Greenhouse Structures

Attached even-span greenhouse

The even-span is similar to a freestanding structure except that it is attached to a house at one gable end. It can accommodate 2 or 3 rows of plant benches. The cost of an even-span is more than the cost of a lean-to type, but it has greater flexibility in design and provides for more plants. Because of its size and greater amount of exposed glass area, the even-span will cost more to heat.
