In recent years, garden buildings have surged in popularity across the UK — from sleek home offices to stylish garden bars and even private steam rooms. But beyond their aesthetic appeal and practical uses, many homeowners are wondering: do garden buildings actually increase house prices?
With more people working from home and using outdoor spaces creatively, a well-designed garden building can significantly enhance your lifestyle. But can it also boost your home’s market value?
Let’s explore how much value garden buildings can add, which types are most effective, what planning rules apply, and how to ensure you get the best return on your investment.
Can a garden building add value to your property?
Yes — when done properly, a garden building can boost your property’s value by up to 5–15%, depending on its use, quality, and how well it complements the rest of your home.
Buyers are increasingly seeking extra space — especially for home working, hobbies, or wellness. A garden building offers additional usable square footage without the cost and disruption of a full extension. In a competitive property market, it can make your home stand out and sell faster.
However, not all garden buildings are equal. Let’s take a look at which types tend to add the most value.
What type of garden buildings add the most value?
The type of structure you build – and how you use it – plays a major role in its impact on house value. Here are some of the most value-boosting options:
Garden office
With remote and hybrid working now the norm, garden offices are in high demand. A dedicated workspace away from the main house adds major appeal — particularly for professionals seeking peace, privacy, and a better work/life balance.
Value-added: High — especially in urban areas.
Top tip: Ensure it’s insulated, has power, and strong Wi-Fi access.
Garden gym
A fully equipped garden gym can be a big win for health-conscious buyers. It saves time and money on travel, and makes fitness more accessible — a growing priority post-pandemic.
Value-added: Moderate to high if well-designed.
Top tip: Install ventilation and non-slip flooring.
Garden studio
Garden studio, one of the most versatile options can be used for art, music, yoga, or other hobbies. It’s especially appealing to creatives, therapists, or parents wanting a playroom or quiet retreat.
Value-added: Moderate to high depending on use.
Top tip: Design with flexible use in mind for resale appeal.
Garden bar
While more lifestyle-oriented, garden bars are a trendy addition that can enhance your home’s entertainment value. While it may not significantly increase value alone, it adds wow-factor and can sway a potential buyer emotionally.
Value-added: Low to moderate.
Top tip: Keep the design tasteful and adaptable for future use.
Garden steam room
Garden steam room falls under luxury garden buildings and may appeal to a niche market. It could impress in higher-end homes or wellness-focused buyers, but isn’t likely to deliver a broad ROI unless integrated well into a larger spa setup.
Value-added: Low unless part of a full spa suite.
Top tip: Ensure waterproofing and ventilation meet building standards.
Garden pods
These compact, modern structures are stylish and multi-functional — garden pods are great for offices, guest rooms, studios, or even Airbnb use (subject to planning). The more self-contained they are (i.e. with electrics, plumbing, insulation), the more value they can offer.
Value-added: High if well-specified and usable year-round.
Top tip: Go for high-quality materials and eco-friendly design.
Factors that influence how much value a garden building adds
Even the most stylish garden room won’t add value if it’s poorly built or impractical. Here are key things buyers and surveyors look for:
- Quality of construction: Is it built to last with good insulation and materials?
- Usage: Is the space functional and desirable (e.g. office, gym, guest room)?
- Design: Does it complement your garden and not take up too much of it?
- Access: Is it easy to reach and well connected to the main house?
- Flexibility: Can future buyers repurpose it easily?
The best value-adding buildings are those that feel like a natural extension of your home — not just a shed with windows.
Planning permission and UK regulations
Many garden buildings do not require planning permission, thanks to Permitted Development Rights — but there are rules to follow.
When you don’t need planning:
- The building is single storey
- Under 2.5m in height (if within 2m of a boundary)
- Takes up less than 50% of your garden
- Not used as living accommodation
- Not built on listed properties or in conservation areas
When you do need permission:
- You plan to use it as a separate living space (e.g. Airbnb or annex)
- It exceeds the size or height limits
- It includes plumbing for kitchens or bathrooms
- Your property is listed or in a restricted area
Even if planning isn’t required, building regulations may still apply — especially if the structure includes electrics, plumbing, or will be regularly used.
Note: Always check with your local planning office to be safe. Read more here.
What do estate agents and surveyors say?
Most estate agents agree that a good-quality garden building can help a home sell faster — particularly offices and multi-use pods. Surveyors will assess how permanent the structure is, its condition, and whether it complies with local planning and regulations.
Some lenders also factor in usable space when valuing a home, so if your garden building is heated, powered, and properly documented, it could positively influence the final figure.
Worth the investment?
If you’re planning to stay in your home for a while, a garden building can greatly improve your quality of life — and potentially increase the value of your property if done properly.
Garden offices, studios, and high-quality pods are the top value-adding options. Meanwhile, bars and steam rooms may boost lifestyle appeal but won’t always increase the price tag.
As with any home improvement, it’s about striking the right balance between functionality, quality, and cost.
