To avoid putting a lot of weight on the house, constructors avoid using heavy slabs for the floor and instead use wood. 

When executing this project, you should be aware of the loft extension costs so you can prepare a logical budget. This article will help you learn how to save on loft extension costs and execute the project successfully!

How a Loft Extension is Done

A loft extension typically involves adding an extra space beneath the roof of your house. It is easy to make a variety of modifications on pitched roofs while it is almost impossible to charge a contemporary flat roofed house with a slab.

There are various modifications depending on the room and design you want for the extension, and all of them have different loft extension costs.

Dormer – This is very common for the UK homes and it is very affordable. It involves adding a vertical dormer on the roof and adding a window to it. Though it looks like a small modification, it needs a lot of financial planning.

Mansard – The loft extension costs for a mansard is slightly higher than that of the dormer. You will need larger vertical walls and more roof addition to bring the entire room higher. It comes with many variations like double mansard and L-shape mansard loft extensions.

Hipped loft extension – This can be complex, especially when doing a hipped to gable. It will attract large loft extension costs, and a proper budget consideration should be done. An expert will advise you on the best application.

A hipped loft extension may allow you to put large windows, a terrace, or a pergola if the costs allow.

How Loft Extensions are Charged

Loft extension costs are going through the roof due to the high cost of materials and hard economic times in general. Modern structural techniques can also be expensive, especially when you want the best designs.

Architect’s charges

Have you worked with an architect before? When calculating the loft extension costs, you should include the cost of hiring a professional architect such as Humphreysandsons from the UK.

They charge for drawing plans, making the permit application for you, and supervising the work. They typically charge 15% of the total cost of the project. However, there might be other charges, especially when they help with other services. They split the charges on their invoice for clarity unless you are comfortable with the package charge.

Constructor’s charges

This is the main contractor to work on your project. Most reliable constructors ask about 30% of the total cost of materials, but this may vary depending on the complexity of the loft extension project.

A constructor should not have other hidden charges because they are not likely to offer other services apart from what is covered in the scope, unless there are discussed and agreed changes.

Cost of materials

When buying materials, you should plan well through a professional. Materials vary in price, but you can save by going for modern materials that are affordable.

Most clients compare the prices of materials from different suppliers and see what will give them value for money. You too should do the same.

Permission application cost

Every government around the world charges for permit applications for construction projects. No matter how little the charges are, they need to be budgeted for. So, when planning the loft extension costs, do not forget to factor this in.

Fortunately, these costs are clearly indicated on authorities’ websites. What you might not know are the charges for a consultant who will help you with the applications. But you can always ask.

Miscellaneous costs

Every project has extra costs that are unprecedented. So, when budgeting for the loft extension costs, you should add some percentage for inflation, additional services and materials, and the like.

Some people add 10% of the total known cost of the project, which is a fair estimation.
