5 Things to Know for a Seamless Home Addition

You’re itching to extend a space in a particular area of your home, and now, you’re ready to take the plunge. 

Hold on. 

Before you do anything drastic, there are some things you need to know to ensure the complex project of home additions blends seamlessly with your home. 

  1. It All Begins with the Foundation

How strong is your home foundation? Before you add anything to your home, you need to ensure your foundation is strong enough to support the new addition. Otherwise, it could cause structural issues that will turn into bigger problems down the line. 

One thing you need to be sure of is that the foundation is deep enough to go below the frost depth, depending on the geography of your area. When you build above the frost depth, this will shift over time that will cause problems. 

Another thing is to ensure that the foundation type is right for the soil type in the area. Otherwise, this may cause shifting issues. 

Finally, you need to match the type of foundation in the existing structure with the one you will use for the new addition. Doing so will ensure the addition is level, strong, and seamless. 

  1. It’s Also About Building Codes and Zoning Laws

Local building codes and zoning laws dictate whether a homeowner can build a home addition on their property. So, before you get in too deep with your project, you need to consult your local government first. Identify any restrictions to prevent any hassles down the line. 

  1. It Should Match Your Exterior

The new room in your house should blend with every detail of your home exterior, which includes: 

  • Windows
  • Sidings
  • Trim
  • Doors
  • Hardware
  • Paint colour

However, some don’t have to be the exact match. For one, the roof should closely match the rooflines on the existing home, which means you need to find something that will replicate the spacing, soffit style, pitch, eave depth, and rafter size. In that case, a new roof is something you can explore if you don’t want to go through the trouble of finding the perfect roof match. 

When matching it to the siding, make sure the existing siding hasn’t faded; otherwise, replacing everything is the best thing to do here. 

Finally, windows and doors are easier to deal with, thanks to the wide selection of custom windows and doors today. 

  1. It Should Match the Interior Addition Design

Now, let’s work on the inside! The new room addition must blend seamlessly from the inside. Similar to the exterior, match elements like window casings, crown moulding, paint colours, and light fixture styles to stay consistent. 

  1. It Should Take Into Account the Landscaping

Don’t forget your landscaping when building a new room addition. Consider landscape aspects into your home remodelling budget and plan to ensure that everything blends well together.
