Does anyone have a definitive interpretation of permitted development rights in terms of an extension which is more than 4m high and within
2m of the boundary? The 4m rule is when part of the extension is higher than 4m AND within 2m of the boundary. So it is possible to build higher that 4m if kept 2m from the boundary.Is the interpretation of the 4m rule, that "no part exceeding 4m high can be within 2m of the boundary", or is it "no part of the extension as a whole, can be within 2m of the boundary"?
If the latter, is it possible to build the gound floor as 'one extension' under PD, and then add the upper floor as a 'second extension' still under PD? Both extensions will be within the PD volume allowance
For example, if one extension was built first (ie a ground floor extension), then if a first floor extension was added later (albeit straight away) then is this taken as a separate extension in the context of "an extension higher than 4m and within 2m of the boundary". Or are both the extensions deemed to be one 2-storey extension?
In effect, two extensions will be built and my reading of the GPDO 95, is that it is the part of the building which is enlarged (ie the first floor) which is the crucial factor.
The wording of the GPDO is vague. I am looking at it as two extensions
- one will be built within 2m of the boundary but under 4m high, the second will be built more than 2m from the boundary but more than 4m high.
Individually, both will be PD, but the fact that they are joined, may be open to interpretation that they become a single extension - in which case it will then be within 2m of the boundary and not PD.
Cheers
