Thanks for your input! It’s a one bed flat so it’s never going to have more than one or two people in the cooking area so I know 900mm is the minimum ideal gap but I’ve had it lay out on the floor in cardboard and it’s doable. I wasn’t planning on a dishwasher as at the moment it’s just me who will be living there and I can’t justify it. I’ll get Howdens to give me a cost to weigh it up. I’ve got until the end of April before I need to place the final order. If the end 600mm unit is the place for the DW then the position of the island doesn’t impinge on accessing it hopefully! The rad is existing but will be swapped out for a 600mm vertical, my mistake not changing the plan! It will be moved far enough away from the F/F :) I had a 1200mm breakfast bar in my last house and it was plenty big enough for 1-2 to dine. I will have a table and chairs in my garage that can be brought in when I have friends over.

Thank you for your replies. Ellie- both rooms are a nice size but we want to incorporate a living area into the mix aswell hence the extension. Also I don't think the current kitchen is wide enough to make that into the dining room Jonathan- I look be the plan but I don't think the dimensions are quite right. For example, the wall where the long side of the sofa is is less than 1m in length so wouldn't fit in the current layout. I hadn't thought about the kitchen to the left side though so might give me more ideas to play with ☺️

Jonathan, moving the bathroom as you have was actually Plan A but I got cold feet about the cost of moving the bathroom although I loved the idea of a line of sight from front door to back garden. We only roughly sketched it and having seen your beautiful floorplan I am thinking we’ll regret it if we compromise instead. The bungalow looks so much more balanced than it does at present and has a flow to it, which it currently completely lacks. Thank you so much for taking the time to draw it up so nicely :) love the addition of a cupboard in hallway to bedrooms and one in entrance hall as Rinq latterly suggested (completely agree on need for this Rinq) and access to toilet from garden - have 3 year old and 10 week old so very necessary, as is catching the mud before it comes indoors! Can I just ask, on the right hand side of kitchen is that recessed cupboards? Ps. You got the layout of our sofas bang on ;D

I think if you moved the toilet over to the fireplace wall in the dining room then the dining room becomes basically a corridor between sitting room and kitchen. Having it tucked under the stairs is prob best use of space. Could you not use the dining room as a dining room still, with the kitchen (I assume it's a one wall set up) and island in the kitchen as that is the largest space. If you have pocket doors or barn style doors leading to the sitting room you will save a lot of space for the dining table. Agree with Rinked that more light would be a good thing. If no scope to put in a rooflight could you break a window(s) either side of the fireplace?
