Holland Park is a neighbourhood of large Victorian villas and houses arranged around garden squares, and both facts shape the work. On VOA figures, most homes are flats, many inside divided villas, where the freeholder's licence to alter comes first. The whole houses are generous, with wide rear returns and rooms big enough to justify serious structural alterations. What they rarely have is a way in from the back, so everything uses the front door. Along Holland Park Avenue and the streets near the Kyoto Garden we appoint the structural engineer early, so the steel is specified before anyone works out how to carry it in.
For Holland Park the Council Tax list gives about 4,280 homes; by type 81% flats and 19% houses, by age 28% post-war, 4% interwar and 67% older than 1919. VOA Council Tax stock of properties, March 2025, for Holland Park. Counts rounded by the VOA.
Side returns, rear returns and wide openings need a goalpost
The standard villa plan puts a front room, a rear room and a return wing under one roof, with a narrow strip of ground running beside the return down to the garden. Infilling that strip and taking out the return's flank wall is the biggest change you can make to one of these houses, and the most structurally involved: house extensions for the infill, RSJ installation for the opening. That flank wall carries the return roof and often part of the first floor, so removing it usually calls for a goalpost arrangement of two beams and a column rather than a single lintel.
New foundations for the infill sit alongside footings that are shallow and were never designed to have anything dug next to them, so the engineer sets a depth and a sequence for excavating in short bays rather than in one open trench. Drainage almost always crosses the strip, which means a gully or an inspection chamber has to be relocated or built over, and building over a public sewer needs an agreement with the water authority. Rainwater from the new roof also has to go somewhere the existing system can take.
Communal gardens and the front door route decide the steel
Where a house backs onto a communal garden there is no vehicle access to the rear at all. Scaffolding has to be carried through the hallway in components and built by hand, spoil comes back out the same way, and the garden itself needs boarding and protection before anyone stands a standard on it. Garden committees generally set their own conditions about working hours, storage and reinstatement of turf and planting, and those are worth agreeing in writing before the first delivery rather than with a scaffold already half erected and a neighbour watching.
That access reality feeds straight back into the structural design. A beam that cannot be carried through a hallway and up a staircase is the wrong beam, however elegant it looks on a drawing, so the engineer is told about the route at the survey and specifies accordingly, whether that means a spliced section, an extra column to shorten the span, or a lighter grade at a reduced clear opening. The same applies to plasterboard sizes, bath dimensions and anything else that has to turn a half landing, which shapes a bathroom renovation in an upper flat. Working this out at design stage costs an hour. Working it out on delivery day costs a fortnight.

FAQ
Building work in Holland Park: common questions
How do you get a steel beam into a house with no rear access?
In sections, or by choosing a design that suits the route. We measure the hallway, the door widths and the staircase turns at the survey, then give those dimensions to the structural engineer so the specification accounts for them. A long beam can be supplied as spliced sections bolted together in position, or the span can be broken with a column. Where a window opening is the only viable route, it is removed temporarily and rebuilt afterwards.
Will an extension affect the drains?
Almost certainly, because the drainage from a Victorian villa runs down the side return the extension will occupy. An inspection chamber may need relocating, gullies rerouting and the run rebuilt in modern pipework to correct falls. If the new structure sits over a public sewer, an agreement with the water authority is needed before building. We survey the drainage before pricing so the work appears in the quotation rather than arriving later as a variation.
What is a goalpost frame?
Two steel beams and a supporting column arranged like a goalpost, used where an opening is formed at the junction of two walls that both carry load. In a Holland Park villa that typically happens where the rear return meets the main house and you want the kitchen to read as one room, which is open-plan conversion work. The engineer sizes both beams and the column, specifies the base plate and connections, and we build precisely to that detail.
Do you work on flats as well as whole houses here?
Yes, and flats are most of the stock. Many of the villas have been divided, and we work on individual flats within them as well as whole houses, with freeholders and managing agents where a licence to alter is required. GS Renovation coordinates building control applications and inspections. The installations we carry out come with a five year guarantee.
