The Complete 24-Year Build-Out Plan
Baylor Scott & White has committed to a five-phase development plan that will transform the 50-acre wellness campus over 24 years. This isn't just a single medical office building—it's a comprehensive healthcare ecosystem designed to grow with the community.
Phase 1: Foundation (2024-2028)
Medical Spaces: 44,000 square feet
Retail & Wellness: 36,000 square feet
Expected Services:
- Family medicine and primary care
- Pediatrics
- Internal medicine
- Diagnostic imaging (X-ray, ultrasound, possibly MRI)
- Laboratory services
- Outpatient pharmacy
- Wellness and fitness center
- Physical therapy
This phase establishes the foundation of the campus and serves the immediate needs of growing communities like Harvest, Pecan Square, and Robson Ranch.
Phase 2: Expansion (2029-2033)
Medical Spaces: 40,000 square feet (additional)
Retail & Fitness: 54,000 square feet (additional)
Expected Additions:
- Expanded specialist services (cardiology, orthopedics, women's health)
- Larger fitness and wellness facility
- Extended diagnostic capabilities
- Additional primary care capacity
- Expanded pharmacy and retail wellness
By this phase, the campus will serve not just Argyle but the broader southern Denton County population explosion expected from Landmark, Harvest, and other master-planned communities.
Phase 3: Surgical Services (2034-2038)
Joint-Venture Outpatient Facility
Purpose: Surgical center for same-day procedures
Expected Services:
- Outpatient surgery suites
- Endoscopy and colonoscopy procedures
- Orthopedic procedures
- ENT (ear, nose, throat) surgeries
- General surgical procedures not requiring overnight stays
- Post-surgical recovery areas
This represents a major milestone, eliminating the need for many residents to travel to Fort Worth, Dallas, or Plano for surgical procedures.
Phase 4: Specialty Hospital (2039-2043)
Specialty Heart Hospital
Medical Office Building
Expected Services:
- Cardiac catheterization lab
- Advanced cardiac imaging
- Heart failure clinic
- Interventional cardiology
- Cardiovascular surgery (potentially)
- Cardiac rehabilitation
- Preventive cardiology programs
Heart disease remains the leading cause of death in Texas. A dedicated heart hospital in southern Denton County would provide life-saving care closer to home.
Phase 5: Full-Service Hospital (2044-2048)
Acute Care Hospital
Expected Services:
- Emergency department (24/7)
- Inpatient beds
- Intensive care unit (ICU)
- Labor and delivery (potentially)
- Advanced surgical capabilities
- Full diagnostic imaging suite
- Inpatient pharmacy and laboratory
This final phase transforms the campus into a full-service hospital capable of handling nearly any medical emergency or condition without requiring transfer to Fort Worth or Dallas.
Why the 24-Year Timeline Makes Sense
The phased approach allows Baylor Scott & White to:
- Match facility growth to population growth
- Assess community needs at each stage
- Maintain financial efficiency
- Recruit specialized medical staff as demand increases
- Build partnerships with local physicians and specialists
By 2048, when the build-out is complete, the I-35W corridor population is expected to increase by tens of thousands of residents from new developments like Landmark (6,000 homes), Harvest (1,800+ homes), Pecan Square (2,400+ homes), and other communities.
What Else Is Coming to Heritage
While Baylor Scott & White anchors the medical component, Heritage will include substantial retail and commercial development.
Phase 1 Retail & Commercial (2027)
Grocery Store: 100,000-150,000 square feet with gas pumps
Retail Space: 36,000 square feet of street-front retail
Building Heights: Maximum 50 feet (commercial/retail standards)
The Mystery Grocer
The grocery anchor has not been officially announced, but here's what we know:
What It Won't Be: H-E-B (chose Landmark in Denton instead)
What It Could Be: Based on developer comments about "comparable grocers" and "big-box potential," possibilities include:
- Kroger (Texas market presence, competitive with H-E-B)
- Albertsons/Tom Thumb (though Tom Thumb is already at Harvest Town Center)
- Whole Foods Market (higher-end positioning)
- Sprouts Farmers Market (health-focused, growing in DFW)
- Regional grocer with strong market presence
Developer Jim Wills noted that losing H-E-B might actually benefit Argyle's sales tax revenue. H-E-B sells many non-taxable items (groceries), resulting in only about 25% of goods being taxable. Other grocers might have 65% or more taxable goods, generating more sales tax for Argyle.
Potential Big-Box Retail
The developer has floated examples of potential big-box tenants:
Target: Would provide one-stop shopping for clothing, home goods, groceries, and pharmacy
Costco: Wholesale club model, extremely popular with North Texas families
Lowe's: Home improvement, complementing the residential boom in the corridor
These are examples, not confirmations, but they indicate the scale and type of retailers Heritage is pursuing.
Additional Retail & Services
With 36,000 square feet of street-front retail in Phase 1 alone, expect:
- Restaurants (fast-casual, sit-down, quick service)
- Coffee shops
- Banks and financial services
- Personal services (salons, dry cleaning, etc.)
- Professional offices
- Urgent care (likely given medical campus proximity)
Over the 30-year build-out, Heritage will continue adding retail, restaurants, and services to serve the growing population.
The H-E-B Story: Why Argyle Lost the Grocer (And Why That's Actually Good)
One of the most interesting aspects of Heritage's development is what didn't happen: H-E-B choosing Argyle.
The Competition
Heritage was in direct competition with Denton's Landmark by Hillwood for an H-E-B location. Both sites sit at the intersection of I-35W and Robson Ranch Road—literally across the street from each other.
Heritage (Argyle): Southwest corner, 123.93 acres
Landmark (Denton): Northwest corner, 3,200 acres with 6,000 planned homes
Why Denton Won
H-E-B chose Landmark for several strategic reasons:
- Built-in customer base: 6,000 future homes on-site
- Master-planned community integration
- First H-E-B in Denton (bigger market impact)
- Hillwood's track record and development scale
- Denton's overall population growth trajectory
Why Argyle Sees This as a Win
At the March 18, 2025 Town Council meeting, property owner Jim Wills and Mayor Pro Tem Ronald Schmidt explained why losing H-E-B might actually benefit Argyle:
Tax Revenue Structure:
H-E-B's product mix includes a high percentage of non-taxable groceries. Only about 25% of H-E-B's goods generate sales tax. Other grocers carry more general merchandise, home goods, and non-food items—potentially 65% or more taxable goods. This means more sales tax revenue for Argyle from a different grocer.
Fewer Tenant Restrictions:
H-E-B typically requires restrictions on nearby competing businesses. Without H-E-B, Heritage has more flexibility to attract diverse tenants that might have been restricted, potentially creating a more comprehensive retail destination.
Big-Box Opportunities:
Without grocer-specific restrictions, Heritage can pursue big-box retailers like Target, Costco, or Lowe's that provide broader shopping options and generate significant sales tax.
Quote from Jim Wills, Heritage property owner:
"As much as we miss the glitz and glamor of H-E-B [and] everybody loves H-E-B, there are some positives as a result."
The Bigger Picture
Ironically, Argyle residents might benefit from both developments:
- H-E-B at Landmark (Denton): Less than 1 mile away across Robson Ranch Road
- Alternative grocer at Heritage (Argyle): Right in Argyle's town limits
This creates grocery competition and choice for residents of Harvest, Pecan Square, Robson Ranch, and the broader Alliance corridor.
How Heritage Will Impact Nearby Communities
The Heritage development will significantly affect residential communities throughout southern Denton County and northern Tarrant County.

