Why Ushii in Mayfair
Ushii delivers loft conversion work across Mayfair (W1) with directly employed trades. Not a broker, not a list of numbers passed to whoever is free that week. The carpenters, roofers, electricians and gas engineers on your Mayfair site are on our payroll, which is why programmes hold and standards stay consistent from strip out to snagging.
Mayfair works are rarely straightforward. Grade II listed terraces on Mount Street, floors in mansion blocks off Park Lane, family-office headquarters behind Georgian facades on Grosvenor Street. The pattern is consistent: expensive material, tight programme, private client, and no tolerance for unfamiliar faces turning up in the wrong colour van. We deliver with our own people, every one directly employed by us.
Prime central planning departments expect measured drawings, heritage statements and a considerate constructors approach to hours, deliveries and noise. We prepare all of it before a single tool arrives on site.
A good loft gains a bedroom. A great one gains a floor of the house that feels original. We spend as much time on the stair, the head-height and the eaves storage as we do on the roof itself.

Common questions
Loft conversions in Mayfair, answered.
How much does a loft conversion cost in Mayfair?
Cost follows scope, access and the condition of the building rather than the postcode. After a survey in Mayfair we issue a fixed, itemised price so you can see exactly what each element of the loft conversion carries. There are no provisional sums hidden in the back pages.
Do you work on grosvenor estate townhouses in Mayfair?
Regularly. Grosvenor Estate townhouses, Mount Street apartments, Park Lane laterals all feature in our Mayfair workload, and each one is surveyed on its own terms before we price anything.
Which areas near Mayfair do you cover?
We work across Belgravia, Marylebone, St James's, Knightsbridge, Fitzrovia and the wider London area, with a directly employed team rather than local trades brought in for the day.
Will we lose the room below the stair?
Not usually. We design the stair position around your existing plan; we will show you the impact before you commit.
How dusty does it get?
Loft works are the dustiest part of construction. We install a fully sealed dust screen at the head of the existing stair, and vacuum-extract every day.
