thank you for this interesting project.
The apartment space is quite challenging, at first glance has many opportunities but not many of them fully meet the brief and your wishes.
I've tried several options and I have concluded that this presented arrangement would best meet your needs and standards.
My main aim was to give each space individual attention and make a coherent living space without sacrificing any particular area to make another better.
I've decided to keep everything on the same plan without adding any mezzanines since I concluded that an addition like that would compromise one of the functions of the apartment and all your needs could be met in a single plan organization.
While aiming to meet your needs, equal attention was given to the design of the space as well.
Looking at the references you provided I decided to go with darker shades and a cozier mood with a touch of elegance and luxury, and this atmosphere is incorporated into each room.
More information about the design is included in the proposal.
All additional information about the project, if choosing it, will be provided, including specifications of the built-in furniture.
