Funicular Folly

The Funicular Folly is a slick and solid brick tent, created by Rae Moore, for Body & Soul, an annual music and arts festival in the Irish countryside. It is the first installation of its kind in Ireland, and will remain a permanent feature on the grounds of Ballinlough Castle, Co. Westmeath. The project aims to demonstrate the power and generosity of architecture as a contemporary art form
Ambition
From the outset, Moore’s ambition was to create a highly innovative and finely crafted structure, to captivate and excite the festival’s 15,000+ attendees, and get them ‘buzzed’ about architecture.
Concept
In response to Body & Soul’s call for submissions that would ‘subvert everyday norms’, the Funicular Folly gives a forceful new life to a common building material—brick—by adopting a tent-like form that echoes its festival habitat.
Innovation
This innovative brick structure is the first of its kind in Ireland. Designed by Rae Moore, in collaboration with Arup (Engineers), the project combines ancient construction techniques, contemporary craftsmanship, and the latest digital design technology.
Tradition
Following the tradition of the architectural folly, this installation is a curiosity and a landmark, providing an intimate enclosure within its great brick belly.
Form
The structure is based on the plan of a 6m equilateral triangle—a symbol of femininity and queer cultural identity. The dome rises from this geometric base to create an asymmetrical space that addresses a main pedestrian pathway through the festival woodlands. A small oculus casts light through the interior.
Budget
The festival’s budget for the installation was just €400. Moore had the additional challenge of assembling a specialist design and construction team to collaborate on the build. The total cost of the project was just under €65,000; however, all materials and skills were generously donated by passionate and expert individuals from across the Irish construction industry.
Construction
Using a technique known as the Catalan or timbrel vault, the structure was built up using three thin layers of brick tiles and cement, cross-laminated to create a cohesive shell. To allow the brickwork to take shape, a complex temporary timber guide-work was digitally prefabricated using CNC technology and assembled on site.
Craft
The brickwork was carried out by a highly skilled and experienced team, who typically specialise in laying two-dimensional curved brick walls. The brickwork includes herringbone joints and a triangular pattern that is expressed at the dome's apex.
Structure
With a total continuous thickness of 80mm, this freestanding curved form achieves perfect equilibrium through an idealised or natural curvature, known as a catenary curve. The structure disappears into the ground, where it sits on three concrete pads that are tied together with slender ground beams.
Cultural Value
This project exemplifies the joy and capacity of architecture, free from the contemporary commercial constraints of developer-driven construction culture.
