About our through-lounge knock-throughs service in Epsom
We carry out through-lounge knock-throughs in Epsom, covering the KT17, KT18, KT19, KT21 and SM7 postcode districts. It sits about 12.5 miles from Woking, which we also cover. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
We plan the steel so the opening suits the room's proportions and keeps period features where you want them, from chimney breasts to cornicing. The survey visit, calculations from a qualified structural engineer, building control, party wall notices through a party wall surveyor where needed, propping, steel and making good are all set out in one itemised written quote.
Key points for your project
- Many owners leave short nibs of wall at each end of the opening rather than going fully wall to wall. Nibs can give the beam a bearing, line up with the chimney breasts and keep the feel of two linked rooms, but the engineer decides whether they are adequate.
- Ornate cornicing often runs around both rooms and stops at the wall being removed. Where practical, the run is extended across the opening by matching the profile, either run in place or cast, so the joined room looks original rather than patched.
- Radiators, pipe runs and sockets on the dividing wall need relocating. Older houses sometimes have heating pipes running under the floor along the wall line, so these are traced and moved by a heating engineer before the wall comes down.
- Chimney breasts on the party wall in each room often sit close to the dividing wall. The beam may need to bear near them or avoid them, so the engineer checks how the breasts and flues relate to the new bearing before the opening width is fixed.
- The structural stage for a through-lounge typically takes three to five working days. Both reception rooms are out of use for that time, so furniture is moved out or stacked and sheeted, and the hallway is kept clear as the main walkway.
Four stages, one team
Survey in Epsom
We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.
Engineer's design
A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.
Building control
We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Approvals in Epsom
For Epsom, building control is provided by the local council's building control team, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.
If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Local questions answered
Can you work on older or listed homes in Epsom?
Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
Who approves through-lounge knock-throughs in Epsom?
Structural work in Epsom needs a building notice or full plans application to the local council's building control team or a registered building control approver. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
Is the wall between two reception rooms load-bearing?
In most period terraces and semis it is, because it carries the floor joists and the wall between the bedrooms above. Some later houses have lighter partitions in this position, so the only way to be sure is an engineer's inspection. We arrange this during the survey and design stage.
Can I knock my front and back rooms into one?
Yes, in most houses. The dividing wall is usually load-bearing, so a structural engineer designs a steel beam to carry the floor and wall above, and building control approves the work. In terraces and semis the beam often bears into the party wall, which in England and Wales means serving a party wall notice before work starts.
Should I keep the chimney breasts when knocking through?
Most people do, because the breasts frame the opening and support the stack above. Removing a chimney breast is a separate structural job needing its own design and approval, and it affects your neighbour if the stack is shared. Keeping them usually simplifies the steelwork and preserves the character of the room.
