Before you reach out

Common questions about working with us.

A few quick answers to the questions we get asked most.

How quickly will I hear back?
Within 2 working hours during business hours. After hours and weekend enquiries are answered first thing the next working day.
What do you need to send a quote?
Existing & proposed drawings (any format), site address, and a brief on what you need. That's enough for a fixed quote within 24 hours.
Do you take on small / homeowner projects?
Yes — about a third of our work is homeowner extensions and loft conversions. Senior expertise applied at the same standard, scaled to project size.
Do you work outside London?
Absolutely. We deliver UK-wide — our cloud-based delivery model means we can serve any LPA without needing to be on site.
