Tips for a successful (within budget) home addition:
Communication
Clearly communicate your wants. Do the research and determine what kind of flooring, windows, roofing, paint, etc. that you want. The more details you can give your contractor, the more accurate the cost estimate of your home addition will be.
Compromise
Be willing to compromise to stay within budget. For example, it may be necessary to limit the square footage of the addition, reduce the number of plumbing fixtures, or select more affordable materials.
Consistency
Take your time creating the design plan and stick to it. Contractors have a strict method of ordering the job steps. If a change of heart results in subcontractors retracing their steps or undoing their work, then this will inevitably increase the estimated budget.
Tips for “Blending” a home addition:
A home addition can stick out like a sore thumb if it isn't done properly (another reason to hire a licensed, professional contractor). Homeowners often wonder: “How do you blend your home’s exterior with a new addition?”
There are some things you and your contractor can do to build a seamless home addition.
- Choose a reasonable size for the addition, allowing the original structure to take center stage.
- Consider adding to the back of the house to preserve the forward-facing architecture.
- Match the new roof with the angle and proportions of the existing roofline.
- Match the roof materials, exterior siding, exterior paint colors, and windows.
- For older homes, incorporate salvaged or recycled materials to maintain the historic feel.
