Cox Architects were quick to establish the benefits of extending upwards and the rewards that could be gained from doing so in this 700 ft² roof extension and complete remodelling of a four storey mid-terrace property in West London.

Key to the project was to bring through an abundance of natural daylight, despite the enclosed element of this terraced property. Alongside opening the roof-top terrace, allowing it to be utilised as an outdoor living space.

Cox Architects considered a few options for the best way to access the terrace, firstly looking into a sliding box rooflight but given the costs was ruled out. Secondly, a flat sliding over fixed rooflight was considered, however due to its qualities as a ventilation rooflight, rather than an access product, it did not allow the necessary headroom from the stairs below.

Finally, and after detailed discussions with Glazing Vision, the Skydoor hinged access rooflight was suggested as it was able to provide the correct size opening, good thermal performance and easy operation required, giving physical access to the roof terrace above whilst flooding the lower levels of the flat with natural daylight.

By unlocking the additional space on to this well sought after property in West London, the developer has successfully added an ‘extra room’ where the residents can enjoy outside living all year round, and entertain their friends – all at the touch of a button.

When managing a complex project, there is often some concerns regarding the risks involved. However, working alongside Glazing Vision helped to ease the concerns for Cox Architects and the property developer, Sarah Wain Property Developer.
