Anyone bought a house with a view to adding a granny annexe?

So, the big plan is: DM has sold her house and bought a 1 bed retirement flat. We are currently tarting up our 3 bed tce to sell.

Equity from house + bigger mortgage (ours is currently tiny) + proceeds from DM's house is to buy us a bigger house with better chance of decent secondary school that DM can have her own seperate space in, for when her health (which is not great) deteriorates and she needs more support. (Currently lives ~70 miles away)

Anyone done this or similar? Any property pitfalls etc to look out for?
Is it better/cheaper /easier to go for a property with a big garden and get a prefab annexe or to build on the house?

We've had a sensible discussion about ground rules and boundaries and DM and myself are definitely on the same page. DM definitely wants to be as independent as possible and I am an occupational therapist so have an idea of space &design requirements etc for single person with largely age related medical conditions. Not much clue about builders & planning permissions etc though!

All advice & experiences welcome! Feeling a bit daunted...

Friends did this. They bought a detached house on a large plot, knocked down the single storey garage to one side and built a bungalow (2 bed) on the garden to the side, with a path between the two houses for elderly parents.

The houses are completely separate and the plot is capable of complete division to allow for either house to be sold separately with its own gardens. At the moment some of the garden/access is shared.

The main house did need quite a bit of work and it's taken some time. The bungalow was up in no time once they had planning permission though.

Dreadful grammar there - the path wasn't for elderly parents, the bungalow was!

I think the only thing to be mindful of is that if you need planning, nothing is guaranteed.

We bought a house with a large garden with the intention of putting an outbuilding in the garden and we were refused permission. No to say that you will, just maybe have a plan A, B & C! In our case we'll get there in the end, It's just going to cost is a lot more than we'd originally anticipated a straight forward approval would.

The planning permission round this can be a little exciting (exploring adding granny annexe to current house in footprint of garage).

If it will only every be 'ancillary' to the main house - as in, only for your relatives [or, oddly, domestic servants!] to live in, then the situation is relatively straightforward. However, it is much harder to get planning permission to create an annexe that might at any point have a separate use - our garage is falling down, so we want to build the annexe now, let it out for a few years as a small separate flatlet, then use it for granny in the future. Locally, that is much harder to get permission for, and certainly wowfudge's development would not be allowed in our road.

We have a longer term 'what to use it for before / during / after plan', and a long chat with a local planning person was helpful in clarifying that we MIGHT get permission but only with a 'unilateral declaration of something or other' to say we never intend to sell the two bits separately, which is a condition that would end up being on any permission we got IYSWIM?

We didn't buy for this purpose, but we did build a separate home for DM when my Dad died. She was determined to have her own front door - the only link between us is through a shared laundry, and it's a very well worn path. smile

Mum has been with us for over 12 years now. She is amazing, very respectful of our privacy, we've benefitted from her great cooking and general help, and the DC have a wonderful relationship with her.

We bought a house with annex of sorts attached and completely refurbed it. Have a large shared garden which mum and my husband both love and lots of sheds! Also share a utility which is really useful. Both have own front door garage but also pay two lots of council tax two phones separate elec and gas. Though oddly the water is joint. Lots and lots of pluses for us and my children love it. They wonder through for nana cuddles in the morning. Occasionally things flare up but 2 years on its all much better. Living altogether during the refurb of the annex and our kitchen was stressful though! Good luck with it all.
