Environmental
engineering, by hand.
With extensive experience in both structural and technological systems — electrical, water, heating, photovoltaic and solar thermal — Ibba Construction provides expert guidance on environmentally responsible design and construction. Performance is engineered into the structure from day one, not tacked on at the end.
Six systems,
engineered in.
Standard on every custom build. Specifications are tuned to climate zone, orientation and the way the home will actually be used.
Passive solar orientation
Building axis, eave depth and glazing area calibrated to the WA solar path — winter sun in, summer sun out.
Double glazing
Argon-filled low-e units on all habitable rooms — typically halving the heat loss of single-glazed windows.
Insulation
Full-perimeter insulation: walls, ceiling, suspended floors. Air-sealing detailed at every penetration.
Photovoltaic systems
Roof-mounted PV sized to cover annual self-consumption. Tier-1 panels, hybrid inverter and battery-ready.
Solar-thermal hot water
Roof-mounted thermal collectors with gas or heat-pump backup. Hot water for the household from sunlight.
Material sourcing
Premium Perth-quality materials and Italian craftsmanship — every material has a traceable origin where feasible.
From sketch
to roof line.
Selected installations from recent builds. Photovoltaic arrays, solar-thermal collectors and the everyday detailing that lets a home run efficiently for decades.
