AD50: a 50 square metre master suite addition with retreat and ensuite
AD50 is a single storey rear addition of 5.0 by 10.0 metres that puts a complete master suite at the back of the house: retreat, bedroom, walk-in robe and ensuite, each in its own right.

What is in the design
The addition is 50 square metres with roughly 43 square metres internal. The retreat is 4.5 by 4.0 metres with a 2.0 metre sliding door to the yard; the bedroom is 4.5 by 3.45 metres and takes a queen or king; the walk-in robe is 1.9 by 2.1 metres; and the ensuite is 2.5 by 2.1 metres with a 900 shower, WC and 1100 vanity.
The separation is what makes it work: the retreat is a room of its own with a door to the garden, so the bedroom does not have to be everything at once.
The connection to the house is the same throughout this collection: a new 1800 cased opening through the existing rear wall, lintel designed by an engineer.
This design suits a house with good bedrooms up front and nothing of its own at the back, where the master suite ends the queue for the main bathroom.
Drawn for a level site with clear access, not bushfire-prone, standard wind (N2) and soil (Class M). Site works, services connections, planning and permits are assessed for each site.
Concept design. Site-specific drawings, engineering, an energy rating and a building permit are required before construction.
