Key Design Features & Influences

3 bed, 2 living, 2 bath, 2 outdoor entertaining areas

470m² slightly sloped block with north to the diagonal

Double carport

Tailored to the tricky block to maximise solar passive gain over winter and ensure adequate shading over summer. Computer simulations used to optimise the size and position of windows and shading devices specifically for this block, climate and design.

Designed to the client's brief and budget using our Light House Modular approach

 

Sustainability Features

8.2 stars (predicted to require < 50% of the energy needed to heat and cool a 6 star design)

Air tightness of 6.8 air changes per hour at 50 Pascals – 3 to 4 times better than most Canberra homes; achieved using standard timber-frame construction methods ie. no special air barrier membrane was used, instead ceiling penetrations were minimised and attention to detail was used when lining the house with plasterboard.

Thoroughly insulated building envelope – R5 to the ceilings, R2.5 to the external walls, R1.5 to internal walls, R1 to the slab.

Vapour permeable membrane used to wrap the outside of the timber frame in the walls and roof – this taped membrane reduces air movement across the insulation and allows any water vapour in the wall and roof spaces to escape.

Sanden hot water heat pump.
