The Plymouth obelisk is designed as a Pillar support for our 'Open Plan' garden archways & pergolas systems. 'Open Plan' means requiring NO waist height side support bars along the structures length. This can be very convenient for many reasons plus LARGE spacing gaps are possible between the obelisk pillar supports down the length of the Arch or Pergola design structure. This can be a good cost saving especially with very long designed units.
Arch top widths up to 2500mm can be supplied using this Open Plan System. It mainly depends on the choice of arch top design curve shaping. *Extra wide arches are possible, but can incur a significant extra transport cost.
Spacing gaps of up to 3,000mm between pillar support along the length of the Archway or Pergola can be supplied with our 'Open Plan' design system and can be particularly useful where a long length of 'side access' is required.
An extra special design feature that can also be supplied on this ironwork system is that differing pillar support heights can be supplied if your garden has a significant 'Sideway' ground slope.