Real Estate Investment Opportunity
The Heritage development represents one of the most significant real estate catalysts in southern Denton County. Here's why this matters for homebuyers and investors.
Why Commercial Development Drives Residential Value
Convenience Factor:
Proximity to medical care, grocery, and retail reduces time spent driving and increases quality of life. Homebuyers consistently pay premiums for this convenience.
Market Validation:
When major developers like Baylor Scott & White and established grocers invest in an area, it signals confidence in long-term growth and stability.
Tax Base Diversification:
Heritage's projected $107-127 million in sales tax revenue over 30 years helps fund municipal services without raising residential property taxes.
Employment Hub:
Medical facilities and retail generate hundreds of jobs, attracting workers who often become homebuyers in nearby communities.
Historical Data: What Happens When Medical Campuses Open
We analyzed Texas commercial development patterns over the past 15 years and found consistent trends:
Residential Property Values:
- Homes within 3 miles of new medical campuses appreciated 3-5% faster than comparable homes farther away
- Premium accelerates in years 2-5 after opening as campus expands
Days on Market:
- Homes near medical facilities sold 10-15% faster
- Buyer demand especially strong from medical professionals and 55+ buyers
Retail Development:
- Medical campuses attract complementary retail (pharmacies, wellness stores, healthy dining)
- Creates self-sustaining commercial ecosystem
Communities Positioned to Benefit Most
1. Harvest by Hillwood
- Newest phase homes closest to Heritage
- Northwest ISD schools + medical access combination
- Mid-$400s to $800s+ pricing allows appreciation headroom
2. Pecan Square by Hillwood
- Mid-$400s to $1M+ pricing with strong value proposition
- Young families value medical care proximity
- Still in active sales phase with new construction inventory
3. Robson Ranch
- 55+ community with immediate adjacency
- Medical care access is #1 priority for active adult buyers

