What our clients say

MI&A transformed our cramped Victorian terrace into a stunning open-plan home. Their attention to detail with the structural design was exceptional, and they managed the entire approvals process seamlessly.

James & Sarah Mitchell
Residential Extension — Islington

Professional, communicative, and incredibly knowledgeable. The structural calculations were delivered promptly and building control had zero issues. I've recommended them to every developer I know.

David Reynolds
Property Developer — Hackney

From our loft conversion plans through to the party wall agreements and site inspections, MI&A handled everything. The 3D visualisations helped us see exactly what we were getting before a single brick was laid.
