Opening up a New Barnet terrace usually means one of two moves: through the wall between the front and rear reception rooms, or through the back wall into a side return infill. Both are structural, both need a beam sized by an engineer, and both change how the house heats and sounds. We do the structure and the finish as one job.
The two knock throughs that suit an EN4 terrace
The through lounge is the classic New Barnet alteration, taking the wall between the two reception rooms out so light from the bay reaches the back of the house. It works, but be honest about the trade off before you commit: you lose the only quiet room, the hall noise carries, and the pair of chimney breasts either side of that wall usually have to go too, which is a separate structural exercise. Plenty of owners in EN4 do it and never look back. A few wish they had kept a door.
The second move suits the rear better. A Victorian terrace has a back addition with a narrow strip of land beside it, and infilling that side return widens the rear of the house by two metres or so, turning a corridor kitchen into a room. The wall between the old kitchen and the new infill comes out on a beam. Watch the floor levels: the back addition often sits a step below the main house, and the level has to be resolved in the screed rather than with a threshold strip.
Structure, services and consents across New Barnet
The steel is sized by a structural engineer we appoint, bears on padstones cut into sound masonry, and goes in behind full propping with the wall taken down in stages. Barnet Council building control inspects the beam and the bearings before they are covered and issues the completion certificate. Where the beam bears into a party wall, and in a terrace it usually does at one end at least, the work is notifiable under the Party Wall etc. Act 1996 and the notice is served by you before we start.
Services are what people forget. The wall coming out held the radiator, the light switches and often the hall lighting circuit, and a single larger room needs its heating output recalculated rather than assumed. Open plan also changes escape and fire separation if the stair now opens into the same volume, which matters in a New Barnet terrace where the stair rises straight out of the front room. We raise that with building control at plan stage instead of discovering it at the final inspection.
