Adding a aluminium outdoor gazebo to your outdoor space should be carefully thought out because it can often look contrived and awkward or out of place. When planning any garden structure, try to incorporate architectural elements or features of your house for harmony and continuity. Also be aware of design considerations such as:

Scale and proportion: Does the size and shape of the proposed gazebo fit in your yard so that it's neither too big or too small for the location?
Style: Does it blend with your house and other structures on the property?
Materials: Are materials like stone, wood, and iron used elsewhere on the exterior of your house?
Location: A gazebo might be a destination, an escape, or be a place that frames a beautiful view.
Additional hardscape features, like paths or walls: Do the materials and shapes echo those used in other parts of the yard or exterior of the home?
