What to consider before adding a second story to your house?

When you’re thinking about hiring a second story addition company in San Diego or the surrounding neighborhoods, there are several important considerations you should take into account before proceeding with the project:

  • Whole-house impact: The function and the design of a second story addition have an effect on your entire home, from structural work to mechanical work and finishes. A great design will make the story addition look as if it had always been intended, so take the time to ensure that the story addition improves the curb appeal of your property and increases the functionality of your home.
  • Structural requirements: Your old roof system weighs significantly less than an entirely new second story on your home. You should consult experienced engineers able to calculate the amount of weight the foundation of your home and the main-floor walls can support.

When you’re making a second story addition to your home, there is usually a need for additional structural support in form of steel connection and plywood across main-floor walls in order for your home to meet code requirements.

  • Stairs: When adding a new story, you’re going to have to allocate some space from your main floor. This can impact the functionality of certain rooms, as well as the flow of the entire home. This requires some creative thinking and cooperation with a reputable architect who is able to find the perfect spot in your home for new stairs.
  • Doors, siding, and windows: Second story additions also raise the concern of the building envelope. Should you try to match the doors, sidings, and windows, or start completely over? Perhaps a half-and-half approach?

This will make you wonder if your entire home should get new siding. Also, if the windows are rotting, or if they don’t meet the energy code, you should replace them altogether.

  • Insulation: Adding a new story to your home is the ideal time to add new insulation. If your home was built in the ’50s, chances are there is no insulation within the walls, except maybe for newspapers. Opting for rigid insulation or fiberglass batts will greatly improve your home’s energy efficiency.
  • Finishes: The finishes of your home will probably dictate the finishes of the story addition in terms of materials, colors, and style. However, you can choose to revisit the finishes of your entire home to give your house a uniform, fresh look.
  • Roofing: When you’re making a second story addition to your home, the contractors will have to remove your entire roof. This is something you have to be aware of, as it will make living within your home impossible.

A project of this size always requires you to vacate your home. However, once you get back, you’ll enter a home that has double the space and that is completely ready for you to live in. If you are ready to take your home to the next phase, contact us for your second story addition project.

How to build a second floor on an existing house?

Adding a second story to your home is a complicated process that requires hiring experienced second story addition contractors in the San Diego region. The professionals will inspect your home, create a design, and devise a plan on how to add a story to your home.

However, there are also some aspects to consider before construction starts:

  • Perform thorough research prior to starting the project. The research should address possible design ideas, what second story addition company to hire, and your neighborhood building and zoning regulations.
  • Reach out to several contractors to receive information on their quotes and their construction process.
  • See about getting insurance to cover any potential damages, or inquire whether or not your contractor has some form of insurance.
  • Plan for potential unexpected furnishings and costs, and set additional funds aside for such occurrences.
  • Always go for a walkthrough of your addition with your contractors before finalizing construction.
