House Extension Ideas for Every Budget

There will come a time when you’ll need extra space in your home, whether it’s because your family is growing, or perhaps you want to create a home office to focus on your business.

Sometimes, moving isn’t an option due to the high removal costs involved in a big house move. Space can be easily created with a house extension, giving the extra room you require for you or your family.

Luckily, a house extension doesn’t always have to be pricey. There are some extensions that are easily doable which still give you enough space to expand. 

Let’s explore the different types of house extension that will suit every budget.


Open Plan Living

By knocking down an interior wall and creating an open-plan layout in your house, you can easily create extra space that you didn’t even know you had. Awkward walls and doorways can sometimes take up valuable space, with the best solution being to knock them down.

The most popular open plan living structures are a living room area that continues to a dining room and kitchen space, creating a light and open space to live in

To demolish an internal wall, prices will vary. To knock down one-brick-thick wall it can cost  £40/m², to knock down a 100mm block wall it will roughly cost £20/m² and a timber stud partition wall can cost £41/m² to demolish.


Garage Conversion

A garage conversion is a cheap way to add extra space to your house without having to carry out extension work. If you already have a garage, it’ll be quick and easy to convert it into a living space. Whether it’s an extra bedroom, laundry room or a home office, a garage conversion offers endless opportunities for an additional room.

A garage that is attached to your home typically falls under permitted development, meaning you won’t need planning permission. Most garages end up as a storage unit for items we rarely use, so a well-executed garage conversion can also add great value to your home if you do plan on selling it soon.

The typical price for an integrated garage conversion is roughly £8,000 (or £400-640/m²). You can definitely do this for less if the garage already has decent flooring, plastering and utilities etc.


Loft Conversion

Again, a loft conversion can be another way to create more space in your house, without having to spend much money. If the space is already there, a loft or attic conversion will give your home the addition of a functional space. This is ideal if you need an extra bedroom for your expanding family or a guest room for visiting family and friends.

A loft conversion typically doesn’t require planning permission, as the space already exists. Unless you want to build on to the loft, you won’t have to worry about applying for planning permission, avoiding extra building costs.

A basic room in a loft conversion will cost around £15,000.


Single-Storey Side/Rear Extension

If you’re looking for that extra bit of space in your home, a single-storey side or rear extension is a great option as it allows for a fresh start. Typically, single-storey extensions are usually turned into kitchens or an extra living room area.

The extension cost will depend on the type of room and the facilities that are needed for the extension. Although more expensive than just a conversion of existing space, a single-storey extension that blends in with the rest of your home can add a significant amount of value to your home, as well as providing you with that much-needed space.

For a single-storey extension of 4m x 5m, it will roughly cost around £30,000. This can be done significantly cheaper, depending on the utilities and features needed in the room.


Upsize to a New Home

Sometimes an extension just won’t be the solution, especially if you need a significant amount of extra space. Moving to a new, bigger house is a great way to gain that valuable space, whilst also creating a fresh start for you and your family.

To move house on a budget, make sure you’ve decluttered some of your belongings beforehand, this not only allows you to donate or recycle items you rarely use, but it will also reduce the removal costs of your house move as you are taking fewer items.

Have you considered a house extension or renovation? I’d love to know what you have planned. 

All costs are taken from Homebuilding & Renovating and will vary depending on your requirements.
