Most Irish streets were designed around one question: how do vehicles and people move through this space. Planting, where it appears at all, tends to arrive last, an optional extra if there's any budget left in the kitty, a few trees, containers or hanging baskets outside the shops in summer. Decorative, easily removed, with little or no thought for what plants can actually achieve in an urban landscape.
This means planting gets treated as the first thing to cut when a budget tightens, and the last thing to plan for when a street or a housing estate is being designed in the first place. It also means we consistently underestimate what planting, when done properly and built in rather than bolted on, can actually do for a place.
Cork's Patrick Street is a useful place to see that argument tested in real time, not in theory.
Patrick Street: A City Street Reimagined
For decades, the plazas outside Brown Thomas and the Savoy on Patrick Street were paving, footfall and bus stops. Functional space, not living space.
Cork City Council's greening pilot has installed large planting islands in constructed raised beds at both locations. Trees now anchor each planter, underplanted with a deliberately diverse mix of species rather than a single ornamental layer.
The trees, still young, are there to grow into shade canopy on a street that currently offers pedestrians almost none. The raised beds are designed to slow and absorb rainwater before it reaches the drainage network and, ultimately, the River Lee, a river with a well-documented flooding history in heavy rain. The diversity of species beneath the trees is designed to give pollinators, insects and small birds something a single-species scheme never could, food, shelter, nesting and hibernation sites, in the middle of a city centre.
The planting went in during the summer of 2026. There are no measured outcomes yet but what exists today is the intervention itself, real trees, real beds, real diversity, in one of Cork's busiest streets.
The Multiplier Effect Applied to Place
A greened street or square is usually approved, budgeted and judged against a single question: does it look better. In practice, one well-designed piece of green infrastructure on a street produces a set of independent returns at once, most of which never appear on the same balance sheet.
What one greened street might deliver
- Slows and reduces stormwater entering drains and rivers
- Cools the street and softens hard surfaces in summer heat
- Creates habitat and supports pollinators and urban biodiversity
- Removes pollutants and CO2 from the atmosphere, improving air quality
- Supports mental health through everyday engagement with and access to green space
- Increases the time people spend on the street, and how often they return, which in turn benefits local businesses
- Softens perception of a place, encouraging a sense of civic pride
- Strengthens social contact and neighbourly familiarity
- Contributes measurably to nearby commercial and property value
- Improves how a place looks and functions for visitors and investment
Ten outcomes. One greened street. If it slows flooding, cools a hot afternoon, cleans the air, supports biodiversity and lifts commercial value at the same time, why is it still budgeted and judged as if it only does one of those things?
What Does the Evidence Say?
Much of the research on trees, greening and commercial or social value comes from outside Ireland, particularly the United States. Irish-specific data on this exact question does not yet exist in the same depth. The findings below are real and peer-reviewed, but should be read as international evidence applied to an Irish argument, not as Irish outcomes already measured.
Trees and Retail Behaviour
Wolf, K., University of Washington
Multiple studies across US business districts
A series of consumer surveys across small, mid-sized and large US retail districts found that shoppers consistently rated tree-lined shopping areas more highly, reported willingness to travel further and stay longer in districts with mature tree cover, and were willing to pay 9 to 12% more for goods and services in shopping areas with large, established trees.
Street Trees and Home Sale Prices
Portland, Oregon
A study of street trees in Portland found that a single street tree added an average of $8,870 to a home's sale price. Applied across the city's housing stock, researchers estimated a cumulative property value increase of $1.35 billion, and roughly $15.3 million in additional annual property tax revenue.
Landscaping and Commercial Rental Rates
Journal of Arboriculture
Commercial properties with quality landscaping commanded rental rates around 7% higher than comparable properties without it, a direct commercial return from the same planting that also delivers shade, stormwater absorption and visual quality.
Urban Green Space and Social Cohesion
Published in a peer-reviewed environmental science journal, 2021
A systematic review of research on public green spaces found consistent links between the presence and quality of green space and stronger social cohesion, including greater sense of community, more frequent neighbour interaction, and increased cross-group social contact in areas with well-used, well-maintained green space.
Planting on a street doesn't know it is an economic asset. It just gives people a reason to slow down, sit, and stay a little longer. Multiply that by every street in a town, and the effect on how a place is valued and remembered stops being small.

The Bigger Opportunity: Designing Nature Into New Communities
Everything above describes retrofitting, adding planting to a street that was built without it, years or decades after the fact. Patrick Street proves it can be done, and that it's worth doing. But it also proves something less comfortable: that we are, again, adding this in after the fact, on a street that has existed since long before any of us were born.
