Extensions above garages (side of house)

[joropug]

Looking at houses at the moment,

One we like is link detached via single story garage. The neighbouring house extended above the garage with planning permission, only objection was a random neighbour (not the house for sale) and it was approved. Now if we wanted to do the same, is that likely to be rejected as you'd have to join up to the other extension and essentially downgrade it to semi detached ?


The other house we like is fully detached. Could benefit from the same extension above side garage. What sort of scenarios could cause it to rejected ? There are no similar planning permissions lodged online for that road. I just think it seems fairly safe considering a linked detached property was fine.

The adjacent house has a small window on the side that could get less light, looks to be a stairway / small bathroom window though.

Many councils have advice on house extensions, often known as supplementary planning guidance.

It is quite common for them to require that any 1st floor extensions retain a 1m gap to the boundary, in order to avoid the 'terracing' effect you refer to.

Do not assume that it is a race between houses to be first to get to the boundary. It usually does not work that way.

And to be set back from the front elevation.

Councils don't look at it the same way. Round the corner from me, someone with a semi on a decent corner plot built a house onto the end of his, "downgrading" the other person's semi to an end-terrace. But, "possible reduction in property value" is not one of the criteria planning committees consider.

The other thing to consider is that the person who extended over their garage knew that someone else could come and do the same, but human nature dictates they might be a dick if you do. So consider how important neighbourly relations are to you when formulating potential plans for the house.

ETA I missed the bit about a window... If that's on the wall you would be building up against then I doubt you will get permission without an agreement from the other householder that the window can go. Doesn't sound like a means of escape from your description.
