If you’re wondering how a few thousand square feet turns into a few hundred thousand dollars, well, you’re in luck! In this section of advanced home design, I’ll walk you through a few of the ways in which your crude “working drawing” can reveal how expensive each room might be:
In as much as a butcher charges by the pound and a boutique salon sells perfume by the ounce, the construction industry runs on square footage. In short, every foot costs something, and many/most of the vendors and trade craftsmen bid by the square foot.
Most people only consider the square footage that is “under air.” That is, with a roof over it and living space treated by air conditioning. The construction industry has a variety of ways of measuring a square foot that includes under air and then some.
For instance, a “framer” charges by what is called “covered” square footage. That includes all living areas, the garage, the overhangs and the porches. As one might imagine, when charging by the foot, this can add up quickly. Additionally, you must consider the square footage of big porches and other outdoor living area. In fact, many homebuilders calculate the square footage of those areas when they tell you how big the home is. The same is true for garages. That is part of the calculation that must be included. Some Builders even calculate the interior cubic air footage. All that open space comes at some cost.
Another expense that can add up quickly is plumbing, which may seem like it only exists in the bathroom and under sinks, but in fact can snake through the entire house when you consider how water gets to your upstairs bathroom.
You wouldn’t imagine that cabinet space could drive up the cost of a home, but you’d be surprised. Depending on the type of cabinets you select, how many of them, upper and lower and what kind of finish, you’d be amazed by how much that affects the cost of your kitchen.
Every foot of cabinet goes up in cost depending on the finish, the model, the make or the quality of material involved. It seems like such a minor thing when you’re talking about floor tiles and an outdoor living room, but look to how many square feet of cabinets you’re planning on having and how that affects the bottom line kitchen cost.
This is why both the concierge form and the working drawing are so important when it comes to making compromises. Room by room, we can point to the hidden costs that drive up the final estimate and, in this way, they can be addressed instance by instance.
Obviously, this isn’t my first time at the rodeo, nor is it my sales team’s. So, as we discuss the concierge form with clients, we might point out that a certain finish of cabinet can get exorbitant, hard to find, etc. This can help avoid surprises later, but even then, it often takes the working drawing estimates to make those prices clear for home builders.
The more complex your home design, the more bells and whistles you include on your concierge form—Tuscan elevation, a lot of closet space, gourmet serving island, two dishwashers, built in cabinets, double stair cases, epoxy floor covering in the garage, etc.—the more expensive it is.
When we’re talking about walk in closets, man caves, arboretums and speakers in the garage, this probably shouldn’t come as a surprise, but it often does, and so I want to address that here momentarily.
The term most related to complexity in the construction industry is Aspect Ratio. Simply put, a low aspect ratio home is a less expensive home, while a high aspect ratio home costs more. For instance, your typical suburban square or rectangular home, which from the air might look like a gift box or shoebox shaped home, has a low aspect ratio. Why? Because it’s simply less complex than other styles of home.
Now, compare that box-shaped, low-aspect ratio home with one that is wrapped around a swimming pool in a central courtyard, with cupolas coming out of the roof and multiple exits and levels, and the aspect ratio goes higher and higher with each design flourish.
So, while the more complex home is beautiful, it should come as no surprise that, with such complexity, comes a higher price tag.
It’s great to sit on your covered, screened-in porch at the end of a long day and kick back with a refreshing drink and the joy of custom home ownership. And while covered porches aren’t as expensive as, say, an air-conditioned and interior room, they’re more expensive than most home buyers realize.
The fancy flourishes that clients love to decorate their interiors with, such as trim, crown molding, tiled ceilings or inlaid tile walls and faux panting, those interior finishes add up. Room by room, square foot by square foot, we provide a variety of options if this is where home builders want to eventually compromise.
