This ambitious project involved the complete replacement of twenty-two sash and case windows across four floors of a magnificent Georgian townhouse in Edinburgh's New Town. The property, which dates from the early 19th century, is B-listed — requiring the highest standards of craftsmanship and meticulous attention to historical accuracy.
The project began with a comprehensive survey and detailed consultation with Historic Environment Scotland and the City of Edinburgh Council's planning department. We prepared a full specification document including scaled drawings, glazing bar profiles, and timber sections to demonstrate that our replacement windows would faithfully replicate every detail of the originals. Listed building consent was granted on the basis of our detailed proposals.
Manufacturing twenty-two bespoke windows of varying sizes, including the impressive full-height drawing room windows on the first floor, required careful planning and coordination. Our workshop team produced each window to exact specifications. The astragal bar patterns were meticulously replicated from the surviving originals, with traditional putty-line detailing on the exterior.
Installation was carried out over eight weeks, with scaffolding erected in two phases to manage the four-storey height. Our fitting team worked methodically floor by floor, ensuring each window was perfectly plumb, level, and operational before moving on. The project was completed on schedule and within budget, delivering a building that now meets modern performance standards while looking exactly as its original Georgian architect intended.
This project exemplifies our capability to handle large-scale, complex window replacements in the most sensitive conservation settings. The combination of traditional craftsmanship, double glazing, and rigorous project management delivered an outstanding result that the owner, the conservation authorities, and our team are all proud of.
