Don’t settle with an empty, unused loft. There’s more to your loft than just being an empty space for storage


We offer a comprehensive loft conversion service in the Harrow area, inclusive of an on-site assessment by a member of our design team. Our Proficiency team are fully qualified to assist with all aspects of loft conversions, from architectural drawings to planning and application. However, if you already have architectural drawings from a design team you prefer to work with, we will be happy to build according to their specifications.

We will provide you with a complete schedule of works and handle all aspects of the project, from the approval of drawings to building control and structural engineering calculations. We will work with you every step of the way to ensure that your loft conversion is completed on time and delivered to you, fully decorated and snag-free.

Why Our Building Company


At Proficiency, we believe in dedicating a project manager to each project. On the first day of work, you will be introduced to the project manager in charge of your loft conversion in Harrow, who will be your first point of contact. The project manager will keep you in the loop and ensure that everyone connected with the conversion is fully informed about what is happening on the site. He is also in charge of supervising and reviewing the progress of the project to make sure that it is moving ahead as planned.


One of our Harrow building control officers will regularly inspect the work in progress throughout the project to ensure that all the latest building regulation requirements are met. Once the build has been completed, a building control inspector will make a final inspection and issue a completion certificate.


After the project has been completed and building control approval has been obtained, we will provide you with a completion folder containing all the documents relevant to the conversion, including the building completion, electric and gas certificates, all manufacturer’s instructions and guarantees, and a 15-year certified structural guarantee.

The dormer loft is built vertically on top of an already existing sloping roof and requires relatively simple building works.

Hipped Roof

A hip end is the sloping end to a roof and a gable is the triangular section of wall which stands between two sloping roofs.


Roof with sloping window pointing towards the sky fitting to the roof-line and leaving the original roof structure untouched.


Located to the rear of the home, with a flat roof type and back wall sloping inwards at an angle of 72 degrees.
