What Design Lines, Inc. does
Design Lines, Inc., doing business as TRIO, is a Denver, Colorado-based interior design firm founded in 1999 by Angela Harris. The firm specializes in interior design services for model homes, multifamily developments, clubhouses, senior living communities, and luxury residential projects, and serves large production builders, developers, and architects across the United States on a coast-to-coast basis. Notable enterprise clients include Toll Brothers, Brookfield Residential, AMLI Residential, Carmel Partners, and the Storyliving by Disney Cotino community delivered in partnership with Shea Homes.
The firm operates on a project-based, quote-based pricing model delivered through a B2B enterprise field-sales motion. Its service offering is structured around three modules: Branding & Marketing, Design Services, and Logistics, supported by a multidisciplinary team of artists, visual architects, and innovators. Revenue mechanics are driven by individual builder project pipelines rather than recurring contracts, and the firm's recent positioning has been reinforced by industry recognition including the Interior Design magazine 2026 Top 100 Giants of Design list and a 2025 Bisnow Icon Award.
Firmographic data lists the company at 14 employees, which is materially inconsistent with claimed national builder accounts and Top 100 Giants status; this discrepancy is itself an analytical signal that the available data is incomplete or that headcount reporting is understated. There is no evidence of proprietary technology, AI/ML capabilities, or recurring software revenue in the input data.

Design Lines, Inc. competitors and assessment

- Perceptive Group: A B2B interior design and merchandising firm that designs model homes and community spaces for production homebuilders. Directly comparable to TRIO because it serves the same production builder customer base with model home and amenity interior design services.
- Canopy Marketing: Model home merchandising and interior design firm serving residential builders and developers. Comparable to TRIO in target customer (production builders), service scope (model home design), and go-to-market (B2B enterprise sales to developer accounts).
- Black Lacquer Design: Interior design firm specializing in model homes, multifamily, and builder/developer projects. Directly comparable to TRIO across the same vertical segments and customer type.
- Lita Dirks & Co. Interior design firm that creates model home interiors and merchandising for homebuilders. Comparable to TRIO in both service offering (model home interior design) and B2B relationship with production builder clients.
