  • Karen I.

    We’re thrilled with our back and side gardens. Our neighbors are in awe. Most of all thanks so much for the care and detail you and your team put in this project.

  • Tom C.

    We thought you should know that we’ve been inundated with compliments on the work you did on our entryway. Words like, tranquil, serene and peaceful were used.

  • Beth S.

    My neighbor, who is a landscaper, came up to me in my front yard and told me how much he and his wife loved our landscaping. They said they were inspired by the work.

  • Mary Lou R.

    Her quote was neither the lowest nor the highest but her professional architectural, thoughtful, creative plans for my yard made the decision an easy one.

Zone Nine Landscape & Design Inc. is a full service residential landscape design/build contractor. We provide designs and installations for medium to high- end residential clients over the Greater Houston Area.

After spending over twenty years working for two of the largest landscape firms in Houston, owner Sheila Elwell, B.L.A., founded Zone Nine Landscape & Design Inc. 14 years ago with a commitment to supreme service, quality, value and flexibility. She is very committed to doing things differently than other firms with good old-fashioned service.

We don’t nickel and dime our clients because we build proper contingencies in our bids and stand behind them. While we can’t at times control things lurking beneath the soil, we communicate every step of the way. We go above and beyond our job scope often to be sure we leave every outdoor environment beautiful and transformed. — Sheila Elwell B.L.A., OHRA, Owner, Zone Nine Landscape & Design Inc.
