Healthy & Sustainable Homes
Bring natural light into dark rooms
Larger windows, skylights, light wells, glass partitions and lighter finishes that brighten dark homes.
Dark rooms need lights on all day, feel smaller and are more prone to damp. Older homes and densely built neighbourhoods often suffer most.
RennovEN finds where daylight can come from — a bigger window, a skylight, a light well, or simply a glass partition instead of a wall — and makes the change safely.
Signs you need this
- Lights on during the day

Diagnosis
Why it happens
Small openings
Older designs used small windows for security and heat.
Close neighbours
New buildings next door block light over time.
Dark finishes
Dark walls and floors absorb what little light enters.
