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, Kitchen) sit at the front of the house; private rooms (Bathroom 1, Bathroom 2, Bathroom 3) are grouped away from the entry. The footprint is near-square — a compact plan that fits a tight plot and keeps plumbing walls together to reduce build cost. Cooling is fair (cross-ventilation score 2/5): Sit the long facade north–south with the main openings east and west to capture prevailing breezes and avoid the low east/west sun. Glazing is balanced — pair with 600–900 mm eaves for shading. Electrical fit-out calls for a 40 A consumer unit with about 11 circuits; Roof can host about 49 kW of PV — sized to cover most household loads. Plan for 4 bathrooms serving roughly 7 occupants; sized for either septic or municipal sewer — choose by plot location. Roof catchment could yield ~250 m³/year — size a 75 L storage tank for garden and WC use. On a minimum 456 m² plot (about 21 m × 21 m with NEMA-standard setbacks), the home covers 44% of the plot.
