Structural Alterations & Wall Removal in Brighton & Hove
Removing a wall to open up a space is one of the most rewarding changes you can make to a home, but it is also one of the most serious. Get it wrong and you risk cracked ceilings, sagging floors or a structure that is quietly overloaded. In Brighton and Hove's Victorian and Edwardian terraces, load paths are rarely obvious, so every alteration should start with a structural engineer's calculations and proper Building Regulations approval — not a guess and a sledgehammer.
When This Service Is Needed
- You want to knock two rooms into one open-plan space.
- A load-bearing wall or chimney breast needs removing.
- A doorway or opening needs widening or repositioning.
- A structural crack or sagging floor suggests the structure is moving.
- You are converting a loft, garage or extension that changes the load path.
- A previous alteration was done badly and needs correcting.
Brighton & Hove Property Context
Many Brighton and Hove homes are Victorian or Edwardian terraces with solid brick walls, timber floors and chimney breasts that were central to how the house was built. Over the years, walls have often been altered, chimneys part-removed and rooms reconfigured — sometimes without proper support. The coastal setting adds its own issues: older mortar can be soft, some properties have movement in the ground beneath them, and hidden damp can weaken bearings. In flats and leasehold properties, structural work usually needs freeholder consent, and party wall matters can apply where a shared wall is affected. All of this means the structure needs to be understood properly before anything is opened up.
Materials & Approach
| Area | Recommended Approach |
|---|---|
| Load-bearing walls | Steel beam (RSJ) or timber beam sized by a structural engineer |
| Beam supports | Padstones or spreader plates onto adequate bearings |
| Temporary works | Acrow props and strongboys during the opening-up |
| Chimney breasts | Gallows brackets or beam support for the stack above |
| Making good | Boxing-in, plastering and floor repair around the new beam |
How We Approach the Work
- 01Inspect the structure and identify which walls are load-bearing.
- 02Arrange a structural engineer to survey and produce calculations.
- 03Submit for Building Regulations approval before any work starts.
- 04Set up temporary supports to hold the structure safely.
- 05Open up carefully and install the specified beam onto proper bearings.
- 06Fit padstones, connections and any restraint the design requires.
- 07Remove temporary works only once the beam is fully supporting the load.
- 08Make good the openings, floors and finishes, then arrange sign-off.
Common Mistakes
The most serious mistake is removing a wall without confirming whether it is load-bearing and without an engineer's calculations. A wall may look like a simple partition but still carry the floor or roof above. Taking it out and hoping for the best can lead to cracking, sagging and, in the worst cases, collapse.
Another common mistake is fitting the beam without proper bearings or padstones. A beam is only as good as what it sits on. If the ends crush into soft brickwork, or the supports below are not adequate, the load simply transfers the problem somewhere else rather than solving it.
Building Regulations
Removing a load-bearing wall, altering a chimney breast or changing the structure of a home requires Building Regulations approval, and the work must be signed off by Building Control. A structural engineer produces the calculations that specify the beam size and support details. If electrics are affected, that work falls under Part P and must be carried out and certified correctly. Structural alterations that form part of a loft conversion, extension or garage conversion also need Building Regulations approval, and some may need planning permission — particularly in conservation areas or on listed buildings, which Brighton and Hove has many of. Where a shared wall between properties is affected, the Party Wall etc. Act 1996 may require notice to be served on neighbours before work starts.
Cost Factors
- Whether the wall is load-bearing or a simple stud partition.
- The size and specification of the steel or timber beam required.
- Structural engineer fees and Building Control fees.
- The length of the opening being created.
- What sits above the wall — another floor, roof or chimney stack.
- Access and how much temporary propping is needed.
- Services in the wall, such as pipes, cables or a soil pipe.
- Making good, boxing-in, plastering and floor repairs afterwards.
