This is the current lounge, front, and kitchen

My initial thoughts that neither option work well in two areas. Bedroom 3 upstairs is really tiny and would be better as the bathroom and the bedroom re-built elsewhere. The Kitchen is too small on both plans. Do you have any drains that you can access to the right?? Otherwise it's difficult to improve on Bed 3. Re- Plan 2 upstairs, I don't know how you're going to achieve the bathroom in that position as the soil pipe will be in the middle of the house. The drains first and foremost dictate the build. Therefore it's imperative to know where they are. Maybe if you could answer the above, then we can all have a little peruse on the matter. Without all dimensions and answer about drains, I think you need to be heading more in this direction:- Therefore, this is just an 'artists impression' The master bed can still be extended a little without impinging on the roof below it which i presume will have veluxes in it.

Hi Hayley - it would be best to show the plan I drew to a builder and they can give you an accurate quote. There are no doubt going to be costs involved in blocking up the door, adding a new cooker/oven, new extractor fan, new units and new worktop plus labor costs. So I couldn't give you a figure and it would be best sought from a professional in the trade who can visit your house and assess what needs to be done and what limitations your kitchen has etc. You may also decide after the cooker has been moved that you want new units, worktops, floor and wall tiles across your whole kitchen? So it sounds like a bigger a job than you might think! Its the DIY domino effect, once you start you can't stop!!

Back from hols, bit of sunburn but I didn’t forget about your dilemma:-). Had spare time today so did some sketches although looking back at your photos I realized the shed has door on the right rather than in the middle but you can alter things as you wish. Please bear in mind that I’m not a professional, just someone who loves garden planning and sketches are rough guesses from the given photos and not to scale. So far as I can see the majority of the garden is well laid out. The patio by the French/bifold doors, the raised planters and the shed are in a good position and I don’t see any necessity in altering them. There are a couple of issues which i think I’ve tried to address in sketches. The pod seat looks a bit shoved up the corner so I would try and relocate this so it’s more involved in the garden and inviting to sit in. Perhaps replace that corner with a specimen tree or shrub suitable for small gardens. https://www.gardenersworld.com/plants/20-trees-for-small-gardens/. As mentioned before the picket fence I would remove as I think it blocks flow, I think I’d rather fence off the dogs rather than kids so perhaps by re using some of the fence to create gates between the main patio and the rest of the garden would enable you to give a bit more free space for either the dogs or kids, whichever prefers which. I notice the lawn is seeing a lot of foot traffic so by adding another pathway the other side of the raised planters should enable you to access other areas of the garden without stepping over the lawn. In sketch 3 I’ve tried to give you an extra patio for evening sun by extending the triangle but not sure if that’s poss but should be enough for a bistro set. Where I put low or ground level planting I was thinking something like ornamental grasses and such which I’ll post a few inspo pics. I do realize that I’ve decreased the amount of lawn in most but I do feel that the extra planting and pathways will help to bring the garden together and make it feel more intimate. Anyway, I’m waffling on, feel free to carry on or change my ideas. Try different layouts by using a garden hose or string and pegs, but most importantly work out where you’d like to sit out most and what you would like to view when looking from windows and of course pick plants for the right place.
