As a building company in Droitwich Spa and across the West Midlands, 5K Construction works from our base at 40A Oaklands Rd in Wolverhampton, to the north. We have more than 10 years of experience and over 500 completed projects. Every project starts with a site survey at your home and a written quote.
Droitwich is built on salt. Wychavon District Council notes that buildings on the High Street lean at odd angles because of subsidence after brine extraction (Wychavon District Council), so the ground matters as much as the design. 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 Droitwich Spa, we cover six types of work, each run by one team with one point of contact.
Many family homes in Droitwich have room in the roof for a bedroom and en-suite. Our loft conversions include rooflight, dormer, hip to gable and mansard designs. Outside a conservation area, a loft is usually permitted development within 40 cubic metres on a terrace or 50 cubic metres on other houses (Planning Portal). In the Droitwich Spa conservation area, a roof enlargement needs planning permission.

Our house extensions cover single storey, double storey, side return and wrap around designs. On most semis, a single storey rear extension of up to 3 metres can go ahead without planning permission, or 4 metres on a detached house (Planning Portal). In the old part of town, where the ground has moved in the past, a structural engineer should check the foundation design before it is fixed.

Opening a kitchen into the dining room is a popular way to create a larger family space. Our kitchen installation team handles the structural alterations, steel beams sized by a structural engineer, plastering, flooring and the full fit-out as one job.

Our bathroom installation service covers family bathrooms, en-suites and wet rooms. A new en-suite in a loft is planned with the loft itself, so drainage runs and ventilation are agreed before the floor goes down.

Older buildings in the town centre, some of them out of level after past subsidence, need repairs that work with the existing structure rather than against it. Our renovation and refurbishment service brings structural repairs, re-plastering and new layouts together in one schedule of works.

Garage conversions in Droitwich Spa are a practical way to add a study or playroom to a family home. Our home improvements service also covers plastering and rendering, flooring, joinery, and painting and decorating.
Learn moreIn Droitwich Spa, the same plan can need different approvals and foundations depending on whether your house is in the old salt area, the conservation area or near the River Salwarpe. Tell us what you want and we will check the house first.
Every Droitwich Spa job runs through five stages with one point of contact and full project management. Read more on how we work.
Droitwich grew in two very different ways. The old town grew up around the brine springs along the River Salwarpe, while later growth spread to higher ground south towards Witton and west towards the railway station, outside the salt area where subsidence had been felt (Victoria County History, via British History Online). Later, the spa years brought planned residential streets near the centre (Wychavon District Council conservation area appraisal).

