A slatted timber garden seat resting on concrete blocks


Outdoor bench seats can be really expensive - so why not try making your own? All you need are some Besser blocks and a piece of panel fencing. Yes, it's THAT easy.


1Get all your gear ready to go

We're using besser blocks to support our bench. These can be store bought, or you can reuse old blocks you have lying around. For the seat, we're using a piece of Merbau fence panel. This ready-made fence panel is great as it's the perfect day bed size – but the sky's the limit! Head in store to check out the range of wood/planks – and get creative.

2Measure up

After you've purchased all your materials, measure up where you want your bench seat to go. Start by measuring how long your fence panel is (width and length), then mark out the corresponding length on the surface you'd like to place your bench seat. We opted for a patio – if you're putting yours on grass you may want to make sure it's level by putting down some support pavers first.

3Place your concrete blocks down

You'll probably want to wear gloves for this bit – these concrete blocks are heavy and rough around the edges, so try to protect your hands. We are using six blocks across the distance of the fence panel so that the weight is evenly distributed.

4Glue your concrete blocks together

We want our bench seat to sit high off the ground so we're stacking two cement blocks on top of each other. Secure these using liquid nails and a caulking gun – just run some across the top of your bottom block before placing the second on top. Wait a few hours for it to dry.

5Place your fence panel on top

Grab your fence panel and place it on top of your besser blocks – and you're done! If you know that's where you want your bench seat to stay indefinitely you may want to glue your fence panel to the blocks, but this is by no means necessary. If you're renting, or likely to be moving at some point, keep the panel separate to make it easier to move.

Health & Safety

Please make sure you use all equipment appropriately and safely when following the advice in these D.I.Y. videos. You need to be familiar with how to use equipment safely and follow the instructions that came with the equipment. If you are unsure, you may feel it is safest to consult an expert, such as the manufacturer or an expert Bunnings Team Member.

Grave health hazards are linked to asbestos, which may be in homes built up to 1990. Health hazards may result from exposure to lead-based paints in older materials and copper chromium arsenic (CCA) treated timber. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer. You can also use a simple test kit from Bunnings to indicate the presence of lead-based paint.
