The design of Santa Barbara 6ft or 9ft wide Deluxe Redwood Lean-To Greenhouse/Sun Room in Glass or Polycarbonate is charming and functional. Redwood is the perfect material for a Greenhouse, is unsurpassed as a garden structure, and is the most compatible with an upscale residential environment. No doubt, it is one of America’s finest greenhouses for gardeners and homeowners.

The Santa Barbara Deluxe Lean-to Glass / Polycarbonate Greenhouse/Sun Room is the best engineered redwood lean-to greenhouse available in the market today. Redwood is resistant to weather, insects, decay and should last a lifetime with no special treatment. High quality knot-free California redwood is carefully chosen for its beauty and durability. The studs and rafters in these deluxe models are double that of the Standard line. The modular sections are bolted together and the side panels are glazed with either 3/16 inch thick tempered glass or 6mm twin wall polycarbonate of your choice. The roof panels are twin-wall polycarbonate.

A lean-to greenhouse can fit into a narrow space against your house or garage. If located against your house it will reduce heating costs. If placed over a door or window the heat from your home can be utilized to maintain growing temperatures throughout winter. Another advantage is the easy access from your home into your greenhouse. Locate your greenhouse where it will receive the most sunlight possible from November through January.

Ask a Question
  • Can you custom make it 6x14? Can we buy it without the premium add ons and just get the wood and glass shell?

    YES, we can custom order a 6x14!  The pricing would be the same as the 6x16 - Deluxe Redwood Leanto, Pre-assembled glass panels.  Greenhouse kit only (no premium package).  Price: $8,500.  No refund, no return on a custom build.  Please call to order: 888-648-5333.

    A clarification just in case: the roof of all the Santa Barbara greenhouses is twin wall polycarbonate - they don't build anything with overhead glass.

  • What is the cost of a 6x12 Redwood lean to without all the extras (Premium Package)

    If you want to purchase the Santa Barbara Redwood Lean-to 6x12 without the accessories, the price is $7999.  Feel free to contact us at 888-648-5333 if you have more questions.
