Extending upwards

Making the most of useable space in your building can yield big rewards, in London the presence of a roof terrace or balcony typically adds 12% to the value of a property, rising to as much as 25% in coveted Chelsea.

Roof terraces and gardens are often more private and less likely to be overlooked – they can offer outstanding views of the city where space is at a premium.


There are several options which will allow access to the roof from simple maintenance hatches such as the Skyhatch, larger hinged access units or sliding glass box rooflights such as the box rooflight featured on this residential property.

These types of unit really are more than just a rooflight and box rooflights are often the preferred option due to the physical structure removing the requirement for balustrades.

Roof Terrace access

Occasionally you may encounter planning issues in some cases relating to potential increase to the building height, particularly where this will exceed any existing balustrading or parapet wall.

This is most likely to restrict the use of box rooflights but other options such as the Skydoor hinged access rooflight are more likely to be accepted as an alternative option due to its lower profile when closed
