“They broke the mold on how to create for the long term with a contemporary language. It raises the issue of the importance of accessibility to fresh produce in the inner city. This strikes such a great balance of design, scale, and economy that it makes a good model. And it’s great that it’s so visible right downtown. ”
—2012 Professional Awards Jury

用现代的语言打破传统的束缚，用伟大的设计平衡规模与经济，在城市中提供新鲜的农产品。太棒了，对城市腹地极其有价值。

This .425 acre garden fills a parcel of city land left vacant after the 2010 demolition of the historic Lafayette Building in downtown Detroit. Just a one block walk from Compuware headquarters, adjacent to the financial district and bordered by the Detroit Federal Building and the renovated Westin Book Cadillac Hotel, this vegetable garden fills a busy and highly visible urban setting. The loss of the Lafayette building left the city looking to future development and city inhabitants unhappy with a depressing empty lot. Lafayette Greens is a cooperative effort between private and public sectors resulting in a positive and productive interim use of a vacant parcel in the city.

Design Intent
The client approached the landscape architects with a conventional community garden concept of raised wooden beds, bark mulch pathways, and a space for children. As design development progressed, the program for Lafayette Greens evolved to include the use of sustainable materials and practices wherever possible, spaces for public use and enjoyment, future and ongoing public art projects and a fun educational Children’s Garden. The designer looked closely at the relationships between the garden and the surrounding urban context. In spite of the current enthusiasm for urban agriculture, there are also many reservations and questions about whether this type of activity is appropriate in the city and urban living experience. Aesthetics, environmental concerns, productivity and economics all need to be addressed. The landscape architects were intent on re-imagining how urban agriculture could look and function in a site specific way; in this case, the community garden as a sophisticated urban space, productive and multi-functional as public space, green space and community space.

The overall design of Lafayette Greens was shaped by the site analysis. Raised vegetable beds were oriented for optimal sun exposure based on sun angle studies, especially critical in an environment of tall buildings. Due to its unusual shape, pedestrians had to go out of their way when passing through the area or cut across the vacant site. A wide Lavender Promenade now carries people along this desire line. Pedestrians can move through the space quickly, rest on a bench or enter the garden and explore over 200 types of vegetables, fruits, herbs and flowers. A variety of seating is provided throughout the garden to encourage public use of the space and provide respite from the surrounding busy city streets which offer virtually no outdoor seating. The use of fragrant Lavender, with its documented ability to induce calm, to line the public passage through the site reinforces the regenerative and restorative function of the garden in a bustling city environment. Views from the surrounding buildings and parking decks led to a strong visual statement in plan view. The geometry of the spaces in the garden reflects the structural order of the urbanenvironment. Drawing from architecture, urban form and agriculture the design of the long rows of steel beds are at once urban and industrial, and yet organic and natural, overflowing with plant life. Because of challenges presented by the awkwardly shaped property, the steady rhythm of raised beds was arranged within the golden ratio to impose a calm order on the site design.

To accommodate 4 feet of grade change across the site, the vegetable beds rise out of the ground plane as it falls gently from Lafayette Blvd to Michigan Ave. This gentle but dynamic solution energizes the wide, flat, expanse of space and permits easy access to planting beds for all kinds of gardeners and visitors. A continuum of bed heights from 8” to 40” high along the 70 foot long planters allows toddlers to get close to the action at the low ends, while the taller areas are barrier-free and back friendly.
Sustainability
Stormwater Management and Water Usage The garden is an opportunity to showcase and demonstrate sustainability. An urban bioswale catches and slows stormwater runoff. With informative signage, it also catches attention and raises awareness about bioswales and water issues in the Great Lakes region. Planted between two gabion curbs, a hedge of Redtwig Dogwood are sheared into a clean architectural bioswale appropriate for a city street. 70% of the site’s surfaces are pervious: gravel, lawn and planting beds. Drought tolerant Fescue lawns and a high efficiency irrigation system including adjustable driplines in the raised beds conserve water.

Materials Re-use
A gabion curb filled with concrete rubble frames the site and bio-swale, broken sidewalk pieces are re-used as pavers, the garden sheds are clad in reclaimed pallet wood and salvaged doors. Repurposed food grade steel drums are planters in the Children’s garden.

Urban Bio-diversity
More than 200 plants: vegetables, herbs, flowers, heirloom fruit trees, vines, berries, a native species short orchard meadow and a bioswale add diversity to the urban environment and habitat for pollinators.

Efficient Organic Growing Methods
The entire garden is managed organically. Bio-intensive raised beds with drip irrigation are highly productive with a potential 200-400% increased caloric production vs conventional gardens, consume less water and require low energy inputs.

Education and Community
Lafayette Greens is unique as an urban garden in that it is a public space that is participatory. Anyone can take part in planting, tending, harvesting, learning and teaching. It is a place to meet, participate in the conversation about local food systems, share food and experience the rhythm of the seasons. The landscape architects made it a priority to create spaces in the garden to accommodate events, workshops and gathering. Education is inherent in the very act of growing food – from science, ecology, history, and nutrition to issues surrounding urban agriculture, public health and food access. Although the vegetable beds at Lafayette Greens have the potential to produce upwards of $10,000 worth of produce in a growing season, the location and visibility of
the garden bring the educational value of the space to the forefront. The garden is a showcase for urban growing techniques from bio-intensive methods, organic pest management, SPIN Farming and the French Potager tradition of the kitchen garden planted for its beauty as well as its productivity.

With the Compuware daycare nearby and parents volunteering in the garden, The Children’s Garden is an important component of Lafayette Greens. In a garden of strong angles, geometric shapesand steel, this space is round and friendly, signaling it as a special garden within a garden. A protected space enclosed in a circle of thorn-less blackberry bushes and sunflowers, it holds amaze of round colorful planters. Small and circular, the repurposed juice barrels and galvanized fire rings set at various heights are easily accessible to children of all ages. Although this garden is only 38 feet in diameter, its themed planting scheme offers a rich educational experience in a small space. The Landscape Architects created a planting plan with names like ‘The Petting Zoo’, ‘Purple Pandemonium’ and ‘The Salad Bar’, that fill the planters with colors, textures, tastes, scents, forms, and plant names from A to Z.

Three garden sheds, named Charles, Howard and Crane after the Detroit architect who designed the Lafayette Building and 250 movie palaces across North America, including the iconic Fox Theater in Detroit, were designed by the Landscape Architects to fulfill multiple functions. As garden sheds they hold and store tools and supplies. The sculptural, whimsical forms add a vertical focal point to the space and serve as the first of several planned art installations in the garden. The sheds define the edge of the garden and enframe the open lawn area, creating a buffer along the busy street.

Lafayette Greens is an example of how Landscape Architects can set the standard for urban agriculture design that enhances the urban experience and highlights the interrelationship of landscape, food systems and the built environment. With food security becoming an increasingly important global concern, the growth of urban agriculture is inevitable. Landscape architects are uniquely equipped to design productive landscapes in our cities that are beautiful, functional, sustainable, efficient and fully integrated into city living in innovative and surprising new ways.
