Many, many years ago, my wife and I were in France for our honeymoon. During our travels I saw something that stopped me in my footsteps. I was standing in front of a structure that was hundreds of years old, and as I looked, my attention was drawn to one specific element: a dramatic, twenty-foot long support. Not only was it hand-carved and beautifully wrought in elegant detail, it was an integral part of the structural framing system.

The designers and craftsmen had created a beautiful structural element by layering simplicity: they had used only a few basic geometric patterns (namely circles and straight lines) and combined them using a limited set of operations (intersection, offsetting, and extrusions). The result was a breathtaking and amazingly detailed facade.

This marriage of beauty and function stayed with me, and my appreciation of tracery deepened as I researched it further. I discovered that as the complexity of tracery increased, so did the need for masons to draw out their designs in advance. This documentation step was necessary as both a way of experimenting with patterns and as a way of communicating those designs to customers and other craftsmen.

To get around the size limitations of parchment sheets, these designs would often be etched into a whitewashed board or a conveniently placed section of wall; in the latter case, the wall would be covered with a thin layer of plaster so the design would show more clearly. This, too, stayed with me, and much like the masons of old, I have a reputation with coworkers and friends for drawing design elements full scale on the sub-floor or a handy wall to think through all the details of a design before we build it.

Frequently Asked Questions

Before You Start

What to Expect from Tracery Builders

Why do so many people have home construction nightmares?

For most people, a major home construction project represents the largest purchase of their life after buying a home. Unfortunately, you can't approach a construction project like you would any other domestic purchase. First of all, significantly more money is involved and the process of handling/tracking those funds on the business side is significantly more complex (at Tracery Builders, we have a CPA on staff whose sole job is to track every job to the penny!). Secondly, you pay for most of it, sight unseen. Unlike a shirt or car, your construction project is built after you decide to purchase, not before. What's more, if you're building a custom home then it's likely a similar product has never been built before. In other industries, a new product means samples, models, prototypes, and debugging. In construction, your custom designed house is the prototype.

When you look closely at most construction nightmares, you will find these elements at the heart of the problem: in some cases, consumers may have been seduced by a low bid. In others the final result is crippled with construction defects, rushed workmanship, and poor durability of the installed items. And in still others, poor money management allowed costs and scheduling to spiral out of control; some contractors are good at building but poor at management control, financial document, and lien releases.

Avoiding construction nightmares requires a solid relationship between the builder and the customer and realistic expectations based on the Iron Triangle; the Iron Triangle is a concept used in construction to embody the three conflicting elements that go into a project: scope, budget, and time.


The triangle above represents the resources available for your project and the goal is to keep the triangle as balanced as possible. No project has infinite resources so making one corner of the triangle smaller or larger forces the other corners to shrink or grow to maintain the balance. For example, if keeping the budget small is the defining factor of a project, scope and time have to remain small to accommodate it while increasing the set of features or functionality (scope) in the project requires a larger budget and more time. You should keep the triangle in mind when making any decision that will affect the overall outcome of your project.

How do I select a custom home builder or remodeler?

Unfortunately, there is no foolproof way of making the right choice but it usually comes down to a good reputation, technical expertise, and finding someone you can work with comfortably.

back to top ^

Should I competitively bid my project to several builders or negotiate with one builder?

In theory, a competitive bid makes sense, but in reality the process is flawed. Very often bidding is based on a set of incomplete plans and the bids themselves are never a true apples-to-apples comparison. Each builder is calculating their costs based on the quality and service they intend to offer: some may bid low, counting on change requests mid-project to increase the final price while others bid sloppily and use poor workmanship or materials to avoid going over budget. The worst will scrutinize plans for errors and omissions that provide areas they can exploit to their advantage

At Tracery Builders, we recommend negotiating with a reputable, trustworthy builder that you have researched thoroughly. If you do decide to go with a competitive bid, we prefer to know who we are bidding against, to ensure we are competing with builders who provide a comparable level of quality and workmanship, and never bid with four or more participants.

back to top ^

How do I analyze competitive bids on home construction projects?

First, make sure the bids are as close to apples-to-apples as possible; every home builder has his own way of estimating and may use different categories than his competitors. To ensure the estimates are as consistent as possible, we suggest providing an outline specification (an Outline Spec) when the plans are given out to bid. Take note of things the builder has included in their estimate (inclusions) and things they are explicitly not including (exclusions). A simple, one line exclusion like providing scaffolding can cost thousands extra on larger jobs. The more information you can obtain about how the bid prices were calculated, and the clearer it's presented, the better chance you have of making the right decision.

All that being said, choosing a home builder should never be based on price alone. It's also important to consider the long-term durability of the construction and materials being used, the air quality when you move in, and the impact on you and your family during construction.
