Looking for builders in Wolverhampton who know the difference between a Victorian villa on Tettenhall Road and a 1930s semi in Finchfield?

Open Mon-Fri 8am-6pm, Sat 8am-2pm, Sun 9am-1pm
5K Construction is a building company in Wolverhampton, based at 40A Oaklands Rd, WV3 0DS. We have more than 10 years of experience and over 500 completed projects across the city and the wider West Midlands. Every project starts with a site survey at your home and a written quote.
Wolverhampton has 31 conservation areas, and 13 of them carry Article 4 directions that remove some permitted development rights (City of Wolverhampton Council). If your home sits in one, the rules for windows, roofs and extensions can change. We survey your home, explain the approvals you need and help you through the application before work begins.

Read our reviews on GoogleAs local builders in Wolverhampton, we handle six types of work, each with one team and one point of contact from start to finish.
A loft is often the quickest way to add a bedroom or en-suite without losing garden. Our loft conversions cover rooflight, dormer, hip to gable and mansard designs. Outside a conservation area, a loft can be permitted development if the added roof space stays within 40 cubic metres on a terraced house or 50 cubic metres on other houses (Planning Portal). Inside one, such as Tettenhall Greens or Penn Fields, roof enlargements need planning permission.

Our house extensions include single storey, double storey, side return and wrap around designs. Without planning permission, a single storey rear extension can usually go 3 metres on a semi or terrace and 4 metres on a detached house (Planning Portal). In a conservation area, every side extension needs householder planning permission, which matters on corner plots in Park or Copthorne Road.

Opening a kitchen into a dining room often means removing a load-bearing wall and fitting steel beams designed by a structural engineer. Our kitchen installation team handles the structural alterations, plastering, flooring and fit-out as one job, so you are not juggling separate trades.

From a family bathroom refit in Wednesfield to a wet room for easier access, our bathroom installation work covers the full strip-out, plumbing, tiling and finishing. A new en-suite in a converted loft is planned with the loft itself, so pipe runs and drainage are agreed before the floor goes down.

Older homes around Chapel Ash, the Park area near West Park and Penn Fields often need more than a cosmetic update. Our renovation and refurbishment service covers structural repairs, re-plastering, new layouts and a full schedule of works for older homes.

Garage conversions in Wolverhampton are a popular way to add a study or playroom to a semi in Finchfield or Castlecroft. Our home improvements service also covers plastering and rendering, flooring, joinery, and painting and decorating.

Every job follows the same five stages, with one point of contact throughout. You can read more on how we work.
Most Wolverhampton homes were built in the 20th century, and many suit lofts and rear extensions well. An analysis of Valuation Office data counts 108,231 homes in the city: 27.6% built between the wars, 27.1% between 1945 and 1964, and 11.6% before 1919 (Skitts estate agents). The older homes cluster in the conservation areas, so the same project can need different approvals two streets apart.

If your home is in one of these 13 areas, even small changes such as new windows, a front porch or roof work may need planning permission. City of Wolverhampton Council lists 31 conservation areas, and these 13 carry Article 4 directions that remove some permitted development rights.
No match in this list. Your street may still be in one of the 31 conservation areas, so check with the council or ask us at your site survey.

How to check your address: use the council's Designated Heritage Assets map, which shows conservation areas, listed buildings and locally listed buildings. You can also call the council's Historic Environment Service on 01902 556026. Listed buildings need Listed Building Consent for internal and external changes, and there is no fee for that application. Historic England keeps the national list of listed buildings and handles requests to add new ones.
Often not, unless your home is in a conservation area, is listed or has had its permitted development rights removed. The table compares common projects.
| Project | Outside a conservation area | Inside a conservation area |
|---|---|---|
| Single storey rear extension | Up to 3 m (semi or terrace) or 4 m (detached) without planning permission; up to 6 m or 8 m through prior approval | Same 3 m or 4 m limits; the larger prior approval route is not available |
| Side extension | Single storey only, within set limits | Always needs householder planning permission |
| Rear extension over one storey | Within 3 m of the rear wall and 7 m from the rear boundary | Always needs householder planning permission |
| Loft conversion or dormer | Up to 40 cubic metres (terrace) or 50 cubic metres (other houses) | Roof enlargements need planning permission |

