A plain summary of the 2027 Part L changes as they affect windows, doors, rooflights and glazed extensions — dates, transitional rules, the numbers that moved and the ones that didn't, and what to do on live projects now.
Glass Links are a perfect way to seamlessly join two building and create a space that can be enjoyed all year round.
A glass link is a glazed connection that joins two separate structures into one usable home. It might tie a main house to a garage, an outbuilding, an annexe, or a newer wing, giving you a dry, light-filled route between spaces that were never designed to meet.
The appeal of a glass link between buildings is that it does its job almost invisibly. Slim framing and large panes keep sightlines clear, so the two original buildings stay the heroes and the connection reads as a quiet pause between them. You see the brickwork, the stone, the roofline — and you walk between them in comfort.
We’ve covered the design thinking in more detail in How a Glass Link Can Connect Two Buildings, and you can see the idea built in our Glass Link in the Yorkshire Dales and Glass Link & Office projects.
A glass link extension works particularly well on older homes because it adds space without competing with the original architecture. Rather than bolting a matching extension onto a period façade, a glazed link sits lightly against the old wall and lets it carry on being seen.
On listed and heritage properties this is often the difference between a scheme that gains consent and one that doesn’t. A reversible, clearly modern glazed connection that touches the historic fabric minimally is usually easier to justify to a conservation officer than a solid addition that imitates the original. We explain the heritage approach in Glass Link for Listed Buildings, and How a Glass Corridor Can Add Value to Your Home is worth a read if you’re weighing up the return.
Every link we build is made to measure for the two buildings it joins — survey, framing, glass specification and structural support are all worked out for that specific gap. If you’re comparing options, our wider glazing products and built projects show how the same detailing carries across extensions, corridors and entrances.
The character and condition of both buildings, so the link complements rather than competes
How the structure is supported — minimal steel or slim framing to keep glass loads safe
Thermal performance and solar control to keep the link comfortable through the seasons
Any level changes, drainage and weathering where the glass meets old masonry
Reversibility and a light touch on historic fabric for listed or conservation-area homes
How the link is used day to day — a walkway, a seating spot, or a room in its own right
It depends on the property and its location. Many glass links fall within permitted development, but listed buildings, conservation areas and larger schemes usually need full consent. We’ll talk you through the likely route for your home before any design work begins.

Part O caps the glazed area of every new home room by room, by orientation and ventilation. The moderate-risk figures for Liverpool, Manchester and the North West, what happens when a design exceeds them, and how to keep the big glass.

From 24 March 2027 every window on a new home must be calculated at its real size with every frame component included. What changes, who it catches, and how steel, aluminium and structural glass get to 1.2 W/m²K.

Most of the houses we glaze are old. Georgian terraces in Liverpool, Victorian villas in Cheshire and South Manchester, stone farmhouses in Lancashire and the Dales. Here is why structural glass tends to be the extension that gets approved on a period home, and how the old wall and the new glass are made to meet.

People planning a glass box, link or corridor usually want to know two things: how long it takes and what happens in between. This is the sequence every one of our North West projects follows, from the first site visit in Cheshire, Lancashire or Merseyside to the day the glass goes in.

The two worries every client raises about a glass room are that it will be freezing in winter and a greenhouse in summer. Both used to be true. Here is how modern structural glazing is specified so that neither is — and what we watch for on North West projects in particular.
