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 architects will measure up and draw plans
ready to submit to your Local Authority.
Prior to submitting to the
Local Authority, draft plans will be submitted to yourselves for approval. Once
the plans have been approved and signed, they will be submitted to the Local Authority
for determination under the Section 63 of the Town and Country Planning Act General
Development 1990. (approx 2-3 months for approval to be granted)
Some
properties may not require planning permission, provided the loft conversion is
the first extension and does not exceed 40 cubic metres on a terraced property
and 50 cubic metres 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.
All flats require planning permission.
Once planning has been
approved we will then prepare Building and Fire Regulation plans and submit to
your Local Authority Building Control department for design appraisal and structural
calculations to justify the proposed design to the Structural Engineers department
for checking and approval. (approx 4 - 6 weeks for approval)

we will then serve the necessary Statutory Commencement Notice upon the Local
