Historic Homes in a Modern Age: Remodels and Additions

The Northwest and greater Seattle area encompasses many historic buildings from the late 1800s and onward in styles ranging from traditional to international and mid-century. These buildings represent the identity and history of a town and its development, and sometimes pay homage to a particular person, architect, or cultural event. H2D has had the pleasure of working on a couple of registered historic houses and is currently exploring an addition project on a home listed in Edmonds. With the relevancy of this project, we are excited to delve into the guidelines and intentions we consider when rehabilitating historic properties.

With most remodels and additions, we are looking at achieving a final project that is three things:

• Respectful. The new work, whether interior alterations or exterior additions, should be sympathetic to the historic building so as not to overwhelm the significant historic features. The project can be just as fresh and exciting even with a thoughtful and modest approach. Paying closer attention at the beginning to making sure the massing, details, and finishes are compatible with the original is well worth the effort.
  
  
• Contextual. On that note, new finishes, materials, and scale should look to the context of the original building for inspiration. This will not only help to blend the style of the new work with the original compatibly, but it will also help with future modifications and resale; a cohesive house with a nod to its historic elements will be timeless and won’t need to keep up with trends.
  
  
• Functional. Historic homes are updated for a reason: we want more from them to live our lives comfortably. This can mean updating the systems of the home: mechanical, plumbing and electrical; installing insulation in the basement, crawlspace or attic; or installing renewable energy systems like solar collectors. Other areas of the home can be more complex; walls of historic homes were built to breathe and adding insulation or a vapor barrier can sometimes cause issues if done improperly. Windows are usually considered one of the most significant features of a historic home and either the repair or the addition of storm windows is strongly encouraged prior to replacement. More information on windows and how to “green-ify” a historic home can be found on the National Trust blog here and here.  Updating historic buildings properly and effectively is important to us!

One of the main aspects of the historic house that we consider before beginning a design is its “historic significance”. When a house or building is listed on a historic register, there will be a list of the elements of the house that are considered significant to its history in the nomination. If these elements were to be removed, the house would no longer be considered historic. In most cases this will refer to the exterior of the home which includes the roof shape, windows, siding and trim, and porches or other original features. Understanding which elements are significant helps us to determine what can and cannot change in the new project.

To do this, we will review the historic nomination for the house and also take a look at the house’s history from records or even simply walking through the building. This research can point out alterations from a later era that should be evaluated before the new project starts. A thorough approach would look to apply the same level of quality and craftsmanship from the original home and consider removing existing alterations that were designed or constructed poorly. Sympathetic additions may also exist and actually add to the house’s history.

Most importantly, new and modern elements should be implemented with the utmost care. New additions shouldn’t destroy or cover historic material or areas considered significant to the history of the house. We look to the Secretary of Interior’s Standards for Rehabilitation and Treatment for Historic Properties for our projects which explain these points in much greater depth.

If you are considering a renovation on your historic home, we would be happy to consult with you on the project!
