When land is expensive and the view is worth capturing, building up instead of out makes perfect sense. A three-storey house is no longer just for dense urban lots; it’s a strategic choice for maximizing space, privacy, and even passive cooling. But designing a successful tri-level home requires more than stacking rooms—it demands a thoughtful vertical flow. Why Choose a 3-Storey Design? 1. Maximizing a Narrow Footprint On a standard 150–300 sqm lot, a three-storey design can easily yield 250–450 sqm of living space while leaving room for a garden or parking.

The third storey becomes your penthouse: a master suite or lounge that rises above neighbouring rooftops, trees, and street noise.
