Custom Design Planters

Custom Design Garden Large Planters, made from Accoya with 25 year timber guarantee.


Custom Design Planters, we offer wooden garden planters with panels machined with your custom panel design together with optional finials to complement your design. All planters are built to order and made any size using premium quality timber, liner and paint together with mortice and tenon construction to ensure that your planter is built to the highest quality.

We use Accoya, a premium grade sustainable and environmentally friendly timber for the frame, base support structure and finials. The planter side panels and sectional base are made from MEDITE® TRICOYA® EXTREME Engineered Wood Panels. Both have exceptional durability and dimensional stability and a 25 year timber guarantee against timber rot or decay. In addition, Accoya and Tricoya have exceptional dimensional stability, with minimal expansion or shrinkage than other timbers, this results in paint finishes lasting much longer.

Our planters are made using 70mm x 70mm legs with 70mm x 60mm rails, this ensures a strong heavy duty frame and base, in addition to ensure maximum strength, the planter side panels are also fully rebated on all 4 sides.

Large Planter - Base Construction, Drainage and Irrigation

Planter Base, for our very large planters we use the following construction method. We create a base support frame made from 70mm x 60mm Accoya fitted across and between the bottom planter rails to support a sectional base, made from 18mm Medite Tricoya Extreme board. These panels are cut to size with 25mm radius cut out at each of the 4 external and internal corners, providing drainage at all 4 corners of the planter base, together with an additional 10mm drainage gap between each of the 4 base panels creates a central drainage hole measuring 50mm.

Large Planter - Liner made from durable and environmentally friendly Butyl liner with a 20 year guarantee.

The liner is fitted for both aesthetic and drainage management purposes, this is fitted around the inner perimeter of the planter, to the full height of the inner side panels and extends 50mm onto the planter base boards. We then fit loose fitting sections of butyl liner to cover the base, which can be lifted and cut as required to provide adjustment for drainage holes and any irrigation pipes.

We offer the choice of any colour including colour matching RAL codes, using premium quality, genuine paints from Little Greene Paint Company, Farrow & Ball plus other premium paint brands upon request.

You can either order online or contact us by telephone or email to discus your custom design planters. If you order online please send us a drawing, sketch or photo of your design by email and we will make your custom planters, any size and any colour.
