Once the space is selected, you can start contacting, talking, presenting your idea to the agents operating in the area and collecting suggestions from them. Agents may be the space owners, local authorities, potential partner organisations, informal groups, or neighbouring citizens.
The discussion with them can be iterative, in order to involve them as much as possible in the evolution of the space and nurture its growth with additional stimuli and relationships.

You can work with your team on this plan to build partnerships: starting from locating the stage that you are at, then identifying the people that you need to work with and finally structuring the relationships in order to ensure longer commitment.

You can plan some pre-opening or collaboration events which can be loosely structured (parties, dinners, etc.) or more structured formats to enable connections between future members. Imagine the events as if you already had a space.

The more these activities are regular and open to the public, the more your space will be embedded in the area. On the other hand, if you want to attract a particular target, remember to invite some key actors and node organisations who can be relevant for that target.

Try to offer a glimpse of what the space will be, as well as of its vision, when proposing pop-up initiatives. Remember that these initiatives can also take place in other locations, not exclusively in the one which will host your collaborative space at the end of the meanwhile time. Choosing other locations for this kind of events can also be a good opportunity to strengthen relations with partner organisations and partner spaces.

In these events, create settings where people will have the chance to meet each other and have shared experiences. Remember to close all the events with a clear invitation for the next steps and ask participants to share their experience within their networks.

Take a look to get inspiration on tactical urbanism from some of the best tactical urbanism experiences. Also, you can get inspiration from several examples of meanwhile and temporary uses.

How does the type of agreement influence the Business Model? The kind of agreement you sign will definitely influence your business and revenue model. Re-define it according to the conditions agreed with the space owner and other actors who can influence its uses.
Remember the importance of setting agreements that can be flexible enough to have room for change (in example, change of services offered or need for larger spaces if additional uses arise or if the community grows).
