I recently had my backyard remodeled. If you are looking to built a swimming pool then it is good to go for a vinyl lined one or a gunite concrete. Having a garden next to your pool would make it more homely and pleasing to the eye. Gazebos add a wooden charm to your poolside area. Putting a small table in it and sipping coffee next to it can be a real delight in the mornings. Having a outdoor fireplace is also not a bad idea. Having one near your pool can increase your entertaining capabilities. If you live somewhere arid it is good if you have a cactus garden too. It is easy to plant and adds a nice touch to your backyard. Throwing in a few sands can make it more cooler.
