studio: MASS

Launch summary

Studio Mass is a London-based residential design practice led by an architectural technologist, specialising in extensions and renovations for period properties across the city. We work primarily with homeowners who want to create more space, improve how their homes function, and protect the long-term value of their property—without the uncertainty that typically comes with complex building projects. Our services cover the full process: initial design, planning consent, technical construction packages, Building Regulations approval, and site coordination through to completion. The emphasis throughout is on buildability, cost clarity, and design decisions that are resolved early to avoid problems later. Typical projects include rear and side return extensions, basement conversions, loft conversions, and whole-house refurbishments—predominantly within Victorian and Edwardian terraced homes across London's residential zones. We position ourselves as the technical lead on complex residential work: the filter between homeowners and contractors, the person who sees around corners, and the professional who makes the process predictable when it's typically anything but.
