A two bedroom 800 sqft second storey addition on a bungalow starts around $240,000 (with most of the main floor remaining as-is). A three bedroom 1,200 sqft bungalow with a main floor remodel (gut job) typically starts around $400,000. Read on to see the cost break downs and various options you may what to think of.
There are many factors involved in determining the cost for this type of project. There are four main cost categories involved with this complex project:
• cost of drawings and permits;
• cost to add the second storey itself on your bungalow.
• renovation costs for main floor
• Costs related to work on the exterior of the property.
Almost all municipalities will require that you have detailed construction drawings in order for a permit to be issued. In the province of Ontario a licensed architect or someone with a BCIN designation is able to provide such drawings. The drawings need to show all the structural engineering components and the new heat loss calculation for the new heating system.
Architect fees can vary greatly and go upwards of $30,000. Our fees are more reasonable and cost approximately $10,000. In the city of Toronto the permit fees are approximately $3,000 for this type of project. When designing your second story addition it is best if possible to avoid “minor variances”. A minor variance is required when a zoning regulation isn't complied with in your drawings.
Each property has its own set of “rules” based on bylaws for your area. The big ones are “lot setbacks”, “coverage” and height restrictions. For example if the zoning in your pocket only allows for 30% lot coverage and your new project requires 31%, you will need to ask for a minor variance at the Committee of Adjustment (CoA). With a committee of adjustment application there are additional costs that add up to approximately $6,000. This includes the cost to render a new survey of the property, the application fees and the services associated with the presentation to the committee by the architect.
There a a lot of construction details involved with adding another floor to your bungalow! It involves removing your entire roof, setting up the structural elements, framing the new floor system, walls and roof, installing windows and shingles and then finishing the interior and exterior of the second storey. A new staircase also needs to be provided – somewhere on the main floor where most logical. We also need to run new electrical wires, new plumbing drains and extend your furnace system to supply heat to the second floor.
The base price to build a second storey starts around $300 per square foot for the first 800 sqft of bungalow space. Additional square feet will usually cost around $200 a square foot. So, for example, an 800 square-foot bungalow pricing starts around $240,000 and a 1200 square-foot bungalow would cost around $320,000. This would include 3/4 bedrooms, one bathroom and a stucco finish exterior (for second floor walls). Adding another bathroom can add another $10,000 to $20,000 depending on the location of the bathroom and how “high-end” your finishes are.
When adding a second storey to your bungalow, most homeowners will want to remodel their main floor by removing most if not all of the bedrooms and creating an open concept floor plan. Most homeowners are surprised to hear that we can work with the existing floor by keeping your existing bathroom and kitchen and simply remove a few walls, which will keep project costs lower.
The main factors that will increase the cost of the main floor renovation include whether you need to to relocate or close off existing windows and if you want to increase the ceiling light from 8 feet to 9 or 10 feet. At the lower end of the cost spectrum, if you can keep most of your main floor “as is” and simply open up a few walls, we will still need to replace your flooring so that it’s consistent (finish floor doesn’t run under wall partitions). And you might want to add a centre island to your existing kitchen. This can cost as little as $15-$20,000.
If on the other hand you would like to gut your entire main floor and rebuild completely (new kitchen and powder room), this will typically run you between $80-$100,000 depending on the type of kitchen you put in. This also provides an opportunity to add insulation on the exterior walls as most 1950’s bungalows have zero insulation on exterior walls. Also, increasing the ceiling height on the main floor will cost around $10,000 to go from 8 feet to 9 feet
The final cost component for your second story addition project involves the work you plan on doing on the exterior. Some homeowners prefer to have the front of the house look new and consistent we can remove the existing brick on the front of the house and install a brand new brick or stone across the entire front as opposed to having your older brick for first 10 feet and stucco for the second floor. A new brick front exterior will usually add approximately $15,000 to the cost of the project.
Some homeowners would also prefer to stucco the entire bungalow such that everything looks consistent. Covering the existing brick on the main floor can also $15,000 to $18,000 to the cost of the project. Often with this type of project, you may want to consider remodelling your front porch and/or installing a new front door or replace your railings. Again, this can also add another $10-$15,000 depending on what you do. Another very popular idea is to add a garage to bungalow as most 1950s bungalows don't have an attached garage. Adding a garage on the side of the bungalow can add a significant amount of cost especially if you're also adding square footage above the garage to make your second floor larger. Cost will usually start around $50,000 but may go upwards of $100,000 for a double car garage with a full addition over the garage.
