AD | Collaborative post Converted sheds, garden rooms, conservatories. These aren’t storage spaces anymore. UK homeowners are treating them as proper rooms, and the ones that work year-round share one thing: the right windows. Get that wrong and you’re dealing with draughts in October, condensation on the walls by December, and heating bills that don’t make sense. Window choice isn’t a finishing decision. It’s a structural one. Thermal performance, ventilation, durability: these determine whether the space is usable in February or abandoned until April.
