Got Questions?

Frequently asked questions

Straightforward answers about planning, costs, timelines, and site management.

Many loft conversions and ground-floor extensions fall within Permitted Development rights, meaning full planning permission isn't required. If your property is in a designated conservation area, listed, or exceeds standard volume thresholds, we handle the entire architectural submission and council liaison on your behalf.
