While most things you can work around such as setting up a mini kitchen with microwave, toaster oven, bar size fridge, etc. You will still need to have a sink that is separate from your bathroom. It will be hard to attract clients without the basics of a home available.

As to the outdoor space, take a walk around your neighbourhood and take pictures of any park play area you can walk to. Have a plan in mind - wagon, multichild stroller, etc for how you will get there.
