Home Additions in Winter Garden, FL
Designed in 3D, permitted with the right Orange County or city office, and built by a licensed Florida general contractor that also holds its own plumbing license.

Home addition projects in Winter Garden
Most Winter Garden additions are about the lanai or the in-laws. In Horizon West, Stoneybrook West and Summerlake, owners want to enclose part of a covered lanai as a family room or office, or add a downstairs suite so a parent does not need the stairs. Near Plant Street, older homes with two bedrooms and one bath gain a primary suite or a second bath at the back of the lot. Many owners would rather add on than give up a neighborhood, school zone or commute they like.
What changes for a home addition in Winter Garden
In Horizon West, the association's architectural review usually has to approve an addition, including roof material, colors and windows, before the permit is filed with the Orange County Division of Building Safety. Inside city limits, the permit goes through the City of Winter Garden Building Department, and the Notice of Commencement is recorded with the Orange County Comptroller. A lanai enclosure counts as new conditioned space, so it needs engineering and energy calculations. From our Kingspointe Pkwy showroom it is about 20 to 30 minutes via SR 429 or the Turnpike.
Local details we plan around
- Horizon West is unincorporated Orange County, so a Winter Garden address there means a county permit, not a city one.
- Older homes near Plant Street may have raised floors, older drain lines and original wood floors worth protecting during the work.
- Horizon West homes are often 10 to 20 years old, the age when builder showers, cabinets and flooring typically start failing.
- Two-story plans in newer neighborhoods put bathrooms over living space, so waterproofing and leak prevention upstairs are a priority.

Scope
What the work includes
Feasibility and zoning check
Before design, we review your lot survey, setbacks, lot coverage limits and HOA rules to confirm how much you can build and where it can go.
Design and 3D rendering
We design the addition to match the roofline, windows and finishes of the existing house, and show it in 3D so you can see the result before engineering.
Engineering and permit drawings
Licensed design professionals prepare structural plans and energy calculations. We submit the permit package and respond to any reviewer comments.
Foundation and slab
New footings and slab, tied into the existing foundation with doweled reinforcing, with termite pretreatment and a vapor barrier under the new concrete.
Framing or block walls and roof tie-in
Concrete block or wood framing to match the engineered plans, new trusses or rafters, and a roof tie-in that sheds water and matches the existing roofing.
Plumbing, electrical and HVAC
New bathrooms and kitchenettes plumbed under our own license, new circuits and panel review, and air conditioning sized for the added square footage.
Our process

The same five steps on every kitchen, bath and renovation. Online requests get a call back within 24 to 48 hours.

We visit you at home
We measure the space, note where plumbing, gas and electrical run today, and ask how you use the room. The design starts at this visit.
- 02
3D design rendering
Your measurements become a 3D model, so you see the layout, cabinet heights and finishes before anything is ordered or torn out.
- 03
Material selection
You choose cabinets, counters, tile and fixtures with our designer in the Kingspointe Pkwy showroom, against the final design.
- 04
Ordering and permits
We order material, check every item against your selections, and pull the permits the scope needs.
- 05
We build, then walk it with you
Our crew and licensed trades do the work and pass inspections. We finish with a walk-through, room by room.

"It is a pleasure to recommend Prime Construction / Kitchens for any of your home remodeling needs. Prime Construction helped me diagnose a problem with a wall in my garage related to a window leak. Prime Construction shared with me how I could address the issue myself and saved me the cost of a dispatch by their team. They were only concerned with helping me resolve my issue. I give my full recommendation to Prime Construction. Thank you"

FAQ
Home Additions in Winter Garden: questions
Do not see your question? Call us or send the estimate form and we will answer it on the phone.
Can I turn my covered lanai in Horizon West into a room?
Often, but it is treated as an addition, not a screen swap. The lanai slab and roof were usually not built as living space, so an engineer checks the footings and roof framing, and the room needs insulation, windows, air conditioning and energy calculations. Your HOA generally approves it first, then Orange County issues the permit. We confirm feasibility before design.
Is Horizon West part of the City of Winter Garden for permits?
No. Horizon West is unincorporated Orange County, even though many homes there use a Winter Garden or Windermere mailing address. Building permits for those homes go to the Orange County Division of Building Safety. Homes inside Winter Garden city limits, including the historic downtown area, are permitted by the City of Winter Garden Building Department.
Can you update an older home near downtown Winter Garden without losing its character?
Yes. We often keep original trim, doors and wood floors in the rest of the house while remodeling the kitchen and baths inside the existing layout. We look at the subfloor, plumbing and wiring during the in-home visit and explain where older systems may need replacing, so the estimate reflects what a house of that age usually needs.
How long does a home addition take in Orlando?
Most room additions take about 3 to 5 months of construction once permits are issued. Design, engineering, HOA review and permitting usually add 2 to 4 months before work starts. Garage conversions are typically faster because the roof and walls already exist. We give you a written schedule before construction and keep you updated as each phase passes inspection.
Do I need a permit for a room addition in Florida?
Yes. Any addition that adds space, changes structure or adds plumbing and electrical requires a building permit, engineered drawings and inspections. The permit is issued by your city building department if you are inside city limits, or by the county in unincorporated areas. As a licensed general contractor, we prepare and submit the permit package.
Can I build an in-law suite or ADU on my property?
It depends on your local zoning. An attached in-law suite with a bedroom and bathroom is usually allowed where additions are allowed. A separate unit with its own kitchen and entrance is treated as an accessory dwelling unit in many places, and rules on size, parking and occupancy vary by city and county. We check the rules for your parcel first.
