Specialists in central London property projects


USL Architects has the experience and skill sets for a number of specialist architectural services. This includes working in central London with listed buildings, conservation areas, landlords and estates. Working with landlords on the client  behalf especially for requirements  such as an LTA (licence to alter). Prior to undertaking major works in flats or leasehold properties the leaseholder will normlly be requested to obtain consent from the freeholder or landlord. We can help in the process to produce drawings, documents, coordinate and liaise with the landlords surveyor towards obtaining the LTA. we have worked with domestic and larger landlords and estates such as :


  • The Crown Estate

  • Grosvenor Estate

  • Portman Estate

  • Cadogan Estate 

  • Local authorities

Residential renovations


We work with London homeowners to support them through the stages of their home renovation project. These include feasibility studies, concept design, planning applications, party wall services and building control drawings and tender packages to obtain quotes from builders and contractors.

Extending your London home

We undertake all sizes of property extension projects in Central and West London, including one and two storey extensions, rear and side extensions and loft conversions. Our team is experienced with working with local authority planning department to take the stress out of the planning application process. Currently, in some areas you can apply for ground floor extensions up to 6 to 8 metres in depth

Converting your garage


These days it's common for garages to be used as storage for clutter rather than for storing the car. Make better use of this space and convert it into a habitable room, a bedroom, home office, utility room or hobby room, with a window in the front for added natural daylight. We can prepare and make the planning application on your behalf

Converting your loft


Space is typically at a premium in London homes so why not make use of your property’s existing loft space to create additional bedrooms or living space. We can help you make the best use of the additional space a loft conversion can bring to your home. We can prepare and submit application under 'permitted development rights' or 'planning application' to include a dormer conversion


Party Wall services for London property projects


Home extensions and loft conversion projects often involve a wall that is shared with a neighbour, called a party wall. We can help you through the process of notifying neighbours of work and ensuring all of the necessary steps are followed including issuing of notices and the final award. We can act as your party wall surveyor if you are undertaking the works or in response to a notice issued by your neighbour.


Converting a property into flats in London


Thinking of converting your property in to flats or an HMO (house of multiple occupancy). We can help with a feasibility study to establish the possible number of units, prepare a detailed scheme design and the planning applications.
