Cottage Greenhouses

Gothic Arch Greenhouses is proud to introduce our new straight-eave Cottage Style Greenhouse. An elegant Victorian look with a steeper slope allows for extra ridge height inside the structure. Designed to accommodate additional hanging baskets and taller plants, this straight-eave greenhouse kit makes a beautiful statement in your yard. The masterfully engineered look matches many common roof styles and architectural designs of modern homes and buildings.

From small lean-to or greenhouses suitable for gardens with limited space to larger standalone ones for multi-acre plots, this Cottage Style Greenhouse complements all landscapes.

Gable Attached

Gable-attached greenhouses attach to your home or existing structure on their gable side. Utilizing the multiple size, color, and glazing options available, you can build a greenhouse to complement any home or landscape. We can place doors in the sidewalls or the gable end and increase sidewall height to maximize available floor space.


Lean-to greenhouses use the wall of an existing structure to create the fourth wall of the greenhouse, resulting in only having one greenhouse slope. Lean-to greenhouses are especially beneficial in colder climates due to being able to access your greenhouse without stepping outside.

Glazing Systems

Our Cottage Style Greenhouse Conservatory features a variety of glazing options to meet the requirements of your environment and climate.

  • 6mm Twin-wall Polycarbonate

    Our 6mm twin-wall polycarbonate is the most economical glazing material available. Very practical for a `growing greenhouse`, it offers 50% more insulation than single pane glass and diffuses sunlight, which may become too strong in the summer. It is essentially unbreakable, making it very safe in a family environment. The insulation will prevent the temperature in the greenhouse from changing drastically and result in the best possible growing environment for your backyard garden.

    R-value = 1.79, approximately 78% light transmission.

  • Five-wall Polycarbonate

    Our new 16mm five-wall polycarbonate offers unbeatable insulation at 50% more insulating strength than double pane glass and 80% more efficient than 6mm or 8mm twin-wall polycarbonate. Five-wall greenhouse covering is ideal for colder climates, for gardeners who grow specialty plants, or for those who prefer the most energy-efficient greenhouse to reduce heating costs.

    R-value = 3.03, approximately 62% light transmission

  • Single Layer Tempered Glass

    Our single-layer tempered glass is a tempered safety glass to minimize possible breakage or injury. The traditional look appeals to greenhouse gardeners and offers full light transmission to control growing variables. Single-pane glass is adequate for keeping a `cool greenhouse` in mild climates.

    R-value = 0.9, approximately 95% light transmission.

  • Double-insulated Glass

    Our double-layered insulated glass is a tempered safety glass to minimize any possible breakage or injury. Insulated double glass is the best of both worlds, providing you with the aesthetically pleasing look of a glass greenhouse and the insulation you may require for your specialty plants or hotter, sunnier climates.

    R-Value = 2.04, approximately 90% light transmission

You have the option of choosing one type of glazing to use throughout your structure or mixing and matching materials to optimize the interior climate.


Our heavy-duty aluminum frame is ideal for hobby residential and commercial greenhouses that require a permanent structure that complements an existing landscape. The standard greenhouse frame can withstand 85 mph winds and 30 pounds per square foot for snow loads. Mix and match glazing to suit your growing needs.
