Our proposal was based mainly on the low budget, adapting small new details and keeping most existing furniture. We focused on the children's room - with most changes - but trying to put keep the costs low. So we created two large walk-in closets, placed a wall of drywall (can be made from wood too) and covert with wallpaper (or just painted). In the kitchen area we kept the island but expanded with a new section bar - a dark color wood - dining and a smaller rack. The important thing is the change of the counter with a new, dark and unified. For the space of the library proposed two solutions with inspiration from large libraries. For reading two reclining chairs offer comfort and are part of the living - sitting area, which has changed the layout. Existing Sofa pieces positioned to welcome the visitor, but also to provide direct view outside. If you gonna varnish the floor its better to give it a darker tone.
