-
condensation risk
-
humidity
-
drying potential
-
transitions between building assemblies
The objective is not simply to keep water out.
A resilient home also needs to manage moisture and be able to dry when materials become wet.
​
5. Building Envelope + Thermal Comfort
If one room is always cold, another overheats, or the area beside a window feels uncomfortable, the issue may involve more than the thermostat.
​
We look at the relationship between:
-
windows
-
exterior walls
-
insulation
-
air leakage
-
orientation
-
solar exposure
-
shading
-
mechanical systems
-
room layout
-
surface temperatures
These elements work together to determine how comfortable a home actually feels.
​
6. Materials + Indoor Environment
Healthy material selection is more complex than choosing something labeled “natural,” “green,” or “non-toxic.”
​
We may review proposed:
-
flooring
-
cabinetry
-
millwork
-
paints
-
coatings
-
adhesives
-
sealants
-
insulation
-
countertops
-
wall finishes
-
built-in materials
We consider materials in the context of emissions, exposure, durability, maintenance, moisture, installation, and intended use.
The goal is not a perfectly “non-toxic” home.
The goal is to make informed material decisions where they matter most.
​
7. Acoustic Comfort
Noise can dramatically affect the experience of a home.
​
In New York City, that noise may come from streets, neighbors, hallways, mechanical equipment, plumbing, children, entertainment areas, or work-from-home activities.
​
We review the design for potential acoustic conflicts involving:
-
bedroom location
-
shared walls
-
floors and ceilings
-
doors
-
mechanical systems
-
plumbing
-
home offices
-
family gathering spaces
-
street-facing rooms
A calm home should work acoustically as well as visually.
​
8. Building Systems + Design Coordination
Homes work as systems.
​
Changing one part of the design can affect several others.
​
Moving a kitchen may affect exhaust and plumbing.
​
Changing windows may affect comfort and heating loads.
​
Adding insulation may change moisture behavior.
​
Opening a floor plan may affect lighting, acoustics, structure, and mechanical distribution.
​
We look for these relationships so that individual design decisions are considered as part of the larger home rather than in isolation.
​
At Tong Dong Architects, we believe the most consequential residential design decisions often happen long before construction starts.
​
Some things are easy to change later.
​
Paint can be repainted.
​
Furniture can be replaced.
​
Hardware can be changed.
​
Other decisions become embedded in the architecture:
-
floor plans
-
windows
-
structure
-
waterproofing
-
insulation
-
ventilation
-
mechanical systems
-
the building envelope
These are the decisions that deserve particular attention before construction.
Our Healthy Home Design Review applies the same thinking behind TDA's Build Without Regrets framework to your actual project.
Rather than reviewing individual products in isolation, we look at how air, moisture, envelope, daylight, comfort, materials, systems, and daily life work together.
​
How the Healthy Home Design Review Works
Step 1 — Tell Us About Your Project
You provide basic project information, your current design drawings, and the questions or concerns you would most like us to examine.
​
Depending on the project, useful documents may include:
-
floor plans
-
elevations
-
sections
-
reflected ceiling plans
-
window information
-
mechanical information
-
material selections
-
photographs
-
existing-condition drawings
-
design presentations
Not every project will have all of these documents.
​
Step 2 — Independent Architectural Review
Tong Dong Architects reviews the available drawings through the lens of architecture, healthy-home principles, building performance, and everyday use.
​
We look for both strengths and potential gaps.
​
The purpose is not to criticize your existing design team.
​
It is to bring another architectural perspective to the project while meaningful changes are still possible.
Step 3 — Identify Priorities
Not every observation has the same importance.
​
We distinguish between issues that may significantly affect long-term performance or livability and those that are simply opportunities for refinement.
​
Recommendations may be organized around priorities such as:
Address Before Moving Forward
Issues that may affect major architectural, building-performance, or coordination decisions.
Worth Discussing With Your Design Team
Opportunities that deserve further consideration before plans are finalized.
Already Working Well
Strategies within the existing design that support the project's goals and should be protected as the project develops.
​
Step 4 — Review the Findings Together
We meet to walk through the findings and discuss the reasoning behind the recommendations.
​
You can then bring the relevant questions and observations back to your architect, designer, contractor, engineer, or project team.
​
Your existing team remains responsible for developing, coordinating, documenting, and implementing the final design.​
​
A Second Opinion—Not a Second Design Team
The Healthy Home Design Review is intentionally focused.
​
TDA is not taking over your existing project.
​
We respect the work already completed by your architect, designer, contractor, and consultants.
​
Our role is to provide an independent architectural second opinion and identify areas that may benefit from further discussion before construction.
​
Unless separately commissioned, the Healthy Home Design Review does not include:
-
redesigning the entire project
-
preparing construction documents
-
DOB filing
-
code analysis or code-compliance certification
-
engineering
-
mechanical system design
-
architectural stamping
-
contractor management
-
construction administration
-
replacing your Architect of Record
-
directing your existing consultants or contractor
Recommendations are intended to help you have a more informed conversation with the professionals responsible for your project.
​
When Should You Request an Architectural Design Review?
The best time is after there is enough design to evaluate but before important decisions are difficult to change.
