Full-apartment design
Plan, finishes, lighting, furniture and styling for the whole apartment — one coherent drawing set your contractor can price.
ServicesSmall spaces · Board packages · Built-ins
We design Brooklyn apartments, co-ops and condos — planned to the inch, drawn so your board’s reviewing architect has fewer questions to ask. Design services only: you contract directly with a DCWP-licensed contractor for construction.
Full-apartment design: plan, finishes, lighting and furniture, delivered as one drawing set.
What we do
We only design apartments — prewar walk-ups, elevator co-ops, new condos. It means we already know the questions your managing agent will ask.
Plan, finishes, lighting, furniture and styling for the whole apartment — one coherent drawing set your contractor can price.
ServicesStudios, one-bedrooms and galley kitchens. Built-ins that hold a bed, a desk and a winter coat collection in the same wall.
Small spacesThe design portion of your alteration package, coordinated with your architect, contractor and managing agent.
Board packagesHow a small room comes together
Scroll to watch a 12-by-10 living room assemble in the order we design it — shell, millwork, furniture, light.
Before / after
Same footprint, same plumbing wall — a dropped soffit removed, uppers traded for open shelves and a window brought back into the room. Drag the handle or use the arrow keys.
Concept illustrations — not photographs of a specific apartment. Real before/after photos are published only with the owner's written consent and without identifying the building.
Co-op & condo board packages
An alteration agreement can ask for sealed drawings, the board architect's review, insurance certificates naming the board and managing agent, a security deposit and a work schedule that fits the building. We prepare the design portion and keep everyone's documents moving.
No one can guarantee board approval — not us, not your architect. We help you submit a package that is complete the first time.
Read the package guideSelected work
Three owners, three buildings, all in Brooklyn. Names and addresses stay private; the plans tell the story.
Young family, two remote jobs, one maid's room and a very particular board.
Read the project →A remote worker's studio, separated by one millwork wall and a curtain track.
Read the project →Aging in place, a summer-only work window and two contractor bids that finally matched.
Read the project →Buildings we know
We don't show showroom or brand logos. What we can show is the kind of building we already know how to read, from alteration agreements to riser locations.
Materials
Parquet gets refinished, not covered. Plaster gets patched, not boarded. New work — tile, millwork, brass — is chosen to sit next to 1920s details without pretending to be them.
See the small-space approachWe come to the apartment, measure, and leave you with two layout options for a flat $650, credited to full design if you continue.

Services
Seven ways to work with us. Flat fees where scope is predictable, hourly where it isn't — written into a signed agreement before any work starts.
A two-hour working session in your apartment followed by a measured plan with two layout options and a prioritized list of moves.
Space planning, finishes, lighting, furniture and styling for one apartment, delivered as a complete drawing and specification set.
Layouts, elevations, finish schedules and fixture specs your contractor can bid against, coordinated with your building's alteration rules.
We prepare the design portion of the alteration package and coordinate with your RA/PE, contractor and managing agent. Approval is never guaranteed.
Window seats, closet walls, Murphy-bed walls and bookcases drawn to the inch, with shop-drawing review for your millworker.
Sourcing, ordering, tracking and receiving furniture and lighting. Trade pricing is passed through and our procurement fee is stated up front.
A one-hour video consult for a single room or decision — paint, rug size, layout, lighting — with written notes afterward.
We do not hold a DCWP home improvement contractor license because we never sell, manage or sign construction contracts.
A Virtual Design Hour is the cheapest way to find out.
Home / Small spaces
Small spaces
Studios, one-bedrooms, galley kitchens and the maid's room at the end of the hall. We plan small apartments the way a cabinetmaker plans a drawer.
Millwork detail
An elevation from a typical prewar living-room wall: radiator enclosure, deep seat with drawers, and shelves sized for real books.
Concept drawing, not a construction document. Shop drawings come from your millworker and are reviewed by us.
Millwork, furniture, lighting on existing circuits and finishes usually stay inside a building's "decorative" category. Moving plumbing, gas or walls usually does not — and that's where your RA/PE and board come in. We'll tell you which side of the line each idea falls on before you fall in love with it.
How board packages workHome / Co-op & condo packages
Co-op & condo board packages
Most Brooklyn co-ops and many condos require board approval before renovation work begins. Here is what that usually involves — and which parts we handle.
Every board and its reviewing architect decide independently. We prepare a complete, clear design package and help you anticipate common requests; we do not promise approval or timelines, and no one honestly can.
A planning aid, not legal advice. Your building's alteration agreement governs.

