How Much Does a Single Storey Extension Cost?
Thinking of adding more space to your home without moving out of the area you love? You’re not alone—many UK homeowners are now opting for single storey extensions to create more room, whether it’s a bigger kitchen, dining area, or home office.
But how much does a single storey extension cost in the UK? The answer isn’t simple—it varies based on several factors.
In this blog, we’ll break down the key elements that impact the cost of a single storey extension, helping you plan your project wisely.
How Much Does a Single-Storey Extension Cost in the UK?
When you start researching, you’ll notice that costs vary wildly. That’s because every home and every homeowner is different. Are you planning a sleek, modern glass-wrapped extension? Or a more traditional brick-built kitchen extension that flows naturally from your current space? These will have different requirements, both structurally and stylistically.
For those considering single storey extension cost, things can seem more straightforward, but even here, details matter. A smaller footprint doesn’t always mean a smaller budget. Factors like access, site preparation, and your chosen finishes can still add up, which is why it’s important to get professional guidance early on.
What Influences Your Single Storey Extension Cost?
A few key things shape how much you’ll need to invest:
1. Size and layout: A simple box-shaped room is generally easier (and cheaper) to build than a wraparound or L-shaped space.
2. Materials and finish: Are you going for budget-friendly finishes or high-end, architectural flourishes?
3. Location: A single storey house extension in a quiet countryside plot might be less complex than one in a compact South London terrace.
4. Planning requirements: Depending on where you live, you may need permissions and inspections that affect both the timescale and cost.
Finding The Right Builder Matters More Than You Think
The right partner won’t just handle the physical build—they’ll guide you through key decisions like layout, materials, and planning permissions, and help keep your project running smoothly from start to finish.
Look for someone with a proven track record in house extensions, particularly in your local area. It’s essential to find a builder who understands the style of the homes, is familiar with the local council’s planning processes, and knows how to work within the constraints of London properties.
A good builder like Doran Bros Construction will have a strong portfolio. You should check past projects, reviews, and ensure clear communication to avoid stress and achieve a smooth transformation.
