Outdoor living is one of the clearest renovation trends for 2026. With more homeowners choosing to stay and improve rather than move, gardens are increasingly being treated as an extension of the house rather than an afterthought — sunrooms, screened porches, garden rooms and indoor-outdoor layouts are all seeing rising demand.
Here's what's driving the trend, what it actually costs in the UK, and what to check before you commit.
Why outdoor living is having a moment
Landscaping and outdoor living projects are consistently among the top renovation priorities homeowners report planning for the year ahead, alongside kitchens and bathrooms. Part of the appeal is cost-to-impact ratio — a garden room or improved outdoor space tends to be cheaper than an equivalent internal extension, while still adding genuinely usable square footage. Part of it is simply that homeowners want more from the space they already have.
Popular project types and typical UK costs
An insulated, powered structure separate from the house — used as a home office, gym or guest space. Most garden rooms under 2.5m in height and outside of certain boundary rules fall under permitted development, though this varies by property and council, so it's worth checking before committing to a design.
An attached, glazed extension of the house — more integrated than a separate garden room, but usually requiring more groundwork and building regulations sign-off, particularly if it will be heated year-round.
New patio, decking, planting and lighting. The lowest-cost entry point into outdoor living improvements, and often the highest return-per-pound project on this list because it improves how the whole garden is used, not just one corner of it.
Design ideas trending for 2026
- Indoor-outdoor flow: Bi-fold or sliding doors connecting kitchen or living space directly to a patio or garden room, rather than a single door
- Multi-use garden rooms: Spaces designed to flex between home office during the week and guest accommodation or entertaining space at weekends
- Low-maintenance planting: Drought-tolerant and native planting schemes that reduce upkeep without sacrificing look
- Outdoor kitchens and pizza ovens: A growing category as homeowners extend entertaining outdoors for more of the year
Before committing to any structure, check your permitted development rights against your specific property — rules differ for corner plots, listed buildings, and properties in conservation areas. A five-minute council planning portal check can save a costly redesign later.
Budgeting for an outdoor project
Outdoor projects are just as prone to scope creep as any interior renovation — a garden room quote can grow quickly once electrics, insulation upgrades and interior finishing are added. Treat it with the same discipline as any other renovation: agree scope in writing, add a 15–20% contingency, and track spend by category (structure, electrics, interior fit-out, landscaping) as the project progresses.
