What MainStreet Design Build does
MainStreet Design Build is a privately held luxury design-build home remodeling firm founded in 1991 and headquartered in the Birmingham/Bloomfield Hills, Michigan area, serving affluent homeowners throughout Southeast Oakland County across roughly fifteen named communities including Birmingham, Bloomfield Hills, Royal Oak, Troy, Grosse Pointe, Rochester Hills, and Huntington Woods. The firm operates an integrated design-build model in which in-house architects, interior designers, and construction craftspeople collaborate from initial concept through final construction, eliminating the traditional handoff between separate architect, designer, and contractor entities. Core service lines span Kitchen Remodeling, Bathroom Remodeling, Basement Remodeling, Interior Design, Exterior Renovation, Home Additions (including second-story and over-garage additions), and a higher-end Architectural Remodeling line for whole-house renovations and structural modifications; the firm differentiates via an in-house virtual design presentation that lets clients visualize finished work before construction begins.
The business model is project-based and direct-to-consumer: the firm generates revenue through one-time fees tied to each remodeling project, with project costs established during a structured design phase before construction begins, reducing the risk of mid-build budget overruns. Go-to-market is consultative and sales-led, beginning with free initial consultations followed by a paid Design Agreement, supported by a multi-channel marketing footprint that includes the corporate website, active social profiles on Facebook, Instagram, LinkedIn, Pinterest, YouTube, and Houzz, a newsletter, downloadable educational eBooks (Design Investment Guide, Top 20 Remodeling Mistakes, Design Build vs Design-Bid-Build), virtual consultations, and a referral network of personal, professional, client, and trade-show sources. Customers are individual mid-market and high-net-worth residential homeowners; pricing is project-specific and not publicly disclosed. Leadership consists of founders Steve Ramaekers (Creative Director of Design, a former carpenter) and Christine Ramaekers (Creative Director of Interior Design), supported by General Manager Kim McDevitt and tenured in-house staff with average tenure exceeding ten years. The firm reports no external funding, no M&A activity, and no disclosed institutional ownership, and in 2026 is relocating its primary office from Birmingham to Bloomfield Hills.
