For now.. I'll leave with some inspiration.
Look at this beautiful penthouse in Ostermalm, Sweden. It has totally six rooms divided on 261 sqm. Quite big if you'd ask me. It's very modern and absolutely gorgeous. I love the space and use of furniture and not to forget about all the light coming in. Some of the windows are 9m long, and if there's something I love in architecture.. It will be massive windows.
What do you guys think?
