Do you need planning permission for a house extension?
A plain-English guide to permitted development for house extensions in England: the size limits, when you need a full planning
Home extensions, loft conversions, kitchens, bathrooms and full renovations, planned and built by one team from first visit to handover.
Most building projects involve several trades and a long list of decisions. Our job is to keep all of it joined up, with a clear scope at the start, steady communication in the middle and a proper handover at the end.
Seven services, one team. Most projects mix a few of them, and that is exactly the kind of work we coordinate.
Single and double storey, open-plan and garden-facing.
Dormers and roof spaces turned into real rooms.
Layout, services and finish, built around how you live.
Bathrooms and en-suites with durable, clean detailing.
Whole-home changes that make the house work harder.
A considered refresh for performance, flow and finish.
Masonry, structural work, repairs and groundworks.
Plain-English guides to planning permission, Building Regulations, loft conversions and what to expect on site.

A plain-English guide to permitted development for house extensions in England: the size limits, when you need a full planning

The main types of loft conversion, what each one suits, when they need planning permission and what Building Regulations require.

Planning permission decides whether you can build. Building Regulations decide how it must be built. Here is how the two

From frame to finish
Photographed on our sites: the structure going in, the roof opening up, insulation, through to the finished rear elevation.

New rafters and roof-light openings bring daylight into the loft.
Foil-backed insulation boards fitted between the rafters.

Structural openings, steelwork, roof lanterns, wide sliding doors and floors carried through the house. When the building work and the finish are planned together, new rooms feel like they always belonged.

Where we work
Our team and vans are on sites across the region every week. If you are near one of these, we would be glad to come and see your home.
Something else on your mind? Our assistant can answer the basics instantly, and hands anything specific straight to the team on WhatsApp.
Every home is different, so we do not publish set prices. Cost depends on size, structure, finishes and access. After a free conversation and site visit, we give you a written quote with a clear scope, so you can see exactly what is included.
Some extensions and loft conversions can go ahead under permitted development, while others need full planning permission. It depends on the size, position and the property itself, and Building Regulations approval is usually needed either way. We talk it through with you at the site visit.
It depends on the scale of the work and what approvals are needed. Before anything starts we agree a build programme with you, so you know the sequence of work and roughly when each stage happens.
Often, yes. It depends on the scope and which rooms are affected. We explain how the work will be sequenced at quote stage so you know what to expect and can plan around it.
