NYC Residential Architect for Wellness-Focused Homes

Thoughtful architecture for custom homes, townhouses, and substantial residential renovations.

Tong Dong Architects is a Queens-based residential architecture studio designing homes around light, air, comfort, building performance, and the way families actually live.

We work with homeowners across New York City, Long Island, and select areas of Westchester on custom homes, townhouse renovations, whole-home renovations, apartments, co-ops, and condos.

Our approach brings architecture, wellness, and building science together from the beginning—so the decisions that are hardest to change later are considered before construction begins.

Architecture for Homes That Work Better and Feel Better

A beautiful home should also work well.

It should bring in natural light where you need it. Stay comfortable through changing seasons. Manage air and moisture intelligently. Give your family room to move, gather, work, rest, and grow.

At Tong Dong Architects, we look at the home as an interconnected system.

Layout affects daylight. Windows affect comfort. Insulation affects mechanical systems. Materials affect indoor air. Storage affects how a room functions every day.

Considering these relationships early helps create a home that feels calm, intuitive, durable, and distinctly yours.

The Decisions That Matter Most Happen Early

Some design decisions 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, and the building envelope.

Those decisions deserve attention before construction begins.

That idea is the foundation of Build Without Regrets, our planning framework for homeowners preparing to renovate or build.

It helps you understand which decisions matter most, how they affect one another, and where early thinking can prevent expensive compromises later.

Led by Queenie Tong, RA, NCARB

Tong Dong Architects was founded in Queens, New York, by architect Queenie Tong after more than 18 years of architectural experience, including work at SOM, OMA, Gensler, and residential architecture practices.

TDA brings that experience to residential architecture at a more personal scale—combining thoughtful design, building performance, and the realities of everyday family life.

For us, wellness is not an amenity added at the end of a project.

It is part of the architecture.

A Better Home Starts With Better Decisions

The most important decisions in a residential project often happen long before construction begins.

We help homeowners understand the relationships between space, light, building systems, materials, approvals, budget, and long-term performance so the project can develop as one coordinated whole.

Whether you are planning a custom home, a townhouse transformation, or a substantial renovation, the goal is the same:

to make the important decisions deliberately—before they become difficult or expensive to change.

Co-op Renovation Approval in NYC: How to Get Your Board's Yes (and Survive the Alteration Agreement)

It is understanding the sequence. You may be wondering: Do I need board approval before filing with the Department of Buildings? What exactly is the alteration agreement?

Embracing Eco-Modern Architecture: A Path to Healthier Living Spaces
