Your Family Outgrew the House. This Is the Upgrade

September 09, 2026•3 min read

You started in a smaller house. Then the kids came, or the kids got bigger, and somewhere along the way the house that used to fit stopped fitting. If you're shopping for homes for sale in Round Rock, Texas with an upgrade move in mind, 1100 Celtic Cove in the Hidden Glen subdivision is worth a look.

This is a 3,900 square foot home in West Round Rock with 5 bedrooms, 4 full bathrooms, a dedicated office, a media room, and an oversized lot over .30 acres — the kind of lot size that was common when this neighborhood was built in 2004 and is much harder to find in newer construction today.

The Character Difference

A lot of newer Round Rock neighborhoods, built in the last decade or so, lean toward open, tube-like layouts. This house predates that trend. Large windows, wood floors, a gas fireplace, and real architectural detail throughout give it a level of character that's harder to find in newer builds at this price point.

Walking In

The dedicated office sits right off the entry, with high ceilings, French doors, transom windows, and its own door out to the front. Past that, a formal dining room leads back into the main living space, then into a kitchen built for actual daily use: granite countertops, a gas cooktop, a large window over the sink, and a breakfast nook for mornings.

Downstairs Layout

Two bedrooms sit on the main floor, including the primary. The primary bedroom has a coffered ceiling and a large bay window overlooking the backyard's old growth trees. The attached bathroom includes a walk-in shower, a separate jacuzzi tub, and separate vanities. A secondary bedroom sits close to the primary, which works well if you have a younger child you want nearby.

The Three-Car Garage

The garage includes its own dedicated window and enough space for three vehicles, a home gym, or both. A built-in water softener is already in place — a genuine upgrade for anyone new to Texas, where hard water is standard.

Upstairs

The upstairs holds two more bedrooms and a large flex space that works as a playroom, a game room, or a teen hangout, along with a fully dedicated media room with built-in reclining seating and surround sound wiring already run. One of the upstairs bedrooms doesn't include a closet, though it does have its own adjoining bathroom for added privacy.

The Backyard and Location

The backyard carries the same old growth trees seen out front, with a covered patio, ceiling fan, and enough separation from neighboring lots to avoid feeling closed in. This home feeds into Round Rock High School, one of the district's original high schools and A-rated.

The Bottom Line

3,900 square feet, 5 bedrooms, 4 full bathrooms, a dedicated office, a media room, a three-car garage, and an oversized .30-acre lot in a neighborhood built for space rather than density. If your current home has run out of room, this is the kind of upgrade move worth walking through in person.
