Step 1 16

Saw and sand the planks

A piece of wood that is clamped down is being sawn with a NanoBlade saw.
It’s best to cut all your planks to length before you get going.
A wooden plank is being sanded down with a multi-sander.
It’s worth sanding everything down in advance to improve the appearance of your bench when it’s finished.

You need: NanoBlade saw, Multi-sander, grit sandpaper for the multi-sander, Accessories for Jigsaws, g-clamps, pocket rule, pencil, Rough-sawn planks (W: 100 mm x D: 24 mm) in various lengths, Side panels (foot supports and arm rests): 12x 760 mm, Tops of arm rests: 2x 705 mm, Seat and backrest frame: 2x 650 mm, Side rests of the bench: 2x 660 mm, 2x 600 mm, 2x 100 mm, Centre strut: 2x 190 mm, 1x 600 mm, Crossbars: 2x 1420 mm, 1x 1372 mm, Seat: 5x 1420 mm, Backrest: 13x 764 mm to 590 mm (up to you), MDF wooden boards: 700 x 750 x 4–6 mm

You need to saw a few planks to the right length for your new garden bench. Get hold of enough wooden planks with a width of 100 mm and a thickness of 24 mm. Transfer the measurements and saw them to length.
You should have all the planks in the lengths specified in the list of materials above once you’re done.

Then, thoroughly sand the edges and surfaces of the planks.

Step 2 16

Use the template

A measurement is being transferred to a large wooden board using a folding rule.
A wooden plank is being used to help draw a line on a large wooden board.

You need: pocket rule, pencil, Wooden board measuring 700 x 750 x 4–6 mm, wooden plank (at least 700 mm in length)

In the first steps, you will deal with the foot supports of your bench. Start by drawing a template so that the two side panels are exactly identical when you build them.

You’ll need a simple wooden board for the template. You can find all the measurements that you will need to transfer to the board in the diagram, which we have made available for download. You can use the planks you have sawn in the previous step to help mark out the lines.

Download the diagram here .

Step 3 16

Screw the side panels (foot supports and arm rests) together

Four oblong wooden planks are being arranged on a wooden board.
Two wooden planks are being screwed together using a cordless screwdriver.

You need: Cordless Drill, 3.5 mm wood drill bit, Screw bits, adhesive tape, g-clamps, 4 wooden planks (760 mm each), screws 4x45, the template made in step 2

Now, take the template you made in step two and position the planks you sawed to length in step one in the right places.

Then, drill holes in the four overlapping corners.

Tip
HINT
Mark the depth you want to drill to on the drill bit so that you don’t drill too deep, or use a depth stop. Then, screw the planks together.
Step 4 16

Saw off the protruding ends

The protruding ends of two wooden planks that are screwed together are being sawn off using a NanoBlade saw.
You’ll have to saw off more protruding ends over the course of the next few steps.

You need: NanoBlade saw, g-clamps

Saw off all the protruding ends. You can also sand the cut edges for an extra degree of fineness.

Step 5 16

Widen the side panels (foot supports and arm rests)

A construction consisting of four wooden planks is being turned over.
Another plank of wood is being attached to a construction consisting of several planks of wood.
Two overlapping wooden planks are being screwed together.

You need: NanoBlade saw, Cordless Drill, 3.5 mm wood drill bit, Screw bits, g-clamps, 2 wooden planks (760 mm each), screws 4x45

Now, turn the side panel over. Place two more planks with lengths specified above at the top and bottom, drill holes in them and screw them together.

Saw the protruding ends off again here so they’re level and sand them.

Now, simply repeat the last three steps (three to five) to build a second foot so your bench can actually stand up

Step 6 16

Build the side rests

Three additional wooden planks with different lengths are being placed on a wooden board.
Two overlapping wooden planks are being adjusted so they are at the right angle.
Two overlapping wooden planks are being screwed together.

You need: NanoBlade saw, Cordless Drill, 3.5 mm wood drill bit, Screw bits, g-clamps, 660 mm wooden plank, 600 mm wooden plank, 100 mm wooden plank, the template made in step 2, screws 4x45

In the next step, you will build the two side rests for the bench.

To do this, you’ll need the template you made in step two once again. Position the planks needed for the first side rest.
Make sure the overlapping ends are at the right angle.

Now, pre-drill holes into the planks, screw them together, saw the ends level and sand them off following the same process as you did before.

Repeat this process to build the second side rest. But watch out: don’t forget that second side rest is the mirror image of the first!

Step 7 16

Sand the edges

The side of a construction consisting of several planks of wood is being sanded.
As soon as you’re finished building the foot supports side rests, you should sand all the edges again.

You need: Multi-sander, grit sandpaper for the multi-sander, Schraubzwingen

You should sand all of the edges of the side panels and side rests you built in the previous steps so that everything looks neat.

Step 8 16

Pre-drill the foot supports and side rests

Another plank is being placed on a construction consisting of several planks of wood.
A wood drill bit is used to drill a hole through several wooden planks.

You need: Cordless Drill, Wood drill bit 10mm, The template made in step 2

Grab the template you made in step two once again. First, position a foot part in the correct spot and then position a pre-assembled side rest on that.

Now, drill the holes for the screws in the centre of each of the three overlapping points. However, make sure you drill through all of the planks this time.

