An efficient 4-bedroom home arranged around a calm central living space

An efficient 4-bedroom home arranged around a calm central living space. The Living/Dining anchors the plan and opens to the rest of the home. Public rooms (Balcony, Balcony, Balcony) sit at the front of the house; private rooms (Bathroom 1, Bathroom 2, Bathroom 3) are grouped away from the entry. Cooling is limited (cross-ventilation score 1/5): Sit the long facade north–south with the main openings east and west to capture prevailing breezes and avoid the low east/west sun. Limited glazing — add clerestory or high-level windows for daylight without heat gain. Electrical fit-out calls for a 40 A consumer unit with about 10 circuits; Roof can host about 40 kW of PV — sized to cover most household loads. Plan for 3 bathrooms serving roughly 7 occupants; large enough to support a soak-away; verify with a site soil test. Roof catchment could yield ~207 m³/year — size a 62 L storage tank for garden and WC use. On a minimum 391 m² plot (about 23 m × 16 m with NEMA-standard setbacks), the home covers 52% of the plot.
