What through-lounge knock-throughs involve in Gillingham

For homes in Gillingham and the ME1, ME2, ME3, ME4 and ME5 districts, we handle through-lounge knock-throughs from survey to sign-off. Our coverage runs across Kent, so nearby villages are included too. The beam is sized by a structural engineer and inspected before it is boxed in.

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.

Things to plan for

  • 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.
  • Minor hairline cracks can appear in plaster upstairs as the structure takes up the new support. This is common after a knock-through and is usually filled at decoration stage, but wider or growing cracks should be reported so they can be checked.
  • The width of the opening, whether the beam bears into a party wall, and how much period detail has to be restored all affect the price. Lath and plaster repairs, cornice matching and floorboard work are priced as separate lines in the quote.
  • 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.
  • If the house is listed, internal structural alterations need listed building consent as well as building regulations approval. Conservation area status does not usually affect internal work, but flats within converted period houses normally need the freeholder's consent.

What happens, step by step

  1. Survey in Gillingham

    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.

  2. 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.

  3. Building control

    We submit a building notice or full plans application to Medway Council, so approval is in place before the wall is touched.

  4. 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.

Building rules for Gillingham

For Gillingham, building control is provided by Medway Council, 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.

Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Questions about through-lounge knock-throughs in Gillingham

What happens at the survey visit in Gillingham?

We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.

How soon can through-lounge knock-throughs start in Gillingham?

Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.

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.

How wide can a through-lounge opening be?

That depends on what the wall carries and how the beam ends can be supported, and the structural engineer sets it. Many owners go nearly full width, keeping short nibs at each end, while others choose a narrower opening to keep two distinct rooms. Wider spans need heavier steel and sometimes columns.

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.

Can you work on older or listed homes in Gillingham?

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.
