Residential Architecture in Westchester County
Custom homes and renovations designed around how your family lives, across Westchester County, from new construction and additions to whole-house renovations that open up light, space, and connection to the outdoors.
Residential work in Westchester is shaped by the land and the lifestyle: wooded lots and sloping sites, towns with their own zoning and wetlands rules, and families who want a home that works for both daily life and entertaining. We design and manage single-family homes across the county, from new builds to major renovations, so the result fits how you live and the way your property and town allow you to build.

Key Considerations for Home Construction in Westchester
What the property will allow comes before style
Setbacks, lot coverage, FAR, wetlands, steep slopes, rock, mature trees, drainage, and flood or coastal triggers can shape the project before design begins. We identify those constraints early so the first design direction is grounded in what the property and town are likely to allow.
Older houses need careful surgery
Opening up a dated suburban layout means working with existing structure, rooflines, foundations, plumbing, heating, and electrical systems. We plan additions and renovations around what the house can reasonably support, so the finished work feels intentional rather than patched together.
Indoor-outdoor living depends on the site
Connecting a home to its yard, terrace, pool, or view takes more than larger windows. It means coordinating grading, drainage, circulation, light, privacy, and seasonal use so the inside and outside work together.
Approvals have to be mapped early
Most homeowners have not managed a custom home, addition, or whole-house renovation before. We map the path through engineers, surveys, town filings, boards, contractor pricing, and construction so you understand the sequence before the project is in motion.
How your Westchester project unfolds
Every project moves through the same four phases. In Westchester, the work that needs the most local knowledge is the town approvals, which we manage directly so you do not have to.
01
Discovery & Feasibility
We start with how your family lives and what your site allows, reviewing zoning, setbacks, lot coverage, wetlands, coastal or floodplain triggers, building code, and likely approval steps before the design direction hardens.
02
Schematic Design
We develop floor plans, exterior concepts, and 3D views that show how the home will function, how it will sit on the land, and how new work connects to the existing house and yard.
03
Design Development, Construction Documents & Permitting
We prepare detailed drawings and permit sets, coordinate consultants, and work with the town building department, planning or zoning board, architectural review board, wetlands review, or other local review bodies when required. where required.
04
Construction Administration
We stay involved during construction, coordinating the design with the general contractor and consultants so field questions are resolved and the finished home follows the approved design intent.

Questions we often get about Westchester projects
Which Westchester towns do you work in?
We design homes throughout the county, from the lower Westchester suburbs like Scarsdale and Larchmont to the northern towns such as Bedford and Chappaqua, as well as the river towns.
Do you handle town zoning and planning board approvals?
Yes. We prepare the required drawings and coordinate directly with the town building department, planning and zoning boards, and wetlands review when a site calls for it. Our leadership holds zoning board and planning board positions, so we understand the process and how to get quick approvals, from the inside out.
Do you design new homes as well as renovations?
Both. We design new custom homes and major whole-house renovations and additions, and we manage each from design through construction completion.
What is included in your interior design services?
Interior design covers FF&E, space planning, and integration within the architecture, so the home is not only well built but fully realized. We source and manage furniture, wall coverings, decorative lighting, accessories, and draperies through installation.
Can you help us understand what we are allowed to build?
Yes. Early feasibility is a key part of our process. We review zoning, setbacks, lot coverage, floor area, wetlands, floodplain or coastal triggers, easements, and other site conditions that may affect the design before the project moves too far in the wrong direction.
How early should we call an architect?
The best time is before you have committed to a scope, budget, contractor price, or property purchase. A short feasibility review can identify zoning, site, and existing-condition issues before they become redesigns or delays