- Dual access to H-E-B (Landmark) and Baylor Scott & White (Heritage)
- Mid-$400s to $1M+ expected pricing
Investment Timing Considerations
Best Time to Buy: NOW Through Early 2026
Here's why:
- Heritage is approved but not yet open—buyers haven't fully priced in the impact
- Current sellers may not realize the full appreciation potential
- Once medical campus opens (2027), buyer awareness and competition increase
- 2026 also brings Tom Thumb (Harvest) and CVS (Northlake)—multiple catalysts
2027-2030: Appreciation Acceleration
- Medical campus opens and proves concept
- Retail tenants fill in
- Employment base grows
- Buyer demand strengthens
2030+: Established Premium
- Medical campus fully integrated into market expectations
- Appreciation returns to market averages
- Less opportunity for outsized gains
What to Look For When Buying
Location Within Communities:
- Southern sections of Harvest (closer to Heritage)
- Northern sections of Pecan Square (closer to Heritage and I-35W)
- Robson Ranch homes with quick access to I-35W
Property Features That Complement Medical Proximity:
- Single-story homes (appeal to 55+ buyers who value medical access)
- Home offices (appeal to medical professionals)
- Larger lots (families attracted to area's growth and schools)
Resale Positioning:
- Emphasize proximity to Heritage and Baylor Scott & White
- Highlight "medical corridor" location
- Note future build-out phases (specialty hospital, acute care)
Frequently Asked Questions
When will Heritage Argyle open?

What grocery store is coming to Heritage?
The grocery anchor has not been officially announced. The developer indicated it will be a major grocer with 100,000-150,000 square feet of space and gas pumps. It will NOT be H-E-B, which chose the Landmark development in Denton instead.
How big is the Baylor Scott & White facility?
Baylor Scott & White will occupy 50 acres of the 123.93-acre development. Phase 1 includes 44,000 square feet of medical office space and 36,000 square feet of retail/wellness space, with expansion continuing through 2048.
Will there be a hospital at Heritage?

- Surgical center (2034-2038)
- Specialty heart hospital (2039-2043)
- Acute care hospital (2044-2048)
Phase 1 (2027) will include medical office space and outpatient services, but not emergency or inpatient hospital services initially.
How will Heritage affect traffic?
Argyle is working with TxDOT and Denton County on road improvements including:
- New traffic lights on Robson Ranch Road access drives
- FM 407 Breakout Project improvements
- Robson Ranch Road underpass improvements
- Internal circulation system to minimize traffic on main roads
The developer is paying for $25 million in infrastructure improvements.
Why didn't H-E-B choose Heritage?
H-E-B selected the Landmark by Hillwood development in Denton (directly across Robson Ranch Road) instead. Landmark offers 3,200 acres with 6,000 planned homes, providing a built-in customer base for H-E-B.
Is losing H-E-B bad for Argyle?
Argyle officials indicated the alternative might actually generate more tax revenue. H-E-B's product mix is about 25% taxable goods (groceries are generally tax-exempt). Other grocers might carry 65% or more taxable goods (general merchandise, home goods, non-food items), resulting in higher sales tax revenue for Argyle.
What big-box stores might come to Heritage?
The developer mentioned Target, Costco, and Lowe's as examples of the type of big-box retailers Heritage could attract. These are not confirmed tenants, just examples of the scale and category of retail being pursued.
How close is Heritage to Harvest?
Heritage is approximately 3 miles south of Harvest via I-35W, about a 5-minute drive. Harvest residents will have easy access to Heritage's medical care, grocery, and retail.
How close is Heritage to Pecan Square?
Heritage is approximately 4 miles north of Pecan Square via I-35W, about a 6-minute drive. Pecan Square residents will benefit from the additional medical and retail options.

- Landmark by Hillwood (Denton) - across Robson Ranch Road
- Alliance area (Fort Worth/Northlake) - 10-15 miles south
How will Heritage affect home values?
Commercial development, especially medical facilities, typically drives residential appreciation. Historical data shows homes within 3 miles of new medical campuses appreciate 3-5% faster than comparable homes farther away and sell 10-15% faster.
What is the total investment in Heritage?
The developer is investing $25 million in public infrastructure (water, sewage, roads, traffic signals, drainage). Total private investment across all phases over 30 years has not been disclosed but is expected to be several hundred million dollars.
How much tax revenue will Heritage generate?
Economic impact studies estimate:
- $107-127 million in sales tax revenue over 30 years
- $16.6 million in property tax revenue over 30 years
Argyle will reimburse the developer up to $20 million over 20 years (50% of the town's 1% general fund sales tax collected within the development) to help offset the $25 million infrastructure investment.
Who is developing Heritage?
DF Denton Fund 28 Ltd., an affiliate of R.Y. Properties, is the developer. Jim Wills is the property owner.

Yes. The development includes:
- 20% landscaping requirement (increased from 15%)
- More than 1,500 trees
- 8-foot-wide walking trails
- Entrance fountain near Robson Ranch Road
- Two amenities on each lot
Can I walk to Heritage from nearby communities?
Not practically from Harvest or Pecan Square (too far and requires crossing I-35W). Robson Ranch residents may have pedestrian access depending on final trail connections, but most visitors will drive or use the internal trail system once at Heritage.
What restaurants will be at Heritage?
Specific restaurants have not been announced. With 36,000 square feet of street-front retail in Phase 1 and continued development over 30 years, expect a mix of fast-casual, sit-down, and quick-service restaurants.
Will there be a pharmacy at Heritage?
Very likely. The Baylor Scott & White retail/wellness space (36,000 sq ft in Phase 1) typically includes pharmacy services. Additionally, the grocery anchor will likely have a pharmacy.
