GREENHOUSES FOR EVERY LIFESTYLE
At Greenhouses by NWGP, we believe a greenhouse can be so much more than just a space for plants. Our custom designs offer a unique way to expand your living space—without the cost or complexity of a traditional home addition.
Over the years, our clients have transformed their NWGP greenhouses into all kinds of personal retreats and functional spaces: conservatories, sheds, pergolas, covered patios, floating decks, raised garden beds, carports, hot tub enclosures, art studios, cozy sitting rooms, cigar lounges, book nooks—and the list keeps growing.
With a custom greenhouse from NWGP, you're not just adding a structure—you're creating a space that reflects your lifestyle.
VENTILATION SYSTEMS INCLUDED WITH EVERY GREENHOUSE!
With each and every one of our greenhouses, we offer a professional auto-rise ventilation system. With our ventilation systems, the entire peak of your greenhouse raises all on it's own— eliminating the excess heat from the greenhouse. The system will drop back down once the greenhouse has cooled down.

Why Ventilation Matters
Bayliss Automatic Vent Openers
Our Bayliss systems feature a beeswax cylinder that expands and contracts with temperature changes, automatically opening or closing your vents—no electricity required. It’s a set-it-and-forget-it way to maintain a balanced greenhouse climate, even when you're away.
Standard Roof Design: The entire ridgeline of our Standard roof option is outfitted with vents operated by the Bayliss system, allowing hot air to escape through the highest point of the structure.
Modern Slant Design: Our Modern Slant models feature upper venting windows at the peak of the slope, positioned to release stagnant, rising air efficiently.
Operable Windows
Strategically placed operable windows can be manually opened or closed to promote airflow and help release built-up heat. They work especially well when paired with Dutch doors for cross-ventilation.
Dutch Doors
All NWGP greenhouses come with a Dutch door design. Opening the top half allows fresh air to flow through the lower part of the greenhouse while keeping pests and pets out. Combined with windows, it creates excellent cross-ventilation for consistent airflow.
Additional Ventilation for Larger Greenhouses
For larger greenhouses, we recommend incorporating additional operable windows or roof vents based on the structure’s size. This ensures that air circulates evenly throughout the space, helping to eliminate hot spots and maintain a stable environment.
