# Site Costs Properly Assessed Upfront

Every home starts with a block of land—but not every block costs the same to build on.
One of the most common reasons building costs increase after contract signing is because the site hasn't been fully understood before construction begins. Excavation requirements, cut and fill, retaining walls, drainage and other site-specific conditions can all have a significant impact on the final cost of a project.
Unfortunately, these costs are often underestimated, left as provisional allowances, or not fully investigated until construction is underway.
At DJ Homes, we believe there is a better way.
That's why assessing site costs is an important part of the DJ Difference.
Before contract signing, we take the time to understand the unique characteristics of your block. We calculate excavation requirements, determine how much cut and fill is required, assess retaining wall requirements and identify other site considerations that may affect construction.
This detailed assessment allows us to provide a price that more accurately reflects the true cost of your project.
It's not simply about avoiding surprises.
It's about helping our clients make informed decisions before they commit.
Sometimes that means adjusting the design slightly to reduce excavation. Sometimes it means incorporating a split-level design that works with the natural slope of the land rather than against it. Sometimes it confirms that additional retaining is required, allowing those costs to be planned for from the beginning rather than discovered later.
These conversations happen before construction starts—when changes are easy to make, not when they become expensive.
One example is sandstone retaining walls. At DJ Homes, these are considered during our preliminary process and included in our pricing where required, rather than becoming an unexpected variation later in the build.
It's another example of our philosophy of investing more time before contract signing so our clients experience fewer surprises during construction.
Building a home is one of the biggest investments you'll ever make.
We believe your builder should understand the site just as well as they understand the house.
Because confidence doesn't come from a low starting price.
It comes from knowing your contract reflects the home you're building—and the block you're building it on.
