Home Additions in Roswell, Alpharetta and Johns Creek

A new bedroom, a bigger kitchen or a primary suite, built to tie into the house you have and look as if it was always there.

Home additions

Home additions in Roswell give a family more room without leaving a street, a school or a neighborhood they like. The most common ones we build are a primary suite on the main floor, a larger family room on the back of the house, a bigger kitchen, and a room over the garage. An addition is the largest project most homeowners take on, so it starts with the questions an estimate can answer: what fits on the lot, what the city and the neighborhood allow, and what it will cost.

What fits on your lot

Every lot has setbacks, the distances the house must keep from the property lines, and a limit on how much of the lot can be covered. Many lots in Roswell, Alpharetta and Johns Creek also have slopes, trees, easements or a septic field that rule out one side of the house. On the first visit we look at the plat, walk the lot and tell you where an addition can go and roughly how large it can be. If the answer is that it cannot fit, we say so before anyone pays for plans.

Plans, permits and the HOA

An addition needs drawings: a site plan, floor plans, the foundation and framing details and how the new part ties into the old one. We draw or arrange the plans, pull the permits with the city and book every inspection. Many North Fulton neighborhoods have an architectural review committee that must approve exterior changes, sometimes before the city will issue a permit. We prepare the drawings and the material samples the committee asks for and allow time for its meeting dates in the schedule.

Matching the house

The goal is an addition that looks like it was always there. We match the siding, the brick or the stone, the trim, the window style and the floor height inside, so you do not step up or down into the new room. Where a material is no longer made, such as an older brick, we show you the closest options before you sign.

How an addition goes

  • Plans and approvals. Drawings, any HOA approval and the permits, with the price fixed on the plans.
  • Foundation. Excavation, footings and the foundation, inspected before the framing starts.
  • Framing and closing in. Floors, walls and the frame, then windows and doors, so the new rooms are weathertight.
  • Systems. Plumbing, wiring and heating and cooling run into the new space, with an inspection before the walls close.
  • Opening into the house. The connection to the existing house is cut last, behind a sealed dust barrier.
  • Finishes. Insulation, drywall, flooring, trim, paint and fixtures, then a walk-through with you.

Addition or basement?

If what you need is a family room, a guest suite or an office, a finished basement can give you the space for much less, because the foundation and the walls are already there. A primary suite on the main floor, a larger kitchen or more light in the main living space usually needs an addition. We price both if you ask, and say plainly which one we would choose for your house.

Living through it

You can usually stay in the house. The crew works outside for most of the job, parks where you ask, and keeps the site tidy at the end of each day. When the opening is cut, the dust barrier goes up first and the floors inside are covered.

Your written estimate

The estimate lists the plans, the permits, the foundation, the framing, the systems, the finishes and the connection to the house on their own lines, with the schedule beside it. Planning an addition in Johns Creek, where lots are larger and wooded? Tell us early, because tree protection and access for equipment shape the plan.

Questions about home additions

  • How long does an addition take?

    Most additions take a few months on site, after the plans, the permits and any HOA approval. A one-room addition on a simple foundation is quicker than a two-story one. Your written schedule shows each stage in working days, and we tell you at once if a date moves.

  • Will the addition look like it was always there?

    That is the aim. We match the siding, the trim, the windows and the floor heights to the house, and the plans show how the new part meets the old one. Some materials are hard to match exactly, and we tell you before you sign where a small difference may show.

  • Can we stay in the house during an addition?

    Usually, yes. Most of the work happens outside the house until the very end. We frame and close in the new rooms first, then cut the opening into the house behind a sealed dust barrier, so the noisy and dusty part inside lasts days, not weeks.

    Primary suite addition on the side of the house

    70 working days

    A growing family on a wooded lot off Medlock Bridge Road who needed a primary suite without losing the yard. The plans set the addition on the side with the most room, matched the siding and the windows to the house, and kept the old hall as the way through. The new rooms were closed in before the opening was cut, behind a sealed dust barrier.

What we check

What's really behind your walls

A remodel runs from the structure to the systems to the finishes you see, and most surprises start in a part you never see. Every estimate checks each one, and every quote prices them on their own lines.

  1. Structure

    The foundation, the framing and the beams. Moving a wall or adding a room starts here, and the plans show what each wall carries.

  2. Systems

    The plumbing, the wiring and the heating and cooling inside the walls. A remodel is the best time to update them, while the walls are open.

  3. Insulation

    What keeps the room comfortable and the bills down. Older walls often have little or none, and it goes in before the drywall.

  4. Walls, floors and ceilings

    Drywall, subfloor and trim. Soft floors and cracked plaster often point to water or movement behind them.

  5. Finishes

    The cabinets, counters, tile, fixtures and paint you see every day. They set much of the price and most of the look.

5 out of 5 stars

“We walked the framing with the project manager before the walls were closed, and he showed us where every outlet and light would go. Nothing about the finished room surprised us.”

  • 4 out of 5 stars

    Our addition took a little longer than planned because of the permit, but they told us the moment it slipped and every change order was in writing before any work.

  • 5 out of 5 stars

    The plans for our sunroom addition were ready faster than we expected, and they handled the permit and every inspection. The new room looks like it was always part of the house.

  • 5 out of 5 stars

    Our bonus room over the garage became a real bedroom with its own bath. The change order for a bigger window was written up and signed before they cut the opening.
