The building itself was designed to look and feel like a ship inside. All the offices and passages are made up with bowed windows and light oak finishing. Each floor looks identical to the others except the ground floor which houses the main courtyard with ship-like metallic sails suspended overhead. The courtyard is decorated with trees and two shallow baths of water.

The offices at Portcullis House are generally in sets of two sharing a common bay in the centre. Each floor is unofficially allocated to a different political party so that generally MPs with similar politics are kept together. The first floor houses a number of conference suites and committee rooms, which are named after famous politicians Betty Boothroyd
