First of all, I want to say that the place is very beautiful: the white color, the natural light that comes inside and the uniform wood like texture on the floor, make it a neutral and peaceful place for the people who live or are going to live here. This is very important.
The project is very simple, and tries to locate the furniture in the best way to keep the places spacious, and design the rooms [its color scheme, the objects selected, and the places to rest and storage things] to create a single space, and a fluid route around the apartment.
For that –after you see the images–, I propose to eliminate the door between the atrio and the relax zone. It would make the place less small, considering that the furniture you have already [sofa, dining table and chairs’ set] occupies an important quantity of space.
The idea is not to deplete the resources by overloading the place with a lot of objetcts, but to let you complete it, following the main scheme and having the option in some areas of the house, of personalizing some of the furniture with your own necessities.
