How to Add a Second Story to a House

Adding a second story to a home is a great way to add additional living space to a property without having to extend out onto your yard. This makes it a great option if you live in a built-up residential area where land comes at a premium or if you don’t want to lose any of the space in your yard.

By adding a second story, you can effectively double the square footage of your home, making it much more spacious and considerably increasing the value of the property.

There are some obvious benefits of adding a second story to your home, for example, the extra living space which will be created and the value added to the property.


Avoid the real estate market

If you need a larger property, then you might consider selling your own home and buying a new bigger one, but this comes with its own drawbacks. Selling your property is one of the most stressful undertakings in life. You will need to keep your home clean and tidy in case of viewings and then vacate the home while prospective buyers look around it.


When you find a property you want, you may have to compete with other buyers, or you may find that the homes you like are not within your budget. Often you will have to compromise, either on space, style, budget, or location. Buying and selling homes also cost a lot of money, which you could put to better use on extending your own home.

Stay in your neighborhood


Good neighbors are invaluable, so if you currently have neighbors you get along with, then it’s a big risk to move away from them and to an unknown where you don’t know your new neighbors.

If you have put a lot of time into building a support network in your community, then it can be very difficult to leave that and start over somewhere new. Your current neighborhood might also be better for your commute to work, or you may be close to friends and family.

Preserve outdoor space

Bear in mind that with an attic conversion, you will have sloping ceilings, which can make furnishing the second story a challenge and can make the space more difficult to use compared to if you had a full second story extension with flat ceilings.

If you have a large attic, you can use timber to frame and drywall the space to create separate rooms in the attic, such as a master suite with a separate bathroom or several bedrooms. You will also need to consider where a staircase can be added on the ground floor of the property in order to access the new attic space.




The first thing you need to do when thinking about adding a full additional story to your home is to find out if the local zoning laws will allow it.

Some counties and cities will have height restrictions for the total height of homes, and some may not allow the addition of an extra story at all. Be sure to find out what your local zoning rules are so that you don’t start investing money into a project that may not be possible.








You have the option of finding a prefabricated timber second story in a design of your liking, or you can custom-build your extension. A prefabricated timber frame will typically be less expensive and will be completed more quickly compared with a custom timber build.

Also, investigate online for reviews on previous works they have completed, and ask if you can contact previous clients to discuss their thoughts.

Choosing your builders will be one of the most important decisions you make when building a second story on your home because it is a huge financial commitment, and it can become very emotional and stressful when your family home is being worked on.


For families who are not used to living through extensive renovations, it may be worth moving out of the home for a few months, especially for a full second-story extension.
