Looking for builders in Worcester who know the difference between a Regency villa off Britannia Square and a newer semi in Warndon Villages? Whether you want a loft bedroom in Barbourne, a kitchen extension in St John's or a full renovation in Battenhall, the right plan starts with the house and the rules on your street.
Open Mon-Fri 8am-6pm, Sat 8am-2pm, Sun 9am-1pm
As a building company in Worcester 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.
Two Worcester rules catch homeowners out. Since 1 July 2014, turning a family house into a small shared house needs planning permission anywhere in the city, and several conservation areas north of the centre carry Article 4 directions (Worcester City Council). 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 Worcester, we cover six types of work, each run by one team with one point of contact.
Victorian and Edwardian roofs in Barbourne can have room 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). Inside one, such as Britannia Square or Park Avenue, roof enlargements need planning permission.

Our house extensions cover single storey, double storey, side return and wrap around designs. On most Worcester 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). Larger designs, and any side extension in a conservation area, need an application to Worcester City Council.

Knocking a kitchen through to the dining room is one of the most common jobs in Worcester's older terraces. 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.

Period homes in St John's, Barbourne and around Britannia Square often need structural repairs, new layouts and careful work around original windows and fireplaces. Our renovation and refurbishment service brings this together in one schedule of works.

Garage conversions in Worcester are a practical way to add a study or playroom to a semi in Warndon Villages, St Peter's or Lower Wick. Our home improvements service also covers plastering and rendering, flooring, joinery, and painting and decorating.

In Worcester, the same plan can need different approvals depending on whether your street is in a conservation area. Tell us what you want and we will check the house first.
Every Worcester job runs through five stages with one point of contact and full project management. Read more on how we work.
Worcester's oldest housing sits in conservation areas just north and west of the centre, while most of the city's 20th-century and newer homes spread out to the east. That split decides whether your project is mostly about heritage rules or straightforward permitted development.
| Area | Typical homes | What usually suits them | Main check |
|---|---|---|---|
| Britannia Square and York Place (WR1) | Regency stucco villas, historic terraces on York Place and back lanes behind them | Careful renovation, internal reconfiguration, rear rooms | Conservation area since 1969; York Place has an Article 4 direction; many houses are Grade II listed |
| Barbourne and Park Avenue (WR1, WR3) | Victorian and Edwardian houses with original windows, doors and decorative surrounds | Loft conversions, rear kitchen extensions, period refurbishment | Park Avenue conservation area and Article 4 direction |
| Shrubbery Avenue (WR1) | Older houses in a small conservation area | Rear extensions and lofts designed to match the street | Article 4 direction in force since 20 December 2018 |
| St John's (WR2) | A historic district west of the River Severn | Renovation, kitchen and bathroom upgrades, rear extensions | Conservation area since 1969; check the flood map near the river |
| Battenhall, St Peter's, Lower Wick, Dines Green | Mostly 20th-century suburbs | Hip to gable and dormer lofts, single storey extensions | Usually permitted development |
| Warndon Villages and Ronkswood (WR4, WR5) | Newer estates | Garage conversions, single storey extensions, kitchen refits | Check for planning conditions on newer estates |

Worcester has two kinds of Article 4 direction, and both can catch homeowners out. One covers the whole city and controls shared houses; the others cover specific conservation areas and control small external changes.
| Direction | Where it applies | What it means for you | In force since |
|---|---|---|---|
| Houses in Multiple Occupation | Every ward in Worcester | Changing a family house into a small shared house for three to six unrelated people needs planning permission | 1 July 2014 |
| York Place | Britannia Square conservation area | Some minor external changes that are normally permitted development need planning permission | 1986 |
| Shrubbery Avenue | Shrubbery Avenue conservation area | Some minor external changes need planning permission | 20 December 2018 |
| Park Avenue | Park Avenue conservation area, Barbourne | Made by the council on 22 June 2020 to control minor development | 22 June 2020 (made for confirmation) |

If you are converting a house to let as a shared house, or extending one, check the council's Houses in Multiple Occupation guidance first. Turning a small shared house back into a family home remains permitted.
Worcester City Council designated its first conservation area, The Historic City, in 1969 and has added 18 more since (Worcester Civic Society). Britannia Square and St John's were both designated in 1969 (planning.data.gov.uk).
In a conservation area you have fewer permitted development rights: side extensions, rear extensions over one storey and roof enlargements all need planning permission. If your home is listed, almost any change that affects its character needs Listed Building Consent, inside as well as out, and there is no fee for that application. Historic England keeps the national list of listed buildings, and you can search it online. Worcester City Council's heritage pages include a check for whether your property is listed.
Often not for a loft or rear extension on a house outside a conservation area. Inside one, 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). If your project is permitted development, a Lawful Development Certificate gives you written proof for when you sell, and Worcester City Council accepts these applications.
Building regulations approval is needed for almost every loft conversion, extension and structural alteration, even when planning permission is not. In Worcester 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.
Homes close to the Severn should check flood risk before designing an extension. 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.
Terraces in Barbourne, York Place and St John's share walls on both sides, so most lofts and rear extensions there 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
Sources: GOV.UK Party Wall Act guidance; GOV.UK example notice letter. Notices stay valid for one year.
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 Worcester include heritage statements for listed homes and specialist joinery to match period windows in conservation areas. Ask any builder how their stage payments work and what the schedule of works covers.

Whether you need a builder in Worcester for one room or a whole house, one team and one point of contact look after it from start to finish.

Many homes north and west of the centre are, including Britannia Square, Barbourne's Park Avenue, Shrubbery Avenue and St John's. Worcester City Council's heritage pages show conservation area boundaries and whether a property is listed. 5K Construction also checks your address at the site survey, before any design work starts on your project.
Yes. Since 1 July 2014 an Article 4 direction across every Worcester ward means changing a family house into a small shared house for three to six unrelated people needs planning permission. Turning a shared house back into a family home is still permitted. Check the council's guidance before you buy or convert.
Worcester City Council lists Article 4 directions for York Place in the Britannia Square conservation area, for the Shrubbery Avenue conservation area, and a direction made in 2020 for Park Avenue in Barbourne. In these streets, some minor external changes need planning permission. Always confirm the exact rules with the council first.
Not usually, 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 Britannia Square or Park Avenue, a dormer or other roof enlargement needs planning permission from Worcester City Council.
South Worcestershire Building Control is the local authority service for Worcester. 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.
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.
5K Construction covers the whole city, including the city centre, Britannia Square, Barbourne, Arboretum, Claines, Northwick, St John's, Dines Green, Lower Wick, Battenhall, St Peter's, Ronkswood and Warndon Villages.

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 check the structure, the conservation area and listing status and any Article 4 rules, so your quote reflects the real house and the real approvals.
