Why Choose A House Extension Over Moving?
Stay in Your Preferred Location
One major benefit of house extensions is avoiding the stress and expense of moving. You can keep your community, commute, and schools, while tailoring your Basingstoke home to your needs.
Cost-Effective Solutions
Moving home often involves unpredictable costs and a long chain. A well-designed extension can be more cost-effective, adding value and new living space for less than the price of upsizing. Our team helps you assess options that fit your budget – from updating a kitchen extension to adding an extra bedroom or building a double-storey extension.
Less Disruption, Faster Results
Compared to the months spent house-hunting, selling, and waiting for completion, extensions in Basingstoke can often be delivered in a matter of months. We help you plan each step and select extension builders known for clear timelines and minimising disruption to your daily life.
Popular Types of Extensions in Basingstoke
The right extension depends on your property, goals and budget. We specialise in a vast range of designs:
Perfect for kitchen extensions or creating a large open-plan living space at the rear or side of the house. Single-storey extensions typically cost less and can bring in natural light through bi-fold doors, roof lanterns, or Velux windows.
A double-storey extension adds vertical space, with bedrooms above and living or dining space below. They add significant value to your property and suit families who want more space without losing garden area.
Loft conversions in Basingstoke transform unused roof areas into functional rooms – think an extra bedroom, home office or studio. We guide you on which homes are suitable and how to create natural light and ventilation using Velux windows. Loft conversions are often more cost-effective than you’d expect and require fewer groundwork changes.
A garage conversion repurposes an attached or detached garage to create valuable new space, such as a playroom, study, or utility room. It’s a popular solution for families who need more room but have underused buildings on site.
A wrap-around extension combines side and rear ground-floor extensions, creating a spacious open-plan zone with great flow. These projects suit detached or semi-detached homes with available plot width and can dramatically increase both usability and value.
For Victorian or Edwardian terraces, a side-return extension can capture unused paths or side spaces, enlarging kitchens and bringing in more natural light. It’s a clever way to optimise a restricted footprint.
Extension Design and Planning: What to Expect
Each extension project in Basingstoke begins with an initial consultation to discuss your requirements, assess your existing property, and explain both opportunities and potential restrictions.
Our process covers a measured survey of your home to inform accurate design, 3D design and extension drawings to visualise each option and optimise space, submission of planning permission or permitted development applications where required, detailed building regulations drawings for builders and Building Control, and referral to trusted master builders and extension builders near you.
We’ll advise on the most suitable approach – whether permitted development rules apply or if you need full planning permission, especially in Conservation Areas or where you’re extending to the front of the house. We prepare everything for approval, including specialist reports such as flood risk assessments and bat surveys, and keep you updated with clear communication throughout.
Are You Aware Of Basingstoke Building Regulations?
Building regulations are separate from planning permission. They ensure every new space is structurally sound, energy efficient and safe. The builder in Basingstoke who completes your extension will work to these detailed plans, which are checked and signed off by local Building Control.
House Extension Costs & Budget Planning
The cost of an extension in Basingstoke depends on size, design complexity and choice of construction materials. We help you create a clear, realistic budget from the start, tailored to your project vision.
Typical Basingstoke extension builder costs are:
- Single storey extension: £40,000–£90,000
- Double storey extension: £80,000–£180,000
- Wrap around extension: £70,000–£150,000
- Loft conversions: from £30,000
Extension builders in Basingstoke often charge £16–£42 per hour, depending on the type of work and specialisms.
Factors affecting cost include ground conditions, property age, accessibility, chosen materials, such as eco-friendly options, and the inclusion of features like garden walls, large glass doors, or bespoke storage. We are fully transparent about costs and help you compare options, so you get the highest-quality result within your budget.
It’s worth noting that single-storey extensions are usually more cost-effective than double-storey designs and can maximise value without major upheaval. For larger household extension projects, the Community Infrastructure Levy may also apply to builds over 100m².

Frequently Asked Questions
The average cost for a single-storey extension varies from £40,000 to £90,000, while double-storey extensions can range from £80,000 to £180,000. Prices depend on location, materials, and the scale of building work.
Some house extensions, such as modest single-storey projects, may fall under permitted development rights and not require planning permission. Larger house extension projects, or those in Conservation Areas, generally require an application to the local council. Our service covers submission and guidance for both scenarios.
Double-storey extensions and wrap-around extensions usually add the most value by increasing living space across multiple floors. However, the right design for your situation, property type, and location will depend on your needs and budget.
A typical single-storey extension can take 3-5 months from design confirmation to completion, while more complex projects and double-storey builds may take 6-9 months, depending on the scope and any required planning consents.
We work with trusted, fully insured builders in Basingstoke who have extensive local experience and positive client feedback. We can recommend them for your extension project, or liaise directly with your chosen builder.
A 3×3 m single-storey extension typically starts at around £40,000–£50,000, depending on specification and ease of construction.
