Why Zeta Construction

What you get with Zeta Construction

  1. 1

    Looks original

    We match the roof pitch and tile, the stucco texture, the windows and the trim, so the addition reads as part of the house and not as something added later.

  2. 2

    Structure first

    We verify the existing foundation, walls and roof framing and engineer how the new structure ties in. That is what keeps an addition free of cracks and leaks.

  3. 3

    Setbacks, permits and HOA

    We check what your lot allows before design and handle the permit package and the HOA architectural review.

  4. 4

    Room for the backyard

    Adding a suite or a great room is a good moment to add a covered lanai or the pool you want, with one builder and one schedule.

Adding space to your home in Tampa Bay & Florida’s West Coast

An addition is often the best way to get the home you want in the neighborhood you already love. The difference between a good addition and an obvious one is in the planning: what the lot allows, how the structure ties in and how closely the materials match.

What your lot allows

Before design we review your survey, zoning setbacks, lot coverage, flood zone and any HOA rules. That tells us where an addition can go and how large it can be, and it avoids redesigns after the permit review.

Tied into the house, not attached to it

The new foundation, walls and roof have to work with the existing ones. We verify the existing structure, engineer the connections and integrate the new roof into the old one with matching tile or shingles, so water and wind see one building.

Matched finishes

Stucco texture, window style, trim profiles, paint and flooring are matched so the addition feels original. Inside, we often take the chance to remodel the rooms around it so the whole home flows together.

FAQ

Home Additions: questions we hear

Another question? Call (813) 610-9805

Will the addition match my house?

That is the goal of every addition we build. We match the roof pitch and material, the stucco texture, the windows, the trim and the paint, and we tie the new roof into the existing one so it looks and performs as one.

Do I need a permit for a home addition?

Yes. Additions need a building permit and inspections, and the design has to respect setbacks, lot coverage and flood-zone rules. We handle the plans, the permit and the inspections.

How long does a home addition take?

Design and permitting usually come first, and construction of a typical room or suite addition takes a few months after that. You get a written schedule before work starts.

Can you add a second story?

Sometimes. It depends on whether the existing foundation and walls can carry the new load, which we verify with an engineer before design.

My community has an HOA. Can you help with approval?

Yes. We prepare the drawings, materials and colors the architectural review committee asks for and adjust the design if they request changes.
