Free-Standing Greenhouses


We have been building free-standing greenhouses for over 30 years. Our common sense approach to greenhouse design has resulted in cost-effective, energy-efficient structures combined with ease of installation. If your location requires high winds or heavy snow building codes, we have the perfect structure for you.

The standard widths available for free-standing structures range from 16′-35′ clear spans with sidewall heights from 4′-10′. Our solutions to your greenhouse needs provide you with choices of round, rectangular and square tubing, and covering options of poly or polycarbonate. We have the right structure, at the right price, to help you grow your business.
