Base and Foundation Options
Creating a proper base or foundation for your greenhouse is important for structural longevity, pest control, and creating the right ambiance in your garden area, as well as contributing to overall functionality of the building. Bases can be as simple as a leveled out gravel or as complex as your imagination provides. Below we talk in detail about the many different options available for your greenhouse foundtion.
Do It Yourself (DIY)
Typically the most economic option for base preparation is to do it yourself. Nearly half of NW Green Panels clients elect to create their own foundation, perhaps due to the DIY attitude most gardeners and home improvement buffs share. The foundation pictured here was done by an actively retired airport engineer using professional survey equipment and graval compactor. Level, square, shovel, rake and tape measure are all tools typically used to create a base.
Requirements of a properly prepared base foundation:
1) Correct Dimensions - The pad or frame must be the right size to erect your structure.
2) Square - The greenhouse will not function properly if out of square, and a square building looks awfully funny sitting atop an askew base.
3) Flat and Level - If the foundation is not flat air gaps will be present beneathe the building. If not level the entire structure can lean slightly leading to roof misalignment.
4) Retaining Wall - If you are building on a slope, depending on the pitch you may need to include a retaining wall to keep the greenhouse from becoming a mudslide victim!
Hire a Contractor
Hiring the right contractor can really bring your landscape design dreams to life. For complex custom work we definitely recommend going with a trusted local contractor. They may even be able to bring unfamiliar techniques and materials to your attention.
NW Green Panels Provided Base
NW Green Panels is proud to offer the following base options:
1) Juniper Frame with Gravel Fill - Juniper is an abundant local material with exceptional disease and decay resistance with an untreated, in-ground life span of 30+ years.
2) Paver Stone Frame with Gravel Fill - Preselected or custom paver stones are formed into a frame then filled with gravel which is excellent flooring material for drainage and retaining thermal energy.
3) Paver Stone Pad - A paver stone floor slightly larger than the greenhouse footprint is layed out and set into place. Paver stone floors create a nice, finished look.
4) Cedar Floor - Your greenhouse could be set atop a specially built greenhouse deck or a complete cedar floor can be added over almost any previously mentioned base.
5) Custom - We are always open to taking on new challenges in foundation design.
