Building a deck can be a very pleasant home improvement - you will be able to enjoy more time outdoors at your home, and increase its value.
Before you begin, make sure you check the building codes for your area. Each code will be different based on the size of your lot, how high from the ground it will be, the area of country for frost lines, etc.
Building any home extension which isn't up to code can be a huge headache.
Planning and designing your deck should include where you are going to put your deck and what the deck will be used for.
You should also think about how much sun and shade the deck will have throughout the day. Trees are a nice addition for your home improvement deck, but be careful what types of trees. Some trees will drop a lot of debris on your deck. Berries on the trees can also stain your deck, your deck furniture and the railing.
If it is a very sunny spot, consider a trellis roof to help shade the area. If you are building your home improvement deck to house a spa, you will want to place your home improvement deck to maximise privacy.
Then sit back, relax, and enjoy your fabulous idea to build a deck!
