Step #1 - Find & Secure Your Land

When you take the first step toward building your dream home, your journey typically begins with the search for the right piece of land. One common assumption that people make while searching is that they can build their dream home on any land, as long as it’s for sale as a lot. Unfortunately, this is not correct, and the wrong land purchase can end up causing quite a few problems.
Our land development services are critical to the success of your dream home.
There are many factors that can affect not only whether a lot is buildable, but whether the lot is the right choice for your particular homebuilding needs. We have had clients in the past come to us and say, “I have this beautiful lot, and I want you to build my dream home there.” Unfortunately, there are times when the lot they have chosen even though it was beautiful, they couldn’t put the exact house they wanted on the lot.

Obviously, we want to help you to avoid making the wrong land investment. The earlier you can bring us in on the process of finding your desired land, the better. We enjoy evaluating land and potential teardown opportunities so you can build your dream home. We can also provide sitework estimates based on the lot or teardown that we are evaluating.

A few of the areas we will look at…


First, we can help you navigate the zoning requirements in the town you want to live in.  Some important considerations include limitations on how large the home can be or what the floor-area ratio can be.  There also are setback requirements that dictate how far your home needs to from the edge of your property line.


Checking out utility availability can also make a big difference later on, especially since some utility options can be more expensive than others in the long run. Depending on the location your water will come for city water or well water.  If your property requires a well, we can look at surrounding wells to find out the availability quantity and water

We can help determine the costs involved if your home will be connected to city sewer or will require a septic system.  Septic systems work great but typically cost much more than tying into city sewer.  

When it comes to wired utilities, we will evaluate electrical, cable and telephone lines coming into your home.  We can help determine if they can be underground or if they have to be overhead and the costs involved to connect to them.


The last thing anyone wants is a flooded basement or a muddy puddle in your yard as large as a pond. This can become a major issue if land contours aren’t considered at your potential building site. 

We will help ensure the topography of your land slopes away from where the house will be placed so rainwater can drain in the right direction. 

We also will look at your soil’s water table and what the percolation rate is, which is how fast the soil can absorb water. 

We help evaluate the possibility of using a gravity footing drain or a sump pump to aid with drainage. Ideally, we want gravity fed drainage systems. 

In short, drainage is such a critical component to think about before you buy any lot. We are happy to evaluate the best drainage scenario for your desired lot.


Choosing the wrong plot of land can suddenly turn an affordable dream home into a money pit.  To avoid that from happening, we can help you estimate what sitework will cost on a particular lot.  For example, we will look at:

  • How much will it cost to dig and backfill the house?
  • Is there ledge that can affect your building cost? 
  • Is there a high water table?


Those are just a few of the things I look at. Sometimes if ledge is a concern, we may suggest raising the foundation slightly to avoid the blasting costs and rock removal. With that, we can bring in general fills to the landscape around the foundation.

Estimating building costs isn’t an exact science, but turning to a properly experienced builder like Duffy Construction Custom Homes can make a huge difference.  We can give you hard numbers on what it will cost to build from the concrete up, but we can’t do that with building costs related to the land.  We don’t know exactly what we’ll find, until after we start digging. With land, those numbers can’t be fully set in stone. However, we can still provide fairly reliable estimates when it comes to the sitework budget. Most often, we are able to keep our clients within their budget range.

Step #2 - Pick Out Your Floor Plan & Layout

If you currently have floor plans, we would be happy to discuss costs to build based on your plans and selections.  

If you currently do not yet have plans, we recommend starting at the www.TheHouseDesigners.com which has thousands of plans to choose from.  

During your complimentary consultation with us, we will give you a ballpark estimate to for what you want to build based on your selections.  You do NOT have to everything picked out in order for us to give you a ball park estimate.  If it makes sense to explore your custom home build further and give more accurate pricing and/or help you with a your design, we will most likely recommend you hire us for our design agreement.  You will get 3D renderings, floor plans and a mini virtual tour of what you want to build (like you see below).  Our design agreement will help ensure we are on the same page and also allows us to provide you more accurate allowances and pricing.  


Step #3 - Determine Financing

If you are not planning on paying cash, we have relationships with national and local lenders that can help finance your new construction.

Beyond cash and traditional financing, there are other construction financing options.

Step #4 - Build Your New Home

From the initial consultation through project completion and beyond, you’ll experience the difference. We are excellent communicators. We listen to your questions and ideas and translate those into your wants and needs. You’ll never worry if your concerns are being addressed because the details are as important to us as they are to you!  We have great relationships with many subcontractors and suppliers to help ensure your home is built on schedule and on budget.  We look forward to talking with you about your particular new home during your complimentary consultation which you can schedule here right now. 

We will build your new custom home like it’s our own.
