Opening up a Hadley Wood house is a different exercise from opening up a semi. The rooms are already large, the halls are wide, and many of these villas are three storeys, which brings Approved Document B and the protected staircase into the conversation as soon as the hall wall is on the drawing.
Open-plan ground floors in Hadley Wood villas
The usual scheme runs the kitchen, dining and garden room together across the back of the house, with a wide opening through to the front reception. On a plot this size the finished space can be seven or eight metres deep, which means either one long beam or a pair of beams with a column, and columns need thinking about early because a steel post landing in the middle of a kitchen island is a decision, not an accident. The engineer sizes it; we build to it.
Not every wall should go. In an Edwardian villa the hall and the staircase are the best part of the plan, and stripping the hall into the reception rooms usually makes the house feel smaller rather than larger. Broken plan works better here: a wide cased opening, a glazed screen in a steel frame, or a half height run of joinery that keeps the hall reading as a hall. It also keeps the stair enclosed, which the fire strategy on a three storey house will thank you for.
Fire strategy and building control in EN4
This is the part that catches people out. Approved Document B treats a house of three or more storeys differently, and once you open the ground floor into the stair enclosure the protected escape route has gone. The workable route is usually a domestic sprinkler system to BS 9251 with interlinked detection throughout, or keeping the stair enclosed and settling for a wide opening instead. Barnet building control will want the strategy agreed at application stage, not discovered when the plasterboard is already going up.
The rest is conventional but bigger. Long spans need packing and levelling carefully so the floor above does not develop a line across the ceiling; deflection limits on a beam carrying brittle plaster are tighter than the strength check alone. Services that ran in the removed wall have to be rerouted, and in a room this size the heating rarely copes on the original radiators, so the emitter sizing gets rechecked. Inspections happen while the steel and its bearings are still open to view, before anything is boarded.
