Conservation
The Bygone Collection is dedicated to creating beautiful sash windows that authentically capture the spirit of three hundred years of sash window history.
A window made from PVC-U may seem to fly in the face in the face of that ambition, however today more and more conservation officers and planning inspectors are being convinced by Bygone sash windows. Conservation officers have a duty to retain the character of buildings, so it is entirely natural that they want to keep everything as it is.
When most hear the words PVC - U They instinctively think of the thousands of casement windows that many owners had installed when double glazing first became popular in the early 1980’s. Many buildings have been disfigured by inappropriate replacements, that have damaged the charm and character of the property.
What conservation officers do demand is authentic detail. Not imitation, but truly authentic detailing and features. They want to retain the character of a property, so they simply will not entertain shiny white plastic, out of character tilt & turn windows or mock sash casement styled windows. Bygone window is so authentic that conservation officers and planners are increasingly being won over by them.
An Inspector from the Office of the Deputy Prime Minister said,
“The window (Bygone Collection) appears to replicate a traditional sliding sash window very closely. The effect is so convincing that it is difficult to differentiate between the two (timber original) even at close quarters.” Unlike many other UPVC-U imitations of sash windows, which pay only superficial attention to traditional detailing, the mouldings on the frame of the unit, which also extends to the central glazing bars, appears most authentic”.
So authentic is the effect that a senior planner (building his own house) standing just feet away from a Bygone sash window actually said, “I don’t want timber - I want a PVC-U sash window”, he couldn’t believe his eyes seeing our white acrylic timber finish. Bygone sash windows have been installed in conservation areas, national parks, a World Heritage site in Conwy, buildings with an article 4 directive and even grade 2 listed buildings.
As the Bygone Collection is available in wood and PVC-U we are ideally placed to help with any conservation questions you may have. It is worth noting that you do not require planning permission within a conservation area unless your property is subject to an Article 4 directive or the property is commercial or contains multiple dwellings.