In the 19th century Droitwich became the only salt-water spa town in Britain, and its brine is the strongest natural saltwater known, at about 30% natural salts (Wychavon District Council). Pumping that brine changed the ground under the old town.
| What happened | What it means today | Source |
|---|---|---|
| Brine extraction caused subsidence, and High Street buildings now lean at odd angles | Older buildings in the old town may be out of level | Wychavon District Council |
| The salt area was clearly defined, and later growth moved to higher ground outside it | Homes outside the old salt area have a different ground history | Victoria County History |
| A brine pump in Gurney's Lane worked from 1850 until 1921; Tower Hill Brine Pump is the only operational well left | Reminders of the salt industry still stand around the town | Wychavon District Council |
For an extension or structural alteration in the old town, ask a structural engineer to assess the ground and the existing building before the design is fixed. Homes near the River Salwarpe should also check flood risk: an extension in Flood Zone 2 or 3 that needs planning permission must include a flood risk assessment showing finished floor levels (GOV.UK standing advice). You can check your address against Environment Agency data on GOV.UK.
The Droitwich Spa conservation area focuses on the surviving historic areas of the town centre and nearby residential areas, including planned areas linked to the town's development as a spa resort (Wychavon District Council).
| Your home | What it means | What you need |
|---|---|---|
| Listed building | Almost any change that affects its character, inside or out | Listed Building Consent (no application fee) |
| In the conservation area, not listed | Fewer permitted development rights: side extensions, rear extensions over one storey and roof enlargements need planning permission | Householder planning permission for those works |
| Outside the conservation area | Normal permitted development rules apply, unless a planning condition has removed them | Check the limits below; a Lawful Development Certificate gives written proof |
Historic England keeps the national list of listed buildings, and you can search it online by address.
Often not for a loft or rear extension on a house outside the conservation area. Inside it, or on a listed house, the answer is usually yes.
| Project | Outside a conservation area | Inside a conservation area |
|---|---|---|
| Single storey rear extension | Up to 3 m (semi or terrace) or 4 m (detached); up to 6 m or 8 m through prior approval | 3 m or 4 m limits only, no prior approval route |
| Side extension | Single storey, within set limits | Needs householder planning permission |
| Two storey rear extension | Within 3 m of the rear wall and 7 m from the rear boundary | 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). Planning applications in Droitwich Spa go to Wychavon District Council. If your project is permitted development, a Lawful Development Certificate gives you written proof for when you sell.
Building regulations approval is needed for almost every loft conversion, extension and structural alteration, even when planning permission is not. In Droitwich Spa the local authority service is South Worcestershire Building Control, a partnership of Malvern Hills District Council, Worcester City Council and Wychavon District Council (Worcester City Council). You can also use a registered building control approver from the Planning Portal approver search.
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).
Keep the completion certificate safe, because buyers' solicitors will ask for it.
Terraced and semi-detached homes share walls, so most lofts and rear extensions on them involve the Party Wall etc. Act 1996.
Work on an existing party wall, such as inserting steel beams
A new wall on the boundary line
Foundations within 3 m (or 6 m in some cases) of a neighbour's building

If someone in your home is disabled, you may be able to get a Disabled Facilities Grant towards changes such as a level access shower, stairlift or downstairs bedroom extension (GOV.UK). Apply through the GOV.UK council finder before any work starts.

Extra costs that are more common in Droitwich include a structural engineer's ground and foundation assessment in the old salt area, heritage statements in the conservation area, and a flood risk assessment for homes near the River Salwarpe. Ask any builder how their stage payments work and what the schedule of works covers.

Parts of the old town are. Wychavon District Council notes that buildings on the High Street lean at odd angles because of subsidence after brine extraction. Later growth moved to higher ground outside the salt area, so the ground history depends on where your home is. A structural engineer can advise before you design.
If it is in the historic town centre or nearby spa-era streets, it may be. The Droitwich Spa conservation area covers those areas, including planned streets linked to the spa resort. 5K Construction checks your address at the site survey, before any design work starts, so you know which rules apply.
Not usually, if the house is outside the conservation area and the extra roof space stays within 40 cubic metres on a terrace or 50 cubic metres on other houses. In the conservation area, a dormer or other roof enlargement needs planning permission from Wychavon District Council, and listed homes also need Listed Building Consent.
South Worcestershire Building Control is the local authority service for Droitwich Spa. It is a partnership of Malvern Hills District Council, Worcester City Council and Wychavon District Council. You can also use a registered building control approver. Either way, keep the completion certificate safe, because buyers' solicitors will ask for it.
Usually yes, but if your garden is in Flood Zone 2 or 3 and the extension needs planning permission, the application must include a flood risk assessment showing finished floor levels. You can check your address on GOV.UK. 5K Construction checks the flood map for riverside homes at the site survey.
Yes, if your home is listed and the work affects its character, inside or outside. There is no application fee for Listed Building Consent, but drawings and heritage details are needed. In the old town, a structural engineer's assessment of past ground movement is also worth having before any alterations.
A householder planning application in England costs £548 from 1 April 2026, under the national fee regulations, and that covers extensions and alterations to a single house. Listed Building Consent on its own has no fee. If your project is permitted development, a Lawful Development Certificate gives written proof for when you sell.
