What the job involves
We build brick, stone, glazed and oak-framed porches that match the house, on proper foundations, with the permitted development check done first.
On period and stone properties in and around the conservation area, a porch has to be sympathetic — matched limestone or brick, a pitched and slated roof, and timber or slim-framed glazing. A clumsy uPVC box on a Georgian frontage looks wrong and can cause planning problems; we build to suit the age of the house.
On Victorian and Edwardian villas, an enclosed porch over the original front step adds insulation and storage while keeping the period detail. We retain or replicate features like tiled thresholds and decorative brick where they exist.
On modern estates around Casterton Road and the town edges, a porch is often a simple, practical addition — brick to match, a tiled lean-to or pitched roof, and a composite door. These are frequently permitted development and quick to build.
When does a porch need approval?
A porch is generally permitted development, and exempt from Building Regulations, if its floor area is under three square metres, it sits more than two metres from a road or boundary, and the front door between porch and house stays in place. Larger porches, or those on listed and some conservation-area properties, need approval — and we handle that side rather than leaving it to you.

Building control and planning advice by council
A porch under 3m² footprint, under 3m high and at least 2m from a boundary facing a road is usually permitted development (Planning Portal: porches). Stamford's conservation area Article 4 direction removes that for porches facing a road, and several Rutland villages have Article 4 directions too.
