What through-lounge knock-throughs involve in Burgess Hill

We cover through-lounge knock-throughs in Burgess Hill (BN6, RH15) and the streets around it. It sits about 9.0 miles from Brighton, which we also cover. Each job is designed by a structural engineer and approved through local building control before work begins.

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

  • 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.
  • Period ceilings are often lath and plaster, which can crack or sag when the wall below is disturbed. Props are set to spread load gently, and damaged areas are repaired with lime plaster or overboarded, depending on the condition and your preference.
  • 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.
  • 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.
  • With the wall gone, the floorboards on each side may run in different directions or sit at slightly different heights. Matching reclaimed boards can be fitted across the old wall line, or the floor can be levelled for a new continuous finish.

How the job runs in Burgess Hill

  1. Look and measure

    We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.

  2. Design and price

    Calculations come back from the engineer and we confirm your fixed written price, line by line.

  3. 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.

  4. Fit, inspect, finish

    The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Building rules for Burgess Hill

Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.

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.

Through-lounge knock-throughs in Burgess Hill: your questions

How soon can through-lounge knock-throughs start in Burgess Hill?

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.

Who approves through-lounge knock-throughs in Burgess Hill?

Structural work in Burgess Hill 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.

Will the ceiling crack when the wall is removed?

Some minor cracking in old lath and plaster ceilings is possible, even with careful propping, because the structure is being disturbed. We prop to spread the load and protect ceilings where we can, and any cracks are filled or repaired as part of making good. Sound plaster normally stays intact.

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.

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.
