Rooftop Greenhouse Agrotopia, Belgium
With its faceted glass frontages, monumental entrance staircase and stacked functions, Agrotopia gives a striking, architectural face to horticulture on the city’s rooftops. Through innovative water recuperation and by reusing urban waste heat, Agrotopia enters into a circular symbiosis with the city.

Agrotopia was constructed on the roof of the REO Veiling headquarters: the logistic heart of West Flanders for fruit and vegetables. With a spectacular view across the expansive landscape and the city, urban horticulture atop industrial rooftops is afforded a prominent place in Roeselare’s skyline.
“Together with the clients, Inagro and REO Veiling, we have realised an ambitious building with numerous innovations. A single building featuring different climate zones, sustainable and economical use of space, research into leafy vegetables and fruit vegetables in the city, opening up the rooftop to a public function, circular use of space and energy, to name but a few.”

Building for research and education
In the 9,500 m2 building, high-tech research facilities for the cultivation of fruit and leafy vegetables are surrounded by an educational trail for the general public. In four different climate zones, the cultivation of tomatoes and lettuce, but also peppers and strawberries, can be followed.
“Agrotopia as a test case: building a greenhouse atop an existing building has never been done before on this scale and it presented many opportunities and challenges. The integration of the steel greenhouse with the concrete substructure and complex installations has
resulted in a true public building with exceptional architectural quality for the city of Roeselare.”
Niklaas Deboutte, META architectuurbureau
One of the challenges was to reconcile the needs for research facilities in a greenhouse, and therefore a warm and humid environment – with the requirements for visitor facilities. In Agrotopia’s greenhouse climate, it is not only plants that must thrive; it is also a place where people come to learn and work.
“To achieve this, box-in-box spaces were created for research and education with a climate adapted to people. For the public spaces, fogging is used to temper the wind chill on hot days.”

Transparent sculpture
Agrotopia is a proud, transparent sculpture of steel and glass, which underscores both its agricultural and its public function. To this end, the architecture is composed of a slender greenhouse construction that stands out against the sky and rests on the concrete base of the crate sheds.
The entrance, with a broad ascending staircase, leads to the urban horticulture square in the heart of the building where the visitor facilities are located. A double-height greenhouse for innovative vertical cultivation can be found in the façade greenhouse along the ring road.The foot of the double-height greenhouse stores the rainwater from the roof,which is then used to irrigate the crops.
The entire building consists of one standard greenhouse with diffuse glass. The greenhouse on the two cantilevered building heads owes its striking appearance to the expressive, faceted façades in transparent glass. On the entrance side, it forms vertical glass bay windows to which specific sunscreens could be added whilst also preserving the interior and exterior views. On the west side of the façade greenhouse along the ring road, the horizontal faceted construction guarantees a good incidence of sunlight for the crops and a reflection-free view at ground level.
“With Agrotopia we have differentiated and perfected the standard Venlo greenhouse.”

Sustainable and economic use of space
The increasing and urgent need to use space as sustainably, efficiently and economically as possible has created a growing trend for urban agriculture, especially as a way of activating residual space in the city. In Agrotopia, two previously independent worlds – architecture and agriculture – are united in a single building dedicated to urban agriculture.
With Agrotopia, we have created a unique location for practical research and the development of innovative techniques for greenhouse and urban agriculture. At the same time, this is the ideal place in which to conduct large-scale and professional research into the emerging field of urban horticulture.
Thanks to the proximity of REO Veiling, where the growers convene, we strengthen the link between research and practice. We also want to use a visitor corridor in the greenhouse to give the general public a better understanding of greenhouse horticulture and contemporary agriculture and horticulture.”
Mia Demeulemeester, Chief Executive Officer, Inagro
Circular water and energy use
Not a drop of water is lost in this building. When irrigating the plants, the run-off is recycled and reused. The same applies to energy: the greenhouse is warmed by the surplus heat from the Mirom waste incinerator. In short, Agrotopia exists in a circular symbiosis with the city.
“Agrotopia: where the urban farmer of the future is trained. The next generation urban farmer will not only learn how to grow both leafy and fruit vegetables; they will also learn how to work with new technologies and business models.”

van Bergen Kolpa Architects
Van Bergen Kolpa Architects designs architecture for food. The office works internationally and focuses on clients, stakeholders and innovators who aspire to create sustainable buildings and cities, both now and in the future. Central to the methodology is the formation of a circular balance between programme, urban landscape and natural resources. Van Bergen Kolpa works in multidisciplinary teams of experts on construction projects and urban planning schemes such as Vertical Farm in Hengshui, China, the Metropolitan Food Valley in Beijing, the Foodexpo building in Doha, Qatar, and the Greenport West-Holland.
The company’s projects have been exhibited and published worldwide, including at the Sao Paulo Architecture Biennale and on CNN’s World News channel. In recent years, the practice has received various awards and nominations, including the Prix de Rome, the Charlotte Köhler Prize, the World Architecture Award and the Hedy d’Ancona Prize. The office was founded in 2000 by Jago van Bergen and Evert Kolpa.

META
For META, architecture is a craft that requires professional skill. This means that each design problem receives a fully elaborated solution that doesn’t simply mean taking the easiest route or staying on a well-trodden path. The designs can therefore sometimes be capricious or offer resistance, or can even cause friction, but they always make building simpler, even obvious.
As a designer and builder, META take the liberty of being ambitious. To design a building as perfectly as possible so that its function and usage can be easily adapted. To allow a building to write its own unpredictable history and future through a design.

Inagro
Every day, farmers look for new techniques to make delicious products in an efficient and sustainable way. Inagro has been helping them with research and advice for 65 years. The research centre’s core activities are to provide scientifically substantiated, practical research and to share knowledge with stakeholders in the agricultural sector. Inagro achieves this ambition for glasshouse and urban horticulture in Agrotopia. It cooperates closely with the stakeholders to implement the research results in the field today and at the same time move towards the agriculture and horticulture of the future.
Flemish Government Architect
Agrotopia is one of the Flemish Government Architect’s Pilot Projects for a Productive Landscape. With these projects, the Flemish government architect places the focus on social challenges that demand innovative building projects. The aim of a pilot project is to establish cooperation across different sectors so as to facilitate architectural and social innovation. The strength of these pilot projects is that theories are directly tested against reality.
