Our Home Addition Process
01
Consultation & Proposal
You contact NICKS Developments, and we schedule an on-site consultation to discuss your project details. We’ll gather information on the size and scope of the addition or extension to accurately determine a timeline and cost. Once we have all the details, we’ll draw up a contract proposal.
02
Design & Permitting
We handle all the home addition design tasks, including architectural and engineering components in addition to interior and exterior design. Our architects will create the drawings for the permit application, which we’ll fill-out and submit. Our reputation and experience in the industry help us streamline the approval process.
03
Finish Selections & Construction
In collaboration with our professional design team, you’ll select the best materials and finishes. Our designers will incorporate your choices into renderings, mood boards, and drawings for better visualization. Once you approve the final look, we’ll begin demolition and construction.
04
Final Walkthrough & Delivery
Following the final phase of construction, our team will clean up the site, removing and properly disposing of waste and debris. We perform a final walkthrough and make touch-ups if required. We also check the electrical and plumbing systems for proper functioning. We then reveal the finished results and let you enjoy your new space!

Frequently Asked Questions
The maximum square footage of your first-floor addition will depend on the size of your lot, the size of your home, and your local zoning bylaws.
The maximum size of your second-storey addition will depend on your home’s structural capacity, local zoning laws and building codes, as well as the scope of the addition.
Precise timelines cannot be determined until we discuss the full scope of the project. Factors such as the size of the addition and current condition of your home will affect the timeline.
We use fixed pricing at NICKS Developments. We discuss and finalize pricing and timelines after our on-site consultation.
While it is possible in some cases to live in your home during a second-storey addition, we do not recommend it. Second-storey additions involve major construction. The process is often more efficient and easier for both you and our team when you stay off-site during the second-storey addition.
