You can convert your loft space by the use of either Velux and/or dormer windows dependant on the space you have available.
Velux windows lay flush against the pitch of your roof and are a great way of enhancing the use of natural light. Using Velux windows hardly ever requires the need for Planning Permission and can be undertaken on a Building Notice with the local authority.
Dormer windows come in many shapes and sizes. They are an extension to your roof and are an ideal way of increasing the head height to a room or stairwell. Dormer conversions may need Planning Permission but this is dependent on whether or not the dormer windows overlook a Public Highway or Footpath.
