Decking Designs on YouTube

A basic introductory concept for a client in St Albans. They have an existing decking platform, dated and past its best. This is shown by the first sketch in the series.

It needs a redesign which fits the beautiful garden it sits in. Karl has offered a simple approach to this concept and by keeping within the clients brief of creating curves… do you think he’s nailed it?

Decking Structure in Design

There are many methods to create a decking frame for your platform, the most common being timber. 100 mm x 100 mm posts in Use Class treated timber is the most common dimension with options up to 150 mm x 150mm sometimes being used.

Recycled plastic or HDPE as its known is a sensible option for your post supports as this will never rot. Steel PFC (Parallel Flange Channel, similar to an RSJ) is also sometimes a good option for more heavy duty applications.

The main structure is Treated timber and a close second is HDPE. Aluminium is rapidly becoming the third option with many manufacturers now offering this as a rot free solution.

Presenting your design to your client.

There are many options for presenting and these days some clients expect a massive production with more than a simple sketch. 3D walk throughs and animated rendered videos… Thats fine if you are commissioned for this level of work.

A simple out line sketch is a starting point and gets the message across well. If you do a structural design you should keep this as part of the warranty, if there is an issue years down the line you will be covered if your design is up to regulatory standard… If you are unsure what to expect  contact your local professional Landscaper from the APL (Association of Professional Landscapers). Karl Harrison Landscapes Decking experience is vast and Im sure he’d like to offer his services.
