Would anyone look at my floor plan and give me ideas for an extension?

[Shortofspace]

Big ask, I'm finding it really hard to visualise anything other than what is already there! Have lived here for 5 years and meant to extend straight away and do the kitchen. Don't want a conservatory anymore I think would prefer an extension, roughly the same size as the current kitchen. I want/need a dining table space for 6 and more storage. I would LOVE to get a downstairs loo in the bit labelled "store" which has the washing machine and tumble dryer in it.
Hoping someone who's done an extension (or just likes house plans) could give me some ideas. Obviously I need to get an architect but I'd like to think what's possible first!
Thank you to anyone who's bothered reading this far. Will post plan in first comment.

Plan:

Ok, first question, are you surrounded by similar houses and if so are there others with extensions? If there are, you may be able to find their plans on the council website or on rightmove if they’ve been up for sale.

What is upstairs? Is there anything else you would like to squeeze in like a wfh area?

Good question! We are in a semi, with the other house on the "store" side. I can see a couple of neighbours with conservatories and one with an extension and a conservatory (!) I will try to look that up. All single story so I feel I would get permission for that ok but prob not for two floor (and I can't afford it). We have two double and one single bedrooms upstairs, and a bathroom (the only one). Looking to the future it would be good to have a ground level loo and more space for when the stairs become a challenge! (Only 50 now but probably won't move from here). 2 dc who'll probably be at home into their 20s. Thank you for replying.

What's your budget and whereabouts are you?

Is your back garden big enough to accommodate your extension plans if you were to double the size of your kitchen?

First impressions, I’d do something like this. Create direct access from the hallway to the rear and block off the second door from the front room to avoid a corridor feeling. Put a loo and utility in the store. Keep the kitchen where it is and put dining and sofa/snug in the extension so you can enjoy garden views.

Have a nosey on Rightmove to see what all your neighbours have had done.

The garden is about 50 ft long and only slightly wider than the house (by an alleyway). At least we have rear access without going through the house.
I know I should have a budget I'm assuming it would be 35-50 thousand to build but could be wildly out. We have some inheritance recently. In a city, in Scotland.

I’m thinking something similar to the amended floor plan above, just extend the whole way across the back. Make you’re store into a utility room on the kitchen side, and a cloakroom that you get to from the hall.

Don’t completely discount the two storey extension idea. I did it and got planning permission despite one architect refusing to even apply as she was so sure it wouldn’t be granted, and two others who don’t think it would happen. In comparison to the overall cost of the extension, an extra storey adds a tiny amount, but extra rooms upstairs make such a big difference.

@MsShopper that's exactly what I would do! Although I don't think that would be possible on 40k, even in Scotland...

Have you considered a diagonal extension?

I don't know what that is! Off to google...
Thank you all for your replies, and @MsShopper for the diagram, that's already given me a perspective I would not have thought off!
Extending right across - would mean we are right up to boundary with neighbour which I thought might cause problems with repairs etc.

You can just nip in a little bit at the side if there are boundary issues. Ours ended up not quite going across the full length of the house, but that was for cost reasons rather than the boundary.

I think your budget is way off, sorry. We're in the North East, deprived city. Had a quote 2 months ago for various works. One of the things they quoted for was to change the existing conservatory into a proper room- put a roof on with velux, insulate better, plaster, put flooring down and plaster etc. Was £40k for that alone. And the foundations, walls windows and electrics are in place. (Conservatory is about 12sq m for reference).
I really don't think you can build a whole extension for that kind of budget, sorry.

Thank you, that's a good reality check. I do have more money available, but we wanted to pay the mortgage off as well as sort out the kitchen. We could move things around a bit. What I've thought off is a permitted development size building keeping most utilities where they are now to reduce costs - the waste pipe already comes through the back of the utility, for example.
When I know what I'd ideally like I could cost it and take it from there.

Is the idea of about £2,500 per m2 nonsense then? I've read that in quite a few places.

Unfortunately it is an exceptionally bad/expensive time to do building work right now - labour and materials both very pricey after covid and brexit.

Are you able to wait a couple of years? I would if you can.

It's a lot more at the moment unfortunately. Ours will only be about 7m² and quotes coming in around £40k (excluding vat) to a plaster finish.

Admittedly we're on the outskirts of London & that includes some slightly more expensive options (reclaimed stock bricks, pitched roof rather than flat, & we need to move the boiler).

Architect, structural engineer & planning fees were about £3.5k.

From memory, I saw a similar cost bandied about when we did ours but that's for the shell. You'll have architect fees, planning fees, decoration, new kitchen with fit out, glazing, decoration/furnishing and all the other bits and pieces on top of that.

Thanks for all your replies. Honestly, I think by the time I was planned and ready to start a couple of years will have passed!
I'm not sure I can fit a utility and a wc in the store space. Maybe loos don't take as much space as I think.
My family love the kitchen having two doors and seem to use the downstairs as a kind of circuit

How much is the house likely to be worth at the end?
Where is your current conservatory and what type of construction is it?
You may want to really think about rejigging your existing layout. I was originally going to go out further. Have a kitchen extension but a very long garden. However the cost even a few years ago were crazy in relation to value of house (also Scotland).
We took out the store kind of arrangement you have to open it all up. Terrace so not quite the same but being clever with the existing space made much more sense, especially if you can improve the conservatory. There's a good episode of Love it or List It where they put a roof on the conservatory.
People keep referring to my extension but it is the same footprint, just used better.

Have what works for you - we didn't really need a full utility so we're keeping the downstairs bathroom instead as we have a dog. We have a shower upstairs so will have a bath downstairs.
We're having a laundry cupboard - basically just stacking the washing machine & tumbledryer - which will free up some space in the main kitchen area.

We were quoted £40-£50k for the shell of a 9x3m rear extension last year. This didn't include the kitchen or flooring necessary. We are in the Midlands.

We have a downstairs 'lootility' which is about 4.5 ft x 6ft! It functions perfectly well (loo, sink, stacked wm and td along the 6ft wall), so you have plenty of space in that store room.

You could apply for planning for the two storey, if you get it it'll add value even if you don't build two. If you don't nothing much wasted.

A rough idea

Planning for two storey sounds good - you need different foundations don't you?
But learning I can't afford one storey never mind two!
I wouldn't mind having the loo in the utility, but I wouldn't want the door to be straight off the kitchen - at the moment if we put a loo in the store has three doors (to the hall, the kitchen, and the back door) which wouldn't be much privacy!
We don't have an existing conservatory, maybe I should just get one with a more solid roof as surely that would be quicker.
