Like the earlier van version, the "Imp estate" was based on the two-door car, with the roof raised by 4 inches (100 mm) to provide a large carrying space above the engine bay, giving the car a square boxy look. The unusually flat roof was reinforced with stiffening ribs and supported on the inside of the vehicle with "synthetic foam noise-deadening material". When compared to the Commer badged panel van from which it derived, the Husky body also had extra stiffening at the rear window apertures.
