Looks like they are metal, right? You go to an iron works/metal works/artist, and in all likelihood they would be thousands of dollars. If you could settle for straight lines, you could get a handyman/carpenter to do it for much less in pressurized lumber or cedar.

I agree; those were probably made to spec for a landscape designer. You could get a similar effect by setting up a series of arches, spaced equidistant and run a stringer along the top to connect them, as if one long arbor?

I think I saw someone on eBay who made regular arbors in custom widths, maybe check there! HTH! (It’s a beautiful effect!). :-)

I had bookmarked this site a while back; they had something similar under “arches.”

Jin, you might be able to do something similar with rebar. You can get the lenghths cut to fit, but you would need to weld them. I plan to use rebar to make an arched span across the two middle posts on my someday arbor. Cori Ann used it to make an umbrella and also a free-form tree trellis. Of course, the rebar isn't as gorgeous, but who cares once your beautiful roses cover them!? : )

We’re building ours (3) out of fence posts & rebar...not pretty right now, but most of my roses are evergreen, so they will cover it up. We’re cladding one in stained wood, just because it’s very prominent in the garden, and it’s just for appearances. You can get 10’ 2” pipe for $25 each—sink it 2’ and still have 8’ height. :-)

At one time I planned to do this using simple individual arbors and connecting them with cattle fencing (hog wire), similar to what Perma 'n Posies suggested. In your climate the wire would be covered in no time.

If you live near a farm supply or feed store, they sell cattle fencing in panels in various gauges.

A landscape company could direct you to someone who does this kind of work. It would be beautiful to see something like this covered in roses! I hope you can do it and post lots and lots of photos to inspire us.

No worries, Jin. When something goes wrong, I assume it's another one of Houzz's goof ups.

My husband is a reinforcing structural engineer. He has access to rebar any time, but we only have one very large piece, flattened on one end and so heavy that I can't lift it. He uses it to dislodge and leverage big rocks out of holes for roses.

Look on Wayfair or Google "metal pergolas".

The cheapest way to do it is to line up 5 treated wood posts on each side, then use a thick rope link all the posts together on top. In a few years climbers/rambles would cover all the posts and ropes. Each post ( 4"x 4"x 10') costs $9.00 each, 50' rope (2") costs $150 from HD. You have to find a guy to dig 10 holes for you though.

They look like something that Agriframes would do. I have used some of their garden structures in the past and been very pleased with them. They coat the metal work, so that it doesn't get too hot or too cold.

Google lists an Agriframes USA, but my link is to the UK site as it seems to be easier to use.

Jin, I have had this company bookmarked for a while. It looks like they use good quality iron and shipping is free which helps with the cost. The Patterson tunnel arch is similar to what you posted. https://www.arusticgarden.com/arandar.html

So gorgeous! But maybe too formal for my cottage gardens. I have had to build most of my structures. This is the biggest one. I had cattle panels laid flat on the top at first, but I needed them for my lamb's pens

so they were moved to use there. I have been trying for years to get a hardscape path put in. Hopefully this coming spring. I originally was going to connect cattle panel hoops together after a similar design I saw at the Minnesota Arboretum. I haven't figured how tight the panels will come together. I'm going to find out later this week as I have two I want to make for my new garden/patio I put in this year.

Here’s what we’ve done so far, out of fence posts, pipe fittings & rebar. Next step is the wood cladding. I’m thinking this will come in around $225-230.

(Please pardon the mess; this area is still very much under construction.) :-)

Wow! I'm saving this post! Amazeballs! Who is that has the "tusk" arbor?

We have nothing lavish as your beautiful structure, but we did have a number of tuteurs made mimicking ones we saw in Les L'hay Rose. We took photographs to a wrought-iron place down near the Mexican border. When they came back they were double size and glorious. We're pretty sure they were outsourced and crafted in Tijuana.

I think I remember reading a thread where Cori-Ann was building her own umbrella trellis? I bet she could give some good advice.
