Costco, Home Depot & More Are Coming to Cypress: What’s Really Happening at Grand Mason?
If you've driven the Grand Parkway through the Cypress area lately, you've probably noticed something:
There is a lot happening out there.
One of the biggest developments now getting attention is Grand Mason, a planned approximately 400-acre commercial and mixed-use destination along the east side of Grand Parkway between FM 529 and West Road.
And two names are grabbing most of the headlines:
Costco and Home Depot.
A new Costco warehouse is already under construction. A new Home Depot is planned nearby. But those two stores are only part of a much larger vision for this stretch of the Grand Parkway.
Grand Mason's current plans contemplate retail, restaurants, entertainment, medical and office space, hotels and other uses across multiple phases.
So what's actually confirmed?
What's still just part of the plan?
And what could all this development mean if you already own a home nearby—or you're thinking about buying in Cypress?
Let's separate what we know from what's still on the drawing board.
Costco and Home Depot at Grand Mason: Here's the Quick Answer
A new Costco is currently under construction within the Grand Mason development along the Grand Parkway near Cypress. Current state filings describe a 160,000-square-foot warehouse and a separate 11,680-square-foot fuel facility. The filings list projected completion in November 2026, although Costco has not announced an official opening date for the new location.
A 134,808-square-foot Home Depot is also planned on the east side of Grand Parkway, south of West Road. According to the state filing, construction is scheduled to begin October 15, 2026, with estimated completion September 20, 2027. No official opening date has been announced.
Put the two warehouses together—not including Costco's separate gas station—and you're looking at nearly 295,000 square feet of major retail from just two brands.
But Grand Mason is much bigger than Costco and Home Depot.
What Is Grand Mason?
Grand Mason is a planned approximately 400-acre development being promoted by NewQuest along the east side of Grand Parkway between FM 529 and West Road.
Updated development materials show a multi-phase vision that could eventually include:
Major retail
Restaurants and services
Entertainment
Medical facilities
Office space
Hotels
Multifamily residential uses
Fitness and lifestyle uses
The development sits near growing communities including Mason Woods, Marvida and Elyson, with Bridgeland also part of the broader Cypress-area growth story.
That's an important distinction.
Grand Mason isn't simply a new shopping center.
The current vision is for a much larger commercial and mixed-use district that could develop over multiple years.
And that helps explain why major retailers are paying attention to this part of the Grand Parkway.
Where Is Grand Mason Located?
Grand Mason is planned along the east side of Grand Parkway (SH 99), generally between FM 529 and West Road, in the Cypress/north Katy growth corridor.
The location puts the development between large and growing residential areas on both sides of the Grand Parkway, including Mason Woods, Marvida and Elyson, while providing regional access to Cypress, Bridgeland, north Katy and surrounding communities.
That location matters.
The Grand Parkway isn't just carrying people through the area anymore.
Increasingly, businesses are building destinations along it.
First Up: A New Costco Is Under Construction
Let's start with the project everyone seems to be talking about.
According to state project filings and current reporting, the new Costco includes a roughly 160,000-square-foot warehouse and a separate 11,680-square-foot fuel facility.
State filings listed March 2026 as the anticipated construction start and November 6, 2026 as the projected completion date. Construction is now underway.
But there's an important distinction:
November 2026 is a projected construction completion date—not a confirmed Costco opening date.
As of this update, Costco has not publicly announced an official opening date for the Grand Mason-area warehouse.
And here's another detail worth clearing up:
Cypress already has a Costco.
Costco's existing Cypress warehouse is located at 26960 NW Freeway and opened in 2019.
So the Grand Mason project is not "Cypress's first Costco."
It's an additional location serving another rapidly developing portion of the Cypress-area market.
That actually tells us something interesting about how much this part of Northwest Houston has grown.
Home Depot Is Planned Next
Costco isn't the only major retailer headed toward Grand Mason.
A new Home Depot is planned on the east side of Grand Parkway, south of the West Road intersection.
According to the Texas project filing reported by multiple outlets, the new store is planned at approximately 134,808 square feet, with an estimated construction cost of about $20 million.
The current filing lists:
Construction start: October 15, 2026Estimated completion: September 20, 2027
As of September 6, construction is therefore not scheduled to begin until next month.
And just like Costco:
Estimated completion doesn't equal an official opening date.
No official opening date for this Home Depot has been announced.
What Else Is Coming to Grand Mason?
This is where we need to be careful.
When a development this large starts circulating on social media, conceptual site plans can quickly turn into:
"Look at all these stores that are coming!"
That's not necessarily what a site plan means.
Updated Grand Mason materials show a much broader vision beyond Costco and Home Depot.
The preliminary Phase I plan includes areas contemplated for uses such as a medical office campus, hospital campus, lifestyle and entertainment center, fitness center, power-center retail, home-improvement-anchored retail, restaurants, services and additional commercial sites.
But here's the distinction I want homeowners to remember:
Confirmed or documented projects
Costco: Construction underway.
