Flushness The Innovators in Roo ighting Roo ighting in the Conservation Environment The Conservation Roo ight® from the Roo ight Company has more sizes in different widths than any other supplier Somerset House, London The Roo ight Company supplied 40 specially-designed roo ights for Somerset House in 1997. These were exact copies of the original, bespoke roo ights dating from the turn of the century. With access to the roof being a major problem low maintenance was essential, hence the decision to specify steel roo ights with a protective coating. All the different sizes and shapes of roo ights had to be painstakingly surveyed on site with the appropriate design and dimensions drawn up and proposed to the project architect, George Goff of TGB Consult. A grey / olive colour was speciŠed to match the original Cumberland slate tiles of which most were retained. A second project for a at roof at Somerset House consisting of six 600 x 1200 mm white Plateau Roo ights is currently being completed.

Size Matters The second design consideration arising from the survey is the size of roo ights particularly on Listed buildings. Conservation OfŠcers stated that over-sizing was causing the roo ine to be dominated by roo ights. Since roo ights provide 20% more light than dormer windows, the size of the roo ight can be scaled down; sensitive positioning is also very important. The Roo ight Company is the only roo ight provider to offer 8 small and narrow roo ights in the standard range. Results of a recent survey conducted with 70 Conservation OfŠcers highlight the fact that there is one overriding criterion for the desired appearance of conservation-style roo ights. That is that they should be as ush with the roof as possible. The survey also indicates that Conservation OfŠcers are concerned that some ‘conservation roo ights’ do not adhere to this and present the glazing several centimetres above the level of the roof. The Roo ight Company helps to ensure ush installation by producing a low proŠle design and by including ush slate details in our installation manual and on our website. The Conservation Roo ight® developed by architect Peter King has ne lines and lies ush to replicate the cast-iron model Built in 1839 the Roundhouse at the Grade II listed Derby Railway Works has been restored and transformed for Derby Colleges by Maber Architects and contractors Bowmer and Kirkland. The roof posed the largest challenge and consequently consultation from the Roo ight Company was sought both because of its poor state and because it offered one of the few opportunities to improve the thermal performance. Part of the reconstruction of the roof included the reinstatement of a circle of 48 trapezoidal roo ights, of which 36 had to open remotely using electric actuators. These roo ights needed to be 2.3m long and follow the line of the roof hip, but with straight bars. ‘There was a limited number of companies that could do that span and make them open,’ said Project Architect Ian Harris. These special versions of the Conservation Roo ight® from the Roo ight Company provided the ventilation and thermal requirements, and, with their slender frames, matched the appearance of the roo ights in the original photographs. The scheme as a whole has already featured in English Heritage's recent “Constructive Conservation” book as one of 20 exemplar projects nationwide.
