Why Consider a Home Extension?
Every year, thousands of homeowners face a tough decision: move to a bigger home or extend their existing one? With UK house prices climbing and moving costs stacking up, extensions have become the go-to solution for adding space without the stress of relocating.
Unlocking the Potential of Your Property
Adding Space, Light, and Value to Your Home
An extension isn’t just about gaining extra square footage—it’s about transforming the way you live. Whether it’s an open-plan kitchen, an extra bedroom, or a dedicated office, extensions architects can design something that adds both function and beauty to your home.
Common Reasons Homeowners Choose to Extend
Growing family? Add a bedroom instead of moving.
Love your location? Stay put and expand instead.
Want more light? A rear extension with bi-fold doors can work wonders.
Need an office? A garden studio might be the perfect solution.
Alternatives to Extensions – Moving vs. Renovating
Moving is expensive—stamp duty, legal fees, agent costs, and removals quickly add up. Renovating is another option, but knocking down walls has its limits. A well-planned extension, designed by expert home extension architects, is often the best of both worlds.
Understanding the Costs and Benefits of Extending
How Extensions Can Increase Your Home’s Value
A well-designed extension can boost your property’s value by 10-20%. In high-demand areas, the return on investment is even higher.
Cost vs. ROI – Is It Worth It?
While a typical extension costs anywhere from £20,000 to £150,000+, it’s an investment that pays off in both lifestyle and resale value.
The Emotional and Functional Benefits of More Space
More than just bricks and mortar—an extension improves daily life. Extra space for family, entertaining, and working from home can transform your quality of life.
How Much Should an Architect Cost for an Extension?
While normal fees for architects range between 7-15% of the project cost, ours are lower at the following rates:
Single-storey rear extension: £950 including VAT. This includes the full planning application, liaising with the council until approval, and covering any amendments required by the council. Third-party fees (such as structural calculations) and the planning fee are separate, but we handle the structural calculations in-house.
Double-storey extension: £1,450 including VAT.
Loft conversion with a dormer: £950 including VAT.

Types of Home Extensions
Choosing the Right Extension for Your Home
Single-Storey Extensions
Great for kitchens and open-plan living, these are one of the most popular extension types.
Double-Storey Extensions
Adds both ground-floor and upstairs space, often more cost-effective per square metre.
Rear and Side Extensions
Maximises garden or unused side space to create more living area.
Wraparound Extensions
Perfect for transforming older homes with an open-plan, contemporary feel.
Loft Conversions and Dormers
Ideal if you need an extra bedroom or office but don’t want to lose garden space.
Basement Extensions – Are They Worth It?
A costly but incredible way to add space in urban areas where land is limited.
Conservatories & Orangeries – Aesthetic or Practical?
Adds light-filled spaces, but insulation and design matter if you want them to be usable year-round.
Factors That Influence Your Extension Type
Space Availability and Planning Permission
Your home’s layout and local council rules will dictate what’s possible.
Matching Your Home’s Architectural Style
Seamless designs add value—badly matched extensions can stick out like a sore thumb.
Budget Considerations for Each Type
Single-storey extensions start from £20k, while basement or double-storey builds can reach £100k+.
