A popular way to increase habitable space within your semi-detached home, there are a number of options available when you're looking to add a loft conversion to your semi-detached property.  With all construction projects there are factors that can determine the type of loft conversion you go for; budget, required space and potential consent to build are a few.

So what are the available loft conversion options when converting a loft within a semi-detached property?

Velux / roof light conversion

The simple loft conversion choice.  Velux/roof light conversions offer a great way to gain light into your loft conversion without the need to undertake major structural changes. Roof lights added to the rear of the property generally are allowed within permitted development; however, should you wish to install windows to the front of the property permission will need to be obtained.  

As structurally there is minimal change to the loft, it can be challenging to locate the stairs and meet Building Regulations head height requirements.  It is worth considering how you would utilise the loft space as the middle of the loft is often where the stairs have to be placed as this is where the greatest head height is. Well suited to areas where permission is not granted for a dormer loft conversion, this is the most cost-effective option as it involves minimal alteration to the structure and planning is seldom required.  

Dormer loft conversion

A dormer loft conversion is a structural extension which projects vertically from the plane of a sloping roof.  Dormer windows are added creating additional floor space and headroom within the property. The most popular type of dormer conversion in the UK is a:

  • Flat roof dormer conversion. This offers the largest amount of added internal space and involves extending the previously sloped roof so that it is flat – adding both floor and headroom. This conversion will provide you with significantly more space, and is a suitable option for semi-detached homes. Generally, it falls under permitted development rights as an extension, but you may need planning permission if the conversion will involve windows that overlook your neighbour’s property.
  • Gable fronted dormer or “dog-house dormer” is a more attractive option which consists of a gable wall extension built up to the existing ridgeline, and a new roof section built outwards to the new gable end.

Hip to gable loft conversion

A hip to gable extension is a viable option for semi-detached houses with one hip-ended roof. Replacing the hipped roof with a vertical wall increases the space and headroom within your loft, making it more suitable to be converted into an additional living space.

 

When undertaking any building work it would be advisable to inform neighbours of any potential disruption, especially as a semi-detached property shares an adjoining wall.  It is also worth checking with the local planning authority to ensure there will be no issues with your home improvement plans.
