Do I need planning permission for my extension or new build?

Do you offer snagging inspections for new-build homes?

Yes — a technologist-led inspection of a newly built home before or shortly after legal completion, checking construction quality and finish against the specification and building regulations.

What's a fabric-first approach to sustainable design?

Treating the building's fabric — insulation, airtightness, glazing, thermal bridging — as the foundation of energy performance, before adding renewable technology on top, in line with Passivhaus and AECB principles.

How long does a typical residential project take?
