A Westchester Tudor does not need to be modernized. It needs to be made to work, without losing the reason you bought it.
Interior Design in Westchester County
Westchester is where New York money went to build houses. Scarsdale is the clearest expression of it — Fox Meadow, Heathcote, Murray Hill, Greenacres, Quaker Ridge — stucco-and-timber Tudors, slate roofs, leaded casements, and center-hall colonials on lots that were laid out when land was cheap and ambition was not. Bronxville is the opposite scale and the same standard: one square mile of village, Lawrence Park's shingle and stone houses on the hill, and a ring of prewar co-op buildings around the station with plaster ceilings and floor plans from the 1920s. Both are a half hour from Grand Central on the Harlem line, which is the whole point.
We serve the county broadly. Larchmont and Rye sit on Long Island Sound with their own housing stock — shingle-style, waterfront colonials, harbor-facing porches. Pelham and Pelham Manor share Bronxville's prewar DNA. Eastchester, Tuckahoe, Harrison, Purchase, Chappaqua and Armonk run north and east into larger properties and newer construction. It is one county with four or five distinct design vocabularies, and they do not borrow well from each other.
INSABELLADESIGN has been doing this since 1996 — a full-service, WBENC-certified woman-owned firm, ASID and IIDA members, based in Little Silver, New Jersey, working across New Jersey, New York, Connecticut and Florida. More than three million square feet designed and over 500 clients, residential and commercial. Beth Insabella Walsh leads every project personally, from the first floor plan to the final install. In a county this detail-conscious, that continuity matters more than anything on a mood board.
What We Design Across Westchester County
Residentially, the recurring problem here is a beautiful old house with a plan nobody would draw today: a kitchen sized for staff, a warren of small rooms at the back, one usable bathroom upstairs, and a third floor doing nothing. We start with space planning — open what should open, keep what should stay a room, and get circulation and daylight right before choosing a single finish. Then the built work: custom kitchens and butler's pantries, primary suites and baths in honed stone, paneled libraries, window seats, built-in storage, mudrooms, stair and ceiling detail, and lighting that respects plaster. Millwork is drawn to match what the house already has — profile, proportion, and hardware appropriate to a 1928 Tudor rather than borrowed from a catalog. Furnishings, rugs, textiles and art follow, and we manage the job through construction and installation.
Our commercial practice runs alongside it. Offices and executive suites, medical and dental practices, professional and financial space, hospitality, and multifamily lobbies and amenity floors — the kind of work found along the Central Avenue corridor, in White Plains, and in the village centers. Those projects add code, ADA, landlord work letters and building standards to the drawing set and run against a lease date. Apartment work in Bronxville and other prewar buildings adds a board and an alteration agreement, which we plan for from day one. We are a design firm, not a staging company: none of this is dressing for a sale.

Westchester County Interior Design — FAQs
How do you handle a Bronxville co-op board and its alteration agreement?
By treating it as part of the design, not an obstacle at the end of it. Prewar buildings in Bronxville and the surrounding villages typically require board approval of drawings, an executed alteration agreement, licensed and insured contractors with certificates on file, an engineer's letter for anything structural or plumbing-related, and often a defined work window with limited hours and freight elevator scheduling. We build the drawing set to what the managing agent and board actually need, flag wet-over-dry restrictions and floor covering rules early, and set the construction schedule around the building's calendar rather than assuming it will bend to ours.
You're in New Jersey. Is that a problem for a Scarsdale or Bronxville project?
No — we have worked across New Jersey, New York, Connecticut and Florida since 1996, and the logistics are routine. Beth is on site for the walkthrough, field measure, demolition review, millwork templating, stone selection and install, and the project runs between visits on drawings, shop-drawing review, and standing calls with your architect, builder and trades. We coordinate with local contractors, cabinetmakers, stone fabricators and expediters where a permit or board filing requires one. It also helps that many clients in this county keep an apartment in Manhattan as well as the house here. Running both through one firm keeps the two places speaking the same language.
Can a Tudor be updated without stripping out its character?
Yes, and the line is usually clear once you see the house. Keep the leaded casements, the plaster, the dark oak stair, the arched openings, the tile around the fireplace — those are the reasons the house is worth the money. Modernize what nobody admires: the kitchen, the baths, the mechanicals, the lighting, the closets, the back-of-house circulation. New millwork gets drawn to the existing profiles so it reads as original. Paint and finish schedules can lift dark rooms considerably without bleaching the woodwork. The failure mode we see most often is a gut renovation that leaves a Tudor exterior wrapped around a plan that belongs in new construction.
What does a whole-home project look like, start to finish?
It begins with a walkthrough and a real conversation about how the house is used — who cooks, who entertains, where the children land after school, what rooms are dead. From there: space planning and floor plans, then design development covering millwork, kitchens and baths, lighting and electrical, plumbing, tile and stone, and finish schedules. We bid and coordinate with your builder, review shop drawings, and stay on the job through construction. Furnishings, window treatments, rugs and art are specified and procured in parallel so install is a single event rather than a year of deliveries. Timelines vary with scope and permitting, but a full-house renovation in Westchester is generally a multi-season project, and we plan it that way from the beginning.
