Home Additions
Also called room additions
Need more space without leaving the home and neighborhood you love?
Harris Contracting builds major home additions throughout South Florida, including primary suites, expanded living areas, bedrooms, offices and multi-room additions. We help coordinate the project from preconstruction and permitting through construction and completion.
Ground-floor additions expand the existing home, including bedrooms, primary suites, kitchens, family rooms and other living spaces. In Broward County the new structure has to be engineered for the High Velocity Hurricane Zone, permitted with your city, and coordinated with the systems already in your home. That is the part we manage for you.
What we build
- Primary suites and bedroom additions
- Kitchens, dining and family rooms
- Expanded living areas and home offices
- Multi-room additions
- Second-story additions when the lot cannot expand outward (see second-story additions)
- Attached and detached accessory dwelling units (see ADUs)





What a home addition costs
Pricing varies based on project type, size, complexity, existing conditions, structural requirements, and the finish level selected. Every project is built at one of three finish packages.
Products, allowances and available options are confirmed in the project proposal.
Pricing shown is for preliminary planning purposes only and is not a quote or construction proposal. Final pricing is determined after pre-construction/design and owner approval of the construction plans.
How long it takes
As a general planning guideline, construction for many additions may take approximately 4–8 months after permits are issued.
Design, engineering and permitting occur before construction and can add several months depending on the project and municipality. Timelines vary with project size and complexity, design requirements, permitting time, material lead times, site conditions and owner selections. These are general planning ranges, not guaranteed completion dates.

See all nine steps
- Lead intake and qualification. You send us your project information: property location, project type, approximate size and scope, desired timeline, anticipated investment range, and whether plans already exist.
- Initial qualification and site visit. We review the information and follow up. If the project appears to be a good fit, we schedule a site visit to review the property, proposed scope and existing conditions.
- Project evaluation and preliminary pricing. After the site evaluation we provide a preliminary pricing assessment that establishes a realistic construction investment range. It is not the final construction price.
- Pre-construction agreement and design. If you elect to proceed, we enter into a separate pre-construction agreement and coordinate the services the project requires, which may include surveys, zoning and feasibility review, architectural design, and structural and MEP engineering.
- Plan approval and final pricing. Once you approve the plans, we price the defined construction scope based on the approved plans, specifications, selections and allowances.
- Construction agreement. You and Harris Contracting execute the construction agreement based on the approved project scope and construction documents.
- Permitting and pre-construction planning. We coordinate permitting with the municipality and design professionals. While the project is in permitting, we work through selections, procurement planning and scheduling.
- Construction. Once permits are issued, we begin construction and manage scheduling, subcontractors, inspections, procurement and project coordination.
- Final inspections and closeout. Required final inspections are completed, punch-list items are addressed, and the project is closed out.

Does Harris Contracting handle design, engineering and permits?
Yes. Under a separate pre-construction agreement, Harris Contracting coordinates the pre-construction services a project requires, which may include surveys, zoning and feasibility review, existing-condition documentation, architectural design, structural engineering and MEP engineering. We then coordinate permitting with the municipality and the design professionals.
When do I get a final construction price?
After the site visit, you receive a preliminary pricing assessment that establishes a realistic construction investment range. Final construction pricing is prepared once the plans have been developed and approved by you, based on the approved plans, specifications, selections and allowances.

Don’t just take our word for it!
"Big thanks to Calvin and his entire crew for the work they did for me on my Dad's house. Always professional while there, quality work, and finished on time as promised. Would highly recommend."
"Calvin and the team at Harris Contracting completed 2 significant remodeling projects at my home. The first was a bathroom remodel and the second was the installation of a second floor mezzanine. I was impressed with the teams responsiveness and overall quality of the work. We had a few bumps along the way, but Calvin ensured any issues were addressed promptly. They showed up when agreed and also worked into the evenings and some weekend days to make sure the projects stayed on track. Having experienced some very difficult and unprofessional contractors in Florida, Harris Contracting are professional company, charging a fair price and delivered on my expectations. Recommended."
"Great company to work with, very professional. I will be doing more business with Calvin for sure. If you’re looking to get work done and not have to worry he is your contractor!"
