Design
Requirements
We are happy to provide an initial design
idea for clients and / or builders from
photos and simple survey information.
A description of the proposed extension
such as Mansard Orangery 7 x 4m with bi-
folds facing out to the garden is enough for
us to put an initial sketch design together
along with a few photos of the property.
Permitted Development
Buildings which are
behind the principle
elevation of your
property and under 4m
in height can usually be
built under permitted
development.
We have a range of
standard designs which
fall under permitted
development or we can design something to suit.
You can apply for a Lawful Development Certificate if you want some
paperwork to prove that your building is allowed under permitted development
rules. Some people might like to see some evidence that your building complies
if you sell your property but it’s not a necessity.
When Does Permitted Development Apply?
An oak-framed building, such as a garage, garden room, or extension, may
qualify under permitted development if it complies with the following
guidelines:
Purpose and Usage:
•
The building must be incidental to the main dwelling (e.g. a garage, home
office, gym or storage).
•
Living accommodation, such as an annex, often requires planning
permission.
Size Limits:
•
The maximum
height is 4 metres
for dual-pitched
roofs or 3 metres
for other roof
types.
•
Eaves height
cannot exceed 2.5
metres if within 2
metres of a boundary.
•
Total ground area covered by outbuildings must not exceed 50% of the land
around the original house.
Location Restrictions:
•
The structure must not be in front of the principal elevation of your home.
•
It must maintain appropriate distance from boundaries.
•
Some areas, such as conservation zones, national parks, or listed properties,
have stricter controls.
Special Designations:
•
For properties within areas of outstanding natural beauty (AONB) or similar
zones, restrictions on size and placement may apply.
Roof Design:
•
Flat roofs are restricted to a maximum height of 3 metres.
•
Balconies or raised platforms are not permitted under permitted
development.
