Apologies for length, I really need some opinions. I posted something on houzz not long ago but only received replies from pros looking for work and I am not at that stage yet. Our house has a very badly built lean-to utility room which runs the length of the house alongside the kitchen. It is made up of a few different original sheds and toilets that were attached to the house, with some bricks in the middle to join it all together. It is a waste of space as the door to access it is at one end of the kitchen and it's so narrow that things can only be put at the other end, so is essentially a long corridor leading to a few things. It has very dodgy electrics and water comes in under the door/around windows. It houses our boiler, a chest freezer, washing machine and has a sink unit and a bit of worktop hanging off the wall!
My initial idea was to extend the kitchen out entirely, incorporating both the lean-to and passage running alongside it, to make it around 6m by 6m and have a proper utility room and downstairs loo within this space. The kitchen desperately needs ripping out. It's also dark, despite being south facing, because it has very narrow sliding doors with a conservatory on one side and a brick shed on the other, casting shade. We would knock the shed down and put in much bigger doors for more light. I think this will cost roughly 40 grand. There are a few complications, our boiler having to be moved, soil pipes from bathroom running down that wall and the whole thing sitting on concrete, which I guess would need to be removed first. On consideration, I think it could easily become more than 40 grand. This would take up all of our savings and require us taking out a mortgage. We currently own the house outright.
(I have a little sketch of our current kitchen and proposed space if anybody is interested - will upload in a bit. Can also upload a little drawing of our lean-to/collection of outbuildings to make it clearer)
The issue is that it is a lot of money. We live on a council estate with a bit of a reputation, though we like living here and have never had any problems. It has improved over the years and continues to improve with new housing being built within the estate. Our house is currently worth about 115, which is cheap compared to other houses of this size in the local area. The most houses on our estate have gone for recently is about 130, though they hadn't been extended or done as nicely as we would do ours. I did see that a house a few streets away recently went for 140, though I don't understand why because it needed modernisation. We wouldn't be adding 40 grand of value to our house.
One other option is to stick with the kitchen as it is, move the door for accessing the lean-to into the middle of the wall and try to make a useable space in what is still an outdoor room. I want a downstairs toilet and guess that without it being properly built as part of the house, it will be cold and damp. The kitchen is currently quite narrow, only 3m, and has a chimney breast, so placing a table is different. My piano also has to live in this room. This option doesn't really help with the light, though I think we could still get a wider set of sliding doors in. This would obviously be cheaper and enable us to get other work done more quickly. The windows at the front of the house need replacing, we need a new driveway and porch, new patio and various other things.
Another option is to only extend halfway, so incorporating just the current lean-to into the space and not the side passage that runs alongside it. This would again be cheaper, but not sure whether it's worth the cost and upheaval to only gain an extra 1.5 metres on the side, which we'd still need to fit a utility and toilet into.
I can draw a little picture of the different options if it helps clarify things for anybody. I would be so grateful for some different opinions and ideas. I had my heart set on the full extension originally, but can see the appeal of not spending so much on it. Over the past couple of days I came round to the idea of not extending at all, but trying to fix the lean-to. Now I'm chagimg my mind again! I'm going to see a neighbour's house this weekend. They haven't extended and have a toilet in the lean-to, which they use as a utility room. It has been properly built and rendered. Will see how I feel about their layout. What would you do in my situation?
