Influential Factors

Several factors go into the creation of a porch. Building one yourself can come with a lot of learning curves, while hiring someone else means you're on their schedule. One of the best things about building something by hand is the satisfaction you'll get every time you look at it.

DIY Vs. Professional contractors

Building a porch on your own absolutely requires some knowledge of carpentry and the operation of power tools. It is also physically difficult to do this on your own; make sure to enlist the help of others who can follow directions. Doing it yourself will save you on labor costs but may cost you more in build time depending on how much time you have.

Professional contractors will work with you to draw up a layout, pick materials, and set up a deadline for completions. Hiring a reputable company takes the stress of getting permits off your shoulders, and you won't need to buy tools you might never use again.

However, with hired help, your availability can affect timely completion. If you aren't home to help make last-minute decisions or let the contractors in to get to the breaker, it'll cause a setback. Experienced contractors can even have the skills to set up electrical wiring too for the addition of fans and lights.

Communication is a huge factor in any build, whether doing it yourself with friends or working with a hired contractor. By aligning schedules and being available to make last-minute changes during business hours can save you a day or two. Also, communication can help prevent work injuries since everyone is on the same page.


As you consider the size of your porch, take a look at your home. Where would you like it to go? Is it going to be a single usage area or a multiusage area with a lot of foot traffic? Reviewing your property line map will give you an idea of which areas to focus on.

A single usage porch can be placed on the front of your home and adorned with comfortable sitting chairs and a small side table. These types of porches are good for smaller homes that don't intend to have a lot of people over at once. Plus, who wouldn't want to sit in the shade and enjoy some quiet downtime?

On the other hand, a multiuse porch will be a big hit for large gatherings and is essentially another living space. In this sort of space, you'll be able to put a dining table, multiple chairs or loveseats, and rugs without worrying about the elements touching them. Porches of this size can be used for dinner gatherings, birthday parties, and holidays.

The complexity of design

The complexity of your porch's design can be anything from size to style. Are you looking for a wrap-around porch? Do you have a historical home and need to stay within particular parameters?

Availability of materials and Tools
