Garden Rooms: The UK’s Biggest Home Upgrade Trend in 2025

With house prices still sky-high and the UK housing market harder than ever to navigate, more homeowners are ditching the idea of moving and choosing to upgrade their homes from the garden up.

Enter 2025’s hottest home trend, garden rooms: “A garden room isn’t just an extension—it’s a lifestyle upgrade,” says Roy Wetherall, MD, at Green Retreats. “You get the space you need, boost your home’s value, and skip the stress of moving.”

Research shows that over the past year, interest in garden room installations has jumped by over 31% as homeowners look for smart, cost-effective ways to add space without uprooting their lives. With the European market forecast to grow at a compound annual growth rate (CAGR) of 8.5% through 2033, this is no passing fad—it’s a shift in how people think about home.

4 Reasons Homeowners Are Saying Yes to Garden Rooms

1. The housing market? Still a rollercoaster.

Selling now could mean accepting a lower-than-expected price or waiting months for the right buyer to come along. And even then, there’s no guarantee—chains collapse, financing falls through, and prices dip overnight.

That’s why more homeowners are hitting pause on the “For Sale” sign and choosing to invest in their existing space instead. A well-designed, insulated garden room can add significant value to your home—not just in lifestyle, but in resale potential too.

2. Moving house can cost £30,000 or more.

For the same cost—or often less—you could have a stunning, fully insulated garden room installed right in your garden. Whatever your space needs, a garden room delivers lasting value and immediate lifestyle improvement.

“It felt like a no-brainer,” says Tom R., a homeowner from Bristol. “We were looking at nearly £25,000 in moving costs. Instead, we built a garden room—and now we have an office and chill-out space that’s added value to our home and our lives.”

3. It takes months to move. A garden room takes days.

Selling your home, finding a new one, dealing with surveys, chains, legal delays—it’s a process that can easily stretch to 4–6 months or longer, often with setbacks along the way. It’s not just time-consuming—it’s exhausting.

In contrast, a garden room can often be designed, approved, and installed in as little as 2–5 days, depending on size and complexity. No estate agents. No broken chains. No boxes piled high for weeks.

4. We love our home. We just needed more of it.

For many, it’s not the house that’s the problem—it’s the space. Bedrooms feel cramped, the kitchen’s chaotic, and remote work means the dining table has become a permanent desk. But despite the squeeze, the thought of moving is heartbreaking.

A Smarter Way to Create More Space

From remote work setups to home gyms, garden rooms are proving to be one of the most versatile and high-impact home improvements available to UK homeowners today.

“We considered moving, but the costs were just too high,” says Sophie B. from Oxford. “We added a garden room instead—and it’s completely changed how we live. I finally have a proper office, and the kids use it as a quiet reading room after school. It’s the best decision we’ve made for our home.”

Garden room benefits include: 

• Flexible – Custom-built for how you live. Whether it’s work, wellness, or play, garden rooms can be tailored to suit your lifestyle and evolve with your needs.
• Fast – Unlike home extensions or full-scale renovations, many garden rooms can be installed in just a few days, with zero disruption to your main home.
• Futureproof – Garden rooms don’t just add space—they add value. They enhance daily life now while strengthening your home’s market appeal later.

“A garden room is more than a quick fix—it’s a strategic investment that supports how we live and work now,” says Roy Wetherall, “In an uncertain market, it’s a smart way to upgrade your home—without uprooting your life.”

As the way we live continues to shift, garden rooms are becoming the go-to solution for homeowners who want more from the home they already love.
