What country and state are you in? That will affect whether you need a fireplace. I like freestanding bookcase/storage units, they must be attached to the wall if tall and not deep. If getting custom built get at least 3quotes. Finally, there are DIY shelves available at hardware outlets and stores like Ikea.

Strong geometry, cool blue and glass and a plain lawn background. to fill the diamond with bush is going to cancel out its strength. But something different to the slightly sterile design compilation … if the finance is there, get two or three massive raw rock slabs and one spectacular architectural tree. resist going vertical .. layer them horizontally to slightly overlap or break the hard lines of the diamond, but not to obscure it. Then choose you vertical with a sculptural tree. There are vertical cherry trees with spectacular autumn colour which would contrast with the rocks (texturally), and be floaty like the water in the pool…. whatever the tree, lift the foliage up from the soil level, and underplant with jut one kind of tight low ground cover, even moss (if your climate can support) or ground hugging juniper that you can train inside the diamond. This combination of elements is rich for the eye, softens the geometry, and adds interest which is lacking right now. The place for shrubs and grasses and palms is to border the lawn.

i love the pictures that Siriuskey has posted (this site is so frustrating in that you cannot reply to other users!!), the stone work is fabulous - and window seats would complete the cosy, ski lodge feel - but those TVs are so high up! I am Not a fan of tvs over fireplaces, especially with such a spectacular architectural opportunity on the wall behind it. it is possible to get artworks positioned on a track to cover the tv if there is not another possible location for it. just a thought!

Having the dining table on front of the windows like you suggested won’t be an option I think. We tried and it looks awkward especially because we won’t get a 3 Meter table in there without looking overly crowded. Additionally we were thinking dying sliding doors towards the garden there and having an outdoor lounge area. The dining table would then block access. However we noticed that off cantering the dining table under the bulkhead doesn’t look too bad. And a solution for the dining table light could be a straight light with two suspensions left and right of the bulkhead.
