Victorian semi, Didsbury

Ellie (34, structural engineer) and Marcus (35, restaurant manager) bought their 1897 red-brick semi on a tree-lined Didsbury street where every house still keeps its original glazing pattern — and where the conservation area means the council expects it to stay that way. The purchase survey was blunter: eight openings of rotten softwood replacements, single-glazed, painted shut. The brief from the conservation officer was like-for-like sightlines in timber; the brief from Ellie, who calculates load paths for a living, was that nobody was going to eyeball eight openings on a house where no two are quite alike.

They booked the £249 measuring visit: every opening measured professionally, the fit guaranteed. Eight conservation slimline sashes in white hardwood came back as production drawings within the week — including the bay, where two openings that "looked identical" were 18mm different. Nothing was made until the drawings were approved; eight weeks later the sashes arrived on one consignment, kerbside. Their fitter had the lot in over a long weekend, every window first time, no packers, no planing.

From the pavement the house reads as it does in old photographs of the street — same slim bars, same proportions. From inside, the difference is the quiet: the through-road traffic two streets over has dropped to a murmur.
