How Can We Help?

Premier Home Addition Expertise at Third Dimension Design

Expanding any portion of your home can be challenging, especially without visual aids to really see the potential final product. But, Third Dimension Design is here to change that with our comprehensive design services. We’ll discuss your goals for the new space and make suggestions on how to use the new square footage effectively. Once we’ve determined exactly what you’re looking for, we’ll start drafting up the blueprint. This technical drawing will highlight everything from measurement specifications to windows and doors—turning your thoughts into a to-scale floor plan.

For those who prefer to see things from a more direct perspective, we also offer 3D renderings for your home addition project. This will allow you to view the entire space as it connects with your home and experiment with various paint colors, flooring options, furniture placements, and more. Think of this as your own personal virtual reality of your new home addition.

Expand Your Space & Enhance Your Lifestyle

Hear What Our Customers Are Saying

David is amazing! There were things along the way that I did not understand, and he always took the time to explain.

Kris M.

“David has drawn plans for the last few projects I have completed. It was nice to have him throughout the permit process. David also completed an as-built on an existing property which I was having a nightmare dealing with the county on and David was able to get it permitted.”

Nick M.

“Quick to respond. Knowledgable, helpful and thorough. Would definitely use them again!”


“Third dimension is one the best companies that I ever worked with. They are fast at responding. They are very good in helping to solve your problems. The best!”

Dimitri G.

“I would definitely recommend Third Dimension Design to everyone. Their prices are reasonable. David did a great job explaining everything to me when we hired him to design a front and back addition to our house. He also designed our pool. We are very happy with the process and how our new additions turned out.”

Home Addition Design FAQs

Remodeling your home is an exciting time, especially if it means that you’ll receive an entirely new room or wing of the house to take advantage of. But amidst all the excitement are the underlying questions. At Third Dimension Design, we’re here to answer any and all questions you may have. If you don’t see your question below, please reach out to us directly.

Absolutely! Third Dimension Design has a network of contractors we recommend to homeowners looking to remodel their homes and break ground on a home addition. Each of the contractors we partner with is licensed and insured and ready to help turn your vision into reality. Contact us today to discuss our rates for connecting you with a reliable and trustworthy contractor.

The cost of a project varies based on the scope of work and your specific goals. Typically, most projects requiring detailed plans start at around $3,000 or more. Considering the significant benefits and added value a remodeled home brings, this investment is relatively modest. We’d be delighted to schedule a meeting with you to discuss the specifics of your home addition project and provide a personalized quote based on your needs and vision.

We certainly can! While our blueprints are intended more for design purposes, allowing you to see what the space will look like in real-time, we will take measurements if you prefer a more accurate and specific rendering. When we arrive for your initial consultation, simply ask us to include dimension-specific information, and we’d be happy to do so.
