Roof lanterns in Gosport: what is involved?
For Gosport homes and buildings we offer roof lanterns: hipped glass lanterns that lift the ceiling of orangeries and extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Roof lanterns suit rooms that need height as well as light.
We work across Hampshire, including Gosport, and in neighbouring towns such as Portsmouth and Fareham. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Rectangular, square or bespoke sizes
- Aluminium or uPVC systems
- Opening vents with electric control
- LED lighting in the plaster box
- Solar-control or self-cleaning glass
- Adds visual height to a single-storey room
- Classic look that suits period and modern homes
What to check first
- Some designs project above the roof enough to affect planning on certain houses
- Plaster-box depth affects how the lantern looks from below
Planning and building rules for Gosport
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.

Roof lanterns in Gosport: questions
Roof lantern or flat rooflight?
A lantern adds height and sky from all sides; a flat rooflight is lower-profile and cleaner from outside. Our guide compares them in detail.
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
Can a lantern go on an existing extension?
Yes, if the flat roof structure can be opened up and trimmed. We check joists and the roof build-up at survey.
Do you fit roof lanterns in Gosport?
Yes. We survey and fit roof lanterns in Gosport and across Hampshire. Send your postcode and we will offer a survey date when we reply.
Will I need planning permission in Gosport?
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.
