Design with a diplomatic core

To be honest, some kinds of garden design leave me cold, but I have to admit to being impressed by Peter Stam's elegant work at the Dutch embassy on Dublin's Merrion Road. Somehow, while having to be mindful of factors such as security, car-parking, vast over-hanging conifers and indelible pre-existing features - including an enormous cruciform pergola - he has managed to produce a garden that has the right ambassadorial flavour. And in a true spirit of diplomacy, there is something to please everyone.

There are froths of flowers for the sentimentalists, stern lines for the masterful types, neat logical associations for the bureaucrats, sitting areas for the socialites and enough rare and interesting plants to keep the most discerning plantsperson busy.

But please, don't go causing a traffic jam outside the embassy trying to get a look. Winter still has the brand-new garden in its grip, and anyway, all that is visible from the road is a cool formal space which musters as much dignity as is possible while having to provide launch pads for several diplomatic cars.

The real interest is around the back, where the sizeable garden is hemmed in by immense trees: with tall poplars and griselinia on

one side, and Monterey cypress (Cupressus macrocarpa) - a sort of big-house equivalent of the Leyland's cypress that surrounds properties all over Ireland - towering over the back wall.

Recent refurbishments at the embassy have added an airy atrium at the rear of the 1920s building. The new open-plan extension can be pressed into service as an entertainment space, and it opens out in to a large patio straddled by a leviathan concrete-andtimber pergola.

Every design project has its challenges, and Peter Stam gets full marks for the way in which he graciously embraced the latter grey-pillared mammoth - he had no part in its conception or form - and made his landscape flow around it. Instead of trying to distract attention from the obstinate structure (about which he is far too polite to say a negative word) he has obligingly based the design of the garden on it, echoing its lines and the curve of the underlying patio again and again in his plan.

(Which prompts me to offer a little timely advice to those thinking about major house-and-garden reconstructions: why not appoint a garden designer at the same time as the architect so that the two can work hand-in-hand, rather than one having to adopt and adapt to the other's ideas?)

Peter's design continues the bold thrust of the pergola in the form of a straight gravel path which shoots to the end of the garden. There a curved hornbeam hedge and an arc of Kilkenny marble seating repeat the contours of the patio. The path is lined with slim, upright yews (Taxus baccata `Fastigiata Robusta') which carry on the parade of the pergola's concrete pillars - their cold grey nudity soon to be decently and greenly clad in a covering of small-leaved ivy (Hedera helix `Baltica').

Concentric near-circles of soil beds and grass flow out from the patio like ripples from a pebble thrown into the water. And around the perimeter walls, Peter has created a kind of miniature woodland which makes a nicely proportioned under-storey beneath the mature poplars and cypresses that look down from the neighbouring property. Semi-mature trees, up to six metres in height - including maple, southern beech and the golden rain tree (Koelreuteria paniculata) - were imported to give instant presence. And along the north-facing wall, under the poplars, there is a minijungle of tree ferns and bamboos.

These were supplied by Peter from his nursery in Waterford, where he specialises in exotics, including about 80 varieties of bamboo. Peter, who is originally from Rotterdam and who worked there as a garden designer (after forsaking a "promising career" in the bank), moved to Ireland about 10 years ago. While building up his design business here, he started the nursery, rescuing bamboos from old gardens around the country.

There are more bamboos and ornamental grasses in the beds near the house, including the yellow Phyllostachys bambusoides `Castil loni', one of the first bamboos to be introduced into Europe from China. The grasses, bamboos and taller perennials, such as the lovely Joe-Pye weed (Eupatorium maculatum `Atropurpureum'), rise above swathes of shorter herbaceous perennials and lead your eye into the outlying "woodland".

Or so I've been convinced by the persuasive Peter Stam and his sets of blueprints, for although the new garden has been planted for a month or two, it is still wearing its stripped-down winter livery. Which makes me appreciate that the job of the garden designer or landscape architect is not an easy one: what you see on paper bears no resemblance to what you will see when the garden reaches maturity, usually in about three years. As Peter says, "You are really selling the customer an illusion". And in this case, I think it is a very fine one.
