Most of us have a sense that gardens are good for us. But between the vague wellness claims and the Instagram inspiration boards, there's a practical question that rarely gets answered: if a garden can support your wellbeing, what does that actually mean for how it's designed?
This is where the research meets the drawing board. The evidence we explored in our previous article on gardens and health points toward specific, actionable design principles — not mystical ideas, but concrete decisions a garden designer makes every day.
Here's how the science translates into the spaces we build.
Start with what you can see from inside
One of the most replicated findings in environmental psychology is that views of natural greenery reduce stress. Roger Ulrich's landmark 1984 study — 46 post-surgery patients at a Pennsylvania hospital — found that those with a view of trees required fewer strong painkillers and received significantly fewer negative nursing evaluations than those facing a brick wall (Ulrich, 1984, Science). His later work confirmed that nature views activate parasympathetic recovery within minutes (Ulrich et al., 1991, Journal of Environmental Psychology).
The design implication is straightforward: your garden should be composed from the inside out. The view from your kitchen window, your living room, your home office — these are the sightlines that matter most, because they're where you spend the most time. We design gardens so that key windows frame layered, green planting rather than bare fencing, bins, or empty hardscaping. Even when you can't step outside, a well-framed view is doing measurable work.
Design for gentle attention, not stimulation
Rachel and Stephen Kaplan's Attention Restoration Theory — developed over decades at the University of Michigan and supported by multiple meta-analyses — identifies four qualities that make an environment mentally restorative: a sense of being away from routine, gentle fascination, enough coherence to feel immersive, and a good fit with the person using it (Kaplan & Kaplan, 1989; Kaplan, 1995, Journal of Environmental Psychology).
In practical terms, this means gardens that hold your attention without demanding it. Moving water, rustling grasses, visiting birds, seasonal change — these are what the Kaplans called "soft fascination," and they allow your directed-attention system to rest.
It also means design that feels like a place, not a catalogue of features. A coherent layout with depth and layers is more restorative than a cluttered collection of individual elements. Curved paths that reveal the garden gradually create a sense of mystery and extent — two of the Kaplans' core restorative qualities — even in a modest suburban plot.
The practical test: if a garden can be seen entirely from the back door, it's missing the psychological "pull" that makes people want to step in and stay.
Create reasons to linger under trees
The forest bathing research — particularly Park et al.'s study of 280 participants across 24 Japanese forest sites — consistently shows that time spent beneath tree canopy is associated with measurably lower cortisol, reduced blood pressure, and lower pulse rates (Park et al., 2010). A 2019 meta-analysis of 22 studies confirmed the cortisol-reduction finding across multiple research groups (Antonelli et al., 2019, International Journal of Biometeorology).
You don't need a forest. You need canopy. A well-placed tree with seating beneath it — sheltered enough to feel enclosed, open enough to maintain a sense of prospect — applies the same principle in a Surrey back garden. Aromatic planting nearby (lavender, rosemary, pine) is consistent with phytoncide research, though the garden-specific dose hasn't been studied directly. What has been studied is the stress-reduction effect of immersive green space, and that translates to a design priority: create at least one spot where sitting still feels natural, not awkward.
Get the green-to-hard ratio right
Clare Cooper Marcus, who spent decades evaluating how people actually use therapeutic gardens in hospitals and care settings, recommended an explicit ratio: 70% green to 30% hardscape (Cooper Marcus & Sachs, 2013, Therapeutic Landscapes). Her research — drawing on extensive observational data across multiple therapeutic garden sites — consistently found that lush, layered planting with looping paths and semi-private seating niches outperformed sparse, hard-surfaced spaces.
This is one of the most directly actionable pieces of evidence in the literature. It doesn't mean every garden needs to hit exactly 70/30, but it does mean that the default should lean green. Paving serves access and function; planting creates the environment that supports how you feel. When we design, we think about how the hard surfaces serve movement and use, while the planting creates the atmosphere and the enclosure.
Make it easy to be outside in British weather
Perhaps the most practically important body of evidence concerns light and outdoor time. Kenneth Wright's camping studies at the University of Colorado found that just a weekend of natural light exposure shifted participants' circadian rhythms by 1.4 hours — achieving 69% of the effect of a full week (Stothard et al., 2017, Current Biology). Even a heavily overcast British sky delivers thousands of lux — at least several times brighter than a well-lit office.
Meanwhile, research consistently identifies weather as the primary barrier to outdoor time in the UK. And a major study of approximately 20,000 people in England found that spending at least 120 minutes per week in nature was associated with significantly better health and wellbeing (White et al., 2019, Scientific Reports).
This creates a clear design brief: remove the friction between indoors and outdoors. Covered seating areas — pergolas, louvred canopies, glass lean-tos — that allow you to sit outside in light rain without setup or commitment. All-weather surfaces that don't become treacherous when wet. Morning-facing seating for a coffee that doubles as circadian-relevant light exposure. South-facing sun traps with walls on two or three sides, creating sheltered microclimates that feel noticeably warmer than exposed areas on calm days.
Winter-interest planting matters here too. Structural evergreens, bark-interest trees like silver birch and paperbark maple, winter-flowering shrubs — these give you visual reasons to step outside between November and March, when the temptation to stay in is strongest.
The thread that runs through all of it
Every piece of research we've covered points in the same direction: a garden designed for wellbeing is one that's easy to be in, pleasant to look at from inside, and layered enough to hold your attention gently. None of this requires exotic features or specialist knowledge. It requires thoughtful design — understanding how light falls across a space, how planting creates enclosure and interest, how paths and seating encourage lingering rather than passing through.
These aren't wellness trends. They're design fundamentals, now backed by decades of replicated research. And they happen to be the same principles that make a garden beautiful, functional, and worth the investment.
We've been designing, building, and caring for gardens across Surrey for over 50 years — two generations of hands-on experience. The research confirms what that experience already taught us: the gardens people love most aren't the ones that look most impressive on completion day. They're the ones that keep drawing you outside.
