Core offering

MTA is a London-based, RIBA-chartered architecture practice providing fixed-fee architectural design, planning submission, listed building consent, and full project management services for residential and commercial clients. Its core services cover loft conversions, side and rear extensions, interior refurbishments, listed and historic building works, small residential/mixed-use developments, and commercial fit-outs, delivered through a six-stage process from initial consultation through to handover.

Product overview

MTA (Michael Trentham Architects) is an award-winning, RIBA-chartered architecture practice offering a portfolio of architectural services rather than a software product. The core service offering comprises six interconnected design and build services: Loft Conversions (transforming unused roof space), Side & Rear Extensions (ground floor extensions including side return infills), Interior Refurbishments (full property reconfiguration), Listed & Historic Buildings (heritage and conservation area specialist work), Small Developments (residential and mixed-use schemes for small sites), and Commercial Developments (office, retail, and hospitality projects). These services are delivered through a standardized Six-Stage Design & Build Process (consultation through to handover) and complemented by specialist Sustainable Design capabilities. All services operate on a fixed-fee basis with free initial consultations.