Repeat the step for the foot part and side rest for the other side. Again, don’t forget that the other side has to be back-to-front (mirror image)!

Tip

Use a piece of scrap wood to provide stability when drilling so you don’t break the planks. The second image shows you how you should position it.
Step 9 16

Build a small central support strut

Three wooden planks with different lengths are being positioned on a wooden board.
You can also use the template for the central support strut.

You need: NanoBlade saw, Cordless Drill, 3.5 mm wood drill bit, Screw bits, g-clamps, 2x 190 mm wooden planks, 600 mm wooden plank, the template made in step 2, screws 4x45

You’ll need a small central support strut as the seat of the bench needs to be very stable. To make this, position three more planks (two small ones and one large one) on the template you made in step two. Drill holes into them, screw them together and saw off the protruding ends.

Step 10 16

Build the frame for the seat

Various parts of the garden bench are being correctly positioned on a work surface.
This image shows you where to position the parts you’ve already built.
Two wooden planks are being screwed together at the corner.
Screw the various different parts together at each of the corners.

You need: Cordless Drill, 3.5 mm wood drill bit, Screw bits, g-clamps, 1420 mm wooden plank, 2 side rests, central support, screws 4x45

Now, grab the long wooden plank, the two side rests and the central support. Put everything in its correct position on your work surface and clamp them together securely. This forms the frame of the seat.

Join the parts together by drilling holes and screwing them together.

Step 11 16

Build the frame for backrest

The frame of a wooden bench is being positioned on a work surface.
Now, stand the frame of the bench up...
Additional planks are being positioned at the sides of the frame of the wooden bench.
…secure more planks for the backrest…
Two wooden planks are being screwed together at the corner.
...and screw them together at each of the corners.

You need: Cordless Drill, 3.5 mm wood drill bit, Screw bits, g-clamps, 1420 mm wooden plank, 1420 mm wooden plank minus the thickness of the plank (22 mm in our case), screws 4x45

Now, stand the screwed-together frame of the seat up so that the backrest is lying on the work surface. Secure two more boards to the backrest to add stability to it.

Once all the planks are in the correct position, drill holes in them and connect them to the other parts using screws.

Step 12 16

Attach the planks for the seat

Several wooden planks are being positioned to form the seat of the wooden bench.
A screw is being screwed into a wooden plank. Spacers are helping you with the positioning.

You need: Cordless Drill, 3.5 mm wood drill bit, Screw bits, g-clamps, 5x 1420 mm wooden planks, screws 4x60

You now need five planks to make the seat. Position them and secure them to the frame.
Please note: Let the foremost plank protrude by about 10 mm and leave a little space between each of the other slats Use a spacer to help with this or make do with a suitable alternative.

Then, screw them all down.

Step 13 16

Attach the planks for the backrest

Planks with different lengths are being positioned to form the backrest of the wooden bench.
You should cut the planks for the backrest into the desired shape and length before positioning them.
A wooden plank is being placed between the seat and the backrest.
Position a loose wooden plank so that all the planks for the back rest stop at the same height.
The planks for the backrest are being attached with screws.
Insert screws into each plank to attach the backrest.

You need: Cordless Drill, 3.5 mm wood drill bit, Screw bits, g-clamps, 13 wooden planks in different lengths (depending on design), screws 4x45

You’ll need 13 more planks for the backrest. You can saw the top ends of the bench in different ways to suit your style and taste, giving your bench its own unique look.

First, position the two outside planks level with outside edge of the frame. Then, lay down the rest of the planks using a spacer to help.

Now, drill holes in the correct positions and screw all the slats down.

Tip
HINT
Place a long wooden plank between the seat and the backrest so all of the planks stop at the same height.
Step 14 16

Attach the foot supports

A carriage bolt is being positioned on the side rest with a hammer.
The nut of a carriage bolt is being tightened with a spanner.

You need: Cordless drill/driver, g-clamps, Both foot supports, 2 carriage bolts minimum 110 mm, 4 carriage bolts 80 mm, spacer, hammer

Now, attach the two foot supports to the bench. You already drilled the holes needed for the carriage bolts in step eight.
First, use a hammer to get the bolts into the correct position and then tighten them with a spanner.
Use the longer bolts at the top and the shorter ones at the bottom.

Step 15 16

Attach the arm rests

The upper wooden plank of the side rest is being secured with a drill.
You now need to attach another plank to the top of the side

You need: Cordless Drill, 3.5 mm wood drill bit, Screw bits, g-clamps, 2x 705 mm wooden planks, 2x 650 mm wooden planks, screws 4x45

In the penultimate step, position the planks for the arm rests on both sides of the bench.
You should also attach another plank to the front of the side rest to improve stability and appearance.

Well done! Your bench is finished and ready for its first test sit.

Step 16 16

Add some colour

The finished wooden bench is being painted with a paint spray system.
A paint spray system makes applying paint significantly faster.

You need: Paint spray system, Finished bench, Paint, Optional: brush

Needless to say, your bench will look even snazzier with a splash of colour. Depending on how creative you’re feeling, you can really go to town here. You can use a paint spray system to cover large surfaces with a unique colour. If you want to use various different colours and add some detail, it’s best to grab a paint brush or, if you’re happy to, simply get a second paint container. This saves you from having to constantly clean out the container after using it.

Once everything is dry, all your bench needs now is somewhere nice to go in your garden.
