36 Greenhouse Design Ideas That Will Inspire You

If you're a gardener, then greenhouses are a great way to extend the growing season all year so you can enjoy orchids or fruit trees or even vegetables any time of year. But greenhouses are more than just a place to grow. Whether attached to the house or designed as a separate building, greenhouses can be contemplative spaces that allow you to relish the great outdoors even in the dead of winter. Their glass windows offer an often 360-degree view of the outdoors and allow you to stay warm and toasty even when there is snow on the ground.

This sweet steel-and-glass greenhouse offers year-round gardening opportunities for residents of the Maryland manor estate adjoining it.

Atlanta couple Cary Smith and Libby Hockenberry, owners of the Victorian Atlanta, have built several small greenhouses in their backyard to allow them to experiment with new kinds of plants to sell in their plant store; this way they’re experts on everything before they try and sell them to anyone else. In this greenhouse, they leveled the ground, covered it with Indiana creek gravel and built a nurturing environment for desert plants that wouldn’t otherwise do so well in the Atlanta humidity. Tour Cary and Libby's plant-filled home in the link below.

These homeowners love all things Disney, especially Disney World's Epcot, which is home to one of the biggest flower and garden shows in the world. So, they decided to pay homage to their favorite theme park’s landmark in their backyard by installing a 22' x 11' geodesic-domed greenhouse complete with a hydroponic growing system.

A cold frame is typically a wood box with a glass or plastic lid that uses passive solar to protect plants from cold weather. It is often placed below the ground’s frost line, which also helps insulate the plants. A greenhouse can be a structure of almost any size, and although some may use passive heat sources, they often utilize electricity or gas to heat and cool the space. A cold frame is great for hardening off seedlings that you’ve grown indoors and for growing cool-weather crops in the winter. But you won’t be able to grow tropical or warm-weather plants in a cold frame in the winter months. With a climate-controlled greenhouse, you can grow a variety of plants throughout the cold weather, plus do all that a cold frame can do, too.

The accessibility and portability of this raised-bed greenhouse is bound to lead to a lot of plant productivity. The 46" x 46" raised garden greenhouse is perfect for growing in small spaces. It sits 28 inches off the ground to make gardening accessible to everyone. The lids can lock open for full access to do your planting and harvesting or for ventilation. The polycarbonate panels also help protect plants from pests and the cold. Plus, the lightweight materials make it easy to disassemble and move the greenhouse. The structure includes two planting areas, internal water drainage and plant hangers for trellising. Plus, it has built-in storage space for gardening tools and accessories.

We love this charming greenhouse attached to the back of the home's garage. It was built inexpensively from salvaged windows, a dumpster-dive door, recycled lumber, an old clawfoot tub and other repurposed building supplies. Because it is attached to the home, electricity and water were easily run to the greenhouse, making it convenient to water the plants and control the climate.

Packed with functional growing space and clever ideas for reusing vintage finds, photographer and farmer Becca Skinner's Montana greenhouse is a dream come true, especially in winter. The 14’ x 20’ kit is from Cedar Built Greenhouses. Becca chose to go with a custom, wider build (their typical greenhouse is 12 feet) because she wanted enough space to fit a dinner table inside for hosting events or dinner parties. There are eight automatic vents on the roof to let hot air out in the summer and two fans near the floor vents to help move air through when it starts to warm up.

A custom-built conservatory or hothouse can be very expensive — save money and build your own. DIY greenhouse plans with cut lists and step-by-step instructions are readily available online starting at around $10. They'll make the process a lot easier and stress-free. This combination greenhouse and shed was built from a plan that was purchased from an Etsy shop.

Greenhouse floors need to have excellent drainage. Floors can be made of concrete, stone slabs, brick, sand or even dirt. Gravel floors provide excellent drainage and can be used in conjunction with a weed barrier to keep weeds from growing up through the rocks.

To conserve water and save money, these greenhouse owners installed rain barrels underneath each of the gutters to collect valuable runoff to water the plants inside and out. A trio of cold frames on the side of the greenhouse extends the growing season and the growing space.

Ridge cresting, jalousie windows and the semi-circle detail in the eave give this aluminum greenhouse a quaint English-country look. The louvered windows and ceiling vents provide plenty of temperature control and airflow on warm days.

Fenced all the way around, this spacious backyard was designed to encourage the entire family — including the kids — to take an interest in gardening.

See the inside of this greenhouse in the next slide.

In the previous slide, we featured the outside of this luxurious greenhouse. The inside is not just a place to grow plants, it's also the homeowner's favorite getaway — in their own backyard. A large woodburning stove and radiant floor heat mean they can enjoy the space year-round.

Using your home as the fourth wall of your greenhouse is a great way to save money and help provide radiant heat to your plants. Here, the homeowners used the existing patio and just added a concrete footer for the greenhouse to sit upon. Another plus of a home-attached greenhouse is easy access to electricity and water. When buying a greenhouse, look for windows that are tempered safety glass and a rustproof frame like this one.

A greenhouse can function as a stylish adjoining room to your home where you can enjoy an indoor garden year-round. The all-mahogany frame, ridge cresting and stone walls of this design by Conservatory Craftsmen also includes in-floor heating.

This natural wood greenhouse offers gardeners the beauty, warmth and natural ambiance of a solid cedar conservatory. The 8' x 16' structure features a high peak roof that allows summer heat to rise and easily sheds snow in the winter. Red cedar is a great choice for greenhouses because it is insect resistant and won't rot like other woods.

Greenhouses are no longer just for growing plants and are now being enjoyed by homeowners as garden retreats, artist studios, exterior living rooms and architectural showpieces. This backyard getaway has all the attributes of a nature conservatory — we especially love the old-school streetlight standing in the center — but it can serve many other purposes with its all-glass structure and auto-open roof vents.

During the summer months, consider hanging white curtains along the hottest wall in your greenhouse. The white fabric not only creates shade, but it won’t absorb the sun’s heat and re-emit back into the greenhouse.

Sliding doors that open wide make it easy to move large planters and tables in and out of the greenhouse. Speaking of doors, when choosing a greenhouse for your yard, it's important to have secure door latches to help lock in humidity and moisture, two elements necessary for plants to thrive inside.

This off-the-grid home made partially from an old silo has an attached greenhouse that serves as a dining area as well as a place to house plants.

Inside your greenhouse, stick with shelves and vessels that are low maintenance and easy to keep clean and tidy with a garden hose and heavy-duty nozzle. A variety of plant stands will allow you to move things around as the plants grow. Tables and benches made from wood slats allow water to freely drain from containers.
