How to build a timber garden arch for climbing roses each side?

[aussiejack1]

To replace destroyed arch.

Width to span 1m path, plus a bit each side (total 1.4m?).

Height 2.4m if flat top, or 2.4m to peak if arched. Old arch had to 2 posts about  1.2H with routed channel to hold lattice panels.

Lattice panels, starting 350m from bottom, then 700m high. 

Then moving upwards, 2 more cross panels spaced about 250mm apart .

Will be guided as to standard measurements to various timbers and lattice.

Hello @aussiejack1 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about building a timber garden arch.

Are you thinking about recreating the same arch you formerly had? If you are, would it be possible for you to post a photo of the old arch. You also mentioned a possible choice between a flat top and an arched build. The flat top would definitely be easier to build, the store does not carry pre-bent timber for archways.

Please give me some time to draw up a sample archway and I'll post it here as soon as I'm finished. Please note that the store also carries rose arch kits such as the Brunnings 2175 x 1150 x 440mm Classic Timber Arch.

If you have any other questions we can help with, please let us know.

Hello Eric,

In reply to your queries:

• Yes, I wish to re-create the old arch as accurately as possible.
• Here is a photo of it. Not much is showing of the arch part, however, I will take your advice and go for a flat top.
• It follows I prefer not to have the Bunnings “classic timber arch”.

Looking forward to your instructions for next step.

Hello @aussiejack1 

Thanks for sharing that photo of your garden arch. For the materials, I suggest using either the 70 x 45mm 3.9m MGP10 H4 Treated Outdoor Structural Radiata Pine or the 90 x 45mm 4.8m MGP10 H4 Treated Outdoor Structural Radiata Pine. Both these timber products are ok to be used indirect contact with the ground. For the lattice, I suggest either the Lattice Makers 1800 x 900mm Treated Pine Lattice or the Lattice Makers 1800 x 600mm Unpainted Expandable Trellis. 

I've placed a sample image along with general measurements to give you an idea of how it can be assembled. The second image is an example of placing a gazebo style top over the garden top.

If you need further assistance, please let us know.

Thanks Eric,

A question: In my old arch the upright posts were routed so that the lattice and cross pieces slid into the groove.

Is it possible to purchase routed timber, or does Bunnings do that type of thing?

Thanks again Eric,

I think I will go with the arch with the flat top and cross beams. Can you tell me the recommended overhang of the cross beams please.

Hello @aussiejack1 

In the design I drew for you, I conservatively placed an 80mm overhang past the frame on either side. This is to make sure that it does not become too visually overwhelming and heavy.

If you need further assistance, please let us know.
