I'm submitting an application for prior approval for the addition of a full extra storey to a house. In addition to that I am proposing a number of alterations which are straightforward permitted development and simply require a certificate of lawful development. Can these all go through on the same application? Locally I have seen other prior approval applications in which the drawings show both the proposals requiring prior approval, as well as those which are straightforward PD. Other than being shown on the plans there is no reference to the straightforward PD proposals. The design statement and report focus solely on the elements of the proposal requiring prior approval. There is no separate application. The architectural technologist we are working with does not seem certain.

Yep. Those are fab.

Most of that is pretty straightforward though. More design guidelines than hoops. And protected views, air traffic, conservation, etc.. are simple to get a good steer on in advance. Completion target than commencement within 3 years is a bit more risky.

Not looking to extend above garage.

Thanks. What do you see as the main hoops are for AA? (Everyone I have spoken with is wary of it or entirely unfamiliar). General design specs would be OK (max height etc..) I can't see overlooking, loss of light or privacy being an issue (the row is south facing and a good distance from properties behind). I don't think any of the other listed exceptions apply. Foundations need checking. With AA you need to apply for permission with regard to the external appearance of the dwellinghouse and that seems like it could be a bit troublesome - extending the first in any terrace upwards is arguably conspicuous / incongruous. But then that's the nature of the permission so it would seem odd if it could fail on that basis?

Agree that carefully considered design is key. Yes it's terraced. Just bought it and exploring different options. Luckily I'm used to part wall shenanigans!

Thanks. PD applies equally to the principle elevation unless it is considered to front a highway. What constitutes fronting a highway is not clearly defined. Intervening uses, buildings, distance, angle and land uses are all factors. Just trying to get a steer on our set up. (The garage is already there).

I was looking at adding a storey to a house but then wondered whether I might be able to achieve most of the extra space with a front and rear dormer. PD for the front dormer would be dependent upon whether the house is considered to front a highway. The house is set back from the road by about 15-19m. Between the house and highway are a hard-standing, 2 single storey garages (ours and our neighbour's) and front garden - each about 5-6m in depth. Half the frontage is occupied by the neighbour's garage. The ground floor of the house - and front garden level - are elevated about half a storey above the ground floor of the garage. Our garage is marked green in the picture below. Might it be more conclusive if the garage and forecourt were in separate ownership (shown by the green dotted line)?

Through the flat glass roof.

Cheers for the suggestion. The extension will be built up to the boundary which runs east west. So anything providing shade to the roof between about 10-4 would need to be in the neighbour's garden. Not going to happen!

Believe me that if there were scope to install PV here I would have done so - I have two 4kw arrays elsewhere. Listed building, conservation area, awkward roof and mostly shady garden... 🙄

This is where I am coming from!

Thanks for the suggestions. I have to admit I feel that if the design of the new extension relies on an air conditioner, it is probably not the right design.

Today is the first I've heard of the A2A mini split unit. Not quite sure what it is but will look it up. Some kind of air con?

Thanks. I'll ask about these calcs.
