Walk on glass floor in Wandsworth
In England, Approved Document L sets a limiting U-value of 2.2 W/m²K for rooflights, calculated in the horizontal position. Frameless glass roofs and fixed rooflights are usually specified with low-E double or triple glazed units, and their declared performance should be checked against this before ordering.
The price of a glass roof or walk-on panel depends on glass size and make-up, the number of laminated layers, coatings, support beams or framing, structural design, lifting equipment and access. Bespoke shapes and very large panels cost more. See the guide prices for typical ranges.
Glass roofs are heavy and the units are large, so installation often needs cranes, glass lifting robots or vacuum lifters, and sometimes road or pavement access arrangements. Access is planned at survey, because it can influence the maximum panel size and the installation day.
In England, Approved Document L limits how much of an extension can be glazed when the simple standard route is used. Large glass roofs often go beyond that limit, so energy calculations are usually needed to show the extension still complies, and building control checks them.
What a typical job includes
- Weather sealing of joints, edges and upstands
- Glass specification with laminated make-up and coatings
- Coordination with engineers or builders where required
- Site survey and structural assessment of supports

- SW11, SW12, SW15, SW17, SW18 and the surrounding area, including Putney, Fulham and Chelsea
- Coast
- Wandsworth is well inland, around 39 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Wandsworth the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 hours in midsummer. Overhead glass admits far more daylight than vertical glazing, especially in summer when the sun is high. South-facing glass roofs usually need solar-control coatings or fritting, while north-facing roofs can use clearer low-E glass to maximise winter light.
- Access and setting
- City glass roofs often need cranes or lifting robots, so road or pavement licences, parking suspensions and access over neighbouring property may be needed. Side returns usually sit on a boundary, so fire performance and neighbour matters should be checked early.
- Rules in England
- Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

Listed buildings in England need listed building consent for most changes to historic windows or glass, and conservation areas can restrict changes visible from the street. Speak to the council's conservation officer before ordering.

Glass Roofs in Wandsworth: questions
What guarantee comes with a glass roof?
Manufacturer guarantees apply to the glass units, coatings and any framing or fixings, and the terms are confirmed in writing. Supports built by others are covered by their own builder's terms. Guarantee terms for our installation are set out in writing with your quote, so you know what is covered and who is responsible before work begins.
Do I need planning permission for a glass roof extension?
It depends on the extension and the property. Some single-storey extensions on houses fall under permitted development, while others need planning permission. Flats, listed buildings and homes in conservation areas or under Article 4 directions have additional controls. Check with your council or an architect early, before the glass is ordered.
Does a glass roof need building regulations approval?
Yes. A new glass roof, frameless rooflight or walk-on panel is building work that normally needs approval through building control, covering structure, energy performance and fire performance near a boundary. Highly glazed extensions often need energy calculations to show compliance. The rules differ between England, Wales, Scotland and Northern Ireland, and we explain the route for your project.
How much does a glass roof cost?
The cost of a glass roof depends on the area of glass, the size of each unit, the glass make-up and coatings, the support beams or framing, the structural design and the access for lifting. Walk-on and very large panes cost more because of their thickness. See the guide prices for typical ranges; the written quote fixes the price.
