Central London
Fixed Flat Rooflight

This London rooflight case study concerns a fashional apartment in the very heart of the city.

London property market is on average eight times the national average and central London properties are very much reserved for the wealthy. The central suburbs have grown in popularity and this has lead to many house conversions to studio flats and luxury apartments.

Apartment living in the central suburbs of London areas is very much in vogue now with the professionals and with many over the half a million pound mark – making good use of limited space can be a challenge.

However apartments on the top level of a building give ample opportunities to open up the roof space to allow extra light coming into the property amplifying the perceived space considerably. This is exactly what one architect did for a property development in the Battersea area, and why we wanted to make it a landmark London rooflight case study.

The property is an apartment in a converted Victorian terraced property with one bedroom, shower room and open plan kitchen. To the outside there is a large seating area overlooking the views of Battersea.

The challenge

The project involved putting a fixed flat roof window over the kitchen area so that it allowed the light across the whole of the open plan living space giving a lighter and roomier feel. The minimal look of the roof light enhanced the architectural finish of the apartment providing a great source of natural light, as well as ample night time star gazing opportunities.

Performance and aesthetics

Paul Thomas comments on the conversion using Roof Maker rooflights “Being very aware of environmental and fabric performance, we were impressed by the triple glazed units, measures to reduce risk of overheating, together with the overall Ug-values being achieved.”

As shown in this London rooflight case study, environmental performance is a key measure used in Roof Maker rooflights with industry leading U values* and 30 year life expectancy of products covered by a 20-year unit seal warranty. This why many architects and interior designers look toward our products when specifying for clients.We can currently achieve a Ug-value of 0.6W/m2k for Triple and as low as 0.3W/m2k for Quadruple glazing using phenolic foam in our Flat slide open rooflights!

* A U value is a measure of heat loss. It is expressed in W/m2k, and shows the amount of heat lost in watts (W) per square metre of material when the temperature (k) outside is at least one degree lower. The lower the Ug-value, the better the insulation provided by the material.
