In a small living space it is necessary to make sure you have your priorities set straight. You need to decide from the beginning how you want to manage the space you have so that you are happy. Living in a condominium is definitely different from living in a house when it comes to space. In a condominium, you may need to get more compact furniture that is multi-functional. Storage and recreational space can also be limited.
Having a garden in a condominium is not possible in most cases but having a version of this is doable. If your condominium unit has a balcony for example, you can definitely set aside a space for your potted plants. Researching the kinds of indoor plants available in your area or seeing which veggies can grow in a pot is one way of making your green landscape happen.
In short, with just some research, priority setting, and flexibility, you can create your own little green area.
