Granny Flat in Kelmscott

Kelmscott Residence and Granny Flat

This house and granny flat development is located on a rear lot subdivision to a corner block allowing for street frontage. This street is in a heritage listed area of Kelmscott and the design needed to be sympathetic with the streetscape. This included verandas facing the street and resulted in a cottage feel to the design, which suited the owner’s ideas.

The main house is a compact residence for a single person with accommodation for guests, an open plan living area with a north facing small courtyard and a single car garage. The layout includes an open plan kitchen / dining / living area,
1 bedroom and ensuite, a guest bedroom, a compact second bathroom / toilet, storage room, single garage and laundry.

The granny flat is linked to the main residence via a single carport and store. This granny flat has 1 bedroom, a combined bathroom / laundry and an open plan kitchen / dining / living area.

Construction is concrete slab on ground, structurally insulated wall panels, and a timber frame roof with metal sheeting. The structurally insulated wall panels or SIPS walls are panels of polystyrene board between 2 sheets of fibre cement sheeting. This system allows for a quick and efficient build with minimum waste and only one trade on site to erect them. They offer a high level of insulation. In this case R3.57 for the 150mm thick external walls and R2.5 for the 86mm internal walls.