Home Depot: Documented in a state filing, with construction currently scheduled to begin in October 2026.
Part of the broader development vision
Additional retail, restaurants, entertainment, medical, office, hotel, residential and other uses appear in Grand Mason's broader plans.
NewQuest has not publicly released a complete construction schedule or definitive opening timeline for all of those components.
That's why I wouldn't treat every logo, building or use you see on a preliminary development plan as a guaranteed future business.
Planned doesn't mean open.
And a concept on a site plan doesn't always mean a lease has been signed.
Why Is So Much Commercial Development Coming to This Part of Cypress?
Here's where the story gets more interesting than Costco.
Retail follows people.
Or, as we often say in real estate:
Retail follows rooftops.
Grand Mason is surrounded by an area that has been adding homes and residents rapidly.
According to current reporting based on NewQuest's trade-area data, the population within a three-mile radius of the development increased by approximately 51% between 2020 and 2025.
Nearby master-planned communities and residential developments have put thousands of households into this broader corridor.
And those households need places to:
Shop.
Eat.
Work.
See a doctor.
Exercise.
Meet friends.
Run errands.
And spend money.
Major retailers don't choose locations randomly.
They study population, income, traffic, accessibility, competition, growth projections and surrounding development before committing millions of dollars to a location.
That doesn't guarantee every commercial project succeeds.
But it helps explain why we're seeing increasingly significant commercial investment along this part of Grand Parkway.
The Grand Parkway Is Becoming More Than a Commuter Road
This is one of the bigger changes I've watched across Northwest Houston.
For many homeowners, the Grand Parkway originally meant one thing:
Getting somewhere faster.
Tomball to Cypress.
Cypress to Katy.
Spring to Tomball.
And connections to other major highways.
But as residential development fills in around SH 99, the role of the Grand Parkway is changing.
Housing creates population.
Population creates demand.
Demand attracts retail, restaurants, medical services, offices and entertainment.
Eventually, a transportation corridor becomes a development corridor.
Grand Mason is one example of that evolution.
And we're seeing versions of the same story elsewhere across Northwest Houston—from Magnolia's proposed Town Center to major retail growth around SH 249.
What Could Grand Mason Mean for Cypress Homeowners?
This is usually where homeowners ask me:
"Is this good for my neighborhood?"
There's no one-size-fits-all answer.
A project like Grand Mason can change how residents experience the area in several ways.
1. More Everyday Convenience
For residents around the western Cypress and north Katy portions of Grand Parkway, additional shopping, restaurants and services could mean fewer long drives for everyday errands.
That's a real quality-of-life consideration.
If Grand Mason develops according to its broader vision, residents could eventually have access to much more than big-box shopping.
But again, many of those uses remain planned rather than completed.
2. More Traffic
More commercial development also means more vehicle trips.
Customers.
Employees.
Deliveries.
Residents.
Visitors.
Grand Mason's Grand Parkway location gives it significant regional accessibility, but homeowners should still pay attention to how surrounding roads, entrances, exits and intersections evolve as development continues.
We shouldn't assume exactly what future traffic conditions will look like before we have the data.
But we shouldn't pretend thousands of square feet of new commercial development have no traffic implications either.
3. A Changing Local Landscape
A family that bought nearby five years ago may have looked across undeveloped land.
Five years from now, that same drive could include major retailers, restaurants, offices or other development.
Neither is automatically better.
They're simply different environments.
4. Different Buyers Will See It Differently
One buyer might say:
"I love being ten minutes from Costco, restaurants and everything I need."
Another might say:
"I'd rather be farther away from commercial development."
That's why the effect on real estate isn't as simple as:
Costco = higher home prices.
Will Costco and Home Depot Increase Cypress Home Values?
I see versions of this question every time a major retailer is announced.
So let's address it directly.
A new Costco or Home Depot does not guarantee that nearby home values will increase.
Property values depend on a combination of factors, including:
Location
Neighborhood
School zoning
Property condition
Lot characteristics
Comparable sales
Housing inventory
Interest rates
Property taxes
Buyer demand
Nearby land uses
Commercial growth can influence convenience, buyer perception, traffic and the overall character of an area, but those effects aren't identical for every property.
My appraisal background makes me especially cautious about broad statements like:
"Costco is coming, so everyone's house is going up in value."
That's not how valuation works.
The better question is:
How does this development affect this particular property's location and how future buyers may perceive it?
That's a much more useful real estate conversation.
How Close Is Too Close to Major Retail?
This is something homebuyers don't always think about while touring new construction.
They hear:
"Only five minutes from shopping!"
That sounds great.
And sometimes it is.
But there's a meaningful difference between being conveniently close to commercial development and being immediately adjacent to it.
A buyer should look at things like:
Distance from major commercial sites
Road access
Potential traffic patterns
Lighting
Noise
Undeveloped land nearby
Future road connections
Current and proposed land uses
You may decide the convenience outweighs everything else.
Or you may prefer another section of the neighborhood.
The point isn't to tell you which answer is right.
