Glass links & glass box roofs for Chiswick: the essentials
Our glass links & glass box roofs service in Chiswick 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.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Glass links & glass box roofs suit listed and period buildings where the old wall should stay visible.
Neighbouring towns include Hammersmith (2 km) and Acton (2 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Chiswick
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Glass links & glass box roofs in Chiswick: questions
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.
How is the glass joined to the old wall?
Usually by a slim channel or flashing set into the masonry, sealed and weathered so the old wall can move without cracking the glass seal.
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
Do I need to be at home for the survey in Chiswick?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Chiswick free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
