My parents are building a family house in Middle East. They have gone as far as raising the structure and putting ceilings in place and will soon start with surrounding walls. It's planned as G+M+3, Ground Floor is split between parking space and a shop. M is considered for separate guest unit ( As is common in the region, specially for those with frequent visitors) it's an apartment with living room, bedroom, storage, small kitchen,...etc. The other half oh mezzanine floor is an extension to the shop.
On top of these we have identical space for 3 spacious apartments (2-3 bed) which will be used by my parents, myself and my brother's family.
They have been given complete set of layouts by the local designer which is attached for your review but am big believer in crowdsourcing platforms (though this is my first project here) and creative talents contributing on them. So, I would request you to check the file and offer an alternative layout if you think space can be used more wisely ( considering we can't touch the space for lift and stairs). Then offer a classic design theme (for +65 Y.O couple) and one contemporary. You can do it as details feed suit and we are happy to continue with preferred design on this site for any extra details.
I hope the details are clear but please feel free to ask any clarification.
