Building exceptional functional artwork, by hand, one project at a time.

We can build and ship to you, or if you are in the Portland Metro, or Willamette Valley area of Oregon we can build in home projects.

6. Windows, French doors, vents, and such. These windows are what I based the whole design of the greenhouse. They’re just under 6ft x 6ft, double paned picture frame windows from Marvin (brand new). I scored 16 of them from an auction ($2000 for all of them).
After house-wrapping the walls, I was able to install all these windows with help from Braddah Chris. The French doors I found on Facebook Marketplace, and they were installed with help from Braddah Scott. The exhaust vent fans are pretty cool, they both can be programmed to turn on and off at different temperatures. They’ll come in handy when we have triple digit summer days.
All the windows, doors, and vents were trimmed out using leftover redwood that I milled down.
I had 3 of the big windows left over which I’ll most likely use on a home addition in the future.

5. Twin-Wall Polycarbonate roof panel system.
I didn’t document all of the steps, but it’s quite involved. Each panel had to be prepped before installing: Cut it to length. Use air compressor to blow the tiny plastic shavings out of each fluted channel. Tape top and bottom edges with vented tape to allow moisture and condensation to exit the flutes, but keep bugs from gittnupindair. Put rigid plastic cap on top and bottom edges of roof panel to prevent critters from gittnupindair. Then there’s a 2 part locking channel that goes in between each panel and attaches to the roof rafter, etc. etc.
Quite involved.
I spaced the roof rafters 24” on center. But didn’t account for the locking channels (which added 3/4” between each subsequent panel). So by the time I reached the far end of the greenhouse, I had to add in a few roof rafters, which was pretty tedious.
The last step was to cut, bend, and attach a metal ridge cap to the peak of the roof in order to waterproof and bugproof the roof ridge. I also added an open celled foam barrier under the metal ridge cap to allow for Hot Air to escape the during the summer, but still prevent bugs and sideways rain from gittnupindair.

4. Framing - I used 2x6 redwood to frame this greenhouse, with 2x8 cedar for the window and door headers. Ridge board was 2x10 cedar. I got all the lumber at the heavy machinery auction in Woodburn, OR. I did use pressure treated lumber for the bottom plate, and pressure treated lumber for the double top plates just because they can bear a heavier load than redwood. All the nails and hardware are electro galvanized, or stainless steel.
As mentioned earlier, this greenhouse is in the flood zone of the property and I wanted to make sure that all the materials I use would not be affected if they were ever inundated with flood water. About halfway through the framing, I started wearing a dust mask, because cedar and redwood really do irritate your respiratory system, even to the point where you start to exhibit head cold, and flu like symptoms.

3. Flooring - this flooring was designed to let water drain out without any repercussions. Installation was identical to how you would do a patio paver system, except a used regular sand instead of polymeric locking sand.
I cleared out all of the roots, trash, and debris and leveled it as best as I could. Then I dumped a couple truckloads of 3/4 minus gravel and compacted it. After which I spread base sand and screeded it using galvanized, gas pipes, and the straightest 2x4 I could find.
The red concrete pavers help collect solar energy in the winter time, and they allow water to drain out easily.

2. Foundation: This footing was just under 5 yards of concrete. I should have took more time to prep for concrete, and took more time to finish it before it cured…but it was hot and I was tired. I hammered some rebar pins into the gravel and used a laser level to get them perfectly level at all 4 corners, and at the midpoints of each trench.
When the concrete being poured was at the top of each pin I would stop and move the chute and fill in the subsequent sections. Had I spent a little more time screeding and troweling the concrete flat I would saved myself a few days of work thereafter. But I got sloppy.
The end result was a difference of 1.25 inches between the lowest and highest points in the cured concrete. That meant all the CMU blocks needed to be leveled at the highest point of the poured concrete foundation.
In other words I had to build a base of wet mortar under each low block to lift it up to the highest point so that all of the greenhouse walls would be flat and level (no roller coaster). It sucked, and it took me a couple extra days.

Part 1. Excavation and foundation prep:
The greenhouse sits in the floodplain of the Pudding River so I over-engineered the foundation to compensate for the frequent flooding that will likely occur each year.
After clearing out all the roots, buried trash, and debris, I back filled the perimeter with about 12” of 3/4 minus crushed rock and compacted it with a hand tamper. This would be the bedding for the concrete foundation to sit on.
The old lady I bought this property from said there was never anything down there, just some blueberry bushes that her late husband planted heehee (Lies 🤭). I found remnants of an old burnt down house; tiles, toilets, silverware, roofing, siding, electric wires, etc. all buried where I was digging.
The elevation of the greenhouse in relation to the river is about 10ft below the main house. It’s very fertile ground but floods at least once per year.

I’ve been working on Djitu’s greenhouse since summer. Dimensions are 16ft x 25ft, any larger and I would’ve had to pull a permit. Framed with redwood and cedar, big double paned picture-frame windows, French doors, concrete paver floor, and a twin-walled polycarbonate roofing system. I got all these materials at auction (except the roof), or milled them at home. The foundation is a 12” poured concrete footer with 1 row of CMU blocks on top. The pavers allow for water drainage, and the untreated unfinished redwood and cedar are ideal for a perpetually damp environment both inside and out. This was truly a labor of love, as it was made for the most beautiful, smartest, and kindest woman I know. I’ll post the whole building process in chronological order, but here’s the building ready go.

Finally put this table to work. It’s been finished for weeks, but I couldn’t find the right chairs.
This table is made from all the scraps and offcuts from dozens of different conference tables, dining tables, art pieces, coffee tables, book shelves, sliding doors, jewelry boxes, and everything else I’ve made since 2019.

Resurfacing after a long hiatus with a new project dubbed “The Leftovers”. I have a habit of saving cutoffs and scraps from previous projects and proclaiming that I will use them for something in the future! Today is the day. This 3’x5’ dining table will be made from multiple different slivers, scraps, and leftovers from dozens of past projects.

We have Elm, Black Walnut, English Walnut, Claro Walnut, Big Leaf Maple, Silver Maple, Oregon Ash, and Pine for the base layer. I’m sure I forgot a couple more... I’m committed to using every dust-covered scrap in my shop to Frankenstein this work of art together.

This was a personal project. I started months ago, but had to put it aside in order to fill a few large orders. Now it’s complete, and off to live in a friend’s home in Portland.
