A Stefan Antoni Triplex Penthouse with Exceptional Hospitality Potential - Positioned along Mouille Point's Atlantic Seaboard, Stairway to Heaven is a distinctive luxury triplex penthouse combining panoramic ocean views, a private rooftop garden and an extensive collection of resort-style amenities.

The residence is described as the only Stefan Antoni-designed triplex penthouse on Mouille Point's Platinum Mile. It offers five en-suite bedrooms, six bathrooms and a guest toilet, with a glass elevator connecting all three levels. 

Its defining feature is the substantial rooftop environment, incorporating a full-size heated swimming pool, jacuzzi pool, two sea-facing patios and an outdoor shower. Inside, formal and informal lounges, dining areas, a study, playroom, poolroom and bar create a layout suited to both private occupation and large-group entertaining.

Air-conditioning, underfloor heating, multiple fireplaces, three kitchen areas, integrated audiovisual systems and extensive security features reinforce its premium positioning. Residents also benefit from the building's reported concierge, gym, sauna, communal pool and other shared amenities.

The investment proposition extends beyond conventional apartment ownership.

Stairway to Heaven combines a potentially scarce residential asset with the opportunity to generate luxury holiday rental income, while retaining the possibility of personal vacation use.

If architectural provenance, ocean views and hospitality potential converge in one penthouse — what would you be prepared to invest to secure it?

Estimated Market Value — 2026

Indicative Investment-Market Positioning: R35 Million – R55 Million

KeyPrice Indicative Midpoint: R45 Million

This is a provisional editorial estimate, not a formal valuation or a confirmed selling price. The source markets Stairway to Heaven as premium holiday accommodation and does not provide a verified current sale price or sufficient property-specific information to establish its market value independently.

The estimate considers the reported Stefan Antoni architectural authorship, triplex configuration, five en-suite bedrooms, rooftop garden and heated pool, panoramic sea views, glass elevator and premium building amenities.

Mouille Point's established coastal location provides an additional source of appeal. A comparable three-bedroom Waterclub penthouse was advertised at approximately R40 million in September 2026, while other high-end Mouille Point apartments have been marketed at prices approaching R50 million. These are asking prices for different properties, not direct evidence of Stairway to Heaven's value. 

The proposed range reflects the possibility of a substantial premium for a large, architect-designed penthouse with extensive private outdoor facilities. Its ultimate position would depend on verified internal floor area, exclusive-use rooftop rights, sectional-title documentation, levies, condition, parking allocation and comparable transactions.

The investment case must also account for the fact that this is an apartment within a larger building, rather than a freestanding property. Building rules, rental permissions and shared operating costs may materially affect its investment value.

Luxury Rental Performance

Advertised summer rates ranging from R42,000 to R100,000 per night in different sections of the page. This inconsistency means the current tariff should be confirmed directly with the property manager before building an investment forecast. 

The penthouse's five en-suite bedrooms, private rooftop pool, sea-facing patios and extensive entertainment spaces position it for premium family holidays, executive stays and luxury group accommodation.

Investment Appeal Scenarios

The following scenarios illustrate potential gross accommodation revenue at different achieved average nightly rates and occupancy levels. They are illustrative assumptions, not verified booking performance.

These calculations assume 365 available nights annually. They exclude management fees, booking commissions, staffing, utilities, maintenance, insurance, levies, rates and taxes.

Personal vacation use would also reduce the number of nights available for paying guests. Actual performance would depend on seasonal demand, achieved rates, rental permissions, minimum-stay requirements and the property's management arrangements.

At the R45 million indicative midpoint, the balanced scenario implies a theoretical gross rental yield of approximately 27.4%. This is not a net return forecast and should not be interpreted as evidence of achievable investment performance.

Why Investors May Consider Stairway to Heaven

The property's investment proposition rests on several characteristics:

• Architectural provenance: The reported Stefan Antoni design provides a distinctive point of differentiation.
• Coastal location: Mouille Point offers ocean-facing living along Cape Town's established Atlantic Seaboard.
• Private amenities: The rooftop pool, jacuzzi, patios and extensive entertainment spaces strengthen its holiday appeal.
• Premium accommodation: Five en-suite bedrooms support high-end group and family travel.
• Lifestyle flexibility: The property may offer a combination of personal vacation use and rental income, subject to building rules and operating arrangements.

The critical distinction is that a high advertised nightly rate does not establish sustainable annual income. Verified occupancy, actual booking receipts and operating costs are necessary to determine the property's investment performance.

KeyPrice Investment+ View

Stairway to Heaven presents a distinctive combination of architectural authorship, ocean views, private rooftop amenities and premium hospitality potential.

Its triplex layout and extensive leisure facilities create a proposition that differs from conventional Mouille Point apartments. For an owner seeking both a luxury vacation residence and a potential income-producing asset, this combination may offer meaningful lifestyle flexibility.

The investment thesis is therefore:

Architectural distinction + coastal real estate + hospitality income potential + personal-use value.

The proposed KeyPrice range of R35 million–R55 million, with an indicative midpoint of R45 million, remains provisional until the property's floor area, ownership documentation, rental permissions and comparable sales are verified.

The opportunity ultimately depends on the acquisition price and the balance between rental income, operating expenses, personal use and long-term resale value.
