Glass links & glass box roofs for March: the essentials
Our glass links & glass box roofs service in March 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.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. Typical uses for glass links & glass box roofs include joining a period house to a new extension or annexe.
Jobs in March are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Planning, building control and March
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.
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.

Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.

Often, yes — and listed building consent if either building is listed. We can provide drawings and product data for your application.
