What MAD architects llp does

MAD Architects LLP is a UK-based architectural practice founded in 2012 and headquartered in Chesterfield, operating across South Yorkshire, North East Derbyshire, and the Peak District. The firm is RIBA Chartered and led by partners Martin Rix and Eliza Sophocleous, with combined experience of approximately 20 years. It provides residential architectural services — including extensions, renovations, new builds, Passivhaus design, planning-permission support, and barn conversions — to private homeowners in the Sheffield, Chesterfield, Peak District, North East Derbyshire, and Bolsover corridor. The practice differentiates through energy-efficient Passivhaus design capability and use of 3D Building Information Modeling (BIM) technology for design documentation and client visualization.

The firm's revenue model is project-based professional fees charged to private residential clients on a sales-led, consultative basis, with customer acquisition occurring primarily through organic channels including regional SEO-optimized location pages, local reputation, referral, and historical editorial coverage in publications such as Real Homes and Self Build & Design (2016). Headcount is reported in the 1-10 employee band, consistent with a small partnership structure, and no funding rounds or external investment are disclosed. The practice maintains a technology stack of 3D BIM alongside mainstream marketing tools (Squarespace, Mailchimp, Stripe, Google Analytics) and has formed a product specification partnership with ecoHaus SW (Internorm) for triple-glazed window systems.

The most recent observable commercial activity is a June 2024 website relaunch representing the firm's fourth iteration, signaling an active repositioning effort. Geographic expansion has been pursued through dedicated location pages rather than new offices, and service-line expansion has emphasized Passivhaus specialization rather than horizontal service broadening. The practice operates as an independent, privately-held partnership with no M&A, joint-venture, or institutional-investment signals in the available record.
