To help you understand these issues we detail below some of the "conditions" attached to planning permission and building regulations. (These apply to England/Wales only) Scottish, Northern Ireland, Eire and North American regulations are quite different - You should in all instances take local advice. For information on the rules for Scotland click here.
PLANNING PERMISSION
In England and Wales you will not usually require planning permission, provided you do not exceed the permitted development limit for your property (which is 50-70 cubic metres, depending on where you live). Notable exceptions to the above are listed buildings and conservation areas. Please note that if your property has been extended in the past - you will have used up some or perhaps all of your "permitted development" area and may need permission. Its also worth noting that occasionally "permitted development" rights may be withdrawn from a property and any extension however small needs planning.
If in doubt check.
BUILDING REGULATIONS
Generally speaking conservatories/sunrooms on residential property are exempted under Building Regulations.
Below are some of the Exemption Criteria - under the Building Regulations 1991 (as amended). These criteria must be met for a conservatory extension to be classified as exempt:
a)
The extension has a completely transparent or translucent roof.
b)
The extension walls are substantially glazed. (Should not have more than 25 % of its wall area as brick work)
c)
The extension has a floor area not exceeding 30m squared.
d)
The extension is sited at ground level.
e)
The extension is permanently separated from the remainder of the property by means of a door.
f)
Any radiator within the conservatory is controllable. (If fixed heating installations are proposed, they should have their own separate temperature and on/off controls).
g)
The glazing satisfies the requirements of part N, Schedule 1 (toughened/safety glass).
h)
The extension does not contain any drainage facilities. (i.e. sink, WC, or washing machine)
An example of where building regulation approval may be required is a Kitchen / Conservatory
Extension. We suggest you contact your local council - explain your intentions - they will be able to give you more specific advice.
As a further guide conservatories that require building regulation approval will
need glazing of the highest insulation quality i.e. - Pilkington K Glass (low E)
with argon filled units.
