London Design Festival 2016: organisers of the London Design Festival are discussing the fate of its flagship crazy golf project for Trafalgar Square after a Kickstarter fundraising campaign looked set to fail to meet its target.

Featuring holes by the likes of furniture designer Tom Dixon, fashion designer Paul Smith and the late architect Zaha Hadid, the Visionary Crazy Golf project needs to raise £120,000 before its deadline at midnight tonight, but has so far only raised £22,616 - less than a fifth of the target.

The project, described by the festival as the "most ambitious" of its annual interventions in the iconic central London square, could now be abandoned.

In an email sent 10 days before the deadline date on 27 May, the organisers made a last-ditch attempt at enticing backers, and said the project would not proceed unless it hit its funding target.

"If we fail to meet the Kickstarter target, unfortunately this project won’t be able to go ahead, so your support is crucial," the email read.

Had it been reached, the £120,000 Kickstarter target would have been matched by sponsors to allow the nine-hole course to be constructed.

An LDF representative told Dezeen today that the organisation were deciding what to do next.

Other designers who have created holes for the course include artist Mark Wallinger, printmaker Camille Walala and architecture studios Atelier Bow-Wow, HAT with Tim Hunkin, NEON and Ordinary Architecture.

"We expect Visionary Crazy Golf to be one of the most popular festival landmark projects to date," said LDF director Ben Evans in a statement issued when the campaign went live in April.

"We're sure it will attract a varied audience, from design aficionados to small children, attracted by the invention, playfulness and creativity of the course."

Visionary Crazy Golf was described by LDF as "the most ambitious" of the festival's decade-long tradition of interventions in Trafalgar Square, including a series of home-themed installations by designers including Jasper Morrison and Ilse Crawford.

Proposals for the course included a section designed by Paul Smith, who proposed transforming the Trafalgar Square steps into a series of brightly coloured cascading lanes in his signature stripes with a Neo-classical clubhouse, while Hadid's characteristic undulating forms would be applied to a two-tiered range planned between the square's lion statues.

Ordinary Architecture, led by former FAT architect Charles Holland and Elly Ward, designed a hole modelled on a cross section of one of the square's famous pigeons, where the golf ball travels through the bird's digestive system.
