As I say, I can't reconcile the dimensions. There appears to be a 2ft ( roughly ) discrepancy across the width of the house. ie, if the kitchen is 22ft long, then I can't make the lounge, Hallway and study fit in to that measurement. The lounge and study add up to 19ft, which would leave 3ft for the Hallway and staircase, so that wouldn't work, and something is amiss. Also, the study is down as 1.45m which isn't 7'10".......I had to make it a rough guide! So, this is what i'd go for as a plan b, following the initial amendment upstairs.................If you did the extension.............it would look roughly like this:- I managed to fix the dimensions, so later i'll put them back on Plan A x

I definitely like that you’ve gained a clear run from the hall way so you can see out to the back. I don’t think having the dining space diagonally really matters and as you say you gain extra light there. Also depends how much you use the table/living room/kitchen. I often Potter in the kitchen so would want that to be light enough to not always need to turn on lights, and often sit on the sofa and read so the same, but only eat evening meals at the table so it’s less of an issue, but if you use it all day, or have kids drawing there then you’ll have different priorities. I think if you can block off a small corner to create a utility cupboard that might be useful to help reduce noise in the open plan space. I think you could potentially do well discussing with a concept planner for the room. Many people on here have used OnePlan and recommend her. I think there are lots of options and everyone will have opinions of what works better but Presuming you’re doing this for you and not to sell then there’ll be additional considerations of your preferences and how you’d live in the space. :-)

hi Kat by the time you waiting for a planning and finalised drawings and you saying you sent your documents for planning its a right time to get estimate by the planning drawings till they turn up with a tender spec. if you have clear idea about what would you like to have maybe its better to skip the tender spec and make your own decisions as a guide for a builder to price. compare to a size of your project you can assume flexibility from a builder for certain changes during a time of a built. if you have existing bathrooms for example which were stay as its is with no layout changes (studwall movements) its a right time to start to rip them off and start to 1st fix them up also as you would have underfloor heating (not to sure if its piped system) builder can start to expose floors and insulate them through and make all pipework/electrics ready for a next phase which would be your loft and extension. if you issued your planning and you have structure engineer drawings on place too its a time think ahead if you need any party wall agreement on place you would need to start to work on it as it can slow the process of a build (or just propose it for your neighbours involced). other things as like find out main water pressure and main water upgrade is a right way too to start with as with that amount of upgrades old pipework might don't have enough pressure so good to submit applications for water authorities as nowadays it can takes up to 8-10 weeks too to have a main connection to be done.

We are in the process of extending (a joint project with our neighbours to gain an extension to the front box room, then along the ground floor across the front and down the side of the house). We're having some last-minute layout dilemmas, the floor space isn't the biggest, but we will gain some essentials from it (bigger kitchen, downstairs shower/toilet, office space, porch and the bigger box room upstairs). Our shower room is going to be fairly slim (worked out as 900x2900mm at the minute). This also creates a slim corridor space beside that leading to an office which I've bumped along a bit to give some more space (sacrificing utility space at the other end, when you compare my Ikea layout with original drawings). The other option is to access the office from the lounge, meaning we could lose the corridor altogether and widen the shower room, but that would make the office open to noise from the lounge and I think it's a weird place to add a door. We're also struggling with options for the laundry/utility space too and whether to just include it as an extension to the kitchen. I've added some screenshots and links to an Ikea planner I used to map the ground floor out completely (ignore the colour and the basic mapping of furniture etc. it also doesn't include the pitched roof and Velux windows). Any input would be appreciated, I'm just looking for layout ideas and tips for anyone that has similar sizing/spacing set-ups. Thanks.
