Looking for builders in Shrewsbury who understand both a timber-framed street inside the river loop and a family home in Meole Brace? Whether you want a loft bedroom in Copthorne, a kitchen extension in Belle Vue or a full renovation near Abbey Foregate, the right plan starts with the house, the street and how close you are to the River Severn.

As a building company in Shrewsbury and across the West Midlands, 5K Construction works from our base at 40A Oaklands Rd in Wolverhampton, to the east. 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.
Shrewsbury has 784 listed buildings, 15 of them Grade I (Shrewsbury Civic Society), and parts of the town flood when the Severn rises. Both shape what you can build. 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 Shrewsbury, we cover six types of work, each run by one team with one point of contact.
Victorian roofs in Belle Vue and Castlefields can hide enough headroom for a bedroom and en-suite. Our loft conversions include rooflight, dormer, hip to gable and mansard designs. Outside a conservation area, a loft can usually go ahead as permitted development within 40 cubic metres on a terrace or 50 cubic metres on other houses (Planning Portal). Inside the Shrewsbury or Belle Vue conservation areas, a dormer needs planning permission.

Our house extensions cover single storey, double storey, side return and wrap around designs. In Shrewsbury, two checks come first: is the house in a conservation area, and is the garden in a river flood zone? A householder 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).

Older terraces often have a narrow kitchen behind a separate dining room. Our kitchen installation team can take out the dividing wall with steel beams sized by a structural engineer, then handle the structural alterations, plastering, flooring and the full fit-out as one job.

Our bathroom installation service covers family bathrooms, en-suites and wet rooms. In a listed building, even moving a soil pipe or cutting a new vent through an old wall can need Listed Building Consent, so we plan the layout before anything is removed.

Older homes around Abbey Foregate, Coleham and Frankwell often need structural repairs, re-plastering and careful work around original features. Our renovation and refurbishment service brings this together in one schedule of works.

Garage conversions in Shrewsbury are a practical way to add a study or ground-floor bedroom to a family home in Meole Brace, Sutton Farm or Harlescott. Our home improvements service also covers plastering and rendering, flooring, joinery, and painting and decorating.

Every Shrewsbury job runs through five stages with one point of contact. Read more on how we work.
Shrewsbury's older homes sit in and around the river loop, while most 20th-century and newer housing spreads out beyond it. That split decides whether your project is mainly about heritage rules, flood risk or straightforward permitted development.

Yes, you can extend a home in a Shrewsbury flood zone, but the design has to show how it deals with flood water. The Severn regularly closes riverside roads: in February 2022 the Welsh Bridge gauge peaked at around 5.15 m, homes and businesses flooded, and Coton Hill, Smithfield Road and Coleham Head were among the roads closed (Shropshire Council newsroom).
| What to check | Why it matters | Where to check |
|---|---|---|
| Your flood zone | An extension in Flood Zone 2 or 3 that needs planning permission must include a flood risk assessment with finished floor levels | GOV.UK long-term flood risk |
| Floor levels | New floors are normally set no lower than existing floor levels | GOV.UK standing advice |
| Local defences | Frankwell has flood barriers and Coleham Head uses a demountable Environment Agency barrier | Shropshire Council newsroom |
| Flood warnings | Warnings are issued for the Severn at Frankwell, The Quarry and the Showground | Shropshire Council newsroom |
For homes near the river, flood resilience inside the extension matters as much as planning: tiled or resin floors, lime or water-resistant plaster, sockets set higher up the wall and a boiler kept off the ground floor.
If your home is listed, almost any change that affects its character needs Listed Building Consent, inside as well as out. Shrewsbury has 784 listed buildings, 15 of them Grade I, including Shrewsbury Castle and Shrewsbury Abbey (Shrewsbury Civic Society).
Historic England keeps the national list of listed buildings, which you can search online. Shropshire Council lists 17 conservation areas in central Shropshire, including Shrewsbury, Belle Vue and Harlescott. Article 4 directions also apply in these parts of town (Shropshire Council):
In these streets, changes such as replacement windows, doors or front roof work on unlisted houses may need planning permission. You can check boundaries on Shropshire Council's conservation area maps or contact its historic environment team before you plan.
Often not for a straightforward loft or rear extension 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). There is no fee for Listed Building Consent on its own. Shrewsbury Town Council is consulted on applications in the town and can comment on them, but Shropshire Council makes the decision. If your project is permitted development, a Lawful Development Certificate gives you written proof for when you sell.
Lofts, extensions and structural changes need building regulations approval even when planning permission does not. In Shrewsbury the local authority service is Shropshire Council Building Control, which offers Full Plans and Building Notice applications (Shropshire Council application form). You can also use a registered building control approver, listed on the Planning Portal approver search.
The parts 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).
In a listed building, building regulations and Listed Building Consent must be agreed together, because fire and energy upgrades can affect historic fabric.
Terraces in Castlefields and Belle Vue 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, Shropshire Council may help through a Disabled Facilities Grant, which can pay 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 Shrewsbury include heritage statements for listed homes, flood-resilient materials near the river and specialist joinery to match period windows. Ask any builder how their stage payments work and what the schedule of works covers.

Many homes inside the river loop, in Belle Vue and in streets such as Castlefields and Mountfields sit in a conservation area. Check Shropshire Council's conservation area maps or ask its historic environment team. 5K Construction also checks your address at the site survey, before any design work starts on your project.
Yes, if the house is listed and the work affects its character, inside or outside. Shrewsbury has 784 listed buildings, so this is common in the town centre. There is no application fee for Listed Building Consent, but drawings and heritage details are needed. Working without consent is a criminal offence.
Usually yes, but an extension in Flood Zone 2 or 3 that needs planning permission must include a flood risk assessment showing finished floor levels. Streets near the Severn such as Frankwell, Coleham and Coton Hill need extra care. 5K Construction checks the flood map for your address at the site survey.
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 the Shrewsbury or Belle Vue conservation areas, a dormer or other roof enlargement needs planning permission from Shropshire Council.
Shropshire Council lists Article 4 directions for certain properties in Belle Vue and for Cherry Orchard, Mountfields, New Street, The Mount, St Julians Friars and Castlefields. In these streets, changes such as new windows, doors or front roof work may need planning permission. Always confirm the exact rules with Shropshire Council first.
Shropshire Council Building Control is the local authority service for Shrewsbury, and it accepts Full Plans and Building Notice applications. You can also use a registered building control approver instead. Either way, you need a completion certificate once the work passes its final inspection, so keep it safe for when you sell.
A householder planning application in England costs £548 from 1 April 2026, under the national fee regulations, and Shropshire Council charges that fee for extensions and alterations to a single house. Listed Building Consent on its own has no fee. Check the current fee with the council before applying, as fees can change.
5K Construction covers Shrewsbury and the surrounding area, including the town centre, Castlefields, Harlescott, Abbey Foregate, Monkmoor, Sutton Farm, Frankwell, Copthorne, Kingsland, Belle Vue, Coleham, Meole Brace and Bayston Hill.
