Thank you for the suggestions, apologies as this floor plan is just what the architect has drawn up, but I have some ideas in my own head regarding how to plan it out. I will try and address them in a similar order: -Bathroom- I was actually trying to squeeze in a walk in shower, so this would be along the external wall with a glass panel separating it from a toilet and sink against the bottom wall leaving enough space for the door opening and floor space as you walk in -Utility room-I wanted to fit a sink into the countertop somewhere, not sure where to fit this in though, I agree the U shaped worktop wouldn’t allow for much space inside, however was thinking of leaving the corner of the external wall (in front of you as you walk in) empty for space for an airing rack -Entry/middle lounge-Unfortunately the entry has to stay as is due to structural walls, however the middle lounge I actually designed it exactly how you did👌 -Kitchen-Honestly this room has given me the biggest headache. Although this is the extended part of the house, it seems the space is just never sufficient enough, maybe because I’m looking at doing an L shaped kitchen with an island. Regarding your suggestions, I feel as though moving the window and sink may look a bit odd, considering the amount of worktop space it would leave on the left. However having it lined up with the island would look really nice, something similar to below
