FREE CONSULTATION VISIT
From your initial inquiry, our consultant will visit you and quickly determine the feasibility and potential of your loft. (Minimum height in loft space to the highest point 2.4 metres / 8 feet). After measuring, your specific requirements will be discussed with you and advice will be given to you on what is the most suitable conversion for your property. Shortly after your consultation, you will receive a full specification and fixed price quotation that is valid for acceptance for 30 days.
Once you have accepted our quote and decided to use Loft Masters to convert your existing loft space into a habitable room, our surveyors will measure up and draw plans ready to submit to your Local Authority. We also have the facility to also use an external registered firm of Architects for large commercial projects.

Some properties may not require planning permission, provided the loft conversion does not exceed 40 cubic meters on a terraced property and 50 cubic meters on others. This condition only applies when properties are not located in a Conservation Area and are not at the junction of two public highways.
