Here’s everything you need to know about adding another storey to your home.

What is an upstairs extension?

An upstairs extension is exactly what it sounds like – a new floor built on top of your existing home or garage. You can extend upwards in any shape or size that suits your needs, but if you want to create more than one room then we recommend looking into creating a loft conversion instead.

What are the benefits of having an upstairs extension built?

There are plenty of reasons why homeowners decide to add another storey onto their property, including:

Adding more living space – Whether it’s for your growing family or just so you have somewhere else to retreat from everyone else, adding extra rooms can make life easier in many ways.

The cost of building an extension varies depending on the size, complexity and location of the job.

How much does it cost to build a second floor extension?

The cost of building an extension depends on several factors:

The size of the project – The larger the extension, the more expensive it will be. A simple addition such as extending only one room will cost less than adding a conservatory or garage. On average, extending just one room costs around £20 per square metre (m2). A conservatory typically costs about £25 per m2 while adding an additional storey onto your property could cost up to £35 per m2.

Where you live – The price of building work depends on where you live in the UK so rates vary across England, Wales and Scotland. In London for example where there is high demand for builders there are fewer tradesmen available

How much does it cost to build a second floor extension?

Costs and prices for building a second floor extension will vary depending on the size, complexity and design of your project, but here are some average figures to help you get started:

The national average cost of a two storey extension is around £38,000. This price includes the excavation work required, foundations, walls and all internal finishing work such as plastering, flooring and electrics. Windows are not included in this price. The total cost can vary depending on factors such as location and the size of your property.

The national average cost of an attic conversion is £45,000 to £50,000 including windows but excluding the kitchen and bathroom fittings. To convert an attic into habitable space you will need to install insulation throughout the roof space before converting it into living accommodation using dry lining or insulation boards as well as installing new stairs leading up to the newly converted room.

The cost of building a second story extension is going to vary depending on a number of factors. The size and type of home will be the first thing that you need to consider, as well as the location in which it is being built.

For example, if you are building an extension in London then you will have to take into account the cost of labour and materials, whereas if you were building one in the countryside then the costs would be much lower.

The type of work that needs to be done will also affect the price. For example, if you are simply adding on a room then the costs will be much lower than if you are creating an entire new floor with walls and windows etc.
