We had a house with a timber ceiling - it is a tricky decision. If it is a cheap display home build perhaps cover it, but if the quality is good it is a much harder decision. I think it looks good now and could be made very interesting. Also that look is "back". Make sure your lighting is very good and the heaviness will dissappear somewhat. The floor is lovely.

Oh wow. I had trouble even believing that was the same space - until i saw the window seat. Do you have even more rooms to share?

What you have created is a beautiful clean open space. But that is only the foundation. Now what is needed is you. You need to inject your personality and your family’s into the space. For nowhere do I see anything that tells me who lives there. And this is something you can add to as you live and use the space - in effect turning a gorgeous room into a home. Perhaps a vase of flowers on table or photos on sideboard or yes perhaps eventually changing mirror to a piece of art that grabs you. The trick is to not rush this stage. Live with the room and gradually add items you love to personalise it as yours. You have created a beautiful backdrop now it just needs you.

Do you have any furniture you are wanting to put in there ? Does any of it have any colour ? I like the light floor colour , the rest let's just say it is a good neutral base . I'd start with a new front door -- a darker varnished ( glossy ) wooden door , or possibly even a blue to reference your outside . Then add colour via furniture ( or at least cushions ) , rugs , and artwork . Again , maybe several different blues would tie in with the floor , but also the exterior . If there are only blue exterior highlights , you may want to go for warmer colour inside -- reds , yellows , oranges -- again , ties in with the floor . To this end , I can't understand why people go with 117 shades of grey and offwhite and wheat -- live a colourful life is my attitude , as long as it is themed haha !
