Where to position pergola posts on a patio

Post positions shape the way people move

Posts are usually noticed as part of a pergola's appearance, but their positions also organise movement. A post near the edge of a table may be unobtrusive when the chairs are tucked in and awkward when somebody is seated. Another may interrupt the route from a kitchen door to the garden. Draw these everyday movements before choosing a symmetrical position solely for the elevation.

A TTH Pergola layout should show the post footprint, the surrounding finished surface and the intended foundation position. Those are related but not identical pieces of information. Existing paving does not tell you everything about the support beneath it. When reviewing tthpergola.com photographs, use the base images to understand the visible connection, then ask how the proposed site will accommodate the actual support. Furniture mock-ups or simple floor markings can help reveal circulation conflicts early. Symmetry remains a useful design goal, but it should work together with the structure and the route people naturally take. The best-looking position on a drawing is less persuasive if it forces people to walk around an obstacle every day.

Draw movement before structure

The best-looking post position is not always the most useful one. Begin by drawing the path from the house to the terrace, the furniture arrangement and any route to the garden. Include chairs when pulled out and doors when open. Posts should be evaluated within this occupied layout rather than against an empty rectangle. This reveals conflicts that can be difficult to see in a wide-angle scene photograph.

Confirm the supporting location

A convenient position on the plan still needs a suitable installation arrangement. The appearance of tiles or decking does not establish what lies beneath them or whether the location can accept the proposed fixing. Mark drains, inspection covers and known services. Have the responsible installer review the supporting conditions and foundation requirements. Do not shift or omit a post after approval without asking how the change affects the complete system.

Coordinate the edges of the space

Post locations also influence side screens, glass panels and drainage outlets. Review each side as a complete opening, including access for operation and cleaning. Where the pergola sits near a wall, check handles, downpipes and exterior fittings at more than one height. Ask for a drawing that identifies overall roof dimensions and post reference points separately. Clear dimensions make it easier to verify that the planned space, rather than only the roof outline, will fit. Where two positions appear equally convenient, ask for both to be assessed against the supporting conditions and accessory interfaces before choosing on appearance alone.

• Protect the principal walking route.
• Check chair pull-out and door opening space.
• Confirm accessories before approving the final post layout.

Can a post be moved after the pergola is ordered?

A changed post position can affect the frame, connections and foundations. Treat it as a design revision that needs confirmation, not as an ordinary on-site adjustment. Resolve the intended footprint before approving manufacture.
