We are Proficiency, a bespoke design and Build construction company in London. Proficiency excels in fine luxurious loft conversions, house extensions and renovations. Established in 2011.

We then look after all aspects of the build, the approved drawings, building control, the structural engineering calculations and provide complete detailed schedule of works.
We will be with you all the way until your loft conversion is delivered to you fully decorated and any snagging is complete.

At Proficiency we provide two services:

A Design and Build where every aspect of your project is being managed by us from design, planning, party wall agreement and finish of the project.

Your building project will start with an on-site assessment with one member of our design team that can assist with all the aspects of project whether it is to transform your loft space or simply adding an extra room by having extension.

We also offer the construction only. You may already have an architect and we can work along with your Arhitect's plans and specifics.
