When you are at the beginning stages of planning and budgeting for your new home, landscape and hardscape design and construction budgets are almost always under-funded.
Builders will often allocate minimal amounts for a front landscape in their overall construction cost. Their reasoning behind this is they don’t know exactly what you desire but feel they should allocate at least a small allowance. This is usually enough to do some small foundational planting in the front of the home and a concrete sidewalk.
History has proven time and time again that new-home construction customers will usually end up spending 8% of the cost of the home on landscape and lawn installation. Another 10% of the cost of the home will usually be spent on hardscape, which will include your front/back walkway and a patio.
While these are preliminary numbers, it will comfortably deliver an average to slightly above average landscape/hardscape project that will contour comfortably with the size of the house. Of course, this doesn’t need to be done right away, but over time this is a fairly accurate rule of thumb of the costs you will incur.
