NK Woodworking & Design

What NK Woodworking & Design does

NK Woodworking & Design is a Seattle-based custom architectural millwork firm founded in 2011 by Nathie Katzoff. It designs and fabricates sculptural staircases, wood bathtubs, and bespoke furniture for high-net-worth residential clients, serving homeowners, architects, interior designers, and luxury home builders. The firm produces work in a 12,000 sq.ft Seattle workshop supported by an LA satellite, and has won the Stairbuilders and Manufacturers Association (SMA) stair design competition in 2014, 2015, and 2016. Its stated technical approach pairs CAD/3D modeling and structural engineering with hand craftsmanship, and it has developed a proprietary waterproof finishing system that enables the wood-bathtub product category. Distribution spans direct project commissions plus retail showrooms at PIRCH (Oceanside, CA) and the Nathie Katzoff Art Gallery (Beverly Hills), with shipping and installation across the continental U.S., Hawaii, Alaska, Canada, and select international locations.

The business model is project-based custom fabrication priced per commission at the high end of the luxury residential build market, with no disclosed standard pricing, retainers, or subscription revenue. The firm is founder-owned; no outside investors, funding rounds, debt instruments, or M&A activity are disclosed in the input. Headcount is reported at 1-10 employees, consistent with a small atelier-scale operation rather than a scaled manufacturer. The introduction of a branded bathtub line (NK Bath / Lotus Bath Collection) and the addition of permanent retail/brand venues mark the most significant shift from pure custom millwork toward a hybrid custom-plus-product model.

Direct peers

• Viewrail: Goshen, IN-based designer and manufacturer of modern stair systems, glass railings, and floating staircase hardware. Direct peer in the architectural staircase category, though more standardized/modular versus NK's fully sculptural approach.
• BDDW: Philadelphia-based maker of hand-built furniture and architectural millwork with a similar ultra-custom, craft-driven approach. BDDW produces made-to-order pieces for high-end residential and hospitality clients, mirroring NK Woodworking's bespoke, art-meets-architecture positioning.
• Arcways: Canadian fabricator specializing in custom curved and spiral staircases. Direct peer in the high-end custom staircase category, with comparable use of wood, metal, and glass in sculptural configurations.
• The Joinery: Portland, OR manufacturer of custom wood furniture and architectural millwork with a comparable craft philosophy and B Corp values. Direct overlap in custom wood furniture, cabinetry, and millwork for design-conscious residential clients.
• Wooden Bath: Specialist manufacturer of wooden bathtubs—the closest direct peer to NK's Lotus Bath Collection. Both serve the luxury bath segment with handcrafted wood tubs, though Wooden Bath operates more in European/standard designs versus NK's sculptural, art-object positioning.

Broad incumbents

• BainUltra: Canadian manufacturer of luxury bathtubs, including therapeutic and air-jetted models. A broader incumbent in the luxury bath space NK is entering with the Lotus Bath Collection, though BainUltra does not make wood tubs.
• Smallbone of Devizes: UK-based luxury cabinetry and joinery maker serving super-prime residential projects globally. Comparable in bespoke craftsmanship and HNW client base, though more focused on kitchens and freestanding furniture versus NK's architectural sculpture.
• DeVOL Kitchens: UK luxury kitchen and cabinetry designer with a comparable handmade, design-forward reputation. Overlaps with NK Woodworking in the high-end residential millwork and custom furniture categories.
• Clive Christian: Established UK luxury furniture and kitchen cabinetry brand with a comparable premium positioning, handcrafted production model, and design-led reputation. Broader and more diversified than NK Woodworking, but addresses overlapping HNW residential customers.

Emerging players

• Premier Copper Products: Arizona-based maker of luxury copper, brass, and nickel bathtubs and sinks targeting high-end residential remodels and new construction. Comparable in premium bath product positioning, though material focus (metal vs. wood) differs.
