Bring natural light where it matters most.
At Bigness Group, we design and install rooflights and skylights that flood interiors with daylight, improve ventilation, and add architectural value to every property.
Our glazing experts create custom rooflight solutions for homes, extensions, and commercial buildings across London — combining style, safety, and superior insulation.
From flat glass rooflights to pitched skylights and walk-on systems, we make light a feature of your architecture.
Designed for Light and Performance
Natural light transforms how spaces feel — open, calm, and alive.
Our rooflight systems are built for both beauty and efficiency, using thermally broken aluminium frames and high-performance glazing.
Each unit is custom-sized and precision-installed for perfect alignment, waterproofing, and durability.
Whether it’s a minimalist flat glass skylight or a statement roof lantern, we make sure light works for your design and energy goals.
