The Vesta™: Greenhouse Home Design

Ceres new kit house is leading the way in energy efficient greenhouse home design. The goal of the Vesta™ is to provide you with a self heating, food producing home that is affordable to purchase, fast to construct, low maintenance and beautifully designed.

The Vesta™ Kit House

Why the Vesta™ Kit House?

Passive House Inspired

This energy-efficient greenhouse home design has strategic overhangs that shade windows in summer and allow for sunlight and warmth to enter in winter. 

A Greenhouse for Food & Heat

This energy-efficient greenhouse home design has strategic overhangs that shade windows in summer and allow for sunlight and warmth to enter in winter. 

Highly Insulated

Insulation wraps around the exterior of framing with 4" Insulated Metal Panels for walls (R-32) and 6" panels for the roof (R-48) 

Pre Fab Construction

No framing to cut, minimal material waster, and ready to build. Easy to order and fast to construct.

Ceres SunSense™ controller- greenhouse climate control

Integrated & Automated Controller

The Ceres designed Vesta™ controller makes the highly efficient structure a truly smart home.  The controller works as a standard thermostat to control your HVAC equipment, while also controlling greenhouse exhaust fans, heat, supplemental lighting and shading if desired. The controller can open and close strategic windows to move heat from the greenhouse into the main house on cooler days, and can open upper clerestory windows for cooling when needed on warmer days.

The Vesta™ FAQs

Yes. A forklift or telescopic handler is required for raising some of the large columns and placing the rafter beams. All of the main framing is bolted together (bolts supplied) and the lighter gauge framing is connected with bolts/tek screws.

Yes, expansion is possible. Because we are not specifically designing for expansion, design fees may apply.

Yes. The tightness of the building and high insulation value works great in both hot and cold climates. 

The Vesta can be built by the anyone with some construction experience or a local general contractor. Ceres is always there to provide guidance and support during the build process. 

Ceres offers several recommended floor plans at no cost. Owners can design their own floor plans or work with an architect/design-build firm to design their own layouts as well.

The client or contractor. This is not supplied by Ceres. We understand where we offer value and where the customer can find the same materials elsewhere and save money on extra shipping costs. 

No. The greenhouse comes with a ventilation system, which includes exhaust fans and intake louvres. A retractable shade curtain can be installed for additional cooling or removable shade paint can be used during the hottest months. We also offer a recommended HVAC system for the house and greenhouse, so you could have cooling installed in the greenhouse as well.

Depending on your power needs, the Vesta™ has space for a 4 kilowatt solar system (assuming 11, 375 watt panels) on the south facing greenhouse roof. With modern appliances and mechanical systems this could be enough to make the house net zero or net positive. Ceres can offer a solar layout design and recommendation for a small fee, to be installed by a local solar contractor.

We have space for 11 3.5×5.5ft solar panels on the south facing greenhouse roof. If this is grid tied, it may make sense to add more solar panels on the roof of the house as well.  While the orientation of the roof is not ideal, it is advantageous in certain locations to increase solar capacity.

Yes. The entire roof of the house portion is steel and slopes to the north approximately 1,000sqft. A rainwater collection system can be connected to the north side of the roof. Please note that rainwater collection can be illegal in certain locations, so we advise you to call your local authorities for regulations where you live.

Currently we have not sought out any certifications, but we may in the future. If that is something you would like to explore for your own home, we would be happy to support you in the process. 

At this point we are anticipating 2-3 months for delivery. While some of this time is for design and permitting, clients can be working on foundation, etc, once plans are complete.

If radon is detected a mitigation system can be installed under the slab before construction. This is dealt with by the homeowner or contractor, and does not fall under the responsibility of Ceres. 

In the greenhouse, venting is the first step and an optional dehumidifier will help with dehumidification in the winter months. The greenhouse heater will also help with greenhouse humidification loads.
