Six Things To Consider Before Adding a Second Story to a Craftsman Bungalow

1. Foundation Requirements – Adding a second story generally doesn’t require excavation, but it does need a strong, sturdy foundation. Most Denver craftsman bungalows have load-bearing brick walls on a pore foundation which are great for single-story homes. But, they aren’t always a good candidate for adding a second story. If this is the case, you may be able to reinforce your walls or there’s always the option to pour a new foundation.

2. Zoning – Confirm that the zoning lot where your home is located lets you add a second story to your home. If there are limitations on pop-top additions, then you’ll want to know that upfront before investing more time or money into the project.

3. Alternate Housing –  If you are adding a complete second story addition then your entire roof will need to be removed, requiring you to find alternate housing during construction. If you are simply looking to add an additional bedroom or office on the second floor, it may be possible to consolidate to one area of your home during the build.

4. Timeline –  Adding a second story to a craftsman bungalow is a major construction project that can be time-intensive. Make sure to plan your timeline accordingly.

5. Impact on the Neighbors – When you build up your home you’ll likely have an impact on your neighbors. Not only will they have to deal with the noise during the construction process, but your addition may also change or even block their view. Your newly designed home could also affect the amount of sunlight they get in their home and yard, etc.

6. Future Plans – Most homeowners that build up do so because they love their home and want the space. But, if you are planning on selling your home in the next few years, you may not see a large return on your investment. Always be sure to compare the projected value of your home after your remodel to other homes in the area, keeping in mind any moves, to maximize your return.

Craftsman Bungalow Second Story Addition Benefits

Popping the top of your craftsman bungalow or building a second floor addition and craftsman bungalow allows for complete customization. With the extra space, you can change your existing layout and get the home of your dreams. You could move all of the bedrooms upstairs or opt to modernize your home with an open floor plan. Building your home up will also give you a height advantage that simply isn’t possible with the traditional craftsman bungalow, letting you wake up to an even better view of the mountains.

Having more space can have a major impact on the quality of your life. You’ll also get the added bonus that the additional square footage that you get when you build a second story to your home will increase the overall value of your home.

In fact, you may find that adding a second story to a craftsman bungalow is more cost-effective than building a traditional addition onto the side of your home. Why? Because many times there’s no need to dig a foundation or do excavation work. This also means that you’ll get to keep all your backyard space for summer barbeques.

We used Factor to renovate a 1966 ranch-style house in Cherry Hills. Once we got to know the team and felt comfortable with the operation, what began as a kitchen remodel turned into a full-on 10-month renovation of the entire house. We absolutely saved time and money having the design group working out of the same office as the construction team. This allowed for a seamless and intuitive process that delivered for us on time and on budget. It is worth noting Factor has talent at the trade-level – Travis, our construction manager, is a real pro. They did a great job for us and I would highly recommend their services.

Wonderful experience with Factor Design Build on the complete interior remodel of our home.

Couldn’t be more pleased with the finished product and thoroughly enjoyed working with the Factor team. They were on top of it throughout the project and very communicative. Project was complete on the projected deadline. White glove service that was a great fit for our family.
