To give you the best recommendations, could you describe the space or upload a photo?
Depending on what you have in mind, “this space” can refer to very different things. Here are a few quick ideas based on the type of place:
If it is an empty corner in your home: you could create a reading nook with a comfortable armchair, a coffee corner with an elegant shelf, or a small urban garden if it benefits from natural light.
If it is a small room: a well-organised workspace or home office, or an open dressing room with mirrors to create an impression of space.
If it is an outdoor space (balcony or terrace): a relaxation corner with pallets and string lights, or a vertical garden to utilize the walls.
What type of space are we talking about and what do you want to use it for (relaxation, work, storage)?
