New tunnel dome design

This design is the other way, I don't normally build tunnels in this format but after seeing a picture of the network rail station at canary wharf, I thought that it could be a useful design.

I liked the ends that curve out towards the top and a triangulated tunnel will have no problem withstanding any snow load.

If you like this design or have any questions/comments about it let me know in the comments section below.

Thanks for watching.

I have watched this video several times. I am all in! 🙏🏽 Thanks for sharing your design. I will be in contact...

I really like the look of this.. the one straight wall is perfect for where I want to place it.
Looks way better than a poly tunnel.

Nice design! It has a pleasing shape and looks very sturdy. The flat wall has many practical uses. Maybe it could be against a building. Or the flat side could contain a thermal mass, such as the tire wall that Robert Coffin suggested or barrels full of water, etc. I would probably want to build one.

That's a great idea and design. I am so interested that I would consider building this after my dome house is completed later this year. Thanks.

Why I've not come across your site before last night is difficult to say. I'm glad I have though.
This is potentially more practical for smaller plots than a dome, and I think it's great. I've been thinking of something similar above a sunken garden with a trombe wall at the rear to temper the heat.

Would love to have the plans. I also think it would be really cool to connect a tunnel to a done on one or both ends

Quite interesting concept as a winter garden Paul.

It certainly has an appeal. I could see one end wall flush with the top and one recessed: even with the bottom; leaving an awning on one end. It is elegant.

Hi Paul, I love your very elegant design. I have been looking at domes, but this shape looks far more practical, and extendable as needs develop. I’d be very grateful to have the plans when they are ready. Thanks for sharing!

Backwall, but make it with holes with netting to the backside, and then you fill up leaf and grass compost high against the wall. Free heating into your greenhouse for the winter! 👍 😊 Nice design. Probably very sturdy too.

[abrahkadabra]

Beautiful building! Love the simplicity. 👍

[orionbound]

This looks great. Looking forward to plans!

[gonpin]

I love your work... and this tunnel is exactly what I was looking for... Please go ahead with this original plan...

[leverman]

Oh yes, I'd like to see the plans and the video of the build if you construct it. I did a rather plain gambrel roof greenhouse over my cellar and I'd consider remaking the front to this style or an overlap.

[graybeard]

I am definitely interested in plans for this. I will buying some of your other plans as well.

[christopherneelyakagoattmo]

Poly tunnels are cheap; and they look it! Definitely interested in a plan. Watched the vid again.

[karlkraut]

this is brilliant, just waiting for plans to build this

I plan to design a center dome that can have up to six 'tunnels' connected to it. I love this design with the part that extends out. Looks very nice. Goal is to have a center common room and each tunnel its own function, like kitchen, bedroom, office etc. Did you every combine a structure like this with a dome? I first planned to do that with containers (in place of the tunnels) and a dome on top in the middle, but this seems more cost effective and also much nicer to look at.

In the version with the high back wall, will there be a lot of sideways force on the top of of the wall? It looks like it would be forced out if the dome sags. If one had a sloping site of the correct orientation, then the tunnel could be built into the slope to take advantage of the thermal mass of the earth. Vertical alcoves behind the wall with access both from the top, and inside the greenhouse, could be filled with compost to provide extra heat. I have watched a lot of your videos over the weekend. Very informative, so thanks for sharing your experience of design and construction.

Looks much better than a Polytunnel. At a charity by me they have several polytunnels but youths got on the ground and slashed them. They look even worse with the gashes taped up. Using triangles not only looks better and more sturdy but also means the individual triangles could be recovered if damaged.

Not so keen on the riser wall. Would look better if sunken into the ground slightly. A bit like they do in South America. Just remember to use a dense material for the submerged walls to trap the heat, like stone or brick.

I think something half way between the two designs might look nice. i.e. use the second design but on the wall side bring the roof down one extra row of triangles.
