What Green Code Architects does

Green Code Holdings Limited, operating as Green Code Architects, is a UK private limited company incorporated in 2022 (Company Number 13312452) that runs a multi-disciplinary architecture, engineering, and property development practice headquartered in London with a secondary London office and a delivery presence in Sri Lanka. The company is organized into three core divisions: Architecture (Green Code Architects), Engineering (Green Code Engineering), and Development (Green Code Development), supported by a Consultants subsidiary (Green Code Consultants Ltd) and the acquired F line Designs Ltd for structural drawings and calculations. Its services span residential extensions and new builds, commercial projects across education, healthcare, hospitality, food and beverage, retail, and workplaces, urban design and master planning, heritage and conservation, mixed-use developments, and community facilities, as well as structural engineering, basement impact assessments, and party wall matters.

The firm's underlying technology is conventional for the sector: laser scanners with 25mm and 50mm tolerances for measurement, CAD and Revit for design documentation, and modern construction techniques. There is no proprietary technology platform, no AI/ML capability disclosed, and no patents or trademarks. Green Code markets sustainability as a core differentiator, aligning with the British Property Federation's Net-Zero Pledge and embedding environmentally conscious design throughout its service lines.

Green Code generates revenue through project-based professional services fees across its three divisions, generally on milestone-based terms (50% advance before project start, 50% before document release or submission). The firm publishes hourly rates (£135/hr for Directors, £105/hr for Structural Engineers, £95/hr for Architects and Architectural Technologists, £80/hr for Architectural Assistants), charges £550+VAT per additional site visit, applies a 5% administration fee on third-party reports, and issues fee proposals valid for 60 days. Pricing is quote-based and project-specific, with projects under £1,000+VAT paid in full upfront. Customer mix is split between private individuals (residential) and business customers (commercial, education, healthcare, hospitality), with project sizes ranging from small residential alterations to multi-million pound commercial developments. Go-to-market is primarily direct, enterprise-style field sales driven by website enquiries, a portfolio of 12+ completed projects, and dedicated project managers assigned to each client.
