If one UK sporting venue rivals Wembley stadium in global recognition, it is Aintree racecourse in the northern suburbs of Liverpool. For just three days every April, the Grand National attracts an amazing 600 million viewers across the world, more than any other horserace in history.

As a result, Aintree鈥檚 buildings are on show nearly as much as the horses themselves. Until very recently, though, the potential of the architecture to promote the event was lost on the racecourse owners. The four existing grandstands were about as inspiring as a 1970s business park.

But no longer. At last, the excitement of a top horse race is properly expressed in Aintree鈥檚 two latest grandstands, which are being finished in time for this year鈥檚 big race on 12 April. As designed by 好色先生TV Design Partnership (BDP), the identical twin buildings come in bold, bulging, sculptural forms. 鈥淲e鈥檝e avoided the usual structural expression of sports stadiums and gone for something more theatrical instead,鈥� says project architect Andrew Capewell.

Departing from the norm may prove a wise move. The last major racecourse grandstand to be completed, Ascot in Berkshire, hit the headlines after race-goers complained of obstructed views, and 拢10m of remedial work had to be undertaken (see box, page 44). The contractor on that project, Laing O鈥橰ourke, was also responsible for building the Aintree grandstands.

But, as Capewell says, Aintree is a very different animal. At the back of each grandstand, shiny zinc cladding curves round the eaves and sweeps down a steeply sloping rear wall. On either side rise two drum-shaped stair and toilet towers clad in rustic rough-sawn larch boarding. The sharp contrast between the zinc and the timber will eventually be softened by creepers growing up through trellis attached to the rear walls.

The architectural flamboyance intensifies in the central link block 鈥� a bow-fronted glazed bridge that crosses the wide, open-air gateway to the racetrack. The bridge is capped by the four circular peaks of a white tensile-fabric structure.

The trackside of the two grandstands is more subdued. It consists of three tiers of open-air terracing for standing at ground level and, interspersed by three balconies, sitting up above. Clear glazing is used around the tiers and balconies: for balustrading at the front to maintain a clear view of the racetrack, and for window walls behind the balconies enclosing hospitality suites. Overhead, shelter is provided by large steel canopies that cantilever forward and curve gently like the peaks of two baseball caps.

It is the gateway formed by the two grandstands that is the USP of BDP鈥檚 scheme. It serves as a processional arch through which the horses are led to the starting line. At the end of each race, the procession goes into reverse when the six winning horses are led back through the arch to their paddock. In this way, the arch turns two key acts of the racing ritual into colourful spectacles with the horses, fittingly, in the lead roles.

The horses鈥� processional route is also the centrepiece of a wider 拢35m masterplan for the racecourse drawn up by BDP. The problem was that horses being led to and from the races crossed paths with the spectators streaming towards their grandstands. In an earlier phase of the upgrading completed last March, BDP built a minor complex devoted to the horses. It consisted of saddling boxes, jockey鈥檚 changing rooms, a glass-fronted weighing room and a paddock, or parade ring, with a media centre thrown in below the weighing room. As the two-storey building is curved and terraced where it overlooks the parade ring, these combine to form a compact amphitheatre for viewing the horses. Then, before the race, the horses and jockeys are led for another 100m between two steel fences and through the arch to the starting line.

The internal layout of the two new grandstands is largely dictated by their particular relationship to the racetrack. They have been allocated no-brainer sites plonked on to the end of a row of three existing grandstands, and this has left them overlooking a sharp corner in the racetrack. However, this turned out to be a fortunate location, partly because it set the two new stands slightly back from the track and partly because the track stretches out at sharp angles in both directions, rather than passing straight across from side to side.

This saved them from being blighted by the low viewing angles that have afflicted the much wider grandstand at Ascot. As a result, the tiers have been given relatively gentle rakes and even accommodate circulation aisles that lead sideways to the lift and stair towers flanking each grandstand. Tony McGuirk, BDP chairman, describes each grandstand as forming 鈥渁 giant perch鈥� for viewing the races.

At the same time, shifting vertical circulation to the sides freed up the rear portions of the grandstands so they could be entirely devoted to bars, hospitality suites and their kitchens. Given that Aintree stages races for a mere seven days a year, conferences, exhibitions and other receptions are vital to the commercial viability of the racecourse. When the open terraces and enclosed rooms are used simultaneously, the two grandstands together accommodate a total of 6,700 spectators.

Hospitality suites range in size from 20-seater private boxes on the top storey to a capacious 600-seater dining hall on the first floor. The two larger hospitality halls are enlivened by dramatic wave-like ceilings of wide plaster strips that rise sharply from the rear walls before curving up and over to drop down to the window wall facing the track.

The two saddle bars that occupy the bridge link between the grandstands resemble crush bars in a theatre. Both are triangular in plan and have curving window walls overlooking the horse鈥檚 parade ring at the back and their processional route passing directly below, while the upper bar beneath its fabric roof evokes an marquee in a country fair.

Other than the distinctive ceilings in the larger halls, the interiors of the two grandstands consist largely of narrow corridors with right-angled corners and standard-issue doors and fittings in American oak. The ambience is one of bland, corporate hospitality, as in a commercial conference centre, which is at variance with the theatrical forms and arresting materials of the exterior.

No doubt this note of blandness is a legacy of the fixed-price design-and-build contract awarded to Laing O鈥橰ourke. More encouraging is the fact that the theatrical exterior of the two stands have both escaped such drastic value engineering. This shouldn鈥檛 be lost on those 600 million viewers across the world.
