Media summary

The Greeny Flat continues work at the Mount Stuart Greenhouse (2019), redeveloping a 6x6m garage/rumpus for a solar array and secondary dwelling.

A thin roof profile of seamless low-profile solar panels, sits atop a verdant hedge, minimising  impact within the historic home and garden site.

With sound construction, ample floor area and valuable basement-level storage/workshop, the existing footprint remains. Replacement of the hipped roof with an over-scaled north-northwest facing skillion yielded maximum power generation when studied with Red Sustainability.

An L-shaped open-plan arrangement, with fully-functional kitchenette, dining nook, reading corner/ child-sized beds and fold-out queen bed, is organised around an ensuite.

Expansive city views through an oversized window reaches from table-height sill to the peak of the raked roof-line.

This raked ceiling and perimeter walls are lined with timber veneer.

Hand-painted interiors in deep green amplifies the garden setting and the bathroom reveals itself as a golden retreat.

Tasmania Jury Citation

Garages are the strategic reserve of the single residential dwelling, a latent ‘free space’ available for diverse utilisation, once unshackled from the car. This modest project realises a self-contained flat within the tight confines of a former garage. With artfully configured built-ins; large windows; sweet and efficient kitchen and bathroom elements; and well-trained exterior ivy, this project is commendable for providing a flexible supplement to the life of the household of which it forms a part. 

So when we bought it, it was a home office at the end of the driveway somewhat incongruent with its 1902 big sister. It then became a kids play room for many years but as the kids grew up the space was abandoned.  As a family that loved to travel and adventure the opportunity to offer a special  space to travellers friends and family, separate and private to the home, really appealed.  In summer the main house, flat and cars run entirely from the power generated by its north facing solar panels.

Green which ever way you look at it.
