“Gap Filler aims to temporarily activate vacant sites within Christchurch with creative projects to make for more interesting dynamic and vibrant city.”
As we began our search for successful ways to reconstruct vacant lots, we came across an organization called Gap Filler and the work they have done within Christchurch, New Zealand. The strategy of this organization was to build community awareness and overall attitude towards the vacant lots by turning them into temporary dance floors. In order to make this happen, Gap Filler selects certain vacant lots throughout the community and lay down temporary dance floors for the public to utilize. In order to work the dance floors you have to insert a coin into the available machines and then it allows you to plug in whatever music people prefer. This not only draws attention to the vacant lots, but allows for public performances and positive energy amongst the people. The dance floors not only serve to rebuild the community but also give a kick start to the lots by drawing attention to it. This allows people to want to be involved by contributing to more and ultimately paving the way to revitalization without payment. By being temporary, the dance floors do not cause long term damage and erosion to the soil or land itself. The money raised by the dance floor can be donated to the city, or used by the company themselves, to clean up the vacant lots and replace it with a variety of more permanent structures such as playgrounds and gardens.
By creating these temporary dance floors the vacant lots changed the atmosphere in the community as well as the motivation, which these organizations said is the first step to success is renewing vacant lots. The goal of this strategy was strictly to unite the community and bring awareness to the land and show all of the potential it has by ringing life and energy to the land.
The two figures above show the differences between the runoff levels of hard surfaces and fresh land. There is 45% more runoff in the city, where there are hard surfaces. In relation to the temporary dance floors in New Zealand, it is better to create a temporary solution instead of a permanent hard surface because it conserves rain water and produces less runoff.
When it comes to costs and the coordination of this program, it is generally less expensive than other activities because the main purchase is the dance floor which is completely made from recycled material. Gap Filler also receives grants as well as financial support from local community organizations such as art councils and is operated mainly by a volunteer based staff. By using the volunteer force you can gather people who are directly interested in the use of the lots and improvement of the community. One option could always be to make an abroad option for Wittenberg students to travel to areas such as New Zealand and participate in such activities. Another option could be for Wittenberg students to team up with local Springfield Elementary schools and work something like this up in our own community to host an event and bring awareness to the vacant lot. This gives us the opportunity to raise money from the coins collected from participants and then be able to move forward to preserve the soil in the lot or build upon it with things such as community gardens or playgrounds.
Below, the two figures relate to our topic by showing other lots and locations of the dance floors and also the large numbers of the land that has the potential to be used.
In recent years, Chicago has started designing and implementing rooftop gardening. Not only are rooftop gardens aesthetically pleasing; but they save energy, keep buildings cooler, and can help preserve the life of the roof. Rooftop gardening replaces the dark tar roofing, which lowers temperatures and reduces air pollution.
Essential Layers of a Rooftop Garden
Instead of the plants merely sitting on top of the roof, some gardens become the roof. These “green roof systems” provide drainage and nutrients, and can be intensive or extensive. The extensive gardens are lightweight and low maintenance, while the intensive gardens closely resemble ones seen on the ground.
Planning and preparation for a rooftop garden is an extensive process that needs to be carefully done, and there are several factors to consider, such as: the condition of the roof and how much it can hold, how you are going to access the garden, how much the garden will weigh, how much the garden will cost, how to irrigate your garden, how to be sure water is properly drained, and how it will be designed.
Estimated costs of installing a green roof start at $10 per square foot for simpler extensive roofing, and $25 per square foot for intensive roofs. Annual maintenance costs for either type of roof may range from $0.75–$1.50 per square foot. Depending on the size of the garden, the amount of people needed to build the rooftop garden varies as well as the time commitment. You should be able to dedicate at least 1 hour a day to the rooftop garden to ensure it has enough water and to prune the plants.
While the initial costs of green roofs are higher than those of conventional materials, building owners can help offset the difference through reduced energy and stormwater management costs, and potentially have a longer lifespan of green roofs compared with conventional roofing materials.
Green-roofs are rapidly becoming popular and Chicago already has 359 rooftop gardens established. The Urban Heat Island Effect is the temperature between a city and the area around it because of the asphalt and dark surfaces that emit heat, and the rooftop gardens help battle this effect. They lower the temperatures by replacing dark roofs and they add more oxygen to the atmosphere.

Wittenberg students and the students from the community can turn abandoned buildings into something useful and beautiful. Some abandoned buildings cannot be torn down easily because of cost, time, and the labor involved. Instead of choosing a an empty lot, we could use the building on the lot as a storage place for the garden materials, turn it into an indoor garden, or find a way to make it functional for the community. We could use everything on the lot by making use of the storage the building provides, as well as making a rooftop garden. This project could have several parts for the students to be involved in. Along with the garden, the students could help paint the building and make it a fun, safe place for them to go.
