Roof Lanterns in Alton
Korniche roof lanterns are a popular addition to kitchen extensions on Alton’s Georgian and period properties, flooding flat-roof spaces with natural light from above. Within the Alton Conservation Area, roof lanterns are generally acceptable on single-storey rear extensions as permitted development, provided they do not extend more than 150mm above the existing roof plane. The patented snap-fit aluminium frame holds 30% more glass than traditional lanterns with no tie bars needed up to 3m x 1.5m, and the integrated hidden drainage system handles the heaviest rainfall across the GU34 postcode. Self-cleaning and solar-control glass options are particularly popular on south-facing Alton kitchen extensions. Vitrum Solutions surveys Alton homes throughout the area, including near Jane Austen's House Museum (nearby Chawton) and Watercress Line. Properties inside the Alton Conservation Area need East Hampshire District Council approval for replacement glazing. We handle that liaison as part of every quote.
