House extension Blackpool

As we have experienced a severe downturn in the economic climate it is not 
always a viable solution to move house so a house extension can be a perfect 
alternative especially in an area like Blackpool. 

Many house extensions on the Fylde Coast do not require planning permission and can be pass 
through as permitted development. 

Extensions do not have to be huge or cost the earth but they allow you to create 
that extra bit of space that you have always desired. 

If this is something that you have been thinking about but not sure where to start and you live in Blackpool or the local area 
then please call Architect Blackpool now to discuss your options.

three metres. 

• Maximum eaves and ridge height of extension no higher than existing 
house. 

• Side extensions to be single storey with maximum height of four metres and 
width no more than half that of the original house.

• Two-storey extensions no closer than seven metres to rear boundary. 

• Roof pitch of extensions higher than one storey to match existing house. 

• No extension forward of the principal elevation or side elevation fronting a 
highway. 

• No extension to be higher than the highest part of the roof.

Planning permission or planning consent is the permission required in the United 
Kingdom in order to be allowed to build on land, or change the use of land or buildings
A number of different types of planning permission can be applied for:
 
1. Full planning permission: A full planning permission would grant permission for 
all aspects of the proposed development, although it would generally be subject 
to various conditions (see below). 

2. Outline planning permission: Outline planning permission cannot be granted for 
a proposed change in the use of land or buildings. It might be appropriate when 
an applicant is seeking an agreement "in principle" to a proposed development, 
without being committed to a particular form of design or layout. 

3. Approval of "reserved matters" Seeking permission for those aspects that were 
not dealt with in an outline planning permission, or seeking approval of aspects 
of a development which were reserved by a planning condition in an earlier grant 
of full planning permission. 

4. Renewal of planning permission: This would arise when an earlier outline or full 
planning permission was subject to a time-limiting condition which has since 
expired. In essence this requires the entire planning application to be reviewed in 
light of current rather than previous planning policies. Applications for renewal of 
an earlier planning permission are usually granted anew, unless there has been 
a significant change in the relevant material considerations, which are to be 
weighed in the decision. 

5. Removal or alteration of a planning condition: As a matter of law, conditions 
should only be imposed on a grant of planning permission when compliance with 
that condition is essential to make an unacceptable development acceptable – 
so it would be refused planning permission were it not for that condition. 

If the applicant or developer wished to proceed with a development without 
compliance with a condition, or perhaps with the condition in an alternative form, 
then an application can be made to "vary" the condition concerned – possibly by 
deleting it or offering an alternative form of words. Note that the LPA cannot alter 
any planning condition which imposes a time limit when the development is to be 
commenced. That would require a re-application for full or outline planning 
permission, but since October 2009 it has been possible to apply to extend an 
existing consent. 

6. Hybrid A local planning authority may accept a 'hybrid' application; that is, one 
that seeks outline planning permission for one part and full planning permission 
for another part of the same site. he fee for each part would have to be calculated
 separately on the appropriate basis, 
subject to any relevant maximum, and the total - which would not be subject to any
maximum - would then be chargeable. 

An authority may also, following discussion, allow 
an application to be separated into core elements so that permission for site preparation 
works, say, can be given priority. Whether to accept a proposal in hybrid form is at the 
discretion of the local planning authority, not something on which an applicant may insist. 

One should bear in mind that a local planning authority is empowered to require details 
even when the application is in outline, if necessary in the interest of good planning. The 
term ‘hybrid application’ is not defined in statute
