Glazing Vision was recently chosen to supply its sliding-over fixed rooflight for the construction of a three-storey extension of a semi-detached property in Regent’s Mews, London.
The sliding-over fixed rooflight was installed above the stairwell, chosen to provide maximum natural light in the dark area, along with four additional fixed rooflights to brighten the new living space and provide a source of ventilation.
Situated in St John’s Wood Conservation area, where restrictions on the character and appearance of all buildings are strictly applied, it was key for Robinson Leigh Architects to design all new work to match existing original work. Therefore, Robinson Leigh suggested a flat-topped mansard roof that would not add height above the general roof level of the neighbouring properties in Regent’s Mews.
In addition, the pitch of the northwest slope of the mansard roof was adjusted to a 70 degree angle in order to reduce its prominence in the views from the villas of Langford Place, tot he rear of the property. A second flat roof, which adjoined the house was removed, and Robinson Leigh extended the mansard roof to the parapet, giving the client more internal space and eliminating any overlooking issues.
However, the structure of roof meant that there were various ‘dark zones’ in the interior of the new storey. Robinson Leigh’s solution was a glazing arrangement on the flat-top of the mansard roof, comprising four large fixed rooflights and a sliding over fixed rooflight from Glazing Vision, providing plenty of daylight that bounces off the hardwood timber.
Glazing Vision’s sliding over fixed rooflight was to inhabit the space immediately above the stairwell, which had also been lined in timber to subtly link the top floor with the ground floor and to help draw the eye upwards. Timber frames had also been used on the windows. As with the other four rooflights, Glazing Vision’s sliding over fixed rooflight needed to be made to a bespoke size. The sliding over fixed rooflight was supplied in two sections, with an overall span of 2400mm and a width of 2240mm.
The rooflight was ideal for aesthetics, finished in pure white on the inside and finished in slate grey on the outside to blend with the Welsh slate roof tiles.
Finally, the Glazing Vision rooflight slides side-to-side rather than up and down and is electronically controlled at the touch of a button, retracting the sliding section over the fixed section of glazing, providing a 50% clear opening. Therefore, the rooflight provides the client with maximum natural daylight as well as superior air quality within the top floor.
