What porch extensions in Corby usually involve
A good porch keeps draughts and rain out of the hall, gives you somewhere for coats and boots and smartens the front of the house. We build brick, rendered and glazed porches across Corby and the Northamptonshire villages, designed to match the property and built to last. Many porches are permitted development and the smallest are exempt from Building Regulations — we confirm exactly where yours sits before any work starts.
Porches designed for Corby homes
Corby is mostly modern and post-war housing with older homes in the villages, and the right porch looks different on each.
On modern and estate homes, a brick-and-tile or glazed porch with a composite door is usually straightforward, quick to build and often permitted development — a practical, smart addition to a standard frontage.
On older and village properties around Weldon, Gretton and Cottingham, a porch should be built in matched brick or render with a pitched, tiled roof so it reads as part of the original building.
Glazed porches suit homeowners who want the light and the shelter while keeping the entrance feeling open — we build these with a low brick base and safety glazing throughout.
When does a porch need approval?
A porch is generally permitted development if it is under three square metres, no more than three metres high and more than two metres from a boundary next to a road. It is usually exempt from Building Regulations too if it is under 30 square metres and the original front door is kept between the porch and house. Larger porches, and those on listed or conservation-area homes, need approval, which we arrange for you.

Ground, drainage and conservation in Corby
Corby sits on the Northampton Sand ironstone that fed the steelworks, and large areas around the town were opencast quarried and restored. Ground can change from natural ironstone to clay or fill within a garden, so we dig before we design the base and drainage.
Corby has nine conservation areas, including the Old Village, Cottingham and Middleton, Gretton, Rockingham, Stanion, Great Oakley and Weldon. Its only Article 4 direction (Kingswood) controls houses in multiple occupation and does not affect driveways, porches or extensions.
The Willow Brook runs through Corby and Weldon, with an Environment Agency flood storage reservoir at Weldon, so properties near the brook need drainage planned with care. You can check any address on the Environment Agency flood map.
