The Hill Street Project


Update on the amazing Hill Street Project in Mayfair.

The Hill Street property is located close to London’s bustling Berkeley Square in a prominent position in one of Mayfair’s finest streets.

Brompton Cross Construction has been awarded the renovation of this substantial heritage building from apartments into a single family dwelling. Set over seven floors with a total internal floor area of 9480 ft2.

Top left Picture shows the silo and conveyor belt from the basement dig. All basement materials are taken out via the conveyer belt to a ship in the external hoarding and removed by grab lorry 2-3 times a day Silo is to supply concrete for the basement temporary and final slabs.



The main stairway construction was installed by Wilcox fabrications this runs from 5th to ground floor. The stairs installation was critical to install to a 10mm tolerance due to a glass lift being installed in the centre of the stairs, we got it to 4mm tolerance.


Internal Rooms:

The internal rooms are M&E first fixed with main ceilings up and under floor heating installed. The walls have been rendered with timber or metal battens fitted vertically to take the finishing wall materials I.E Timber battens = timber decorative panels,  Metal stud = plasterboard then plaster.


Basement Conveyor:

This photo shows the bottom end of the conveyor belt in the basement, this will be in place until the end of the basement dig to remove all soil.


We have progressed the front elevation rooms on levels 1-5 up to plaster stage. All M&E first fixed with the back elevation rooms 1-5 completion of main structural works still in progress.

Basement temporary slab has started with the main piling to commence on the 2nd Aug.
