Why Our Building Company

Your Personal Project Manager around Brent Park and NW10

The Proficiency way is to lodge every loft conversion project with a dedicated project manager. You'll meet your project manager as soon as work begins on your NW10 loft conversion. This project manager will be your reliable point of first contact throughout the project. You can rely on your project manager to keep you (and everyone else on the team) fully informed about the work being done to your new loft. He will also supervise all the work executed on-site and ensure that the project sticks to its work schedule.

Brent Building Control

At a higher level, you can expect a Brent building control officer to visit the site regularly to confirm that every detail meets the latest requirements set forth in the building regulations. And the end of the process, you will receive a completion certificate following the building control inspector's final inspection.

Full Certification Handled For You

Following the receipt of building control approval and the completion of the project, the Proficiency team will deliver a completion folder to you. Here you'll find all of your conversion's important documents gathered together. This includes your building completion certificate and certificates for electric and gas, manufacturer's instructions and guarantees, and a certified 15-year guarantee on our structural work.

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.
