Questions to ask before getting started

It's important to get any question you might have out before beginning a home addition project. For instance, you should consider the reason(s) as to why you've decided on a home addition. If you simply want to gain a little more free space in your kitchen, a simple layout change might make all the difference and you wouldn't need to undergo a home addition. Also, you'll need to see whether or not your land permits you to extend your home.

Most popular kinds of home additions


Home extensions and additions come in all shapes and sizes. Besides being able to pick what your addition looks like, you'll surely add what you consider useful and beneficial to your current living situation. Here are the different kinds of additions our home addition contractors can help you with:

Conventional house extension

A conventional house extension is typically a multi-room addition. Whether it be a lateral extension or extending your home into the backyard, they can essentially be done in the same way. Your home addition can be done on piles or on a foundation, all depending on your budget, and whether or not you'd like to have a bigger basement or crawlspace. Although these kinds of extensions are typically expensive, they have a great return on investment.

Bump Out

Bump out home additions are great to add a little more space to your regular living space - whether it be to make your kitchen a little bigger or to enlarge your living room. Your bump out might end up just as big as adding an additional room to your home, but generally, a bump out addition is to simply add more square footage to existing space within your home. 


Sunroom additions are great. They add general living space to your home and let you enjoy beautiful sun rays. Keep in mind that there are many kinds of sunrooms out there. Is this addition one you plan on using year-round or only during warmer months? Depending on what your needs are, you can opt for a four- or three-season sunroom, a solarium, or even a screened porch. Each option out there requires a different amount of work, and, of course, sunroom costs will vary accordingly. 

Second Storey

Your home addition project might entail adding a second storey. Perhaps you want to go ahead with this project so everyone has their own bedroom, or you might even convert your home into a bi-generational one by adding a second storey - like the Gilbert family.

No matter the reason for your second storey addition, it's important to take a look at the cost of adding a second storey before planning something that's above your budget cap, as well as talking to professionals - like architects and structural engineers - to properly assess your reno project's feasibility.


That's right! Adding a garage to your home is considered a home addition. Although you might not live in it, the garage will be used in some way or form. You might want one because you finally wanted to have a workshop where you can do some woodwork, or maybe as a place to store all your family's outdoor activity sets. In most cases, people opt to get a garage because they finally want a space to store their car when the weather outside is not so great. If you don't need a full-fledged garage for your home, you can also opt for a carport

Keep in mind that adding a functional garage to your home can also allow you to add a room above the garage and make your addition twice as functional. Of course, this will cost more, but it all depends on your needs and budget. Various garage costs might influence your final choice. 


House Lifting

If your home doesn't have a basement, you can opt to lift your home in order to add more living space. Whether you simply want more space, would like to add a bachelor, or turn your home into an inter-generational home, house lifting will surely increase your home's market value. However, this kind of addition is quite rare as its costs are fairly high in comparison to other home addition options. 

Converting Your Attic

Opting to convert your attic is also an option. If the space is unused, why not? You can turn it into extra living space for everyone or even a bedroom. Ideally, your roof's slant should be at a 45° angle and the ceiling must be of at least 7 feet high for half the surface area. Of course, this excludes the physical ceiling materials and flooring. If ever your attic doesn't abide by these standards, you can always lift the roof to make space. This kind of addition is quite complex and will need the help of a structural engineer. Although costs may seem high, they are usually lesser than home extensions on a foundation.

How much does a home extension cost? 

The cost of a home addition can vary according to many different factors. Will your home addition project be a turnkey project or will it be unfinished? Is the addition a lateral or a vertical one? Will it be on piles or on a foundation/concrete slab? Besides all the different materials you can choose, those are the main cost dictating factors. A sunroom addition might end up costing less than adding a room, but that will depend on the kind of sunroom you've opted for and the materials used. Your home addition can start anywhere around $120/sq.ft. and go up above $220/sq.ft.. Each project is different.

Planning your home addition

Planning out your home addition isn't simply getting plans done and beginning the renovation process. There's a lot to consider. What exactly are you planning to add to your existing structure? Do you need to get permission from your city? Are you even allowed to follow through with the project? And much more. 

Here are the steps to begin your home addition project:
