Glass links & glass box roofs for Borehamwood: the essentials
Our glass links & glass box roofs service in Borehamwood covers frameless glass links joining old and new buildings. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. In Borehamwood, as anywhere, glass links & glass box roofs are the usual choice for listed and period buildings where the old wall should stay visible.
Neighbouring towns include Barnet (5 km) and Bushey (6 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Borehamwood
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about glass links & glass box roofs in Borehamwood
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
Do glass links need planning permission?
Often, yes — and listed building consent if either building is listed. We can provide drawings and product data for your application.
Can a glass link be warm enough to use all year?
With insulated glass units, solar control and good detailing, yes — though it will always be brighter and more exposed to temperature swings than a solid room.
Do I need to be at home for the survey in Borehamwood?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Borehamwood?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
