The hidden economics of luxury real estate and the case for building your own.
There is a curious phenomenon in the upper reaches of the California residential real estate market. A substantial estate is listed for $56 million, sits on the market for a year or two, and eventually sees its asking price reduced to $28 million. To a prospective buyer, particularly one who appreciates the opportunity to acquire distressed assets, the reduction can appear extraordinary. Here is a property that was once offered for twice the price, now available at what looks like a remarkable discount.
But was the house ever worth $56 million? And is $28 million necessarily a bargain?
In the ultra-luxury market, asking prices can be remarkably aspirational. Unlike more conventional residential properties, where comparable sales provide a relatively reliable basis for valuation, exceptional estates are often difficult to compare. Their scale, location, amenities, and architectural character may be unique, and the pool of potential buyers is small. A seller can afford to wait, sometimes for years, hoping to encounter a buyer with both the means and the particular desire to acquire the property at an ambitious price.
There is a well-established psychological phenomenon called anchoring, in which an initial number becomes the reference point against which subsequent numbers are judged. Once a house has been offered at $56 million, $28 million can feel like a tremendous opportunity. But the original asking price tells us little about the property's actual value. The reduction may simply represent a seller gradually discovering what the market is willing to bear.
The more consequential question is what the buyer is actually getting for $28 million.
Luxury on the Surface
One of the more surprising realities of high-end residential construction is how little the underlying building may differ from a far less expensive house. Particularly in older homes and those built speculatively, the framing, waterproofing, drainage, and mechanical infrastructure may be remarkably ordinary. The distinction is often found in the finishes: expensive stone, elaborate millwork, sophisticated lighting, and fixtures selected to communicate luxury. These elements can be beautiful, but they tell us surprisingly little about the quality of the building beneath them.
I've spent enough time opening up expensive California homes to know how frequently the apparent quality of a house ends at the surface. Behind beautifully finished walls we've encountered rot, mold, inadequate structure, failed waterproofing, and evidence of chronic water intrusion. Some of these conditions developed through years of deferred maintenance; others were the consequence of decisions made when the house was originally built. In either case, the cost of correcting them can be extraordinary, particularly when doing so requires dismantling and reconstructing finishes that were themselves expensive.
The problem is compounded by the limits of what can reasonably be discovered before purchasing a property. A conventional home inspection may identify visible deterioration, aging equipment, or signs of moisture intrusion, but it cannot reliably establish the condition of concealed framing, waterproofing assemblies, buried drainage systems, or foundations. Even a sophisticated buyer employing engineers and specialty consultants may be unable to investigate these conditions without opening walls, removing finishes, or excavating portions of the site. Such investigations are not always practical, or permitted, before a transaction closes.
This is an important distinction. The problem isn't simply that the buyer failed to negotiate a sufficiently low price. It's that some of the most expensive liabilities associated with the property may be impossible to quantify at the time of purchase.
And the finishes that make the house appear so desirable can be the very things concealing its deficiencies.
What Makes a House Well Built?
Age alone is not a reliable measure of construction quality. Some California houses built more than a century ago were framed and sheathed in old-growth redwood, with hot-mopped asphalt waterproofing applied to their exterior walls. We've encountered these assemblies still performing remarkably well more than a hundred years later, demonstrating a level of durability and material integrity that would be costly to reproduce today.
Conversely, a newly constructed custom home may rely on conventional framing, OSB sheathing, and stapled-on housewrap beneath an extravagant collection of finishes. None of these materials is inherently deficient, but neither the age of a building nor the expense of its finishes tells us whether its underlying construction was thoughtfully designed and properly executed.
The distinction emerges when a skilled architect and an equally capable contractor are engaged to consider the building as a complete system. A genuinely high-quality home begins with its foundations, structure, drainage, waterproofing, and mechanical infrastructure, long before anyone selects a slab of marble. These elements determine whether the building will remain dry, comfortable, durable, and relatively trouble-free over time. They require thoughtful detailing, careful coordination, competent execution, and an investment in quality that may be largely invisible once construction is complete.
At a construction cost of $2,000 per square foot, a client should reasonably expect this level of care. Yet the purchase price of an existing luxury home provides no assurance that it was ever delivered.
The Economics of an Apparent Bargain
Consider a hypothetical 14,000-square-foot estate purchased for $28 million, or $2,000 per square foot. The house is substantial, the grounds are impressive, and the interiors, while somewhat dated, appear luxurious. Compared with its original $56 million asking price, the acquisition seems almost irresistible.
Then the renovation begins.
The roof needs replacement. Site drainage is inadequate, and water has been finding its way into portions of the building for years. Concealed framing has deteriorated. The electrical distribution is obsolete, the mechanical systems are approaching the end of their useful lives, and portions of the foundation require remediation. The landscape, terraces, and retaining walls need extensive work. Once the walls are opened, additional conditions emerge that were not apparent during the purchase process.
Meanwhile, the buyer wants to update the kitchens and bathrooms, improve the relationship between principal rooms, replace windows and doors, and bring the interiors into alignment with contemporary expectations. The original scope grows as the distinction between necessary repairs and desired improvements becomes increasingly difficult to maintain.