Home / Process
Process
Six steps, each ending with something you can hold: a plan, a set, a schedule. Weeks are typical; your building sets the pace.
Two hours in the apartment. We measure, photograph existing conditions (for our files only) and read your building's alteration agreement with you.
Two to three plans with the trade-offs written next to them. You pick one; we refine it.
Elevations, millwork, lighting, finishes, fixtures and furniture — a complete set, with a budget check at the midpoint.
Your RA/PE seals what needs sealing; we assemble the design portion; two or three DCWP-licensed contractors bid on the same set.
You sign directly with your contractor. We answer questions, review shop drawings and visit site as set out in our agreement.
Deliveries, installation, styling and a punch list. Then we leave you alone in a room that works.
Book a layout consult and leave with two options on paper.
Home / Fees

Home / About
About the studio
Prewar Studio is a small interior and renovation design practice in Brooklyn working only on apartments, co-ops and condos.
We like the buildings most people inherit rather than choose: plaster walls, parquet floors, galley kitchens and the occasional maid's room nobody knows what to do with. Our work is planning to the inch, built-ins that earn their space, and design documents a co-op board and its architect can review without a second round of questions.
We are a design-only studio. Construction is contracted directly between you and a DCWP-licensed home improvement contractor, and sealed drawings and DOB filings come from an independent New York-licensed architect or engineer. We tell you early what a building is likely to allow — and we never promise a board's approval.
Team
Three people in the studio and one independent architect many of our clients hire directly. You’ll meet all of them before anything is signed.
Principal · Interior Designer
Fourteen years designing New York apartments, the last eight leading renovations in prewar co-ops from the Upper West Side to Prospect Heights. Founded Prewar Studio in 2026 to work only on apartments.
Project Designer · Drawings & millwork
Draws every plan, elevation and built-in in the studio and reviews millworkers’ shop drawings line by line. Six years detailing custom cabinetry for Brooklyn workshops.
Studio & Procurement Manager
Runs schedules, orders and deliveries, and the paperwork between clients, managing agents and contractors. Keeps every retainer, invoice and vendor confirmation in one place.
Independent partner architect
A New York-licensed architect who works with many of our clients under his own, separate contract. He prepares sealed drawings and DOB filings where a scope requires them; Prewar Studio does not.

This document describes the rules and disclosures for this particular business and its stated services. Its operational details are drawn from the supplied brand reference; unverified website technology is not represented as active.
This notice concerns Prewar Studio LLC, New York, operating the site prewarstudio.com. Business address: 251 Fifth Avenue, Suite 2B, Brooklyn, NY 11215. Privacy inquiries may be sent to support@prewarstudio.com. Effective year: 2026. The website domain is the current public address; it need not match the company’s legal name.
Prewar Studio LLC operates prewarstudio.com in connection with Brooklyn apartment and co-op interior renovation design. In that setting, relevant individuals include apartment owners, co-op boards and project contractors. The reference describes information such as apartment measurements, interior photographs, board package submissions and design revisions. We do not assume every possible field is collected online: the specific inquiry, booking or enrollment form determines what is actually submitted.
Unless the offering expressly addresses minors through an authorized guardian, the site is not intended to solicit personal information from children under 13. Material changes to actual data practices should be reflected in a revised notice and communicated where required. Inconsistent or inaccurate details should be corrected before this notice is published.
Information connected with small-space layout consultations and apartment design may reveal personal preferences, plans, creative work or commercially sensitive details. Such material should be available only to people who need it to deliver the requested service, respond to an inquiry, maintain records or meet legal duties. A public portfolio or promotional use requires a lawful basis and appropriate permissions; an inquiry alone does not authorize publication.
Relevant purposes include answering requests, arranging services, performing an agreed engagement, maintaining transaction records, detecting abuse and satisfying legal obligations. Promotional messaging is not inferred from merely contacting the business. Any optional marketing signup should explain what will be sent and provide a usable unsubscribe mechanism.
An inquiry or service request can include a name, reply address, telephone number if requested, the requested service, scheduling details and the contents of correspondence. A purchase or paid booking may additionally create transaction identifiers, amounts and payment status. Payment credentials may be handled by a processor; the precise checkout architecture requires verification.
Where service delivery requires outside participants, only necessary details should be shared with relevant instructors, specialists, venues, production partners, carriers or other contracted providers, as applicable to Brooklyn apartment and co-op interior renovation design. This description is conditional on the actual service; it does not assert that all these categories are engaged or that customer lists are sold.
The site is not a general-purpose vault for identity documents, medical histories or other sensitive records. Individuals should avoid submitting unnecessary sensitive information. Where a particular service legitimately requires an accommodation, safety contact, participant permission or other sensitive detail, it should be requested separately, explained at collection and protected appropriately.
Where relevant privacy regimes apply, processing may rest on contract performance, legal obligations, proportionate legitimate interests or consent for activities that require it. Depending on location and legal thresholds, people may have rights to access, correct, delete, receive or restrict data, object, withdraw consent or appeal decisions. Requests go to the contact above, subject to lawful identity checks and exceptions.
The supplied brand reference does not establish an audited cookie inventory or named analytics platform. Essential browser storage may be needed for security or a functional checkout. Any nonessential analytics, marketing pixels or cross-site identifiers must be disclosed accurately and subject to legally required consent or opt-out choices before deployment. This notice does not assert that such tools are active.
Accessing pages may expose an IP address, user-agent information, request time, requested URL and technical error or security records to the site’s infrastructure. These are described as categories that commonly arise in website delivery; no specific hosting provider or tracking product is asserted without a technical inventory.
Information may be shared with providers actually engaged to operate the site or perform a contracted service, and with advisers or authorities when justified. A business transfer may require legally appropriate safeguards. International processing, if any, must satisfy applicable transfer rules. This document does not invent named vendors or claim that customer information is sold.
Information should be kept only as long as needed for the particular engagement, statutory accounting, claims, security or legitimate operational purposes. Retention may vary between service files, correspondence and financial records. Exact periods should be stated only when confirmed. Reasonable access, confidentiality and security measures should be used; absolute security cannot be promised.

