Ultra-Slim Sliding Door System for a Luxury Cotswolds Extension
DESCRIPTION
This contemporary Cotswolds extension showcases the dramatic impact of large-scale architectural glazing, featuring a 6.5-metre-wide by 3-metre-high, three-panel frameless sliding door system engineered for maximum transparency. With each panel weighing 260kg, specialist lifting equipment was required to guide the glass into place with precision. The client’s priority was to achieve the greatest possible glazed area, which we delivered using our ultra-slim 17mm sightlines and a beautifully integrated arrangement of sliding doors. The result is a seamless connection between indoors and outdoors, defined by clean lines, uninterrupted views, and outstanding craftsmanship.
