The project was technically challenging particularly with the necessary conservation of the remaining fabric of the castle. As well as being Grade II Listed the site was designated as a Scheduled Ancient Monument in 1994 and was officially a Building at Risk. Foundations, walls, lintels and roofs required to buttress and tie the remnants together were sensitively repaired and strengthened. Inside the property high quality joinery and finishes were installed and exposed brickwork walls help distinguish the new from the old.
Upon completion the project was considered to be ground-breaking in the way that it has sensitively stitched together the ancient ruins with modern accommodation, and it is for this reason that Astley Castle awarded the Stirling Prize for Architecture. The castle is now one of the Landmark Trust’s most popular properties and has featured extensively in numerous publications and broadcast media.
