Studies have shown that may times putting money into the outside of your home produces a greater return than investing inside.
The following popular outside improvement projects will increase the curb appeal or value of a home: 
Adirondack chairs—Uniquely-American classic outdoor furniture is made entirely of wood and has a straight back and seat, which are set at a slant to sit comfortably on a hillside or mountain incline, but still be comfortable at any angle.
Gazebo—A gazebo can be freestanding or attached to a garden wall, roofed and open on all sizes to provide shade or shelter.
Planters and window boxes—Planters have become popular because they are both functional and ornamental. Additionally, some can be moved frequently to account for seasonal weather or just to create a change in scenery.
Picnic table—Picnic tables go well on a patio or a deck, but equally as well on the grass or under a tree in the yard. A traditional picnic table is all in one piece so that it wears well without a lot of maintenance.
Trellis—A trellis can function as a unique sun screen or it can be the framework for an outdoor hanging garden. Building it with pressure treated lumber can add life by minimizing rotting and other threats.
Trash can corral or compost bin—While many outdoor projects tend to be cosmetic in nature, here are two ideas that are both practical and pretty. With a trash can corral, you can hide unsightly trash cans and with a compost bin, you can reduce your own carbon footprint in a way that doesn’t take away from the visual appeal of the place.
