Structural Alterations in Chiswick
Knock-throughs, load-bearing removals, chimney breast removal and full internal reconfiguration — including reconfiguring houses into multiple units.
Removing a load-bearing wall means a beam sized by a structural engineer, padstones that can take the load, and temporary propping while it goes in. Chimney breast removals need the stack above supported with gallows brackets or a beam. All of it is notifiable to building control. We have reconfigured houses extensively, including converting a three-bedroom property into a six-bedroom HMO with full internal reconfiguration and external insulation.
Structural Alterations in Chiswick: what to know locally
High-value Victorian and Edwardian terraces and semis, including the Bedford Park estate and the grid streets off Chiswick High Road.
Chiswick properties carry high values, so the specification expectation is correspondingly high — sash window matching, proper brick selection and detailing that stands up to close inspection. Much of the area sits in conservation designation.
Planning authority: Hounslow Council. Hounslow applies strict conservation controls across much of Chiswick, and Bedford Park in particular has detailed design guidance. Anything affecting the front elevation almost always needs permission.

Structural Alterations in Chiswick — questions
Do you cover Chiswick?
Yes — Chiswick and the W4 postcodes are part of our core working area, along with Acton, Hammersmith, Ealing. Being local means a site visit within days rather than weeks.
Which council handles planning for Chiswick?
Hounslow Council. Hounslow applies strict conservation controls across much of Chiswick, and Bedford Park in particular has detailed design guidance. Anything affecting the front elevation almost always needs permission.
How do I know if a wall is load-bearing?
Direction of the floor joists above, thickness of the wall and what sits above it on the next floor are the usual indicators, but it is not always obvious. We establish it on site and have an engineer confirm before anything is cut.
Do I need building control for a knock-through?
Yes. Removing or altering a load-bearing element is notifiable work. You get a completion certificate, which your conveyancer will want to see when you sell.
Can you convert a house into an HMO?
Yes — we have done full reconfigurations including taking a three-bedroom property to six bedrooms. Beyond the building work it brings in fire separation, escape routes, room size minimums and licensing, all of which we work to.
