Residential renovations


There are a number of stages to a home renovation project and we work with homeowners to support them as the project progresses. 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 home

We undertake all sizes of property extension projects in and around Mayfair, 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.

Converting your loft


Why not 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


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.


Convering a property into flats


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.


Listed buildings

USL Architects are experienced in delivering projects on both Grade i and ii listed buildings, ensuring that the building's details and history are respected while maximising the potential of the property.
