Internal Rate of Return (IRR)
A metric for assessing profitability over time. IRR is the discount rate at which the net present value (NPV) of all future cash flows (positive and negative) from an investment equals zero — including both periodic cash flow (such as rent) and a projected sale at the end of the holding period. It represents the expected annualized return, accounting for income, expenses, and the recovery of capital through a future sale.
Property Description
Nestled along the illustrious coastline of Sea Island, this exceptional residence by the eminent architect John Portman is an embodiment of modernist philosophy and an exemplar of the 'Entelechy' concept-a state in which potentiality reaches its fullest realization. This residence transcends the conventional, standing as a harmonious interplay between architectural form and the natural grandeur of its oceanfront setting. Portman's genius is evident in the meticulous orchestration of space, light, and materiality. Expansive glass fa ades blur the demarcations between interior and exterior, inviting the serene panorama of the Atlantic Ocean into every room. The soaring volumes and fluid transitions between spaces evoke a sense of grandeur and openness, where each architectural element is conceived not just for its aesthetic merit but as part of a holistic experience. The residence captures the very essence of coastal modernism, where the ebb and flow of the ocean find their reflection in the dynamic forms and tranquil atmospheres within. The home's interiors are a study in sophistication and restraint, with a palette of materials selected to echo the natural surroundings while asserting a timeless, yet progressive, elegance. The interplay of light and shadow across the curated finishes creates an environment that is at once meditative and inspiring, embodying Portman's vision of architecture as a lived art form. This aesthetic is reminiscent of his work on Entelechy I and II, where the synergy between the built environment and its context elevates the residence from mere habitation to an immersive, sensory experience. Set against the pristine backdrop of Sea Island, the residence offers a rarefied living experience that is as much about embracing the natural splendor of the coastline as it is about dwelling within an architectural masterpiece. Here, the rhythmic sound of the waves and the ever-changing hues of the seascape become an integral part of the home's essence, enriching daily life with moments of quiet reflection and awe. In addition to the main residence, the property includes a private guest cottage featuring 4 bedrooms, 3.5 bathrooms, and 3,432 square feet. Not included in the main residence's bedroom count or square footage, this cottage serves as an ideal space for accommodating additional guests, offering privacy and comfort while preserving the residence's serene connection to the surrounding landscape. This is not merely a home; it is a sanctuary of enlightened living, where every design decision has been made with an eye toward creating a seamless dialogue between the structure and its surroundings. It stands as a testament to Portman's architectural legacy, a rare opportunity to reside in a space where the boundaries between art, architecture, and nature dissolve into a unified, transcendent experience.
