Has your home become too small since you purchased it? Have your needs and budget evolved since? Well, if you love where you live, but are just tight on space, adding a second storey might be the right way to remedy the situation. Your neighbourhood will remain the same and you won’t have to deal with having to move all your belongings into a new home.
Though, home additions are major projects. To ensure the project’s success, it’s best to do business with the best qualified contractors. Find all you need to know for a successful storey addition below.
First and foremost, adding a second storey adds living space to your home. But, why not take the opportunity to give your home more of an imposing look?
Essentially, you want to live in a bigger home that fits our needs and wants, without moving out of our current place. When moving into a new home, we usually move into a new neighbourhood with new neighbours and don’t really know what to expect of them. Plus, moving into a new space might even be filled with hidden defects. Both risks not everyone is willing to take.
When you know and like your home, know your neighbourhood and neighbours well, and are hesitant about moving into a new space, adding a second storey is likely to be the best option for you. Doing so can easily turn your current home into your dream home.
Working with qualified contractors is sure to make the entire process pleasant.
Unless you find the ‘perfect’ home on the market, there are high chances that you’d still need to get renovations done in the new space. So why not just make your current home all it can be and avoid the inconvenience of moving?
A single storey home, like a bungalow, can usually be converted into a two-storey home or cottage. If you plan on adding a room to an existing garage, or adding a garage with a room above it, the process is a little different.
The cost to adding a second storey to your home can vary greatly depending on your home’s structure, where staircases are located, the desired finishing quality, your location, etc. If you want to drastically change the look of your home by changing its siding while you’re at it, costs will increase rather quickly as well. Costs truly depend on what you’re expecting as a finished product.
Here are the average costs we’re used to seeing our clients pay to add a second storey to their home:
Second storey addition (rough) |
$258 to $324/sq.ft. |
Second storey addition (turnkey) |
$300 to $360/sq.ft. |
To find out how much other kinds of home additions cost, take a look at our Home Additions Costs article.
Given the scope of the project, adding a second storey can take a rather long time. You’ll need to start counting the days from the moment you begin putting your ideas together. The plans alone can take, on average, 4 to 6 weeks. Then, it’ll depend on financing the project and getting permits. Afterwards, it’s all about putting everything together and getting the contractors to start working on the project.
Most of the work to be done can be done without you leaving your home. Though, your roof will be removed at the beginning of the project to allow to build the upper floor walls. You’ll therefore need to camp elsewhere.
Undergoing a project of this scope requires a lot of time and energy, but it’s oh so worth it in the end! The key to a successful storey addition is to be surrounded by the right people right from the get-go. Of course, everyone wants to work with only the best and avoid any headaches! That’s why it’s imperative you get your structural assessments and plans done by highly qualified professionals.
We strongly recommend you work with independent professionals when it comes to getting plans drawn up, when load calculations need to be done, etc. as they’re not tied to a specific general contractor. Getting independent professionals to do that kind of work means you’ll be free to get quotes from as many contractors as you’d like – thus being able to freely choose which contractor you’d like to work with. Hiring a professional with ties to a general contractor leaves you no choice but to work with them. If something goes wrong when working with independent professionals, you’ll be able to pinpoint where everything went wrong – whether it be the contractor or the architect or structural engineer’s fault.
Be sure to get qualified contractors to quote on your storey addition project. Don’t just ask for quotes from anyone you can find. It’s a rather important project, so you’ll want only the best contractors in town. Meeting with more than one – we believe three is a good number – will give you a better idea of what your overall cost will be, as well as allow you to figure out which contractor is best for you.
Feel free to ask questions! A trustworthy and qualified contractor won’t shy away from answering any questions you might have. They’re also likely to put you at ease. You can ask them about their legal history, their licenses, insurance policies, warranties, etc. You should also ask for past client references. Take a look at our article on 13 Questions to Ask Contractors Before Settling on “The One”.
