In my opinion, I think there's little coherence in either option. Option 1 looks like three separate extensions and Option 2 looks like two separate extensions. All a bit 'bitty' for me. Neither option looks as though it offers vast spaces, which is great if that is what the client is looking for.

Hi! I'm Chorlton based too! There are lots of ways you could tackle this. To answer your questions: 1. It depends on your budget! A lower cost kitchen might be around £10k and a lower cost bathroom around £2k to fit out. Cheaper is possible, especially if you look at buying second-hand etc. You could spend your money where it's going to give you the most impact and longer term investment - in the bricks and mortar part, and go the lowest cost route possible for the kitchen and bathroom, even reusing what you've got already where you can, but in a new configuration, and then later on when you've got some more budget you could replace the kitchen and the bathroom as straightforward fit-outs. You can spend as much as you like on a kitchen and bathroom - the sky is the limit! Equally there are lots of clever ways around things to bring it within budget. 2. Depends if the wall is structural or not. It doesn't line up with the ground floor wall, which tends to suggest that it isn't but it's best to check. Either way it's possible to move the wall because you can always add in a steel, but equally there's potential to make a corridor taking part of the bathroom to reach the extension. 3. There is no strict requirement to retain the existing roof pitch, but there are planning issues that can restrict/limit what you can do. There are different ways to approach the roof form. I think you may be thinking of permitted development. You can also apply for extended permitted development, which allows you to extend back further. If you're looking for a 2-storey extension then to get your best solution it may be better to just apply for planning permission and get what you want, without restricting yourself to PD. Again you have options. If you'd like to have a free chat with me to talk this through then you can book one in here: https://calendly.com/iarchitect/20minchat

That looks like a lovely spacious house, big windows etc! I know what you mean about pebble dash but it looks like it's in good condition and I agree that it would look a bit odd if you paint it, unless any other houses in the street have already done it. Extensions are usually built in a modern style which complements rather than matches the original house. In terms of the materials used, there may be a style that's developed locally for modern buildings, so it's a good idea to have a look around, even having a look at your council planning website as that will give you a good feel for what is being passed by the planners. Eg we're having an extension built at the moment on our 1930s house which will be a mix of wood cladding and cotswold stone - we're in the cotswolds so this works with the local vernacular and other modern buildings around here.

Hi there. Can I see floor plans to suggest you some ideas. It will help to visualise the house so can explain in more detail.
