Extension v. Loft Conversion: The Pros and Cons

Creating additional space in your existing home is a great way to increase the property’s value without the cost and stress of a home move. Both loft conversions and extensions are popular choices.

As well as the costs of building, you will also need to consider architect and structural engineer fees, party wall agreements, and planning permission costs

Extension or Loft Conversion?

A loft conversion makes use of roof space. A loft conversion can be cheaper than an extension, whilst still adding up to a 21% increase in value to your home. The process of completing a loft conversion is generally faster and less disruptive and also ensures that there is no loss of garden space.

Space may be restricted or design options limited due to the existing roof structure. Sloping ceilings as well as joists and beams may make the layout difficult to work with and lacking in practicality. Some loft conversions will also need planning permission.

The case for building an extension instead

An extension adds to your living space in a way that is completely customisable and practical. You can build outwards, sideways or off an existing room. Extensions can be 1 or 2 storeys high, meaning huge potential for increased space, as well as adding significant value.

However, extensions can eat into your garden and outdoor space, as well as being significantly more costly than a loft conversion. There are also likely to be more constraints in terms of the planning permission required, which adds to the cost and timeline.
