Landmark House was constructed around 2005 and comprises an end of block, modern, purpose-built office building of circa 8,500 sqft arranged over 3-storeys plus mezzanine level.
The modern architecture, namely the angled walls with grey steel cladding and feature glazing makes Landmark House one of the standout buildings within Gasworks, lying comfortably with the nearby historic redbrick buildings.
The common areas of the building comprise a stairwell, 8-person Kone passenger lift, shower at ground floor and two bathrooms on each floor. The common areas are modern with painted white walls, grey floor tiles and wooden handrails.
The 2nd floor and 3rd floor mezzanine of the building are currently occupied by Ofcom.