Most new housing in Ireland is still built the same way that street once was. A development gets its roads, its footpaths, its parking, its boundary treatments, and only then, if anything is left in the landscaping budget, does planting get considered, usually as a strip of lawn and a fast-growing hedge along the boundary. Functional. Cheap. Rarely designed to do anything beyond exist.
Imagine, instead, a new housing estate designed the way Patrick Street is now being retrofitted, tree canopy planned in from the first drawings, raised beds and permeable planting built into the drainage strategy rather than added around it afterwards, a genuine diversity of species designed into shared green space from day one rather than a monoculture hedge chosen for how fast it grows and how little it costs. Every one of the returns described above, cooling, biodiversity, stormwater management, social cohesion, property value, would be present from the day residents move in, not decades later if a council ever finds the budget to retrofit it.
This is not a call for more planning regulation. It's a much simpler observation: we already know what well-designed planting delivers. The only real question is whether we keep treating it as something to add later, or start treating it as part of what a new home is, from the outset.
Why This Matters Now
Housing delivery is, right now, one of the most urgent and closely watched conversations in Ireland. In 2025, Ireland recorded 36,284 new dwelling completions, the highest annual total since CSO records began in 2011, and a 20.4% increase on 2024. Of those, 18,308 were scheme dwellings, homes built as part of multi-unit developments of two or more houses, over half of all completions for the year.
That scale matters here specifically. Scheme dwellings are exactly the category where planting decisions get made once, centrally, at design stage, and then repeated across an entire estate. It is the single biggest lever available for building the returns described above into new Irish housing at scale, rather than site by site, years after the fact.
Even in a record year, completions remain well short of the government's own target of roughly 50,500 homes annually through 2030. Ireland is going to keep building housing at real scale for years to come. Every one of those developments is a choice point: repeat the token lawn and boundary hedge, or design in the kind of planting Patrick Street is only now retrofitting onto a street that has existed for generations.
This is horticulture hiding in plain sight inside a conversation that, on the surface, has nothing to do with gardens at all.
This Is Already Happening
As with the other pages in this series, the case for planting as placemaking is not only a research question. It is already visible in programmes working on it in Ireland today.

Get In Touch →Town Centre First
Launched by the Department of Rural and Community Development and the Department of Housing, Local Government and Heritage in 2022, Town Centre First is a national policy putting placemaking and regeneration at the centre of how Irish towns are renewed. Every local authority now has a dedicated Town Regeneration Officer, and dozens of towns have completed Town Centre First plans developed with their own local Town Teams. Increasing housing supply within town centres is explicitly named among the policy's opportunities, precisely the intersection this page is arguing for: regeneration, placemaking and new housing treated as one connected question rather than three separate ones.
Cork City Council's Greening Pilot
Patrick Street itself is the clearest local example: a live, council-led pilot testing exactly the kind of intervention this page describes, in one of Cork's busiest public spaces.
Four Ways Horticulture Supports Placemaking
Making Streets Work Harder
Trees and planting on existing streets deliver shade, stormwater absorption, biodiversity and commercial uplift from the same intervention, as Patrick Street is now testing in real time.
Building Value, Not Just Beauty
Research consistently links tree cover and quality landscaping to measurable increases in property value, commercial rents and retail spend, alongside the environmental and wellbeing benefits.
Strengthening Civic Life
Well-designed green space is associated with stronger social cohesion, more neighbourly contact and greater civic pride, returns that rarely appear on a parks budget line but shape how a place is lived in.
Designing It In, Not Bolting It On
The clearest opportunity is not retrofitting older streets, valuable as that is, but designing planting into new housing developments from day one, at the exact moment Ireland is building homes at record scale.
One reason placemaking fits naturally within the wider argument of this series is that the same tree cooling a street and slowing its rainfall is very rarely doing only that. It is also raising the value of the property behind it, giving neighbours a reason to stop and talk, and giving a place something worth remembering. Placemaking is rarely funded, planned or measured alongside those other outcomes, even though the same intervention produces all of them at once.
Looking Ahead
Patrick Street shows what's possible when planting is added back into a street that was built without it. The more significant opportunity is not undoing that mistake street by street for the next fifty years, it's not repeating it in the tens of thousands of new homes Ireland is building right now.
- Real, measurable returns from street-level greening: cooling, stormwater management, biodiversity, commercial and property value, social cohesion
- Patrick Street as a live, Irish, unfolding example, with outcomes still to be measured over time
- A genuine, current opportunity to design these same returns into new housing from the outset, at the scale Ireland is currently building
- A national housing conversation that horticulture has, so far, barely been part of
Placemaking is only one part of the Beyond Gardens story. The same planting decisions shape climate resilience, biodiversity, and the physical and mental health of the people who live alongside them, often from a single intervention and a single budget line. The wider challenge is not simply understanding what horticulture is. It is understanding what horticulture can help us achieve.
