Wall removal is taking out an internal wall to open up rooms; where the wall is load-bearing, a steel beam sized by a structural engineer is installed on padstones to carry the weight above, with the work approved by building control.
Whatever prompted you to look into removing a wall, whether wear and tear, a growing family or plans to move, we can survey your Portsmouth home and give you a price in writing. Homes in the South East typically come in at £3,400–£9,000, VAT included, for this kind of work. We also cover Southsea, Gosport and Fareham, and the same steps apply wherever you are in Hampshire.

Local housing and removing a wall
Southampton and Portsmouth have dense Victorian terraces, with plenty of post-war rebuilding after wartime bombing. Winchester keeps Georgian and medieval streets, Basingstoke expanded rapidly with 1960s and 1970s estates, and New Forest villages feature cob, thatch and brick. Brick and flint is common on the chalk downs, and new estates ring most towns.
Terraces suit loft rooms and side-return extensions; post-war and expanded-town homes often need window, roofline and cladding renewal. Cottages in the Forest may call for lime repairs and planning-sensitive windows.
These patterns matter for removing a wall: older walls, roofs and floors in Portsmouth can need different materials or extra preparation compared with newer homes.
Do you need permission in Portsmouth?
As Portsmouth is in England, read the following with that system of planning and building control in mind. We check what applies to your house with the council before you receive a quote.
Removing an internal wall does not need planning permission in England unless the house is listed.
If the wall is load-bearing, Building Regulations approval is needed, with a structural engineer’s calculations for the steel beam and padstones. Where the beam bears on a shared wall, the Party Wall etc. Act 1996 applies.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
From survey to handover
Free site survey
First, someone visits your home in Portsmouth to see the space, take measurements and note anything that could affect the work, such as access or the condition of what is there. There is no charge for this visit.
Your fixed price
You get the price in writing, itemised so you can see where the money goes. As long as the specification stays the same, that is the price you pay for removing a wall.
Dates and permissions
Once you accept, we agree start dates, order materials and deal with any planning, building control or neighbour notices the job needs. You'll know who is coming and when before work begins.
On site to finish
On site, the agreed plan is followed and any change is put in writing first. At completion we do a final clean, go through the snagging list with you and leave you with the relevant documents.
How we work
Frequently asked questions
How long will removing a wall take?
On a typical home, allow 1–3 weeks including making good. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
Do I need building regulations approval to remove a wall?
Removing a load-bearing wall needs building regulations approval anywhere in the UK, and in Scotland a building warrant. A structural engineer calculates the beam and supports, and building control inspects the work. Removing a non-structural wall may still need approval if it affects fire escape routes, such as opening a hallway into a living room. We handle the applications and inspections.
What is a steel beam and why is it needed?
A steel beam, often called an RSJ, is a strong steel section installed where a load-bearing wall used to be, so the weight above is carried across the opening to the walls at each end. It sits on padstones that spread the load. The size depends on the span and the load, which a structural engineer calculates. The beam is then boxed in or plastered.
Can I have a beam that does not show?
A flush or hidden beam sits within the depth of the ceiling so there is no visible downstand, giving a clean, open look. It is possible where the floor joists can be connected into the side of the beam, which takes more steel and labour. It costs more than a standard beam below the ceiling. The engineer confirms whether it suits your house.
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
