PP requirements for garage conversion at the same time as extension

tom1ie

Hi all,

We are planning on getting a sunroom extension of our living room and knocking the wall between the living room and kitchen.

At the same time we want to convert the adjoining garage into a utility, downstairs toilet, and a study.

We have an existing extension that was built above the garage- sometime before 1977 but after 1966.

So my question is, will the garage conversion come out of the 40m2 PP allowance?

In other words if the existing above garage extension is 20m2, and the garage is 15m2- this would only leave 5m2 of an allowance for the sunroom extension before i need PP?

Am i calculating that correctly, or would any works converting a garage to a habitable room(s) count as taking away from your PP allowance? ie you are just changing the internal layout of your existing house?

Thanks for any help

You asked this before and I answered at the time.

Hi Muffler,

sorry but this is a separate question.

We got the PP issue for the above garage extension sorted so now im asking if i do anything in the garage itself will this take away from the 40m2 allowance?

It will. The area of the extension previously built has to be deducted from the 40m2 limit. Just to note that the sunroom will require pp if it's going in the front or side of the house.

Also, maybe it's a typo or a very strange extension but you indicated the extension was bigger than the garage below it. Is that correct?

It will yes.

Yeah correct.

So the extension above the garage extends past the garage onto the top of the kitchen.

So the Garage is actually not as long as the house as the kitchen is behind the garage running perpendicular to the garage if you get me.

The existing extension straddles both the garage and the width of the existing kitchen.

The sunroom will be going on the back of the house up tight to the boundary wall.

I suppose the next step is to get the architect out to measure:

the existing extension

the proposed garage conversion

the proposed sunroom extension

and if we are over 40m2 its off to get PP- correct?

Correct.

Many thanks muffler this is the route we are going down based on the builder recommending we talk to his architect, but I just wanted to get some views on it.

Just out of curiosity, how was the extension sorted. Did it have planning permission?

It did in the end- but the architect the vendor employed had to go looking through various council departments etc etc.

I would try and explain it but I’ll probably just muddy the waters.

Assuming the rooms are rectangles, it should be pretty straight forward to measure the width and length and confirm the area of each room. Even if L shaped, it's something the kids could do.

FWIW, a garage and an extension already eating into the 40sqm, there's no way there anything worthwhile left for the sun room, imo
