Ten Rittenhouse Condos

130 S. 18th Street
Rittenhouse Square Philadelphia

Ten Rittenhouse, located at 130 South 18th Street in the Rittenhouse Square neighborhood within Center City Philadelphia, is one of the city’s most established luxury condominium buildings. Completed around 2009, the building offers approximately 160 residences ranging from spacious one-bedrooms to full-floor and penthouse units.

Its location—just off the Square—remains one of the most consistently sought-after positions in the Philadelphia condo market.

What You’re Really Getting at Ten Rittenhouse

Residences here are fundamentally different from typical Center City condos:

• Larger floor plans, often 2,000–5,000+ square feet
• High ceilings and oversized windows
• Premium kitchens (Sub-Zero, Miele)
• Marble baths and custom finishes
• Select units with terraces and direct elevator access

Building services include:

• 24-hour concierge and doorman
• valet parking
• indoor pool, spa, and fitness center
• resident lounge and private outdoor space

This is a true full-service, white-glove building, not just a condo with amenities.

Who This Building Works For

Ten Rittenhouse typically attracts buyers who:

• Are downsizing but not downsizing in lifestyle
• Want a luxury condo near Rittenhouse Square with service
• Value privacy over density
• Prefer established buildings over newer glass towers

This is a narrow, high-end buyer pool—and that matters for resale.

Questions We Get From Our Buyers

Most serious buyers ask about:

• Higher monthly condo fees
• Building Finances
• Comparison to newer ultra-luxury buildings

Those concerns are valid—and they can directly influence pricing and liquidity.

How Ten Rittenhouse Compares

At this level, buyers are typically deciding between:

• Ten Rittenhouse (established, service-driven luxury)
• Newer luxury towers (more modern, often higher pricing)
• Boutique buildings (fewer amenities, lower fees)

The trade-off is consistent:

Space, service, and location vs. newer design or lower carrying costs.

Market Insight: What’s Actually Happening

The broader Rittenhouse Square condo market has shifted over the past year:

• Median sale price: ~$581,000 (down ~22.8% year-over-year)
• Price per square foot: ~$493 (up ~12.9% year-over-year)
• Average sale-to-list ratio: ~95%
• Days on market: ~98–108 days

What this means 

• Prices have softened at the mid-market level
• But the price per square foot is holding or rising
• Luxury units are trading selectively—not broadly

That last point is key for a building like Ten Rittenhouse.

Bottom Line

If your priority is space, service, and a premier Rittenhouse Square location, Ten Rittenhouse remains one of the most established luxury options in Center City.

This is not a building where “average pricing” applies—each unit trades on its own merits.

Our Take

Ten Rittenhouse is a newer, yet established residence on the square. The square footage designated for amenities is beyond that of almost any other building of its size and age. The wide variety of floor plans is also unique. An upgraded, high-floor, square-facing home will command attention regardless of market conditions. Those attributes don’t go unnoticed.
