A glazed roof extension to Grade II listed Victorian house in AONB with views overlooking the historic harbour of Lyme Regis and the Cobb. Extensive coastal views can be enjoyed throughout the seasons through the new frameless Oriel seating glass window which forms a key social space within the new double height structural glass extension boasting sea views through a double height glazed link that opens out via ultra slims sliding glass doors with flush threshold detail.

Location
rak architecture was commissioned to design a cluster of glazed extensions that would not take from the character of the original attractive Grade II listed building in an Area of Outstanding Natural Beauty (AONB) within Lyme Regis, but to frame stunning views through an Oriel frameless picture window as far as the Golden Cap to the east with a double height glazed link and ultra slim framed sliding glass doors subserviently connecting the old with the new.
The attractive Grade II listed building with its unique overlapping slate tiled façade, symbolic of fish scales, needed the replacement extension to include a frameless glazed link to the brick building with a mono pitched roof, drawing inspiration from a discovered 1950s postcard showing that a much earlier outbuilding with a similar roofline and chimney had once existed.
The new addition to the original house is intentionally in contrast to the original Grade II listed building, and smaller in scale. Combining black brick and slate cladding, an oversized frameless glass oriel picture box window is a clever addition, representing a modern interpretation of a Victorian box bay window seen in the original old house.
The structural glass link sees a much smaller scale extension to the original build.
The glazed roof exposes the reclaimed Welsh slate overlapping fish scale tiles of the old building and the new extension, of which a total of 3500 were used.
The steel roof structure of the extension was designed to appear light and minimal. The roof trusses are globally aligned to match exactly with the glazing bars of the ultra slim framed sliding glass doors.
Marine grade glazing was installed to enable the building to perform efficiently no matter what the weather.

Double-glazing thermally broken glass with solar control coatings was installed throughout. Internal temperatures in the summer are regulated by opening the full height slim sliders, three casement windows and stable doors as required to create ventilative cooling as there is nearly always a cool breeze on the coast.
One key benefit of this structural glass link is that during winter months there is enough solar gain to create a comfortable living environment throughout the day, supplemented in the early morning and evening by underfloor heating and a woodburning stove.
The full height ultra wide slim sliding glass doors open on to a terrace via a flush threshold with integral drain to create a seamless transition from inside to outside, and an extended living space in the summer.
The extensive use of glass to the rear elevation makes the most of the far-reaching sea views. The deep Oriel window seat places the sitter looking across the bay towards Golden Cap which is the highest coastal hill in Dorset.
The proud owner shared "The height of the glass pitched roof and the sheer amount of light make the space feel more expansive to live in.
"Sitting in the Oriel window projects you into the garden and amongst the plants. It’s going to be a favourite reading spot!"
