Professional, permit-ready residential design for homeowners expanding, reconfiguring, or upgrading their existing homes.

Expanding Instead of Moving?

For homeowners through the Niagara Region and surrounding areas, we design permit-ready:

  • Rear and side additions

Our renovation and addition services are designed for homeowners who want clear guidance, reliable communication, and permit-ready drawings prepared correctly the first time.

  • Measured drawings of your existing home
  • Zoning review and buildable footprint confirmation
  • Concept floor plans tailored to your needs
  • Detailed revisions and exterior elevations

A Clear, Structured Approach

Our process has been refined over 30+ years and over 7,500 completed designs 

1. Initial Consultation (Free)
We review your goals, property information, photos, and ideas.

2. Zoning & Site Review
We confirm setbacks, buildable area, and site limitations early — eliminating surprises later.

3. Measured Drawings
For additions and renovations, we measure your existing home before design begins.

4. First Draft & Revisions
Concept floor plans are prepared and refined through detailed feedback and revisions.

5. Detailed Development
Structural design, building code requirements, and cost efficiencies are integrated from the beginning; not added at the end. 

6. Finalizing for Permit
We prepare complete, construction-ready blueprints, sign and stamp them with our BCIN number, and provide all required documentation for submission.

Designed With Experience. Delivered With Accountability.

Many homeowners experience delays because calls aren’t returned or revisions take longer than expected.

We prioritize:

  • Direct communication with our design team
  • Prompt responses, no answering service
  • Clear timelines and expectations
  • Thorough internal blueprint review before permit submission

We design with both creativity and constructability in mind; “a pencil in one hand and a hammer in the other.” as Hank likes to say.

What Our Clients Say

I spoke to Hank years prior about a possible addition our family was planning. Hank stood out as honest and approachable. Although our timeliness and plans changed, when we were ready, Hank eagerly took our long awaited phone call.Hank and his entire team were so easy to work with. Hank really listened to what we wanted and talked us through our hesitations and many questions. The team was efficient and delivered on deadlines. We loved the design so much that we accepted their first draft proposal! Designer Justin kindly and quickly made a few adjustments for us a few weeks later without issue and made sure we had different options to choose from. Emily was always a pleasure to deal with in administration and accounting. I can’t thank everyone at Nauta enough for providing a design that will add value and function to our home, we would absolutely use their expertise in the future and highly recommend their service.

I just wanted to thank you for providing Chad, Emily, and I with an amazing Project Management Team to help us through this huge venture. Ian and Dan's commitment to ensure quality work is evident in the selection of trades men and their attention to every detail pertaining to the build far exceeded my expectations, further making this undertaking a seamless process. We absolutely love our new home/Granny suite!

Catharine R.

Wainfleet, ON

As we are approaching the end of our renovation / addition, we'd like to pass on our 'thanks for a design very well done'. As you know, success is always based on good design and plans, and by the number of comments we've received, Nauta Home Design shares in those accolades - you have taken a standard 'survey' house and made it our custom home. The great room viewing the Niagara escarpment is most impressive. What we are most pleased with is how NHD was able to take our ideas for our lifestyle, and interpret that into a detailed design that works. The 'creative' process was actually enjoyable, as you helped guide us through and make good choices. Our builder, Homes By Hendriks, had no issues with the plans, and even with the changes we made along the way, you and Hendriks worked well to keep the project moving smoothly. Referrals are always the best method of choosing a designer; its how we found Nauta. We'd be pleased to show our home to any of your clients.

We are so happy with our decision to work with you and the Nauta Team on our recent renovation project. Nauta Designs has truly unlocked the full potential of our home while respecting our budget by offering creativity and expertise while ensuring we maximize our return. My wife and I are sincerely grateful for your onsite support while dealing with the Halton Conservation Authority.Your experience and depth of knowledge during our discussion with them made the world of difference in getting the design approved. We would have been so disappointed otherwise. Thank you! True believer that the greatest compliment you can offer a service provider or sales individual is a referral. We have shared our positive experience with various acquaintances and loved ones who can't wait to see the final transformation; a few of which are looking to renovate their homes and plan to give you a call. I am confident that you will take great care of them as you have us!

Everything worked out great with our addition. We will send you some photos when we get a chance. We have taken lots along the way. People walking and driving by stop and admire the house often commenting to us on how good the house looks. They ask when are you moving in? No one can believe it is an addition.

I would recommend your firm to anyone building a home. I am still baffled at how many people have probably been declined their dream home because they didn't have your vision and tenacity for you clients.

We are so happy with Nauta Home Design and how they helped transform our home. Hank was professional and had a vision as soon as he stepped on our property. We could not be happier with the end result. Thank you for being a part of the journey!

Nauta Home Design provided quality work and consulting during the design and preparation of our homes garage & patio addition. Justin was great throughout providing continuous updates and tweaks to our drawings, answering questions and preparing us for the permit process. Greatly appreciated his work! I would recommend!

Jon W.

Port Colborne, ON

I’ve done several builds with the Nauta team over the last few years and will likely do several more. Each time Hank and his staff demonstrate a vast knowledge of the OBC, latest design trends, clear communication, offering professional advice and additional engineering when required. Hank has driven hours to meet myself and clients several times. Justin is always quick to respond and has made me feel backed and well supported throughout design approval/permit application process. Nauta truly designs with site conditions, architectural control guidelines, and client’s best interests in mind, making Nauta Home Designs my go to Designers for Custom home design.

Victoria Harbour, ON

We recently had the pleasure of working with Hank, Justin and the Nauta team.Each interecation we had was wonderful. From the first phone call and with every email or phone call between Hank and Justin. We worked with the Nauta team during Covid and we never felt as if the quality of service wavered. The Nauta team designed the perfect plans for our family and we are very satisfied with every aspect of the design. I think what I appreciated the most was that Hank understood this was our first time building and he always took the time to explain every aspect. He gave me knowledge of home building, defined terminology I did not understand and always listened to my concerns. We even had the team assist us with obtaining our permit which made the process much less stressful. With the help of the Nauta team we are on our way to building our dream home for our family!

We previously dealt with Justin on a new garage project. He walked us through all the steps from start to finish in designing a new garage to the actual drawings ready for permit. All of our change requests were handled immediately and with positive actions. I truly recommend Nauta Home Designs for all design & drawings you may need.
