How much does a loft conversion cost?
Having your loft converted is a great way to add living space to your home without the stress and upheaval of moving. It can also be a significantly cheaper option and all that extra space you’ve created will add desirability and market value to your property, as much as 23% according to Nationwide Building Society. For these reasons, many expanding families and property developers alike now see it as a smart investment choice, so what exactly is the cost of a loft conversion?
There isn’t usually a straightforward answer to that question because loft conversion costs will vary significantly in relation to your specific requirements. Prices can start from as low as £10,000, at a very basic level, and reach upwards of £50,000 depending on the size and complexity.
Some typical factors to consider when working out your loft conversion cost will include:
- Potential work needed to strengthen the loft to make it fit for purpose
- Adding roof or dormer windows
- Plumbing of sinks, toilets, baths and showers if you are considering a bathroom or an ensuite
- Heating installation
- The level of extravagance you might wish to use in the finishing and decorating
- Staircase and landing
The type of loft conversion you choose will also have a big effect on the total cost. These are just a few examples:
Dormer Loft Conversion – This involves extending outward, in a box shape, from the side or back of a sloping roof. Internally, a dormer has a horizontal ceiling and vertical walls which is great for maximising space. Dormers are very popular and are generally considered to be the least expensive option, depending on the amount and style of dormers you add. A rough guide price for a dormer loft conversion would be between £19,000 – £27,000. Surprisingly, most dormers (but not all) won’t actually require any planning permission.
Hip to Gable Loft Conversion – Houses with a hip roof generally have lofts with a small amount of internal volume therefore the most suitable solution, to give the largest amount of space, is often a hip to gable. This involves converting the sloped side of the roof (the hip) into a flat, gable end. Planning permission is more likely to be required here because you are essentially changing the contour or the roof. The cost of a hip to gable loft conversion could range from between £30,000 – £35,000.
Mansard Loft Conversion – These are a more expensive option but will create the maximum amount of possible space. A mansard has a flat roof and then the entire back slope is altered to a steeper gradient – typically around 72 degrees. Significant work will need to be done on the structure so planning permission is almost always required. Mansard Loft Conversions can cost anything from £30,000 – £40,000.
