Extensions & Loft Conversions in Broadgate
We build extensions and convert lofts across City of London. Much of the Square Mile is covered by conservation areas and listed buildings, and the Barbican has its own listed building guidelines, so even internal changes can need consent. Expect to agree working hours, lift use and deliveries with the building's management before starting.

Local knowledge
Working in Broadgate
Homes in City of London
Homes here are almost all flats: the listed concrete towers and terraces of the Barbican and the neighbouring Golden Lane estate, plus apartments in converted offices and warehouses around Smithfield and Aldgate. There are very few houses, so work is internal and usually inside a managed block.

FAQ
Extensions & Lofts in Broadgate
Not answered here? Call 07595 386864 and ask us directly.
Do you carry out extensions & loft conversions in Broadgate?
Yes. Broadgate is in City of London, where we work every week alongside Barbican, Smithfield, Aldgate and Blackfriars.
Do I need planning permission for an extension?
Not always. Many single-storey rear extensions and loft conversions fall under permitted development, which has size limits and does not apply to flats, maisonettes or some conservation areas. We check your property at the site visit and tell you which route applies before you spend anything on drawings.
How long does an extension take?
A typical single-storey rear extension takes around 10 to 14 weeks on site once approvals are in place. A loft conversion is usually 8 to 12 weeks. We give you a written programme with the quote so you know what happens each week.
Can we live in the house during the work?
Usually yes. We seal off the working area, keep a kitchen and bathroom running wherever possible, and agree the noisy or dusty days with you in advance.
