What Curtis & Windham Architects does

Curtis & Windham Architects is a Houston-based architecture firm founded in 1992 by William Curtis and Russell Windham that specializes in classical and traditional design for private residences, estates, institutional buildings, and select commercial projects. The firm operates an integrated multidisciplinary practice comprising four service lines: Architecture, Landscape Architecture (established 2005), Interior Design, and Construction Management, with hands-on principal involvement from initial site assessment through project completion. Its primary customer segment is high-net-worth individuals and families seeking bespoke classical residences, with secondary segments in institutional clients (schools, churches) and commercial clients (restaurants, offices). Geographic reach spans Texas, California, Colorado, New Mexico, Florida, Montana, and the Cotswolds in the United Kingdom, despite operating from a single Houston headquarters at 3815 Montrose Blvd.

The firm employs between 11 and 50 staff, including a team of architects, landscape architects, interior designers, and administrative personnel, with no disclosed external institutional investors, private equity involvement, or parent company. The business model is project-based fee-for-service with pricing negotiated per engagement and not publicly disclosed; the firm does not list customers, indicating a direct-inquiry model in which prospective clients initiate contact via the website inquiry form, email, or phone. The firm does not offer any public APIs, software products, or technology platforms, and its core outputs are design drawings, specifications, and built works.

Curtis & Windham has accumulated substantial industry recognition, including the Arthur Ross Award for excellence in classical architecture from the Institute of Classical Architecture & Art, multiple John Staub Awards (ICAA Texas, 2011, 2013, 2015, 2019), and a 2014 Palladio Award. The firm has been featured in Architectural Digest, ELLE Decor, House Beautiful, Veranda, Southern Living, Forbes, Paper City, and Milieu Magazine, and has published two Rizzoli monographs, 'A Vision of Place' and 'Building on Tradition' (2026), documenting its portfolio. Marketing is primarily organic, centered on the portfolio website, an active Instagram presence, book distribution, editorial coverage, and design-event participation.
