Model 01 Garden-Level Kitchen · Crown Heights Duplex Built 2025 · digitized from the finished project

Brooklyn, New York · Kitchens · Baths · Brownstones

Beautifully built healthy homes.

Kitchens, baths, and brownstone renovations by one Brooklyn team, from first sketch to final tile. Before a wall opens we check what's behind it: moisture, air, heat loss. The room looks right, and stays right.

§01 · Method

Three phases. One team.
No handoffs. No guesswork.

  1. 01

    Diagnose

    We walk your home with thermal imaging, moisture meters, and air-quality sensors before a wall is opened. Every project starts as a dataset.

    • Thermal survey
    • Moisture map
    • IAQ baseline
    • Existing conditions
  2. 02

    Design

    Diagnostic findings drive envelope and material decisions; a creative spatial pass solves the layout: brownstone floor plates, galley kitchens, walk-up footprints.

    • Spatial design
    • Envelope spec
    • DOB coordination
    • Low-VOC materials
  3. 03

    Build & Verify

    We build what we designed, then prove it worked with post-construction testing on moisture, air, and performance. Every project ends with data, not a walkthrough.

    • Licensed build
    • Remediate first
    • Post-test
    • Performance report

§02 · Casework

Brownstones, walk-ups, lofts, high-rises.
Across New York.

§03 · Casebook

Rooms we build.
Problems we solve on the way.

Case 01

Kitchens & baths

Layouts that work harder per square foot: islands that do three jobs, storage pulled from dead corners, sight lines opened. Specified for moisture-heavy NYC rooms.

Case 02

Brownstone reconfiguration

Wall removals that respect period millwork; modern programs inside 19th-century floor plates, without losing the bones worth keeping.

Case 03

Basement & cellar finishing

Equal parts spatial puzzle and moisture problem. We solve both: assemblies that manage water, programmed for how you'll actually use the space.

Case 04

Cold drafts & energy loss

Your brownstone is losing heat through pathways thermal imaging can see. We seal the envelope where it matters and design ventilation that works with the building.

Case 05

Indoor air quality

Headaches, allergies, the smell you can't place. We test particulates, VOCs, humidity, and CO₂, then specify materials and ventilation to fix it.

Case 06

Your home

Tell us what you want to change. We'll bring the drawings, and the instruments.

§04 · Studio

An environmental scientist and an architect walk onto your job site.

That's not a joke. It's the firm. Contractors build without diagnosing; consultants diagnose without building. Proteus does both, with a designer's pass in the middle, so nothing is lost between the person who found the problem and the person who fixes it.

Will Dunphy brings a Master's in Sustainable Communities: environmental science, GIS, building health diagnostics. His father brings a Master's in Architecture and decades of design inside NYC's pre-war stock.

We're not the cheapest contractor in Brooklyn. We're the one who shows you what's happening inside your walls.

§05 · Consultation

Tell us about
your project.

We visit, listen, and measure. You leave with a design direction, an honest number, and a read on what's behind your walls.

Free visit. No obligation. No pitch.