For many projects, that means during schematic design or design development—before construction documents, contractor pricing, purchasing, or construction are substantially complete.
A review may be particularly valuable:
-
before approving a preferred floor plan
-
before finalizing windows
-
before locking in mechanical strategies
-
before selecting major finish systems
-
before contractor pricing
-
before signing off on construction drawings
-
before ordering long-lead items
-
before demolition or construction begins
The later the review occurs, the fewer options the project may have without affecting cost or schedule.
​
NYC Renovations Require a Different Kind of Review
Residential design in New York City operates within unusual constraints.
​
Apartments, co-ops, condos, and townhouses may be affected by:
-
existing building construction
-
limited exterior exposure
-
neighboring buildings
-
building alteration agreements
-
co-op or condo requirements
-
plumbing restrictions
-
wet-over-dry rules
-
flooring and acoustic requirements
-
ventilation limitations
-
electrical capacity
-
window restrictions
-
landmark conditions
-
existing shafts and risers
-
tight mechanical spaces
-
limited construction access
A healthy-home strategy that works in a suburban new-build may not translate directly to an NYC apartment or townhouse.
TDA's review considers wellness and building-performance goals in the context of what your building can realistically support.
​

​
Why Tong Dong Architects?
Tong Dong Architects is a New York residential architecture studio led by Queenie Tong, RA, NCARB.
​
TDA approaches healthy-home design as architecture—not as a collection of wellness products or upgrades.
​
We study how:
-
layout affects daylight.
-
windows affect comfort.
-
insulation affects mechanical systems.
-
materials affect indoor air.
-
moisture affects durability.
-
storage affects everyday life.
Our approach brings together residential architecture, healthy-home principles, building science, and the realities of family life.
The objective is simple:
Create homes that work better, feel better, and continue to perform well long after construction is complete.
​
Get a Second Set of Eyes Before You Build
You have already invested significant time, thought, and money into your project.
​
Before the plans become construction, it can be valuable to ask one more question:
Are we overlooking anything that will be difficult to fix later?
​The Healthy Home Design Review provides an independent architectural perspective while there is still time to make informed decisions.

Healthy Home Design Review FAQ
What is an architectural design review?
An architectural design review is an independent evaluation of existing architectural plans. Rather than creating a design from the beginning, the reviewing architect studies the proposed design and identifies questions, potential issues, and opportunities for improvement before construction.
​
Can an architect give me a second opinion on plans prepared by another architect?
Yes. An independent architect can review existing plans and provide a second professional perspective. The original Architect of Record remains responsible for the design, documentation, approvals, and implementation of the project unless another arrangement is formally established.
​
Can you review plans prepared by my contractor or design-build company?
Yes. Depending on the level of information available, TDA can review plans prepared by an architect, interior designer, design-build company, builder, contractor, or drafting professional and identify architectural questions worth discussing with your project team.
​
Will you redesign my floor plan?
The Healthy Home Design Review is primarily an evaluation and advisory service rather than a full redesign. If the review identifies a significant planning issue, we may explain potential directions to explore, but preparation of revised architectural design drawings would require a separate scope of services.
​
What does a healthy home architect look for when reviewing plans?
A healthy home design review may consider floor-plan function, natural light, indoor air quality, ventilation, moisture, the building envelope, thermal comfort, acoustic comfort, material choices, mechanical systems, storage, circulation, and how these decisions interact.
​
When should I have my renovation plans reviewed?
Ideally, the review should happen after a design has developed enough to evaluate but before construction documents, contractor pricing, purchasing, or construction make changes costly. Schematic design and design development are often good stages for an independent architectural review.
​
Can you review an NYC apartment or co-op renovation?
Yes. NYC apartment, co-op, and condo projects often have building-specific restrictions involving plumbing, ventilation, flooring, electrical systems, windows, acoustics, and alteration agreements. These constraints need to be considered when evaluating healthy-home strategies.
​
Can you review a NYC townhouse renovation?
Yes. Townhouse design reviews may consider layout, daylight, building-envelope performance, insulation, windows, moisture, cellar conditions, ventilation, mechanical systems, acoustics, materials, and the relationships between existing construction and the proposed renovation.
​
Can you review plans for a new custom home?
Yes. A Healthy Home Design Review can also be used for a new residential design when you already have an architect, designer, builder, or plan set and want an independent review focused on healthy-home design and building performance.
​
Does the design review replace my architect?
No. The service is intended to complement—not replace—your existing architect or design team. Your Architect of Record and project consultants remain responsible for design development, technical documentation, code compliance, approvals, coordination, and construction.
​
Is this the same as a home inspection?
No. A home inspection evaluates the physical condition of an existing property. A Healthy Home Design Review evaluates a proposed architectural design before it is built or substantially renovated.
​
Is this the same as the TDA Healthy Home Assessment?
No. The Healthy Home Assessment helps homeowners identify healthy-home topics that may deserve attention.
The Healthy Home Design Review evaluates your actual architectural plans and provides project-specific professional feedback.
​
What if the review identifies a larger architectural problem?
We will explain why the issue deserves attention and recommend discussing it with the appropriate member of your project team. If additional architectural services from TDA would be useful and there is no conflict with your existing professional relationships, those services can be discussed separately.
