Changes in exterior materials and form help define the various zones of this family lakeside home

A concrete bridge with steel balustrades above this family home’s central living area connects the parents’ and children’s wings. Each of the three two-level loft-style bedrooms are designed to accommodate two children. Entry to the rooms is through a galvanised steel door on a sliding tracking system, while plywood panels between the doors have a colour wash in the children’s favourite colours.
