  • Anchorage

    High Tunnel — Standard
    Size
    30 × 100 ft
    Frame
    Standard with support posts

    Standard frame carried on interior support posts rather than stepping up to the Heavy. Same snow capability at the roof, meaningfully less steel in the arch — a cheaper route to a high-load build where the floor plan can take a post line.

    The 2025 Standard high tunnel — current frame, current cover detailing, straight off the shelf at 30 by 100.

    Frame
    Mini

    A compact mini on a small footprint — the smallest thing we build, and still the same frame logic as the big houses.

    High Tunnel — Compact
    Size
    20 × 40 ft
    Frame
    W-truss arch

    A short-span build on the same trussed arch as the 100 ft houses — one diagonal and one return a side — with the back gable split into four equal bays. Full commercial frame at a size that fits a small lot.

    Thirty by a hundred on the Standard frame — arches at 5 ft on centre, driven anchors, both gable ends framed and doored. Three thousand square feet under one cover.

Nursery & tree stock

Abbotsford

A second income, started under cover.

Location
Abbotsford, BC
Completed
June 2024
Type
High tunnel
Length
60 ft

A realtor with a roadside parcel and a plan for a side business: grow trees. Nursery stock is patient work — the return is years out, and most of the risk sits in the first couple of seasons, while everything is still small enough for a cold snap or a windstorm to wipe out.

The tunnel takes that risk off the table. Stock gets a controlled start and a longer working season at both ends before it ever goes out to open ground. Sited along the road, where it doubles as its own advertising.

Commercial grow

Surrey

Room to grow, and room to drive into.

Location
Surrey, BC
Completed
March 2024
Type
High tunnel
Length
100 ft

This grower had simply run out of room. Production had outgrown what they were working in, and the brief was blunt — build bigger, and build it so machinery can get inside without a fight. The result is a wide-span high tunnel with a full-height opening at the end: the skid steer drives straight in, turns, and drives back out.

The sidewalls roll up, so summer heat vents on its own without a bank of fans running all day, and the gothic peak sheds rain and snow instead of letting it pool overhead.

Season extension

Maple Ridge

Built for the snow, not just the season.

Location
Maple Ridge, BC
Completed
December 2023
Type
High tunnel
Length
50 ft

A fifty foot Standard high tunnel in Maple Ridge, where the snow load is a step up from the valley floor. That is the argument for the trussed arch rather than a bent hoop: the bottom cord and web carry the roof, instead of the arch trying to do it alone.

Built on driven ground anchors, no concrete. Both gable ends framed and clad, doors at each end, and the sidewalls left ready for roll-up if the grower wants it later.

Sun & Steel high tunnel frame under construction in Maple Ridge, BC — galvanized arches raised on posts above grade for extra interior height, on a fresh gravel pad

Commercial nursery

Maple Ridge

It had to be tall enough to drive into.

Location

Completed
September 2023
Type
High tunnel
Length
80 ft

A Maple Ridge nursery needed a tunnel they could actually drive into — not just walk through. So the frame was set up on posts, lifting the whole structure above grade to buy back the headroom a machine needs right out to the eaves.

That extra height lets tractors and loaders work the full width inside, not only down the centre. Shot here mid-build on a fresh gravel pad, the raised arches carry the same Fraser Valley season gains once the poly goes on.

Standard high tunnel frame, 50 ft, built in Langley, BC in 2024

Market garden

Half the length, all of the frame.

High tunnel
Length
50 ft

Fifty feet is where a lot of growers start. It is the full commercial high tunnel frame — same arch, same truss, same cover detailing as the longer houses — just fewer bays of it. Nothing about the build is scaled down except the length.

That matters on a Langley lot, where the constraint is usually the footprint rather than the ambition. The house can be extended later on the same foundation line: add anchors, add arches, run the purlins on.

Home food growing

Abbotsford

The garden did not wait for the house to finish.

Type
High tunnel
Length
150 ft

A family partway through building their home, who decided the growing space should not have to wait for the last inspection. The goal was straightforward: feed themselves off their own land. The tunnel went up over freshly tilled ground with the tractor still working inside it.

Both ends open wide for airflow and access, the beds run the full length, and the Fraser Valley season gains useful weeks at each end of the year. Finished in November — which is exactly when you want to be ready for spring.

Winter build

Fraser Valley

Built through the winter, ready for spring.

Location
British Columbia
Completed
February 2023
Type
High tunnel
Length
100 ft

The full hundred-foot Standard: twenty-one trussed arches at five feet on centre, eight-foot sidewalls, sixteen feet to the peak. It is the frame the rest of the range is measured against.

Put up over the winter, between November and February, which is the part worth knowing: driven anchors mean no footing to pour and no waiting on concrete to cure, so the ground being cold is not a reason to stop.

Storage & overwintering

Richmond

Covered storage that never sees a heating bill.

Location
Richmond, BC
Completed
October 2022
Type
High tunnel
Length
50 ft

Not every build is about growing. This one is covered storage for a small business that had priced out a conventional heated building and did not like the number. A poly structure on a gravel pad came in well under it, and the savings keep going after handover: the greenhouse does not need to be heated to do its job, and daylight through the cover means the lights stay off through the working day.

Through summer they open the sides for airflow and run a shade tarp over the top, so the space stays workable instead of turning into an oven. Stock stays dry year round, and the whole footprint went up in days rather than months.

Hoop tunnel frame, 100 ft, built in Chilliwack, BC in September 2022

Field production

Chilliwack

One clear curve, end to end.

Location
Chilliwack, BC
Completed
September 2022
Type
Hoop tunnel
Length
100 ft

A hundred feet of hoop tunnel on the Chilliwack flats. The arch is one continuous curve rather than a shouldered profile, which is the cheapest way to roof a span this wide and sheds rain without asking anything of the grower.

Ground-driven anchors, no concrete, and both ends framed for full-width access. On open ground like this the end walls take the weather, so they are braced harder than the run.

Sun & Steel hoop house in South Surrey, BC with a tractor and stacked hay bales at the open end

Mixed farm use

South Surrey

Growing space in spring, dry storage by November.

Location
South Surrey, BC
Completed
June 2022
Type
Hoop house
Length
100 ft

Another farm that needed more covered ground, but a different shape suited it. This one sits on mown lawn a short walk from the house, so the round hoop profile made the better neighbour — lower and softer than a peaked tunnel, and it settles into the treeline instead of standing over it.

Both ends open, which turned out to be the part the owner uses most. The tractor pulls straight through, hay stacks at the far end, and what is a growing space through spring becomes dry equipment and feed cover once the weather turns.
