The Building of a Greenhouse

Well, after months of debate on the type and style of greenhouse to use, and after much consideration with respect to price for prefab structures I have opted to build my own greenhouse from the ground up...without using plans. Here is what it looks like thus far. I decided on a 12Wx20Lx9H structure to start with...

As you can see this is the post setting stage with an 80lb bag of concrete securing each post.

These are two old 7x13 dog pens that I will be converting to cold frames once the greenhouse is finished.

  This is the Girt additions to tie it all together.

  and the trusses for the roof, the peak is 9 feet and the side walls are 5.5 feet, the whole structure is 12x20 which should provide plenty of room to start and I have plenty of room to grow the structure on the left side if needed.

The roof sheathing is being placed and regular composition roofing will be used on the north side of the structure. Notice the additional bracing on the girts.

The next stage was placing the siding, I used T1-11 and cut opening for windows and also place felt paper on the north side of the roof.

and here is the structure as it sits now, I have completed the purlins for the corrugated clear polycarbonate panels on the south facing portion of the roof, and painted them with white paint as recommended by the panel manufacturer. Now on to painting the rest of the greenhouse to match our home. Time to complete this stage - 2 weeks @ 4-5 hours per day.
