Ivory Bungalow

A large private residence over a ground floor, a first floor and a terrace, planned around a courtyard. Besides the family rooms — a living room of about 7.7 × 4.8 m, a master suite with its own lounge and walk-in wardrobe, a daughter's room and three further bedrooms — the house has a spa and salon, an entertainment and lounge room, an open bar and outdoor area and an open deck, all served by a lift. The architect's ceilings are detailed: coves, profile lighting, mouldings and curved battens, with concealed air-conditioning units above them. Every pipe, drain, light point and indoor and outdoor unit had to be fitted into those slab levels and ceiling heights without changing the design.

Plumbing: we laid out the ground, first and terrace floors and a cross-section, with cold water at 20 mm from a 7,000-litre domestic tank (about 1.45 m of water with a 0.30 m free board) and a booster pump, an underground-to-overhead tank pumping line fed from the corporation inlet, and hot water from a 2,000-litre storage tank with a heat pump and a return pump. Drainage: 110 mm soil pipes, 75 mm waste pipes and 40 mm basin outlets with traps, sunk slabs of 75 to 200 mm in the toilets, balconies and wash areas, 110 mm rainwater pipes and a ready-made gutter, with 150 mm sewage and storm-water lines, sewage chambers, storm chambers and gully traps taken to the existing site drains. Electrical: an electrical fixture and conduit layout, with the external services shown on separate layers — HT chamber, LT hume pipes and chambers, earthing pits and a power cable tray. Cooling: we coordinated the one-way cassette units, which are concealed in the false ceiling, and the high-wall units, and located the outdoor units, with the architect's ceiling plan, where the ceiling sits at the lintel level of 2.75 m in the foyer and rises to 3.6 m above the finished floor in the living room. The drawings went out for approval and were revised in several rounds. Slabs: before each pour we issued a sleeve and cutout layout - for the first slab in June 2025, with 600 x 300 and 1,420 x 900 mm plumbing cutouts, 100 mm sleeves through the beams and 200 mm sunk slabs or top-flush beams under the toilets, and for the second slab in July 2025, with plumbing cutouts, 150 mm sleeves in the beams and the HVAC and electrical ducts. Power and backup (March and April 2026): lighting and fans of 3.6 kW, sockets of 10.9 kW, the lift, the landscape lighting, the pumps and an 11.2 kW heat pump, and about 12 kW of air conditioning (8.6 tons on each floor) come to 50.4 kW connected and 31 kW of maximum demand at 60% diversity; at 80% the house needs 41 kW, 54.7 kVA, from standby, so an 82.5 kVA DG set is recommended, with a 5 kVA UPS holding the lighting for four hours. The water is lifted by a pair of submersible pumps, one working and one standby, at 5 cu m an hour, with a skid-mounted pressure booster pair on the terrace.
