So, you’ve got your foot on the property ladder, but how do you make the most of your new asset? An extension could add value to your home and give you extra living space.

Read on to find out what some of your options could be.

Single-storey extensions

Many older properties have small kitchens which don’t have space for all the latest juicers, bread makers, blenders and other modern zparaphernalia. A single storey extension at the back of a property is a relatively easy and low-cost solution, and you could have an impressive kitchen diner at the end of it.

As a guide, you can expect to pay anything from £1,200 to £2,000 per square metre. You should also factor in an extra 10-15% to cover fees for planning, building regulations, an architect and so on.

Two-storey extensions

If you have space at the side or back of your property, or a garage that isn’t in use, you could potentially build a two-storey extension. This will not only add more space to the downstairs living area, it could also create extra bedrooms and a bathroom.

As a rule, the cost of a two-storey extension is around 50% more than a single-storey, so it’s often more cost effective to go all out with a two-storey extension. When done properly this type of extension can significantly increase the value of your home.

Loft conversions

Loft conversions come in all shapes and sizes – from simply boarding over the floor and adding a window in the roof, to complex work such as creating a new roof and installing a bathroom.

Prices can start from as low as £15,000 and reach upwards of £55,000, depending on the complexity of the work and the finish.

However, be warned there are numerous properties that can’t have a loft conversion due to size issues. So, before ploughing ahead and drawing up designs of what your dream loft will look like, make sure to get it checked out first.


The addition of a conservatory is a great way to add space and natural light to your property. Prices vary massively as there are many different options you could go for.

When planning your conservatory, think carefully about what you want the new space to be used for - a spacious dining area, a place to sit and enjoy the garden, or a play area for the kids?

Before you get started

Prior to beginning your extension, it’s important to have all the necessary permissions in place.

First of all, apply to your local council for planning permission. Then, if your extension requires building against a wall that you share with your neighbour (a party wall), you’ll need to carry out a party wall survey - important as it ensures that you have evidence of the condition of the party wall, on both sides, before and after the works are carried out.

Whether it’s worthwhile investing in an extension depends on the how much the value of your home increases as a result of having the work done. If the work costs more than the value gained, you may be better off leaving things as they are and putting your money elsewhere.
