Loft Conversions – Various Types

Any homeowner who wants to create some additional living space in his/her property has an option of converting his existing roof space into a habitable space. Loft conversion in any property is possible if there is ample roof space available in the attic. The process involves a survey before planning a loft conversion to see what kind of roof property has and what structural changes it needs to make it habitable. The loft conversions are generally considered to be a permitted development if it remains within the specified limits set by each local council. However, if it extends beyond the specified limits then one may need to apply for planning permission. Some of the FAQ’s are as follows:

Do I need building regulations approval for loft conversion?

Irrespective of the requirement of planning permissions you do need building regulations approval at various stages of work, a completion certificate and the final inspection.

Do I need to notify my neighbours?

In a semi-detached or a mid-terraced house you need to notify your neighbour about the works according to party wall act of 1997.

Do I need feasibility study for loft conversion?

The process of loft conversion starts with the feasibility study to check following:

    • Does the roof have enough space available for headroom?
    • What’s the existing pitch of the roof to check if roof needs  re-designing to accommodate roof dormers etc.?
    • What is the composition of the existing roof?
    • Does existing roof have any water tanks or chimney stacks? 

What are the various types of loft conversions?

  • Dormer loft conversion

This type of conversion increases the headroom and adds to the useable floor space. Staircase fitting gets more simplified due to additional headroom being created. The dormer loft conversion costs more as compared to the roof light loft conversion.Dormer attic conversion on a mid-terraced property.


  • Roof light loft conversion

This kind of conversion is built within the existing frame of the roof with minor structural reinforcements. This type of conversion is cost effective and takes lesser time to complete. It involves a couple of roof lights, a staircase, roof and floor insulation, electrics, lighting and heating.

  •  Hip to gable loft conversion

It is created by converting the hip of the roof into a gable end to make it visually more appealing when looking from the sides. Adding a rear-facing dormer to the roof can create some additional space. The addition of dormer also eases the fitting of staircase due to added floor space and headroom.

  • Mansard loft conversion

This is created when the walls are raised on the either side of the dormer loft creation space. It needs planning permission in place before its constructed and takes longer construction time. The backside wall slopes inward at an angle of 72 degrees. Windows are generally housed between small dormers. This type of conversion can add some real value added space to the existing propert
