Stewart Design Group

What Stewart Design Group does

Stewart Design Group is a private, founder-led interior design firm headquartered in Kennebunkport, Maine, established in 1992 by principal designer Cathleen Stewart. The firm provides full-service interior design across two segments: commercial clients (financial institutions, law firms, and small businesses seeking brand-aligned workspace design) and residential homeowners in the New England region. Service offerings span design consulting, space planning, construction planning, architectural renderings, furniture planning and acquisition, color and paint consultation, and a proprietary Visual Thumbprint intake exercise that channels client aesthetic preferences.

The firm's product surface is organized into three pillars: Design Services (residential and commercial interior design, specifications, renderings), Custom Services (upholstery, window treatments, cabinetry, millwork, decorative painting, glass and metal fabrication), and Design Products (curated furniture, lighting, fabrics, wall coverings, flooring, and fixtures). A long-running real estate staging service for high-end Boston-area properties and historical design education classes round out the offering. Notable commercial work includes interiors for Enterprise Bank that contributed to repeated Boston Globe Top Places to Work recognition.

The business operates on a professional services revenue model, generating fees through design consultations and project work, with no publicly disclosed pricing. Go-to-market is sales-led via direct consultation, supported by a website-based portfolio and inbound contact form. Distribution is regional and constrained to New England, with delivery centered on the founder and a small team (firm size listed at 11-50 employees). The firm is bootstrapped with no external funding, no parent company, and no disclosed institutional ownership.

Direct peers

• Decorating Den Interiors: North American interior design franchise with hundreds of owner-operator designers serving both residential and small-business clients. Directly comparable to Stewart Design Group's boutique, designer-led residential and commercial model, differing mainly via the franchise/owner-operator structure.

Broad incumbents

• La-Z-Boy Interior Design Service: Major furniture retailer offering free interior design consultations as a value-add to furniture purchases. Overlaps SDG's residential design and furniture-procurement offering, but La-Z-Boy is anchored in retail rather than a designer-led boutique practice.
• Ethan Allen Interiors: National furniture manufacturer and retailer with in-house interior design services at every location. Competes across both residential design and furniture acquisition, with far greater scale and brand recognition than SDG.
• RH (Restoration Hardware): Luxury home furnishings brand offering complimentary in-home and showroom-based interior design services (RH Interiors) for high-net-worth clients. Comparable in targeting premium residential and commercial-brand customers.
• West Elm (Interior Design Service): Williams-Sonoma-owned modern home furnishings retailer with a free in-store design service. Comparable to SDG on residential design and furniture/decor sourcing, with significantly larger product catalog and brand reach.
• Pottery Barn Design Services: Williams-Sonoma home brand offering free interior design services for residential and small commercial clients. Competes for the residential portion of SDG's client base, with retail-channel scale advantages.

Emerging players

• Havenly: Online interior design platform matching clients with vetted designers for flat-fee room packages. Competes with SDG for residential design clients, particularly younger/tech-comfortable homeowners, but with a scalable tech-enabled model.
• Modsy: Tech-enabled interior design service using 3D renderings of customers' rooms. Targets the same residential client base as SDG's residential practice but substitutes algorithmic visualization for in-person consultations.
• Decorilla: Online marketplace connecting consumers with multiple interior designers who compete on room concepts. Overlaps SDG's residential design offering but delivers services virtually at lower price points.

Regional players

• California Closets: Custom storage and closet design franchise serving residential clients across North America. Adjacent to SDG's custom design and millwork offerings but narrower scope (storage-focused).
