Kitchen Extensions Luton

A kitchen extension in Luton is mostly a job on a house: 72% of homes here are houses, 30% terraced and 38% semi-detached or detached. The pre-1919 terraces near the centre take a side infill or a short rear addition; the interwar and post-war semis take a deeper rear addition or a wraparound. Luton Borough Council is the planning authority and runs its own building control service, and where an application is needed its Local Plan sets the tests for the roof and for your neighbours. We build the shell, the steel and the kitchen as one programme.

For Luton, on London-derived ranges a rear kitchen extension of about 30 square metres typically costs £45,000 to £97,500 excluding VAT, or £60,000 to £100,000 for a side return; Bedfordshire work generally runs below that. GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Luton: the structural engineer we appoint designs the foundations and steel, we build the room and fit the kitchen, and a registered electrician certifies the electrics.

The roof has to match the house in Luton

Where your kitchen extension needs planning permission, Luton Local Plan Policy LLP19 asks for a roof whose style and pitch are in keeping with the original roof. That makes the roof an early design decision rather than a detail. On a pitched roof interwar semi, the designer has to show how a lean-to, a pitched roof or a flat roof sits with the house, and the planning officer judges the fit. The shape chosen then sets the ceiling line inside, where roof lights can go and how high the wall plate lands on the rear wall.

A rear extension inside the permitted development limits needs no planning application, and LLP19 is not then the test; the national condition is that exterior materials look similar to the house. If you are unsure whether your address still has those rights, Luton Borough Council offers technical advice confirming whether they have been restricted. Luton has no householder extension design guide among its supplementary planning documents, so on an application the Local Plan policy is the text your designer works to. We price the roof from those drawings: rafters or a steel ridge, matching tiles and lead flashing to the house.

A listed building is the exception: work that affects its character, inside or out, including an extension or taking out a wall or chimney breast, needs listed building consent from Luton Borough Council, and doing it without consent is a criminal offence.

Housing in Luton

Luton's housing, as the Council Tax list records it, is about 85,500 homes: 72% houses, 28% flats, with 13% pre-1919, 20% interwar and 67% built since 1945. 30% of homes here are terraced; a terrace kitchen extension in Luton starts in a narrow side return.

Neighbours, light and privacy on a Luton rear extension

Policy LLP19 also says an extension must not harm neighbours through visual intrusion, loss of light, loss of privacy or overlooking, particularly of habitable rooms and patio areas. On a Luton terrace or a pair of semis, the neighbour's kitchen window and patio can be a few metres from your new side wall. That is why depth, wall height on the boundary and the position of any side window matter as much as the kitchen layout.

In practice a Luton kitchen extension that sits close to a neighbour's patio may be drawn with a lower eaves on that side, obscure glazing or no side window at all, and the roof lights doing the work instead. We build to whatever the approved drawings show and we set the boundary wall out on day one, so there is no drift toward the neighbour during the build. Talk to next door early; where the Party Wall Act applies to the footings or the boundary wall, you as building owner serve the notices.

Chalk, river alluvium and the Luton footings

Luton sits on Chalk bedrock rather than London Clay, so the shrink and swell subsidence pattern of north London is not the default starting point for your foundations. Along the River Lea corridor through Leagrave, Wardown Park and the Kimpton Road area, though, alluvium of clay, silt, sand and gravel is mapped, and that ground behaves differently. What lies over the chalk still varies from plot to plot, so the structural engineer we appoint looks at what the trial hole shows before the foundation design is settled.

Where Luton Borough Council is your building control body, its inspection schedule for an extension sets stage 2 as the check of the new excavation for foundations. Stage 4 covers the new walls, the damp proof course and the below ground drain pipes for falls and line. We book those visits in sequence so the trench is open when the surveyor arrives and the drains are left exposed until they are passed. On a Luton kitchen job the drains matter twice: the new sink run and the gully outside.

Faster householder decisions in Luton, with one exception

Where your kitchen extension needs planning permission, Luton Borough Council offers a fast track householder application that commits to a decision within five working days of the end of the consultation period. That shortens the wait between drawings and a start date. The fast track has to be requested in the proposal description when the application goes in, so your designer or agent needs to know you want it before they submit.

It is not available where the property sits in a conservation area. Luton has five, and the two primarily residential ones are Rothesay and Luton South, so a house there follows the ordinary route. In a conservation area, changes that would be permitted development elsewhere, such as cladding or roof alterations, need planning permission. Once a decision is in hand we can fix the start, order the steel and the kitchen, and book the first building control visit. We plan the programme from the decision date, not from the date the application was lodged.

The GS Renovation Difference in Luton

You get one team for the whole kitchen extension in Luton: groundwork, drainage, the steel into the back of the house, the roof, the glazing and then the kitchen itself. We work from your designer's approved drawings and the structural engineer's calculations, and we book each building control stage so nothing is covered before it has been seen. You get a written programme at the start, one point of contact, and the kitchen fitted in the same sequence rather than as a second job months later.

• Building control and Part P certificates handed over together at the end
• Our own trades on site rather than a chain of subcontractors
• New floor level matched to the existing house, with no step at the opening
