Home Extension Cost

HOW MUCH DOES A HOUSE EXTENSION COST?

Bespoke Construction Group has a wealth of experience creating a wide range of house extensions, making us the go-to construction company if you’re wondering how much a house extension costs. You may have heard that the cost of a house extension can vary widely depending on factors like size, materials, and complexity, but as a rough guide, house extension costs per m2 in the East of England typically range from £1,500 to £2,500 per square meter.

However, finding out exactly how much your home extension will cost is simple when you get in touch with our construction company. Instead of getting rough numbers, you can receive a detailed and personalised estimation from us. Whether you’re planning a single-storey extension or an elaborate double-storey extension, we can accurately tell you how much the project will cost.

What Determines the House Extension Cost Per m2 in the UK?

The cost per m2 of a new home extension could cost you anywhere from £1,500 to £3,500 per m2, and in some cases it could cost more. The cost can vary significantly due to several factors that will come into play when building your house extension.

Here’s a breakdown of the key elements:

Single-storey extension:

Generally the most affordable, costing around £1,500 to £2,000 per m².

Double-storey extension:

More complex due to increased structural work and materials, expect to pay around £1,800 to £3,000 per m².

Side extension:

These extensions can be tricky due to potential access issues and party wall agreements, costing roughly £1,700 to £2,500 per m²

Wrap-around extension:

Combines elements of rear and side extensions, making it one of the pricier options at £2,000 to £3,500 per m².

Size of the Extension: Smaller house extensions are often the most affordable, yet larger extensions can be more cost-effective as you’re getting more out of each m2.
Complexity: How complex an extension is to build and the addition of bespoke features will also affect costs.

Norfolk, Suffolk or Cambridgeshire: These areas are likely to come with a lower house extension cost per m2 compared to other areas.
London and the South East: Labour and material costs are typically higher in major cities.

Materials: Using standard materials in your build will be cheaper than using high-end finishes.
Labour Costs: Different contractors will come with their own labour costs, with more experienced and skilled builders costing slightly more.

Site Access: If materials and equipment are difficult to get to the site, it can lead to increased labour costs.
Ground Conditions: Issues like unstable soil or the need for excavation can add to the overall cost.

Professional Fees: You will typically require the assistance of architects, surveyors, and structural engineers for your house extension.
Necessary Applications: If your project needs extensive planning permission or building regulations, it can add to the cost.

CAN I EXTEND MY HOUSE WITHOUT PLANNING PERMISSION?

Yes, you can extend your house without planning permission under ‘Permitted Development Rights’, but this depends on the size and type of extension. For example, a single-story extension, such as a small 3 metre house extension, can usually be added without permission, as long as it stays within specific limits regarding height and distance from boundaries. We’re familiar with all the local regulations and can help you determine whether your project falls under Permitted Development or if planning permission is required. We handle all of the paperwork to ensure your extension is fully compliant, so you can focus on enjoying the process of turning your vision into reality.

WILL MY COUNCIL TAX INCREASE WHEN I EXTEND MY HOUSE?

Your council tax might increase after extending your home with a conservatory or extension, but it typically won’t happen until the property is sold or reassessed by the Valuation Office Agency (VOA). The size and value added by the extension can impact which council tax band your home falls into. However, our house extension builders can advise you on this during the planning stage and help you understand any potential implications. Our focus is on extending your home with a stunning home extension while ensuring your extension adds significant value to the property, making any future council tax increase a worthwhile investment.

HOW DO I EXTEND MY HOUSE CHEAPLY?

For an affordable house extension, it’s essential to plan smartly and make cost-effective choices. One option is to build a simple but high-quality single-storey extension with a straightforward design — this will help to keep costs down while also giving your home that little added space. You’d be surprised how just a small amount of added space can completely transform your property and improve day-to-day home life.

How much does a single-storey extension cost: Roughly £40,000-£140,000

How much does a double-storey extension cost: Roughly £65,000-£150,000

If you want to build a larger house extension, you can still ensure cost-effectiveness with our help. We can guide you through selecting affordable yet durable materials, maximising the space efficiently, and choosing a design that minimises construction complexity. By handling everything in-house, we also reduce project management fees and the risk of delays, helping you save money without compromising on quality. We focus on delivering value, so you get the most out of your budget.

CAN YOU EXTEND THE HOUSE WIRING?

Yes, you can extend the house wiring as part of your home extension project. A qualified electrician will be able to help regarding any electrical needs your project may have. At Bespoke Construction Group, we have several skilled tradesmen, including electricians, in our team of house extension contractors and will bring them into your project when we get to the stages they are needed, which is included in your overall home extension cost, so you don’t have to hire your own electrician and juggle invoices from multiple contractors. For peace of mind, we can guarantee that all work complies with the latest safety standards and regulations.

CAN YOU EXTEND THE HOUSE FOUNDATION?

Yes, it is possible to extend your property’s foundation, but there are a few things to consider, such as the type of extension you want to build, the soil conditions on your land, and any nearby obstructions like trees and drains. as part of our complete house extension service, we ensure that your home’s foundations can support the new structure and meet all safety standards. We do this by having our experienced team assess your current foundation and determine the best approach for the extension, whether that involves underpinning, adding new footings, or reinforcing existing structures.

TYPES OF HOUSE EXTENSIONS WE CONSTRUCT

Kitchen Extension

If you have a small kitchen in your home, you can make this important space larger with a kitchen extension.

By specifically focusing on expanding the size of your kitchen, you can create a spacious and functional part of the home that can be better enjoyed by you and your family. Plus, kitchen extension costs are usually more favourable than larger extension projects.

Kitchen-Diner Extension

A kitchen diner extension combines the kitchen and dining space, creating an open and sociable environment.

With a kitchen-diner home extension, you can create a large kitchen space that also features a luxurious dining area, giving your home a more open-plan layout and eliminating the feeling of being boxed in by a small kitchen with no proper dining space.

Single-storey Home Extension

A single-storey extension adds extra living space on one level, providing flexibility for various purposes.

A single-storey home extension is often used to add kitchen and kitchen-diner extensions to a home, but they can serve many purposes. This extension method is best for when you want just that small amount of extra space – you would be surprised by the difference a single-storey extension could make to your home.

Two-Storey Home Extension

A two-storey extension expands your home vertically, accommodating additional rooms or bedrooms on the upper floor.

Second-storey extensions provide more space than single-storey extensions while using up a similar amount of floor space, as you will be building outwards and then upwards for the second storey. Many of our clients have used this form of home extension to add another bedroom and bathroom to their home.

Timber Frame Extension

Timber frame extensions utilise wooden framing for a natural and aesthetically pleasing architectural choice.

As a sustainable building method, timber frame home extensions have risen in popularity and can work just as well as traditional brick extensions. This is a great choice if you want to build in an eco-friendly way, and this type of extension can be more affordable than conservatory extension costs, for example.

Bungalow Extension

Bungalow extensions enhance a single-story home, offering increased living space without altering the building’s height.

As houses that usually consist of only one floor, bungalow extensions are ideal if you wish to make your home more spacious. With this type of home extension, you could add an extra room to your bungalow, such as a bedroom or home office.

Side House Extension

Side extensions elongate the footprint of your home, often providing extra room for living or utility spaces.

A side home extension is built onto the side of a property, utilising any available space at the side of your home that may be going to waste. These extensions save you from using up space at the rear or front of the home.

Rear Home Extension

A rear extension extends the back of the house, serving as a versatile solution for expanding living areas or adding new rooms.

If you have some space in your back garden to spare, you could build a rear home extension. As these are located at the back of the property, they are commonly used for extending the kitchen space.