What began as a seemingly attractive acquisition becomes a $12 million renovation. The buyer now has $40 million invested in a house that was purchased for $28 million, bringing the combined cost to approximately $2,850 per square foot, including the land.
And what has that additional $12 million purchased?
Some of it has undoubtedly improved the house. But a substantial portion may have been spent replacing failed systems, correcting concealed deficiencies, and reconstructing portions of a building that should have been sound in the first place. These expenditures are necessary, often technically demanding, and sometimes remarkably expensive, yet they may contribute very little to the visible or experiential quality of the completed home.
The buyer has spent millions simply getting back to zero.
There are also costs that rarely appear in the initial calculation: design and engineering fees, temporary housing, financing and carrying costs, unforeseen conditions, construction delays, and the considerable time required to make decisions about an existing building whose limitations become apparent only gradually.
At this point, the economics of the original bargain deserve another look.
What Could You Build Instead?
Suppose the same buyer approached the decision differently. Rather than purchasing a $28 million estate and spending another $12 million correcting and adapting it, what might be possible with a total investment of $40 million directed toward land and new construction?
The answer depends heavily on location. In certain California markets, the land alone can command an extraordinary premium, and an existing property may offer entitlements, mature landscaping, or a building footprint that would be difficult to reproduce under current regulations. These are legitimate considerations, and there are circumstances in which acquiring and renovating an existing house is unquestionably the better choice.
But the comparison deserves to be made before the purchase, rather than after the renovation has begun.
Imagine acquiring a suitable property for $12 million and directing the remaining $28 million toward the design and construction of a new 14,000-square-foot home. At an all-in project allowance equivalent to $2,000 per square foot, the budget would need to account for construction, professional services, site development, contingencies, and other project costs. Depending on the property and the complexity of the program, that may or may not be sufficient. But it establishes a useful basis for evaluating the alternatives.
More importantly, the buyer would be investing in a building whose underlying construction could be conceived, detailed, and executed to an entirely different standard.
Contemporary building technology offers extraordinary opportunities for durability and performance. Continuous liquid-applied waterproofing, carefully integrated drainage systems, high-performance building envelopes, thoughtfully engineered structures, and sophisticated mechanical systems can be coordinated from the outset. With appropriate detailing, qualified contractors, rigorous quality assurance, and careful execution, the risk of many common building failures can be almost entirely elimiated.
A new home is not immune to defects, and even the best buildings require maintenance. But there is an enormous difference between designing a complete building system with performance as a primary objective and attempting to correct decades of accumulated problems within an existing structure.
At this level of investment, the client can reasonably insist that the quality of the construction extend far beyond what is visible.
The Cost of Someone Else's Decisions
There is another consideration that becomes increasingly important as the cost of renovation approaches that of new construction.
Even after a comprehensive renovation, the buyer is still working within the fundamental organization of a house designed for someone else. The structure, floor levels, circulation, proportions, and relationship to the site may impose constraints that are difficult or prohibitively expensive to change. A room can be beautifully refinished without becoming a particularly good room. A house can be thoroughly modernized while retaining awkward circulation, compromised daylight, or an uninspired relationship to its landscape.
These are not necessarily defects. They are simply the architectural decisions, preferences, and compromises inherited from the previous owner.
For a family prepared to invest tens of millions of dollars in a home, this raises an interesting question: why accept those compromises if the cost of building something entirely new may be comparable?
Commissioning a home offers the opportunity to begin with the way a family actually wants to live. Perhaps that includes a remarkable library, a workshop, a music room with exceptional acoustics, an art gallery, or a garage designed around a serious automobile collection. Perhaps the house is organized around a series of gardens and courtyards, with unexpected daylight, layered spaces, and carefully considered relationships between indoors and outdoors.
Or perhaps, as my assistant once suggested, the client wants a leather-lined Batcave.
Why not?
The point is that the possibilities are no longer limited to what happens to be available on the market. The home can become a highly personal expression of the people who commission it, shaped around their interests, rituals, collections, and aspirations. And unlike a renovation, these ambitions can inform the architecture from its earliest conception rather than being accommodated within an inherited framework.
This opportunity has value, even if it cannot be reduced to a price per square foot.
A Different Way to Evaluate Value
None of this suggests that every existing luxury home is a poor investment, or that building new is invariably more economical. Some properties possess extraordinary architectural quality, exceptional construction, or irreplaceable relationships to their sites. Others offer historic character and craftsmanship that would be difficult to achieve today. A well-informed buyer may quite reasonably conclude that such qualities justify the expense of restoration or renovation.
But buyers should be cautious about confusing a dramatic reduction in asking price with an opportunity to acquire genuine value. Particularly in the upper reaches of the market, the original price may have been little more than an aspiration, and the apparent discount may conceal substantial obligations that cannot be fully understood before construction begins.
The more useful comparison is between the total cost of acquiring and adapting an existing house and the total cost of commissioning a new one. That calculation should include the condition of the underlying construction, the cost of correcting deficiencies, the limitations of the existing architecture, and the quality of the completed result.
For families with the resources to pursue either path, the question is worth considering before becoming attached to a particular property.
A $28 million house reduced from $56 million may indeed be an extraordinary opportunity. It may also be a $40 million project waiting to happen, with years of work required to arrive at a result that remains less than ideal.
At that point, I would want to know what else $40 million could make possible.
