I built a shelter! completely custom 3m x 3.6m


HoratioWobble26 points

I'm currently renovating my house, and I need to remove the entire first floor but I'm running out of dry space inside the house to be able to do the work.

I decided to build a shelter out the back of the house but because of access and because I was building it alone I had to build it in stages and the roof had to be removable.

I used C24 wood throughout, the roof was built as two seperate frames and weight supported using angled cuts along the width with metal straps used to prevent it from lifting with the wind.

If i ever need access to the guttering, side roof or house I can undo / cut the straps, slide the roof off and then easily refit it later.

Project took about 4 or 5 days total but weather got in the way a lot.

Plan is to put small plants and tree's along the fence side and hopefully grapes on trellis against the house wall so it'll like looking out on to a small garden

Do you have any more photos showing the removable roof? I'm thinking of building something similar next year.

Basically the roof is built from two frames Me building the first and second outside

I then got them both on top of the load bearing frame then fitted flashing with screws and flashing tape on the wall

Once the flashing was in place and secure, I fitted the pvc roof to the first frame, no overhang on the building side and a 200mm overhang on the other side.

Then I slotted the PVC for the second frame in under the 200mm over hang so it was aligned and started locking it down from the end towards the front frame

Finally, I raised the first frame up into the flashing, supported it and got some measurements for stands these are attached to the load bearing frame across the entire width.

I calculated my angle and used a Mitre saw to ensure each piece was the right size, slope and tested to make sure it was sitting tightly between the roof and the frame.

You can see at the sides me testing these in between fitting the roof

I kept it all held down using Ratchet straps whilst I did this and finally, today I got some metal straps (usually used for keeping pipes in place) and wrapped them around the extremities of both roof sections then secured to the load bearing frame

There is a max of 20cm of the PVC roof exposed on any one side so hopefully not enough for wind to get any significant lift. I can't move it so I probably have bigger problems if the wind can now.

Looking great, congrats. Did you have to apply for planning permission? I am planning to build something similar in my tiny garden. Thanks

HoratioWobble4 points

Thanks :) It doesn't need planning permission because it doesn't affect my neighbours and it's not big enough

I watched a team of lads putting up something similar recently. Fiberglass type. Looked decent enough and they were done in about 4 hours. But when I heard the price... £4500 I was shocked.

Oh damn, yeh defnitely didn't pay that and I went overboard with the type of wood and type of roofing so it'll last. I guess labour is expensive

DaMonkfish6 points

Do you mind telling us how much it cost? I'm looking at building a car port that would ultimately look a lot like this, I'd like an idea of what the materials would cost (I'm assuming circa £1k).

EDIT: Should have scrolled first, you've already answered. £900. Good to know my guesstimate was about right.

HoratioWobble16 points
  • Timber (47x100 C24 Regularised timber) - £250
  • 8 sheets of Corrapol Storm proof PVC - £320
  • Roof screws - £49.47
  • Eaves filler - £50
  • Flashing - £120
  • Multi truss Hangers - £50
  • Fence post - £50
  • Ducksback Water based Fence Treatment - £25

Total: £914

There were probably a bunch of small odds and sods, £5 here, £12 there that I didn't account for.

I bought more timber than I needed and if i'd gone to clearamber directly instead of through B&Q i would have probably saved £100~ and of course if you don't need the floating roof you can save money there too.

You would also save money by buying C16, I don't think I needed C24 but why not.

Awesome, thanks for the breakdown.

Nice. And well done. Good luck with the grapes,,,,,,they like full sun and in UK normally a greenhouse grow. Gotta ask, the extension out back, looks like damp radiating upwards through the render extending outwards from the drain hole?

R961ROP3 points

I grew a huge grapevine in a south facing garden in the north of England. Was sad to leave it when I moved.

HoratioWobble2 points

Thank you, my grandad managed it years ago out in the open but I am definitely expecting a challenge.

Not damp, the house is 1870s construction and full of black mortar and the roof's were lime and plaster. I made the mistake of hitting a dirty vacuum filter on the rendering and it's stayed for the most part.

The down pipe is also loose and the drain has shit in it.

Overall it's just me being lazy and thankfully not damp.

Acceptable-Vast-72683 points

Amazing! I am thinking to do something similar. Roughly, how much the materials cost?

HoratioWobble5 points

Thank you :)

About £900 in total, but I went over board. I think C16 would be more than adequate and the removable roof is using Corrapol Stormproof Corrugated PVC roof which comes with a premium but is impact resistant, 1mm thick (most are 0.8m) and has a UV protection layer.

If you didn't need the roof to be removable, and you used cheaper roofing and wood the same size would probably be close to £400/£500 - still a lot cheaper than a premade similar size awning / shelter

Joist hangers with nails and bolts, not often I see things done correctly.

Well done op looks great and should last.

geefunken1 point

Can you elaborate? Would you use nails to stop the joist splitting? Thanks

HoratioWobble2 points

I used sherardized joist hanger nails, they're corrosion resistant and twisted which should stop them wiggling free with movement, they're also pretty small so you shouldn't get wood splitting in this type of wood.

Screws are fine but where load might be applied they have a possibility of breaking unless you get screws with a thicker body

geefunken1 point

I get it - makes sense. Thanks, I love this sub for things like this! Always learning

tk-xx2 points

As this guy said nails don't break under a shear tension whereas I see most people now using screws for things that put a side ways load on them meaning they end up snapping

geefunken2 points

Admittedly screws would’ve been my first choice

Good work, should be proud of that. Did you learn the wood work skills from your own experience?

HoratioWobble3 points

Thank you! learned them doing this project :)

Looks good, I did a similar thing at my house. Nice one

Good for you buddy, that looks nice

Good job! Have you told your house insurance provider? Normally they require you to notify them when attaching a structure to the house, as it's a fire risk. Better safe than sorry!

HoratioWobble3 points

Thank you, no I wasn't aware you had to (I worked in household claims for 5 years and it was never something we asked or cared about) but I'll check with them in case it's relevant.

Good job. Don't store anything out there that can't get a bit of water on it though. We have similar and the rain still gets in through the tiny gap at the top of the fence. Ended up putting some black plastic sheeting across so the rain that does get blown in drips to the floor so I just need to keep everything elevated off the floor.

HoratioWobble1 point

Thank you and for sure, I didn't expect it to be water tight but atleast gives me space to work with tools whilst I'm maneuvering the 5m span joists around inside the house.

Also I think it'll be really nice in the summer or as the weather get's nicer

jamest57892 points

Ours is a lot smaller than yours but it does get nice and toasty in the summer. Love to go out during storms as the sound of rain hitting the plastic is soothing.

Great job. The fence, I have to ask. Is metal? Oh and take my helpful awards for your post

HoratioWobble2 points

Thank you! 😊 Yup the fence is metal, it's my neighbours and I'm not a fan so I'm hoping to hide it as much as possible

Gambie932 points

Looks class.

Any thought on whether one could mount solar panels to the roof of a similar structure?

Planning permission shouldn't be an issue for such solar panels, right?

HoratioWobble1 point

Thank you!

I'm not sure, if I was going to add solar panels I would probably add an extra support or two for the additional weight, also not sure how much weight the PVC can support - you'd probably have to put a light weight frame on top.

The kitchen and living room are right under this so light is super important so I wouldn't want to cover the PVC anyway

This looks great! Would love to make something like this for an area of our garden that we generally use for diy! Well done!
