Abstract: A portable and adjustable shelter for sheltering vehicles, cars, or goods or people is disclosed. The shelter includes a plurality of legs, each leg having a column base attached to a first column which is attached to a second column. The first column is vertically adjustable relative to the column base, enabling the height of the legs to be adjusted. The second column has a projection for attaching to a roof. The roof has a pair of truss assemblies each configured to attach two legs, and each having an upper surface and a lower surface. The lower surface defines a plurality of spaced apart receptacles sized to receive the projection of the second column to secure the roof to the legs at various positions, enabling the user to alter the width of the shelter.
