How to Calculate the Cost of Northern Virginia Additions

Filed Under: Additions    by: Steve Kayhill

Building a home addition in Northern Virginia increased your living space, enhances property value and allows you to customize or alter the existing floor plan. But many homeowners wonder how much to budget and need an accurate way to calculate the cost of Northern Virginia additionsNorthe. With a few general questions, some idea about design and sizes and a trusty calculator, we can guide you through the process to come up with a rough number.

Understanding the Additional Costs of Additions

New construction avoids several steps, including demolition and retrofitting. These steps drive the cost of home additions higher. Most contractors agree that the construction costs of house additions can be anywhere from 25 to 50 percent higher than new construction costs.

Architect fees should be included in any construction budget, and the services of this professional help to overcome many of the obstacles common to home additions. Blending rooflines, structural walls, landscaping and elevations requires skill and an eye for the overall design. Architects fit the bill perfectly. Expect their fees to reach between 5 to 15 percent of the total construction budget.

Although it is difficult to narrow down the cost of a typical home addition in Northern Virginia, expect to pay between $80 and $150 per square foot for basic construction. Remember that several key elements influence this price range.

Electrical and Plumbing

The cost of simple Northern Virginia additions, living rooms and bedrooms for example, is significantly lower than the construction cost of a kitchen or bathroom addition. Electrical and plumbing drive up estimates, depending on your tastes and the work required to install these elements.

Choose the following items for your home addition, and add the cost of each to the estimated square footage price above:

  • Bath or Shower (or both)
  • Toilet
  • Sink
  • Faucets and Taps
  • Lighting
  • Exhaust Fans
  • Heating Lamps or Radiant Underfloor Heating

High end bathroom fixtures, taps, lighting and heating design add to the construction cost, which is often calculated based on standard fixtures.
Difficult or complicated circumstances require more labor for installation, increasing the project cost. Will your contractor need to rewire the existing electrical system to accommodate your home addition? Or will the plumbing design need to be reworked to maintain flow and proper drainage? An experienced builder can easily handle these situations, but the added time increases your cost.

The Value of a Written Estimate

Whatever the size of your home addition, and whichever electrical and plumbing fixtures chosen, be sure to obtain a written estimate before the project begins. This quote should outline the work in as much detail as possible, including:

  • Specifications of the project, such as size and location
  • Details of materials, including brand names and product numbers where applicable
  • Approximate scheduling
  • Labor included
  • Warranty
  • Payment details, such as deposit and draw details

It helps to discuss the project details with your contractor, but with some discussion and a few key decisions, you should be able to calculate the cost of Northern Virginia additions. Use this figure to create a rough budget and arrange for financing. The numbers may change as your project takes shape, but this basic calculation is a wise first step.

    It’s always best to have a little cushion when it comes to the budget. As a remodel project comes along there may be unforeseen costs that are necessary in order to keep the process moving as it should.

    Yes, estimation on the project costs will help a lot on the specifications and on the unforeseen cost and changes. Details and labor are hard to quantify but with careful planning and cost accounting, this can be done. Thanks for the information!
