Renovations in St John's Wood

St John's Wood was laid out as villas with gardens rather than as continuous terraces, and that early decision still gives NW8 a housing stock unlike anywhere else this close to central London. Detached and semi detached houses with real garden depth sit alongside substantial red brick mansion blocks, particularly on the roads between the High Street and Regent's Park. Renovation work divides along the same line: houses where space at the back makes reconfiguration realistic, and flats where the envelope is fixed and the lease governs what happens inside it.

Villas with gardens, and what that allows

Having a garden and often a side access changes a renovation completely. Materials can be stored on site, a skip can sit off the street, and muck and steel never have to travel through the hall. That alone shortens a programme against a comparable job in a terrace with one front door. The work itself in these houses tends to be a full reconfiguration of the ground floor, because the original plan puts the kitchen in the smallest, darkest room and wastes the best light at the back on a scullery and a passage.

These are substantial buildings, though, and the structure deserves respect. Roofs are often complex with valleys and hips, floor joists span long distances and have been notched by generations of plumbers, and a new opening across the rear wall usually carries more than the owner expects. The beam over it is designed by an independent structural engineer we bring in, and our job is to install exactly what that design calls for, propping until load has transferred and leaving bearings open for inspection. On a semi detached house, bearings in the shared wall bring party wall duties with them.

Red brick mansion blocks off the High Street

Flats in the mansion blocks around Abbey Road and the High Street are a different discipline. They are leasehold, so the freeholder or managing agent issues a licence to alter before structural or layout work begins, and the application usually calls for drawings, a specification, a structural engineer's report and the contractor's insurance details. Permitted development rights do not extend to flats. Blocks of this type also set working hours, control lift use and expect communal areas protected before a single bag comes through the door. Allow real time for that process before any start date is agreed.

Inside, the original plan is generous but dated: a long corridor, a small kitchen at the back, and bathrooms that were added rather than designed in. Replanning is worthwhile and usually possible, but only once the engineer has established which walls are brick and structural and which are later partitions. Acoustic performance matters far more than it does in a house, because there are homes directly above and below. Lease clauses about floor coverings exist for a reason, and we build to them rather than around them. Sound insulation in a new floor build-up is worth specifying properly rather than treating as an afterthought.
