Lanai & Pool Cage Extensions in Brandon, Riverview & East Hillsborough County

Make your existing screened area bigger, for furniture, a hot tub, or more shade, from a contractor who pours the concrete and matches your existing structure.

Lanai & Pool Cage Extensions
01

Love your lanai but wish it were bigger? An extension pushes your existing screened area outward, for a new hot tub, outdoor furniture, a shaded dining spot, or simply more room as the family grows. Because we pour the new concrete and build the aluminum ourselves, we can extend your slab, tie into your existing roofline, and match the structure so the finished space looks as if it were always that size.

02

Most extensions run around $15,000, and a typical job takes about six to eight weeks from signed quote to finished space, including permitting, concrete work, and inspections.

03

Todd has extended lanais and pool cages across East Hillsborough for decades, including some tricky ones, framing around a chimney, building over an existing pool deck, and tying a new insulated-panel screen room onto an older cage. Whatever your starting point, we handle the design, the concrete, and the build, so you deal with one company from the first drawing to the final inspection.

Three Things That Set How Far You Can Extend →

Three Things That Set How Far You Can Extend

How much bigger you can go is not really about what you want; it is about three limits on your lot. We check all three before we quote.

1

Setbacks, property lines, and easements

The county sets how close to your property line you can build, and utility easements can cut into the yard even when the line is farther out. These usually decide the maximum footprint, especially on newer, tighter lots.

2

Roof width and span

Extending the roof adds span, and past about 16 feet in width, the structure needs a heavier gauge of aluminum, which raises both material costs and manpower at installation. We will tell you where that line falls for your design.

3

HOA rules

Your HOA may limit the size, the roof color, or the roof type. We provide all the documents they need for approval, but checking their rules early keeps the project from stalling after you have already fallen in love with a plan.

What we see across Brandon, Riverview & Valrico

Most extensions we build are for homeowners who love their lanai but have outgrown it, a new hot tub, more furniture, or a growing family. On the older, larger Brandon and Valrico lots, there is usually room to extend outward. In the newer, tighter Riverview and SouthShore subdivisions, setbacks and easements are the real limit, which is the first thing we check. Reviews from customers who have doubled the size of their lanai are some of our most enthusiastic; an extension tends to be the project people wish they had done sooner.

How It Works, Start to Finish

5 Steps to a Better Space

1

Free on-site consultation

Todd measures, checks your setbacks, easements, roof width, and HOA rules, and tells you how far you can realistically go.

2

Design, engineering, and permit

We draw the extension, submit it to our engineer, pull the county permit, and provide your HOA documents.

3

Pour the new slab

We pour the new slab and footer first, wherever the extension needs them, before any aluminum goes up.

4

Build and tie in

We extend the aluminum structure and roofline to match your existing enclosure, then screen it with USA-made Phifer.

5

Inspection and walk-through

We schedule the final inspection and hand over your bigger, finished space.

What's Included

A lanai or pool cage extension generally includes the following.

Site review

Setbacks, easements, roof width, and HOA checked before design

New concrete

Slab and footer poured where the extension needs it

Engineering & permit

Stamped drawings, county permit, scheduled inspections

Matched structure

Aluminum and roofline extended to match your existing enclosure

Screen

USA-made Phifer screen, tied into the existing enclosure

What It Costs

A typical extension runs around $15,000. The biggest cost driver is width: once the roof span exceeds about 16 feet, the structure requires a heavier gauge of aluminum and more manpower during installation, which noticeably raises the price. Size, the amount of new concrete, and screen upgrades also affect the number.

$15,000

A typical extension takes about six to eight weeks from signed quote to finished space, since it includes permitting, inspections, concrete, and the build.
