How we approach glass links & glass box roofs in Keswick
Our glass links & glass box roofs service in Keswick 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.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. Typical uses for glass links & glass box roofs include joining a period house to a new extension or annexe.
From Keswick to Penrith, Workington and Whitehaven, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose

Planning and building rules for Keswick
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. 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.
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
Read the planning permission guide before you commit to a design.

Glass links & glass box roofs in Keswick: questions
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.
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.
How long does a link take?
Design and manufacture are the long part. Fitting is often two to five days.

Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