A householder planning application in England costs £548 from 1 April 2026 (Ribble Valley Borough Council fee table, based on the national regulations). If your project should be permitted development, a Lawful Development Certificate gives you written proof, which helps when you sell. Article 4 rules sit on top of these limits, so always check with the council first.
Almost every loft conversion, extension and structural alteration needs building regulations approval, even when planning permission does not. In Wolverhampton this sits with the Building Consultancy section of the council's Planning function, which runs one team of surveyors for the north and city centre and another for the south (City of Wolverhampton Council).
The regulations that most often apply are Part A (structure), Part B (fire safety), Part F (ventilation), Part L (energy), Part M (access) and Part P (electrical safety). The council warns that it may not issue a completion certificate if required inspections are missed. Building control can be reached on 01902 555595.
With so many semis and terraces in the city, most extensions and loft conversions touch a shared wall or dig near a neighbour's foundations. The Party Wall etc. Act 1996 sets the notice periods:
Work on an existing party wall, such as cutting in steel beams for a loft
Building a new wall on the boundary line
Digging foundations within 3 m (or 6 m in some cases) of a neighbour's building
Sources: GOV.UK Party Wall Act guidance; GOV.UK example notice letter. A notice stays valid for one year. Your neighbour can agree in writing to an earlier start.
Wolverhampton sits in the Black Country, where old coal workings can affect what lies under a garden. The Coal Authority (now the Mining Remediation Authority) has said the region's coalfield brings mining legacy risks that need checking early (World Coal).
For most home extensions, a full Coal Mining Risk Assessment is not required with a householder application (North Somerset Council). Ground conditions still matter for foundations. You can check your address on the GOV.UK coal mining information service, and a structural engineer can advise on foundation depth if old workings or made ground are found. You can also check Environment Agency long-term flood risk data for your address on GOV.UK.
If someone in your home is disabled, you may be able to get a Disabled Facilities Grant from City of Wolverhampton Council. The grant can pay towards changes such as a level access shower, a stairlift, wider doors or an extension for a downstairs bedroom (GOV.UK Disabled Facilities Grants). Apply through the council using the GOV.UK postcode finder before any work starts, as the council must assess and approve the work first.

What moves the price in Wolverhampton is usually the house itself: a hipped interwar roof, a conservation area finish, steel beams in a party wall or extra foundation depth. Ask any builder how their stage payments work and what the schedule of works includes before you sign.
Every project starts with a site survey at your home and a written quote.

Check the City of Wolverhampton Council Designated Heritage Assets map, which shows all 31 conservation areas, listed buildings and locally listed buildings. You can also call the council's Historic Environment Service on 01902 556026. 5K Construction also checks your address at the site survey before any design work starts.
An Article 4 direction removes some permitted development rights, so changes such as new windows, doors, porches or roof alterations on the front of a house may need planning permission. Thirteen Wolverhampton conservation areas have one, including Tettenhall Greens, Penn Fields and Park. Always confirm the exact rules with the council.
Usually not, if the house is outside a conservation area and the extra roof space stays within 40 cubic metres on a terrace or 50 cubic metres on other houses. In a conservation area such as Tettenhall Wood, roof enlargements need planning permission. 5K Construction confirms which route applies at your site survey.
Building control in Wolverhampton is run by the Building Consultancy section of City of Wolverhampton Council, with separate surveyor teams for the north and south of the city. You can also use a registered building control approver. Either way, you need a completion certificate once the work passes inspection.
Parts of the Black Country, including Wolverhampton, have a coal mining legacy. Most householder extensions do not need a full Coal Mining Risk Assessment, but you can check your address on the GOV.UK coal mining information service. A structural engineer can then advise on foundations if old workings are recorded nearby.
You may qualify for a Disabled Facilities Grant from City of Wolverhampton Council if someone in your home is disabled. It can help pay for changes such as a level access shower, stairlift or downstairs bedroom extension. Apply before any work starts, because the council must assess and approve the work first.
A householder planning application in England costs £548 from 1 April 2026, under the national fee regulations. That covers extensions and alterations to a single house. If your project is permitted development, a Lawful Development Certificate is a cheaper way to get written proof. Check the current fee with the council before applying.
5K Construction covers the whole city from our base at 40A Oaklands Rd, WV3 0DS. That includes Tettenhall, Penn, Finchfield, Compton, Castlecroft, Merridale, Wednesfield, Bushbury and Bilston. We also work in nearby towns such as Shrewsbury, Worcester and Stoke-on-Trent, with the same team and one point of contact.
Every project starts with a site survey at your home and a written quote. Call 07505 937668 or book through our contact page. At the survey we measure up, check the structure and confirm whether your street is in a conservation area, so the quote reflects your actual home.
