For starters your T.V. is way too high lower it to sit virtually on the mantel and take all the stuff off the mantle. If you are getting storage built get 2 made so one on each side of the fireplace for balance. I don't see what you have for lighting now and find the finish on the walls very busy. When I look at your idea books I am not really getting that same feel in the space as it is so maybe some more pictures would help with that.

Can't decide whether to mirror the wall above the loo and sink area or put in wall hung mirror with light fixture above ... or buy a hib mirror with built in light? Any advice??

can that wall be remover between kitchen and table? if so could you put a narrow island in kitchen with a table/counter running off of it into current dining area. this would be alot narrower and allow for more storage unser the window plus open up ypur living space more. also furniture is very dark for a small space and table and chairs seem very big. could you paint ceiling white and light fixture a brighter colour.. all these things should make it seem bigger. the picture i have attached would be quitw narrow and just an idea i saw on houzz.

Looking for ideas for updating front door and vestibule/porch area. Do I keep and update exterior sliding door or replace? I'm edging towards a light green for our internal door as goes with interior scheme. Hall quite dark so thinking of moving light fixture inside interior door and keeping as much glass in doors as possible. Any one with similar set-up or a creative brain that can share ideas? I'm stumped! (Didnt know how to add photos so included below in comments). Based in Cork city.
