RIDDLE CONSTRUCTION & DESIGN LLC

What RIDDLE CONSTRUCTION & DESIGN LLC does

Riddle Construction & Design LLC is a privately held, family-owned design-build residential remodeling firm headquartered in Redmond, Washington, operating continuously since 1976. The company delivers integrated design and construction services for kitchen, bathroom, whole-house, and addition projects, primarily serving homeowners across Redmond, Bellevue, and the surrounding Eastside Washington communities. Its service offering combines in-house design (led by Chris Riddle, a designer since 1988 and NKBA Certified Master Kitchen & Bath Designer) with fixed-bid construction execution under general contractor Curt Riddle, who brings more than 35 years of field experience; next-generation family member Josh Riddle supports the business as a project manager. Certifications include Lead Safe Firm status and NKBA Certified Member designation, which together expand the addressable housing stock and signal professional credibility.

The business model rests on a multi-stage monetization flow: an initial design retainer of $3,000 to $6,000, a project development fee of $3,000 to $5,000, and a fixed-bid construction contract for the build phase. The firm currently operates with approximately 5 employees and maintains long-tenured vendor relationships, including a preferred-contractor arrangement with AGS Stainless Inc. for stainless kitchen and bath product scopes. Lead generation is anchored by an established Houzz presence, evidenced by 11 consecutive Best of Houzz awards from 2014 through 2025 and 50,000+ ideabook saves, supplemented by sustained recognition through NKBA and REX industry awards.

The company does not disclose revenue, has not pursued external funding, and operates entirely within the Eastside Washington residential remodeling market. There is no public indication of geographic expansion, technology platform development, AI or data-analytics capabilities, or M&A activity. Its competitive positioning is built on multi-decade family expertise, integrated design-build delivery, and durable brand equity earned through repeated third-party recognition rather than on scale, technology differentiation, or multi-market reach.
