Why Our Building Company

Dedicated Project Management Services in NW20

At Proficiency, we take pride in offering our customers a dedicated project manager to handle their project. At the start of the project, we will introduce you to the project manager. He will be your unique point of contact throughout the entire duration of your loft conversion in either Totteridge, Whetstone, Woodside Park or Oakleigh Park. The project manager will do everything it takes to keep you posted on the progress of your loft transformation. You will be able to know at any given time how the progress of the work is going. He will also be responsible for the supervision of your roof space transformation to make sure everything unfolds in accordance with the agreed schedule.

Routine Building Control Checks

One of our building inspection experts will ensure that all the latest laws and building regulation requirements are met at every stage of your project. These regular reviews will be followed by a final inspection, once the loft conversion has been completed. You will then receive a completion certificate issued by a building control inspector.

All Paperwork Supplied

After the completion of the build and building control inspection, we will provide you with all relevant documents. The documents will include the building completion certificate, electric and gas certificates, and all manufacturer's guarantees and instructions. In addition, the folder will contain 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.
