Increase-Your-Home-Value-on-a-BudgetWe run into a common scenario with our customers: they love their homes but need more space. Maybe they have a new kid on the way, a parent moved in, or they have too many cars.
One of the biggest hurdles for any home addition is the paperwork. The RenosGroup team handles the entire process for you to ensure your project is 100% compliant with local regulations:
* Zoning Bylaw Reviews: We ensure your addition meets setback, lot coverage, and height requirements for your specific Ottawa neighborhood.
* Building Permit Applications: We prepare and submit all technical drawings and structural plans to the City of Ottawa.
* Inspections: We coordinate all required municipal inspections during the construction process, from foundation to final occupancy.
It’s also not wise to try to renovate on your own for the sake of your health.
Renovations require putting yourself in dangerous situations, including heights, heavy lifting, and more.
You risk seriously injuring yourself by renovating as a solo project. Not only that, but you’ll be on the hook for paying the medical bills. That can spell disaster for your bank account.
Hiring experienced professionals is a must, especially for home additions. If you do a botch job or hire inexperienced contractors, you could damage your foundation. That could wind up costing tens of thousands of dollars to fix.
We’ve seen it all the time; customers want to save money, so they go with personal friends or hire a cheap service.
A few weeks/months later, they call us in a panic because their home is falling apart
To avoid this potential disaster, save yourself some stress and hire us from the start. Our crew boasts 25 years of successful experience renovating homes in Ottawa.
We’re also licensed and insured to do what we do. You’ll never have to worry about paying for expensive repairs due to mistakes.
It’s our goal to work based on your needs, not the other way around.
That’s why we offer free in-home consultations for every new client.
You’ll get to meet with our construction professionals for free. Spare no detail when telling us what you’d like to see from our work. We’ll take detailed measurements when we show up at your property free of charge. That will ensure the feasibility of what you want to get done with your property. Here are some of our most common home additions, but they’re by no means all that we can do.
A standard sunroom features all-glass walls and is accessible from indoors. You can think of it as a walled-in deck. We can further customize your sunroom with outdoor furniture, lighting fixtures, and more. Traditional sunrooms are not connected to your central heating and cooling system. That lends to the outdoorsy feel for those searching for an authentic experience.
A four-season room is a sunroom that has heating and cooling. For this reason, you can enjoy a four-season room all year round. You won’t have to worry if it’s excessively hot or cold outside, as your room will stay at your temperature of choice.
Are you big into gardening? Then you need one of our greenhouse-style sunrooms. It features similar construction to a sunroom but is set up expressly for gardens. A greenhouse provides ample light, humidity, and proper temperature levels for plants.
A screen room is similar to a sunroom in that it’s an outdoor living area that connects inside. The primary difference is that it uses mesh-screen windows/walls instead of glass. It’s a less-expensive way to achieve a sunroom and has an old-timey feel.
Creating a two-car garage. If your vehicle collection is growing, you don’t want to store them all in the driveway. With a spacious two-car garage, we can help you keep your precious vehicles safe and sound. We’ll expand your existing garage so that you can comfortably fit another car along with storage space.
Adding more storage space. If your garage is your primary storage hub, we can add more space just for that. Are there specific areas of your garage that you use for storage? Then we can focus our efforts on expanding those areas in particular. Our experts will scout out your garage during your free in-home consultation to determine what we can do.
Repurposing/converting your garage. Would you rather your garage become something else? Then we’re the team for the job. Let us know what you’re thinking, and we can help you repurpose your current garage. Whether you want to add another garage or go without, it’s up to you.
We can grant you that fantastic flexibility. If you’ve been working hard to save up for a few years now, why not treat yourself? You can go from a substandard bedroom to a luxury second-story master bedroom suite.
With our help, you won’t have to settle for a kitchen that’s too small.
You shouldn’t have to sell your home just to find a big enough kitchen for you.
Instead, we’ll work with your existing kitchen to make it just as you want it. Do you wish you had more counter space? Then we can add a custom island for you or add to your current countertops.
If your kitchen has an inconvenient layout, we can fix that through our additions.
We can rethink your entire layout with open shelving, islands, new appliances, etc. That way, you’ll have your dream kitchen without moving from your current location.
Another addition we do a lot is adding a second kitchen. Let’s say that you love to entertain guests in your sunroom at the back of the house. Your original kitchen is at the front, making it inconvenient for cooking for your guests.
We can add a second kitchen through a bump-out next to your sunroom. That way, you can easily prepare hors d’oeuvres and meals for your guests and family. We can add a grilling area too for cookouts and barbecues.
Kitchens aren’t our only use for bump-outs, though. We can also use them to add more rooms to your home. They can be bedrooms, storage rooms, bathrooms; you name it.
We can add chair lifts, ramps, raise/lower fixtures, and so much more.
Let us add functional living spaces for your loved ones with disabilities.
Do you have a hard time getting around your home in your wheelchair? Then you can rely on us to add more space to your home. We can expand your current space or add new ones to accommodate you. Homeowners who use wheelchairs need extra space to turn around and navigate corners.
We’ll take detailed measurements of your property during your free in-home consultation. That way, we’ll know exactly how much space we need to add to ensure your comfort. To learn about the cost of home additions in Ottawa more details about home renovation additions.
Home addition costs in Ottawa typically range from $350 to $450 per square foot. A standard 300 sq. ft. rear bump-out generally falls between $90,000 and $135,000. Second-story additions tend to start at $150,000+ due to structural reinforcement requirements.
From permit approval to final walkthrough, most Ottawa home additions take 3 to 6 months. Single-storey additions typically require 10–14 weeks of construction. Permit approval timelines (2–12 weeks) should be added to the front end of the schedule.
You always have the option of building your home addition yourself, however, we advise against it. If you are lacking prior experience and are simply looking for something cost-effective, there are better alternatives, such as renovating during the low season. By hiring a professional, you avoid having to pay for any repairs or replacements in the future.
Yes. Any home addition in Ottawa that alters the building footprint, height, or structural components requires a Building Permit. If your addition violates zoning setbacks or height limits, you’ll also need a Minor Variance from the Committee of Adjustment.
Like most renovations, the best time to build an addition is at the start of the summer months. With that said, a home addition can be started later in the summer or even the fall as long as it gets closed in before it gets too cold or snowed in.
Yes, in most cases. Second-story additions are popular for doubling living space without sacrificing yard area. Feasibility depends on your current foundation’s load-bearing capacity and local zoning height restrictions.
If you are building an addition, the foundation and architectural/design fees are usually the largest expense. Discussing your budget with a renovation expert will give you a better idea of what you can afford and the steps you can take to minimize the cost.
Yes, Architectural/Design plans are needed for any home addition. If you don’t have an exact plan in mind of what you are looking for, we’re happy to help! Our team is more than willing to provide direction and ideas on what will suit your space best.
Absolutely! As an area that gets used frequently, a home addition is one of the best ways to increase the value and square footage of your home.
Our service area consists of inside the city of Ottawa. Ex: Nepean, Kanata, Stittsville, Barrhaven, Hunt Club, Glebe, Gloucester, Orleans. Unfortunately we do not work in the outskirts of Ottawa or in Quebec side (not licensed in QC)
A bump-out addition is a small-scale expansion that extends a room outward by 2–6 feet, typically without requiring full foundation work. Common applications include expanding a kitchen or adding a master closet.dion Content