2026 · prewarstudio.com · Prewar Studio LLC
This document describes the rules and disclosures for this particular business and its stated services. Its operational details are drawn from the supplied brand reference; unverified website technology is not represented as active.
The operator is Prewar Studio LLC, a business identified in the reference as organized in New York. Its business address is 251 Fifth Avenue, Suite 2B, Brooklyn, NY 11215. The website for these Terms is prewarstudio.com; customer correspondence goes to support@prewarstudio.com. These Terms are dated 2026 and apply subject to any signed engagement terms and nonwaivable consumer protections.
Prewar Studio LLC is associated with Brooklyn apartment and co-op interior renovation design. Website descriptions introduce the offerings; a confirmed booking, enrollment, proposal or other written agreement should identify the purchased scope, dates, deliverables and any exclusions. No website inquiry alone guarantees availability.
These Terms may change prospectively, with the revised date identified. A later website revision does not retroactively rewrite an accepted order without lawful agreement. If a clause is unenforceable, the remainder may remain effective to the extent allowed by law.
The reference lists a flat layout consultation, full-apartment design and per-room renovation design. Crediting consultation fees and cancellation or milestone terms must follow the written engagement, not an assumed general refund rule.
Examples, portfolios, educational descriptions and marketing statements are not guarantees of earnings, professional advancement, artistic success, event conditions or other individualized outcomes. Any express guarantee must be stated clearly and honored as required by law.
Do not misuse payment systems, attempt unauthorized access, distribute malicious software or misrepresent another person. We may take proportionate measures against unlawful activity, without limiting legally protected access or criticism.
Co-op or condo board approval, landlord consent, permits and contractor performance are distinct from interior design services. Board submission packages are not a promise that a building will approve proposed work.
Because small-space layout consultations and apartment design may depend on schedules, participants, third-party resources or customer input, material changes should be documented and handled under the applicable written agreement and mandatory law. Neither a promotional example nor a website overview overrides a confirmed written scope.
Branding, site copy, educational materials, photographs, diagrams, audio and other protectable materials belong to their respective rights holders. Browsing permits ordinary personal viewing, not wholesale commercial copying. Rights in client-created work and final deliverables depend on the relevant project agreement and applicable law.
Customers should supply accurate contact details, relevant specifications and timely decisions for small-space layout consultations and apartment design. Requests beyond the agreed scope may require a separate written quote or schedule adjustment. The provider remains responsible for its own legally required performance and cannot shift all operational risk to the customer.
Customers should give accurate information and use the contact address for scheduling or contractual concerns. Service-specific forms and policies must not contradict the promises made at checkout or in the signed agreement. The separate Privacy Policy describes handling of personal information.
Displayed rates and package examples may depend on scope, location, timing or availability. Taxes, third-party charges, materials, travel and other material costs should be itemized before acceptance where relevant. Changes to a confirmed order require an appropriate contractual basis or customer agreement.
Nothing in these Terms removes statutory refund rights, liability for fraud or willful misconduct, or other obligations that cannot be excluded. Any permitted limitation must be interpreted narrowly. Contact the business to raise concerns; no mandatory arbitration, class waiver or exclusive jurisdiction is invented here.
Some services depend on independent venues, platforms, suppliers or specialists. The relevant written agreement should allocate duties transparently. Mention of a third party is not an endorsement or a guarantee of that party’s performance; mandatory duties of the operator cannot be waived by simply naming a vendor.
Descriptions and starting prices invite inquiries or orders but do not themselves reserve a place or create a fully scoped engagement. A binding commitment arises under the actual checkout, written confirmation or signed service agreement, subject to applicable law. Any deposit, recurring charge or automatic renewal must be clearly disclosed before consent.
