A few months back I featured an article on making your own designer patio furniture. I did mention that this was my dream patio suite and that I would be making my own patio furniture when time allowed and I have now completed the sofa part of the suite.

I had to make some modifications to the original design, as the timber merchants didn't have stock of some of the boards needed and, after waiting two months I thought it would be better to modify and use what stock they had rather than wait any longer.

The sofa is made using meranti boards. I want the furniture to last a long time, so pine was out of the question. Meranti is much stronger than pine and comes in cream and pinkish hues, which will look nice after the clear varnish is applied.

Step 1: You Will Need:

The foam for the cushions and backrest is on order an I plan to upholster these in a dark blue bull denim.
Still also need to apply exterior varnish in a clear to finish off and I will show the finished sofa once everything has been added.

YOU WILL NEED:

15 of 20 x 144 x 2400mm meranti Cut into: 7 of 600mm lenghts / 2 of 640mm lengths / 4 of 300mm lengths
5 of 20 x 94 x 2400mm meranti Cut into: 5 of 536mm lengths / 6 of 640mm lengths
1 of 32 x 69 x 1800mm PAR pine or meranti
Cut to: 6 of 188mm lengths 1 of 69 x 69 x 1800mm PAR pine or mernati
Cut to: 4 of 180mm lengths 4 x 30mm cut screws
4 x 50mm cut screws
Plascon Sunproof exterior varnish
Paintbrushes
TOOLS:
Drill / Driver plus assorted bits
Countersink bit
Mitre saw, jigsaw or circula saw
Orbital or Random Orbit Sander plus 60-, 120- and 240-grit sanding pads
OPTIONAL: Pockethole jig and accessories

Step 2: Make the Back Frame

1. Start by assembling the back frame. I want a long outdoor sofa for the patio, so decided to work with the standard 2400mm length, which drastically reduced the amount of cutting that needed to be done. Cut the section as shown in the cutting list and diagram above.

2. To join the frame together I used my pockethole jig. This isn't absolutely necessary, in fact, most of the other screws are visible, so if you don't have a pockethole jig simply do butt joints.

3. Use a corner or carpenter's square as you assemble the sections. I was so sure that meranti would be perfectly straight, but it isn't and I had a couple of slightly warped boards to work with and tried to use these where it would be as noticeable.

4. Once the frame is complete you can start adding the lengths to cover the front of the frame. This is where getting your corners 100% accurate is important. If you don't have square corners the planks on the front will be uneven at the edges. So, check twice before you fasten everything together.

Step 3: Assemble the Base

5. Now it's time to make the base. Make sure to leave all the best planks for the top and front of the base, as these will be most visible. Cut the sides and supports as per the cutting list and diagram below.

6. Use 32 x 69mm PAR pine or meranti blocks to join the double layers of panels together for the front, back and sides. In the original design this was a solid panel, but due to lack of stock I had to make a modification.

7. The blocks are attached at both ends of the front panel, as well as a block just off centre, and you will find out why it is mounted off centre below. Remember to leave a 20mm gap at the end for mounting the side panels.

8. For the supports underneath I only used a single strip of meranti. This cut down on the cost and really is strong enough. But you can add a double level support if you need extra support. Add an extra length of 144mm meranti for this.

9. The supports are secured through the front, back and seat.

Step 4: Important Note:

After completing the base and frame I wasn't happy with the height of the back and width of the front, so I made a slight modification to rectify this. On the original design the frame was mounted onto the base. I moved the frame off the base and secured it to the back of the base.

The new design allows for wider seating area and lower back.

10. To compensate for the design modification some 69 x 69mm blocks were cut to 180mm length. Two blockes were glued together and these were then attached to the base (from inside and above). Works like a dream!

Step 5: Assemble and Attach Armrests

Now all that's left is to make the arm rests. Again, use the cutting list and diagram below to assemble.

GOOD TO KNOW
Corner clamps come in handy if you are working on your own.


11. The tops are screwed onto the front and back supports.

12. The top and bottom slats are fastened first and then spacing adjusted for the centre slat.

Finishing

I sanded areas to compensate for bad cutting(!) with 60-grit sandpaper and then moved up to 120-, before finally sanding everything with 240-grit (fine) sandpaper using my trust Bosch Random Orbit Sander.

Clear exterior varnish still need to be applied to all the parts, as well as underneath for maximum protection.

Have ordered foam and will be adding high density foam cushions and a medium density foam backrest, all of which I plan to upholster in bull denim.

It honestly was an easy project. If you measure twice and cut once you are assured of a perfect design and can save yourself a fortune on buying patio furniture. Once I finish the two armchairs I will post these - and the entire finish project - onto www.Home-Dzine.co.za

<p>Hey!</p><p>So I Googled this type of thing and came across a whole bunch of designs I could copy - Then I moved on to my trusted favorite - Instructables.com!! Only to find all the images I saved from Google were from you - DeZine! </p><p>Thanks! Epic build - We all know as South Africans how expensive basics can be, and if you have a hammer and a good eye, you can save your selfs thousands!</p><p>I am going to attempt this (or the more rustic version - I don't want such straight edges for my style) in the next few weeks and will defs post an Instructable for my version!</p><p>Thank you! Will push credit you way!</p><p>PS - Where you looking to get the foam?</p>

<p>What is PAR pine?</p>
PAR = planed all round
<p>I have ordered foam for the cushions and backrest so that I can make my own to fit. But yes, if you are buying cushions they need to allow for the backrest and not be too high - mine are 150mm.</p>
I made something very similar before. Make sure to account for the size of the cushions or seat padding. I bought normal patio cushions for it (about 6 in thick) and they took a lot of the backrest space. Looked goofy.
<p>So simple and elegant. My backyard is in great need of some of this goodness. I better get busy!</p>
<p>As usual your projects are simple and wonderfully tasteful :-)</p>
<p>Looks very nicely done. Thanks for sharing this. </p>
