GS Renovation carries out structural alterations throughout Shepherd's Bush, working on the Victorian and Edwardian terraces that make up so much of W12. Whether you need a new opening, replacement joists, a supported opening into the side return or underpinning to a settled corner, our founder's 30+ years on the tools mean the work is engineer-led and signed off by building control.
In Shepherd's Bush, a simple new opening starts from £1,500, and underpinning a single elevation typically costs £6,000 to £21,000 (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Shepherd's Bush.

How the job runs
- Free site survey at your Shepherd's Bush address and an itemised quote.
- The engineer we appoint designs the work, and it is registered with Hammersmith and Fulham Council building control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
- Props and any trial holes first, then the opening, joists or underpinning in the engineer's sequence.
- Building control inspects each stage before it is covered, then issues the completion certificate.
Alterations to Shepherd's Bush period homes
The bay-fronted terraces around Shepherd's Bush lend themselves to a familiar set of alterations: widening the opening between kitchen and closet wing, forming a new doorway through a structural wall, or replacing tired floor joists that have sagged or been notched over decades of pipe runs. Each of these changes how load travels through the house, so we treat them as engineering tasks, not cosmetic ones.
New and enlarged openings are formed with a correctly sized steel or lintel bearing onto padstones, with temporary support in place while we cut. Replacement joists are specified for span and spacing, and where the ground has moved and a wall has cracked, underpinning deepens the foundation in controlled bays. Nothing is guessed; the engineer's design governs every step.
Housing in Shepherd's Bush
The stock in Shepherd's Bush runs to roughly 13,640 dwellings, 87% of them flats and 12% houses, built 53% before 1919, 17% between 1919 and 1939 and 29% after 1945. Most homes here are flats, and structural repair to a block in Shepherd's Bush usually falls to the freeholder under the lease, so it is agreed with them before anything is opened up.
Lowering a Shepherd's Bush lower ground floor flat
In a converted Shepherd's Bush house the lower ground floor flat often has the least headroom, and digging the floor down looks like the obvious fix. In Hammersmith and Fulham that can count as basement work. Full planning permission is needed to create a new basement or extend an existing basement, and this includes flats and maisonettes as well as single dwelling houses. The flats above share the building, so the freeholder's consent and the planning application run side by side.
The application needs a Construction Method Statement, and the scheme has to satisfy Local Plan Policy DC11 (Basements and Lightwells). Two of its criteria matter most for a flat. A basement must not comprise more than one storey, with exceptions possible on large sites. Beneath any garden there must be a minimum of one metre of soil above any part of the basement. Underpinning walls that carry every storey above is also one of the most sensitive structural jobs in a converted house, so the method statement is written with the engineer, not added afterwards.
Building control sign-off across W12
Structural alterations inside a Shepherd's Bush home are governed by the Building Regulations, so Hammersmith and Fulham Council's building control oversees the work, not the planning department. That distinction matters: internal openings, joists and underpinning are not planning matters in an unlisted house, whereas external changes may need planning permission (always for a flat), and a listed building needs listed building consent for internal structural work too. We keep the two clearly separated so you are never chasing the wrong consent.
Where a new beam or underpinning affects the shared party wall with the neighbouring terrace, the Party Wall Act also applies: you serve the notice as building owner (or your surveyor does) before starting, and we supply the drawings and programme it needs and build to any award. We arrange the building control inspections at the stages the inspector needs to see, from foundation bays to beam bearings, and the council issues the completion certificate you will want when you come to sell in W12.

FAQ
Frequently Asked Questions about Structural Alterations Shepherd's Bush
How accurate is a structural alterations quote for a Shepherd's Bush house?
The accuracy of a structural alterations quote in Shepherd's Bush depends on the information behind it. A phone figure will move; one written after GS Renovation has checked the W12 property usually does not, because the load path through the Shepherd's Bush building decides where support lands, and that is only visible on site. The Hammersmith and Fulham Council building control fee is shown separately, and the range to compare against is £1,500 to £21,000 or more, from a simple opening to underpinning one elevation (indicative).
Do I need planning permission for structural alterations in Shepherd's Bush?
Usually not for internal work. New openings, replacement joists and underpinning inside your W12 home are controlled under the Building Regulations, so Hammersmith and Fulham building control signs them off rather than the planners. External changes may need planning permission, and always do on a flat. If the building is listed, internal structural work also needs listed building consent, and doing it without consent is a criminal offence. We confirm which applies before we start.
Can a wider opening be formed into the closet wing of a Shepherd's Bush house?
Yes, where the house has one and an engineer has sized the steel. In a Shepherd's Bush house with a closet wing, that wall usually carries a rear bedroom or bathroom above, and the floor often drops a step into the wing. The opening is cut to the engineer's calculations, propped while the brickwork is removed, and inspected by Hammersmith and Fulham Council before plastering.
Who needs to agree structural work in a Shepherd's Bush flat conversion?
The freeholder, under the lease, before anything is cut. Most leases treat altering structure as a breach unless written consent has been given. Building control then assesses the design. If the flat sits in a listed building, internal structural alterations also need listed building consent. Only once these are settled does the propping start.
How do old solid brick walls in Shepherd's Bush behave when a new opening is cut?
With 53% of Shepherd's Bush dwellings built before 1919 (VOA), openings are usually cut through solid brick laid in soft lime mortar, with no cavity. The brickwork above an old opening often rests on a timber lintel that may have rotted. Cutting slowly, supporting courses above with needles, and replacing timber lintels with concrete or steel stops the masonry from dropping.
When does underpinning come into a Shepherd's Bush structural alteration?
When the engineer finds the existing footings cannot take the new load, for example where a beam concentrates weight onto one pier. Victorian foundations are often shallow. Digging near next door changes the paperwork: if the trench falls inside 3 metres of their building and drops below its footings, they must receive a month's written warning under the 1996 Act before any spade goes in.
When did permitted development for basements end in Shepherd's Bush?
In 2018. Hammersmith and Fulham Council's borough-wide Article 4 direction removing permitted development rights for basement development was made on 25 April 2017, confirmed on 16 April and in force from 26 April 2018. Since then a new or enlarged basement in Shepherd's Bush has needed full planning permission, including in a flat, whatever an older neighbour's scheme or an out-of-date guide suggests.
How far under the garden can a Shepherd's Bush basement extension go?
No further than half the garden. The Local Plan basements policy requires that a basement does not extend into or underneath the garden further than 50% of the depth of the garden. For a lower ground flat with a short rear garden that limit can be tight, so the garden is measured from the rear wall to the boundary before the engineer sizes any scheme.
Does a Shepherd's Bush basement scheme need a flood risk assessment?
Where the address is in a flood risk zone, yes, and two thirds of the borough is. The borough's planning guidance asks for a flood risk assessment with an application for a property in one. Under a lowered floor it bears on the tanking or drained cavity system, the finished level and whether a non-return valve goes on the drains. Commissioning it early lets the basement layout respond to it.