It's to make sure you're asking the question before you buy.
Look at the map before you fall in love with the granite countertops.
What Does Grand Mason Mean for Bridgeland and Nearby Communities?
Grand Mason isn't inside every nearby community, of course, but its regional scale matters because the Grand Parkway connects multiple rapidly growing residential areas.
Communities such as Bridgeland, Elyson, Marvida and Mason Woods are part of the broader population base surrounding this corridor. Grand Mason's location also gives it access to residents traveling from other parts of Cypress and north Katy.
For homeowners, that can mean the amenity map around their neighborhood continues changing even after their home is built.
That's something buyers sometimes underestimate with new construction.
You're not only buying the house and community that exist today.
You're buying into an area that may still be developing around you.
Buying Near Grand Mason? Research More Than the House
If you're considering a home near Grand Mason—or anywhere in a rapidly growing part of Cypress—here are some things I'd investigate before making an offer.
What's there today?
Drive the surrounding roads.
Don't rely solely on the route the GPS gives you.
What's planned nearby?
Look at undeveloped parcels, commercial plans and future road connections.
How will you actually commute?
Test the drive when you would normally be traveling—not at 11 a.m. on a Tuesday because that's when you toured the model home.
How close do you want to be to retail?
Five minutes away might be perfect.
Immediately next door may feel very different.
What are the property taxes?
Two homes with similar prices can produce very different monthly housing costs depending on the taxing jurisdictions involved.
What HOA or MUD costs apply?
Understand the entire monthly and annual ownership picture.
What about flooding and drainage?
Research the specific property, not simply "Cypress."
What schools currently serve the property?
School boundaries can change as growing districts add campuses and adjust attendance zones. Always verify current zoning with the applicable school district.
These questions aren't as exciting as choosing countertops.
But they're often much more important five years after closing.
Cypress Isn't Just Adding Homes Anymore
For years, the Cypress growth story was largely about rooftops.
New neighborhoods.
New sections.
New master-planned communities.
New schools.
More families moving farther west and northwest.
But residential growth eventually creates demand for something else:
The commercial infrastructure to support all those households.
That's why I think Grand Mason is more interesting than the headline:
"Another Costco is coming."
The bigger story is:
Cypress is evolving from an area known primarily for residential growth into a corridor with increasingly significant retail, services, employment and commercial destinations.
Costco and Home Depot are visible evidence of that change.
Grand Mason shows us how much larger the next stage could be.
What's Actually Confirmed at Grand Mason Right Now?

Development Disclaimer: Plans, construction schedules, tenant lineups, opening dates and project scope can change. Conceptual or preliminary site plans should not be interpreted as guarantees that every depicted business or use will ultimately be built.
What Happens Next at Grand Mason?
Over the next year, there are several things worth watching.
The most immediate will be progress on the Costco construction and whether Costco announces an official opening date.
Home Depot's state filing currently calls for construction to begin in October 2026, so that will be another milestone to watch.
Beyond those two anchors, the bigger question is how quickly the rest of Grand Mason begins taking shape.
NewQuest's current vision is substantial, but a development of approximately 400 acres isn't built overnight.
Different phases can move at different speeds.
Plans can evolve.
Tenants can change.
Timelines can shift.
That's why you'll hear me use three different words when talking about developments like this:
Confirmed.
Planned.
Rumored.
Those are not the same thing.
And if I can't verify a rumored restaurant or retailer, I'm not going to tell a homebuyer it's coming just because somebody posted it in a Facebook group.
The Texas Home Coach Take
When I look at Grand Mason, I don't just see Costco and Home Depot.
I see another piece of the bigger Cypress story.
Homes came first.
Families followed.
And now more of the retail, services and commercial infrastructure are catching up with the population around them.
For homeowners, that can mean more convenience and a changing landscape.
For buyers, it reinforces something I say all the time:
Don't just buy the house. Understand what's happening around it.
As a Realtor, Mortgage Loan Officer, former appraiser and general contractor, I look at a property from more than one angle.
What's the house worth?
What will it cost to own?
What's being built nearby?
How might the area change?
What trade-offs are you making?
And does the whole picture fit your family's game plan?
Because a great house in the wrong location for you isn't necessarily a great purchase.

Is Grand Mason near Bridgeland?
Grand Mason is along Grand Parkway between FM 529 and West Road and is within the broader Cypress growth corridor that also serves residents traveling from Bridgeland and other nearby master-planned communities.
Will Grand Mason increase nearby home values?
There is no responsible way to guarantee that. Major commercial development can affect convenience, traffic, buyer perception and surrounding land uses, but individual home values depend on the property's location, condition, neighborhood, schools, comparable sales, taxes, inventory, demand and broader market conditions.
Should I buy a home near Grand Mason?
That depends on your priorities. Some buyers value quick access to shopping, restaurants and services, while others prefer more distance from major commercial areas. Before buying, evaluate the specific home's location, nearby land uses, road access, taxes, flood information, school zoning and future development—not simply its distance from Costco.
