 The Garden Lobby is the main thoroughfare in the business areas. They're seating here for informal meetings, and through the window wall at the end you might just be able to glimpse the garden for which the lobby is named. Up above are unusual windows and light floods into the Garden Lobby through them. The lead architect envisaged the building as a green leaf tree branch, and perhaps this is the canopy of leaves. Cut out in the panels above our heads are a decorative map of Scotland. And in behind those panels are the vent flaps which bring air into the Garden Lobby. They're part of the Parliament's natural ventilation system. The north wall of the Garden Lobby is the rear wall of the 17th century Queen'sbury House. That's the oldest part of the campus. Many Parliament teams have desks here and they provide information on different matters to MSPs and staff. The Garden Lobby stairs lead to the debating chamber and they frequently feature in television news reports. There's a backdrop to the many interviews which journalists conduct with MSPs here.
