Extensions and knock-throughs in Upper Norwood & SE London

A knock-through can change how a home feels, but the right plan depends on the layout, walls and services already in place. Nova Coat can discuss suitable small opening-up and finishing work, then explain what needs to happen before plastering begins.

Where an opening needs structural alteration, the structural work must be designed and carried out with a structural engineer, with Building Control sign-off where required. Nova Coat handles plastering and making good once that work is complete.

Extension work often leaves new junctions where old walls meet new plasterboard, reveals around openings and surfaces that need a consistent finish. These details are checked on site so the finish can be planned around the actual substrate and the work already completed.

If the extension includes structural changes, those are dealt with through the appropriate engineer and Building Control process. This page is about suitable building work and the plastering and finishing around it, not a substitute for structural design.

Once beams, lintels or other structural elements have been installed and checked, the surrounding surfaces may need boarding, beads, plastering or careful patch repairs. Making good can help connect the new opening with the adjoining walls and ceiling.
