This year’s Antepavilion, installed on the roof of Hoxton Docks, was designed by George Gil, an architect at Dowen Farmer, in collaboration with RARA (The Redundant Architects Recreation Association) and Luke Tannenbaum. They won the commission in an open competition last April.

The client, arts and architecture charity Antepavilion, previously won a planning battle with Hackney Council over the right to host artworks on the roof of the docks.

This year’s brief asked entrants to consider the three core considerations – permanence, size and attachment – enshrined in case law as the tests for what constitutes ‘development’ and so requires planning consent.

With a £15,000 construction budget, the structure consists of a 4.8m-diameter freestanding ‘moon’ made of plywood and stainless steel, designed to change shape or ‘shapeshift’ depending on the viewer’s position along Regent’s Canal – reminiscent of the changing phases of the moon.

Moonument was prefabricated in 19 segments at RARA in Clapton, Hackney, an open-source workshop and co-working space that provides a testbed for prototyping and making in collaboration with skilled makers. Each module was laminated with its own bespoke curvature in layers of plywood, and faced in 0.9mm stainless steel. These steel ‘fins’ are designed to throw distorted reflections of the sun, sky and water of the dock below during the day and be backlit and animated by a projection at night.

Architect’s view

Designing and building Moonument was a hugely rewarding learning experience as a young architect. Past Antepavilion commissions captured my imagination as a student, and it’s a privilege to have completed the latest artwork, encouraging playful public engagement on the well-trafficked Regent’s Canal.

Moonument was originally conceived as an otherworldly lunar illusion of reflections floating over the canal and the recently reinstated SHARKS! The months taking the winning idea to physical completion have been a lesson in how the realities of and logistics of construction can actually hone and provide greater meaning to the creative process. Methods of making can themselves reinforce the artistic intent of the abstract story the concept seeks to tell.

One such example of this was overcoming the challenge of building 19 bespoke laminated plywood modules within tolerance so that each module nested perfectly onto the next. This was overcome creatively by devising a jig table whereby the bespoke curvature of each module could be translated efficiently from the 3D Rhino model to reality. It was inspired by the many boats and canoes that pass the site daily on the canal. This also made it possible for the vast majority of the build to be carried out off-site by myself and Part 2 student Luke Tannenbaum.

I’m grateful to the competition for providing an outlet for designers to bring ideas for experimental structures and artworks into reality. Opportunities for this often seem few and far between for young designers.

Client’s view

The Antepavilion commission has been running for 10 years and is the creation of the long-established Antepavilion artists’ studios organisation. It aims to foster hands-on construction and craftsmanship at the interface of art and architecture by providing facilities, financial support, and public display opportunities.

Many winning entries have been displayed at the home of Antepavilion on the Regent’s canalside in Hackney. More recently, our SE1 site, close to Elephant and Castle, has been available as an alternative public display location.

Apart from the essential principles of the competition – self-build, low-budget construction, and public display – each year has a specific brief, always for loose interpretation. Moonument met both the general and specific briefs, the latter requiring a strong public presence and a work that served somewhat as a war memorial to the planning fight Antepavilion had for many years with Hackney Council’s efforts to close it down. Among Antepavilion’s public objectives is resistance to authoritarian, over-prescriptive and under-imaginative planning control.

George Gil’s entry, in collaboration with RARA, chimed well with these objectives. He is a young architect with strong knowledge of materials and how to work them himself. Moonument is visually striking – particularly at night – for the many people who walk, cycle, and boat along the Regent’s Canal. The lunar theme has many resonances, especially in relation to the legal tenets planners use when alleging unauthorised development under Section 55 of the TCPA: size, permanence, and attachment.

The 2026 iteration of the Antepavilion competition will be announced soon.
