5K Construction is a Wolverhampton construction company with 10+ years of experience and 500+ completed projects across the West Midlands.
5K Construction is a construction company based at 40A Oaklands Rd, Wolverhampton WV3 0DS. For more than 10 years, our team has built house extensions in Wolverhampton, created loft conversions in Wolverhampton and delivered home renovations in Wolverhampton through our renovation and refurbishment service, with 500+ projects completed across the city and the wider West Midlands.
When you need an extra bedroom, a bigger kitchen or a house that finally works for your family, you want a builder in Wolverhampton who explains the planning approvals before work starts, keeps you updated and finishes what was agreed. That is the standard we hold ourselves to, from a downstairs WC to a double storey extension.
One team manages your project from the first site survey to the final sign-off, so you are not left coordinating bricklayers, plasterers, electricians and plumbers yourself. As building contractors in Wolverhampton, we know local homes and the City of Wolverhampton Council approval process, which keeps your project moving.
Some homeowners need kitchen fitters in Wolverhampton for a single room. Others need a full team for a two-floor extension. 5K Construction covers both, across six core services, with design, building work and finishing managed by the same people from start to finish.
Turn unused roof space into a bedroom, en-suite or home office. We assess your roof structure, head height and stair position, then recommend the right loft conversion for your Wolverhampton home, whether that is a dormer, a hip to gable or a mansard. A structural engineer's calculations cover the new floor joists and any steel beams, and building regulations set the fire escape route. Many loft conversions fall under permitted development, within 40 cubic metres of added roof space for terraced houses and 50 cubic metres for detached and semi-detached homes.

Add living space without the cost and stress of moving. We build single storey and double storey house extensions across Wolverhampton, plus side returns and wrap arounds, with groundworks, structure, roofing and finishing handled by one team. We check whether your extension fits within permitted development or needs planning permission, and whether a party wall notice is needed before work starts.

As kitchen fitters in Wolverhampton, we plan, strip out and fit complete kitchens, including the building work that goes with them. That covers wall removals, plastering, flooring and the coordination of plumbing, with all electrical work completed to Part P of the Building Regulations.

From a compact downstairs WC to a full family bathroom, our bathroom fitters in Wolverhampton handle strip out, first fix, tiling and final fit. Accessible bathrooms and wet rooms are planned around the people who will use them, with waterproofing and ventilation designed in from the start.

We carry out house renovations in Wolverhampton on whole houses and individual floors, from structural alterations and steel beams to final decoration. Older properties often need rewiring, replastering and structural updates, so we survey first, plan the order of works and provide full project management with building control sign-off where it applies.

Smaller projects get the same standard of work. We deliver garage conversions in Wolverhampton, plaster and render walls, lay floors, fit doors and joinery, and decorate inside and out.

Most home projects in Wolverhampton need building regulations approval, and some also need planning permission. Knowing which applies before work starts avoids delays and enforcement problems.
Permitted development lets you extend without a full planning application, within set limits. As of 2026, the main permitted development limits in England are:
| Project | Permitted development limit |
|---|---|
| Single storey rear extension, terraced or semi-detached house | 3 metres (up to 6 metres with prior approval) |
| Single storey rear extension, detached house | 4 metres (up to 8 metres with prior approval) |
| Loft conversion, terraced house | 40 cubic metres of added roof space |
| Loft conversion, detached or semi-detached house | 50 cubic metres of added roof space |
Conservation areas and listed buildings have tighter rules. We check your property before any design work starts.
City of Wolverhampton Council approved 88.7% of the 811 planning decisions it made in 2025. For the category that includes householder applications, the approval rate was 90.3%, and 98.4% of all decisions were made within the statutory time limit.
Nationwide Building Society research published in October 2025 found that a loft conversion or extension adding a double bedroom and bathroom can raise the value of a three-bedroom, one-bathroom house by up to 24%. Adding 10% more floor space adds roughly 5% to a typical home's value.
City of Wolverhampton Council's Building Control team checks that work meets the Building Regulations for structure, fire safety, ventilation, drainage and energy efficiency. Applications are made by Full Plans or, for some simpler work, by Building Notice. All electrical work must also comply with Part P and be carried out by a competent person.
Before you design anything, read our guide to planning permission and building regulations in Wolverhampton, including prior approval and lawful development routes.
Whichever builder you hire, these checks protect your home and your money. Ask us every one of them during your site survey.
Wolverhampton has 31 conservation areas, and 13 of them have Article 4 directions that remove some permitted development rights. On those streets, a rear extension, a dormer or even replacement windows can need planning permission, when the same work a mile away would not. We check your address against City of Wolverhampton Council's conservation area records before any design work starts.
Tettenhall Greens, Tettenhall Wood and Tettenhall Road are all conservation areas with Article 4 directions. Extensions and loft conversions here need designs that respect existing materials, roof lines and street views, and often a full planning application rather than permitted development.
Penn Fields, St Philips (Penn Fields) and Vicarage Road, Penn all have Article 4 directions, and Penn Road (Graiseley) is also a conservation area. Many of Penn's larger family homes suit double storey extensions and loft conversions, so we confirm the planning route first.
Chapel Ash is a conservation area, and The Oaks (Merridale Road) has an Article 4 direction. Period homes in this part of Wolverhampton often need careful renovation of original features alongside modern kitchens and bathrooms.
Castlecroft Gardens has an Article 4 direction and Wightwick Bank is a conservation area. Outside these streets, most homes in this part of the city follow the standard permitted development limits for extensions and loft conversions.
Wednesfield, Bilston Town Centre and the Bilston Canal Corridor are conservation areas, and Bilston Town Centre has an Article 4 direction. For most family homes outside these areas, a single storey rear extension or loft conversion can often go ahead under permitted development.

Not always. Many single storey rear extensions fall under permitted development, up to 3 metres on terraced and semi-detached houses and 4 metres on detached houses, or up to double that with prior approval. Conservation areas and listed buildings have stricter rules. 5K Construction checks your property before any design work starts.
Yes. Every loft conversion needs building regulations approval, even when planning permission is not required. Building control checks the structure, fire escape route, stairs, insulation and ventilation. In Wolverhampton, you can apply through City of Wolverhampton Council's Building Control team. 5K Construction helps you through the application before work begins.
