Two stone barns joined by a fully glazed link

Two stone barns, a narrow gap between them, and a client who did not want to give up a single degree of the view. This project connects the two buildings with a fully glazed link: slim anthracite aluminium framing, glass from floor to head on both elevations, and as little structure as we could get away with.
The obvious answer was to close the gap in matching stone. It would have been simpler, and it would have been wrong — a dark internal corridor, and two characterful buildings collapsed into one long mass. The brief was to join the barns without changing how either one reads from the garden.
So the link is glazed on both faces. From outside it barely registers: a clean dark reveal between two stone gables, with a low capped roof tucked in beneath the eaves of both buildings so nothing competes with the original rooflines. You still see two barns. The connection between them all but disappears.
On the garden elevation, a glazed door set with full-height side screens turns the link into the everyday way in and out. The frames are finished in anthracite grey to pick up the rainwater goods and window frames already on the property, so the new work sits alongside the old rather than announcing itself.
Inside is where it pays off. You stand between two rough stone walls with clear glass at either end, looking straight out over sandstone paving, lavender beds and the greenhouse to open fields beyond. An oak sleeper bench sits in the opening. What was dead space between two buildings is now the brightest spot on the property — and the place people stop on their way through.
Thermally broken aluminium profiles in a powder-coated anthracite finish, with double-glazed units throughout. Slim sightlines keep the frame to a minimum so the glass, the stone and the view do the work. Every opening was surveyed and made to measure against the existing stonework — on a barn conversion nothing is square, and the glazing has to follow the building rather than the other way round.

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.
