This greenhouse embraces both indoor and outdoor living, reflecting the lifestyle of its owners. An intimate outdoor patio constructed from recycled composite railroad ties features a custom-made fire pit. The patio sinks comfortably into the space created by small gabion walls, and a terraced succulent garden leads up to the airy and elegant greenhouse, which, thanks to radiant heating in the floor, offers the owners the perfect place to enjoy relaxation and entertainment year-round. The dimensions are 60′ by 20′, or 1200 square feet. (via Groundswell Design Group)

8. Cold Frame Greenhouse.

Extend the growing season with a cold-frame greenhouse. More of a protective box than a full greenhouse, it shields seeds and young plants from harsh weather while allowing sunlight to nourish them. This lean-to is ideal for all high-climbing vegetables and fruits, such as tomatoes, cucumbers, beans, wine, and peaches, which prefer a high, heat-storing wall to thrive. But classic lean-to roofs are also suitable as a transition from the house to the garden. The interior is used as an additional living space “summer room.” (via Alitex Deutschland)

9. Modern Minimalist Greenhouse.

A rural retreat in the Barossa Valley of South Australia features this greenhouse of polycarbonate/aluminum for maximum sunlight exposure. The greenhouse manufacturer is Aussie Greenhouses. The greenhouse dimensions are 26’x10′. The flooring is pea gravel. The straw bales make a great place in which to grow many veggies. The bales around the greenhouse help to stabilize against the wind. Tomatoes, in particular, love the barley straw bales. Here is a good site for growing tomatoes in straw bales.

10. Tropical Tatton Greenhouse.

11. The Garden House.

This backyard greenhouse shed, measuring 10×12 feet, is built from rot-resistant cypress on sturdy steel posts. Inside, a brick-paved floor provides a cozy, rustic touch. It offers enough room for potting, plant storage, and a small seating area. Though tucked into a semi-shaded garden nook, its insulated, reinforced panels efficiently absorb sunlight, creating an ideal environment for nurturing plants. (via Better Homes & Gardens)

12. DIY Recycled Window Greenhouse.

This greenhouse was constructed using salvaged windows and doors. Using reclaimed materials is a budget-friendly option if you wish to DIY your own greenhouse. You can find these materials at local salvage yards, antique stores, estate sales, Habitat for Humanity ReStores, eBay, or Facebook Marketplace. Be sure the frames are sturdy and not rotted. Selected single or double-pane windows. The latter will work better for insulation. Once you have collected enough windows, get creative! You will have a structure that fits your outdoor space, perfect for seedlings, growing vegetables, or even a place to store your summer potted plants. (via Twist My Armoire)
