GS Renovation removes load-bearing walls across Mill Hill, in the substantial detached houses up around The Ridgeway and in the interwar semis on the streets running down to Mill Hill Broadway. With more than 30 years of hands on structural experience in NW7, we prop properly, install engineer sized steel and hand the job over signed off by Barnet building control.
Spine walls in Mill Hill's detached and interwar houses
A detached Mill Hill house gives you a wider frontage than the interwar semis nearer the Broadway, and that width is the first thing a structural engineer looks at. The wall between the two reception rooms is normally carrying the first floor joists, and under a cut roof it often carries struts holding the purlins up as well. Open seven or eight metres of it and the beam gets deep, because depth follows span. Owners are frequently surprised by the section size, and that surprise is better had at design stage than on delivery day.
So we start with the engineer's assessment rather than with a bolster. Temporary props go in off proper sole plates, the masonry comes down in courses instead of one push, and the steel is lifted onto padstones bedded on sound brickwork before any prop is struck. In the older village houses along The Ridgeway the mortar is often lime rather than cement, which spreads load differently, so the engineer may call for a longer bearing or a spreader plate. We check what we are bearing onto before cutting the pocket.
Barnet building control and party walls in NW7
Removing a load-bearing wall inside a Mill Hill house is controlled by the Building Regulations, not by planning permission. Barnet Council's building control, or an approved inspector, reviews the engineer's calculations, inspects the beam and its bearings while they are still open, and issues the completion certificate your buyer's solicitor will ask for. Owners inside the Mill Hill Village conservation area often assume the designation reaches indoors. It does not. Conservation area control is about the outside of the building; the interior is only protected where the house is listed.
Party wall duties depend on the house rather than the postcode. In a detached Mill Hill property with no shared wall, an internal beam usually triggers nothing under the Party Wall etc. Act 1996, and we say so rather than manufacture paperwork nobody needs. In the paired interwar houses closer to Mill Hill Broadway the beam frequently bears into the wall shared with next door, which is notifiable. We prepare the notice and explain the timing, but you serve it as building owner, because that duty sits with you and not with your contractor.
