Imagine the person peering over this hedge to see a new construction taking shape. Might they be intrigued, perturbed or annoyed? Now imagine that the owner of the house being renovated is a rival of the witness. How might their history colour responses?
Now broaden your viewers’ understanding of what they’re seeing, based on earlier conversations or arguments. Rather than an extension, could the item being built be a spaceship or time travel machine? Remember that in the realms of fantasy, these can be constructed any shape and from any material.
Or could the builders be the focus of the witness’ attention? Is there one of particular interest? Why?
Can you weave in the emotions and backstory through your protagonist’s reactions and behaviour rather than telling your reader?
