Determine where you want the arch to go. Arches are often used to mark the entryway to a garden or backyard. An arch can, however, be placed in other areas within the garden to accent the landscape or garden design. If you are placing the arch over a walkway, measure the walkway to ensure that the opening of the constructed arch will be wide enough to span the walkway. Carefully assess the area for anything that may interfere with the height or the secure placement of the structure, such as low tree limbs or thick tree roots in the ground where the arch will be placed. Examine the ground around your chosen site to ensure that it is level and even enough for the placement of the arch.
Create a vision of how you want the finished arch and the surrounding area to look. Kit manufacturers provide a variety to choose from, making the possibilities relatively endless. If you have not already established an overall design or theme to your garden area, now is the time to decide what type of atmosphere to create and determine what arch design is the best fit for your vision. Do it yourself wooden arch kits can be purchased in elegant designs, reminiscent of English style gardens. They can also be purchased in oriental style designs that can be used to accent a Chinese style rock garden. Arch designs can be as sophisticated or rustic as you choose.
Consider the arch’s durability. You garden arch will need to be able to stand up to the weather conditions of your climate. Pressure treated lumber is best for standing up to the elements. Sealant will need to be used on the wood once a year in most climates. When purchasing your kit, find out if the arch is designed to be planted into the ground or bracketed to an above-ground surface. Staking the arch into the ground will generally provide the structure with more integrity, and will reduce the chances of it being knocked over and damaged in strong winds.
