As you know that most of such projects allowed under permitted development rights. It means that you do not need to apply for planning permission. Furthermore, you do not need to sacrifice the garden area to get some space you need.
Loft Extension Cost in 2021
The cost can vary depending on the size of the loft. Sometimes, it requires you to make alterations in the roof and floor for staircase access. Furthermore, it depends on the area you live in the country.
To break down loft extension cost, you need to choose a type:
To create a simple room in the loft, you need skylights, insulation, eclectics, heating, and floor reinforcement. The cost of such conversion starts from £15,000.
However, in a dormer loft extension, you need all the above things plus a dormer window. If you are looking for some functionality and some basic look for your loft then this option is for you. You can also consider this extension if there is not enough head heigh or floor space. This type of conversion will cost you around £20,000 for a basic build. However, if you want some advanced finish to your loft then you can expect to pay £35,000 upwards.
Another type is the mansard loft extension which can cost you between £35,000 and £45,000upwards. On the other hand, if you have a pitched roof then we will recommend you hip-to-gable extension which can cost you around £30,000 upwards.
There are also ready-made loft conversions available. It means that all the construction work is done off-site and then craned into position. It dramatically reduces the cost of labour and bad weather conditions do not affect such builds. You can expect to pay around £55,000 for this kind of extension.
In some cases, the existing roof is not suitable for conversion and hence required some structural changes. In this case, the cost of removing and rebuilding the roof will add up to the final cost of the project.
Does It Add Value?
There is no doubt that loft conversion provides one of the best returns on investment. There is a rough estimate that adding an extension can add up to 20% value to your home. However, you need to make sure that the loft extension cost is not greater than the added value to your home. You have to do the math as you better know the property prices in your area.
The loft conversion can be completed under permitted development rights. However, you still need to obtain a certificate of lawfulness from local council which will cost you £86. If you also need planning permission then expect to pay £172 fees. In case of a semi-detached house extension, you will also need party wall agreement from the neighbours which typically cost between £600 and £1,000 per neighbour.
