A Room For All Seasons --- Whatever your budget, a greenhouse is within reach. Here's how three homeowners made it work at very different price points.

 

“For gardeners, a greenhouse is the ultimate luxury, offering a head start on spring even when snow still coats the ground.

 

But many homeowners now want their glass-walled rooms to do more than grow plants. Today's most creative takes, which include stand-alone greenhouses and conservatories attached to the main house, double as places to read, relax or entertain, surrounded by year-round greenery.

 

That kind of double duty requires careful planning from the start, designers say, since choices about insulation, environmental controls and glazing can quickly push costs higher -- and are difficult to reverse later.

 

At three very different budgets, these light-filled spaces support thriving plants while also serving as a peaceful escape.

 

A Modest Tennessee Retreat

 

If you don't want to drop six figures for a garden sanctuary, build-your-own kits from greenhouse companies like Janssens and Alton can be had for low five figures.

 

On her Tennessee property, designer and antiques curator Lauren Sullivan opted for a 13-by-20-foot Victorian Lodge model from the U.K.'s Hartley Botanic. While Sullivan didn't disclose the price, Christiana Drewry, a gardener and landscape designer, said she's come across small Hartley Botanic greenhouses that go for about $40,000.

 

Features like temperature-regulating roof vents and roller blinds keep the space functioning year round.

 

To maintain stylistic cohesion between the main house and greenhouse, architecture firm Brooks and Falotico designed a matching foundation of Tennessee limestone.

 

Sullivan sourced and styled the interior decorative materials herself, including Spanish tile from 1stDibs, an online marketplace. She added an onyx sink from Olive Ateliers, mounted upon a rustic vintage farm table from Litt Concept House.

 

"There's something incredibly grounding about being surrounded by glass, greenery and natural light," Sullivan said. "[The light] shifts throughout the day and across seasons, keeping the space feeling alive."

 

A Six-Figure Sanctuary

 

When a fire razed their home in Ripon, Wis., Jackie and Chuck Nelson, who run a commercial painting business, reimagined the space formerly occupied by a music room and office into a Victorian Gothic-style conservatory.

 

Jackie was passionate about growing some of her favorite tropical plants from Florida, where she's from, Midwest winters be damned. "The only way to grow orchids in Wisconsin is indoors," she said. They turned to Jim Hewitt, a master gardener and owner of Minneapolis design-build firm Conservatory Craftsmen.

 

For the 14-by-23-foot climate-controlled space, Hewitt wrapped a steel substructure in Sapele mahogany to create a room that felt both warm and welcoming. Decorative muntins on the insulated windows make the panels look like they're crafted from individual pieces of glass.

 

A travertine floor provides an even transfer of heat in the room and holds up to temperature swings. In place of the former chimney, the couple opted for a mahogany-wrapped gas fireplace, which sits low, allowing for regular sightings of wild bucks and birds. "It's the place to watch the sunrise, especially on cold mornings while sitting in front of the fireplace with our pets and a delicious hot cup of coffee," said Jackie.

 

The Nelsons said the whole project cost between $350,000 and $450,000. The orchids are thriving and the space has made for a great backdrop for their daughters' wedding photos.

 

A Low-Cost Labor of Love

 

When Christiana Drewry, the gardener and landscape designer, and her husband, Kodiak, received a windfall of original Douglas fir single-pane windows from a neighbor, they took it as a sign to put dreams for a greenhouse in motion.

 

They chose the sunniest spot on the flattest part of their two acres in Marin County, Calif., for the 9-by-21-foot space. The couple worked together to remove brush, grade the land and build two retaining walls. Kodiak milled the lumber for the greenhouse from a redwood tree on the property. In all, the project cost around $2,500.

 

Hinged doors and windows direct air flow which helps regulate temperature, reduce humidity and cycle carbon dioxide, essential for plant health.

 

The couple takes a more conventional approach to the greenhouse, using it as a garden workshop year-round, but it gets especially busy in the spring. In March, Christiana will seed brassicas like kale, broccoli and cabbage, along with onions and leeks. While she tends to the plants, her 7-month-old daughter often naps in a comfy chair set up in a sunny corner.

 

Soon, she hopes her daughter will join in the work. "I have a feeling it will be one of her favorite places, as it is mine," she said. "There is a tiny harvest basket and a little watering can waiting for her."” [1]
