Larger House Extension Applications

Good afternoon,

Looking to submit a Larger House Extension. The extension is at the rear with a maximum dimension of 5m deep. However the property is slightly 'L-shaped'. Therefore part of the extension is only projecting 3m. Part of the extension is therefore a side extension as well as a rear extension. The side extension would be less than 50% of the maximum width of the property.

Does the fact that a part of the extension is a side extension affect the Larger House Extension Application? i.e. does this type of Application require the extension to only be a rear extension?

Any thoughts would be really appreciated.

Kind Regards, Ian

It's difficult to visualize what you intend ( a simple sketch plan would help) but so far as I can make out, the Larger Home extension scheme would not be applicable in your case, and you would probably need to apply for planning permission.
The ‘squaring off’ of extensions wouldn’t normally fall under the PD requirements. Those types of extensions would have to be considered under the PD rules for both side ‘and’ rear extensions.

As @tony1851 mentioned, do you have plans or layouts we could review?
thank you both for your replys. done a quick sketch showing proposed extension

Unfortunately that would need planning permission and could not be done under the Larger Home Extension scheme.
The reason is that your proposed extension would extend beyond a side wall of the original dwelling and be more than ½ the width of the dwelliing.
However, if the sticking-out part was not original but a later add-on, then it's side wall would obviously not be 'an original side wall of the dwelling', and your proposal could be done under the Scheme.
Having said all that, if you applied for planning permission, it's quite likely you would get it, as it doesn't seem to have much of an impact on any adjoining properties.

Thanks. The only way that could work is to reduce the 2m down to 1.1m.
