If you're still keen on a flexible-function room (i.e. where the middle internal space works as a guest bedroom or family space for example playroom, snug TV room, office, hobby room), my suggestion would be to use pocket internal doors; and/or glazed internal french doors. Then most of the time the doors can be open and part of the open-plan. Then when using the the space as a guest bedroom, the doors could have roller blinds or curtains, to separate the space and add privacy. Consider which way you want the "flexi room" to open up. Rather than open up to the side of the house (near proposed cloakroom); I think it would be nicer if the room opens into the back room or the front room (likely to be much nicer views and better light).

Hi SteffyTaylor, is it worth extending 1m back? Will you loose too much garden for gaining not a huge amount of space? Personally I think I'd spend the money on big bi-fold doors all along the back elevation. As the kitchen is staying where it is I'd suggest having the dining table running adjacent to the RH wall in the photo and have your living area opposite, with dual aspect into your new courtyard and garden. Lots of tall plants in the courtyard would be great and I'd think about adding a door from the bedroom (as well as the extension) out into the courtyard, that would be a lovely place to have breakfast on a summer's morning! Hope these ideas help! PB

Hi Suzanne, The stairs i had in the drawing were my version of what i thought it would look like before we got formal drawings from the architect (bit of cut and paste of existing plans). I do have an updated version he did i'll post here. However on this plan the bay at the back of the kitchen is too narrow and we haven't got the side windows shown in the kitchen etc. The stairs i had shown have a half landing. Our current stairs have 2 quarter landings. The stairs only go up 1 floor - 15 steps (15th being the landing level). We are also constrained by some eaves so the steps can't come up directly onto the landing by the wall due to head height issues - i have shown this with a red line. Happy to consider any stair variants you mentioned. I will take a look at stairbox.com thank you. The hall is approx 7.5m by 3.5m if you include the utility/coat cupboard area in the overall space. Thanks again for looking at this for us!

Could you repost the floorplan a bit clearer with some rough measurements please? And with neighbours on the right you mean the ones your kitchen+bathroom is NOT connected to? And with a party wall already in place would they agree with an extension on the full width?
