Bespoke & shaped rooflights in Barnes: what is involved?
Thinking about bespoke & shaped rooflights in Barnes? The short answer: triangular, angled, curved and multi-pane rooflights made to measure. The longer answer depends on your roof, which is why we survey before we price.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Think of bespoke & shaped rooflights for openings that standard sizes do not fit.
We work across Greater London, including Barnes, and in neighbouring towns such as Chiswick and Putney. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Concealed or slim frames
- Triangular and trapezoid panes
- Corner and wrap-around glazing
- Multi-pane butt-jointed runs
- Sloped or monopitch rooflights
- Drawing sign-off before order
- Corner, slope and multi-pane runs
What to check first
- Precise survey and template may be needed
- Large panes need a lifting plan
Do you need permission in Barnes?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.

Some can. Shaped glass is usually fixed, combined with a standard opening unit elsewhere.

Most straight-edged shapes can be made in glass, within the manufacturer's size and angle limits. Curved glass is possible but specialist.

Not if detailed properly — corners and junctions just need more care.
