There are several considerations to weigh in the decision between razing or remodeling an existing house, from technical and financial to sustainability and design aesthetic. To help with this process, an architect can develop preliminary designs for renovation and new construction to determine feasibility and visualize the possibilities.
- Do existing codes and covenants allow expansion?
Land use codes limit the percentage of a lot that can be built on and put a cap on building height and the amount of floor area. An architect can research the restrictions on a property, providing information for making a decision. - Which is more expensive: remodeling or building a new house?
It depends. Fixing a sub-standard foundation or upgrading a structure for a significant renovation can cost more than starting from scratch. There are efficiencies in new construction that can make it cost less per square foot, but it’s not going to be less expensive if the new house is larger than the existing one. Relocating major elements—kitchens, bathrooms, and stairs—can also tip the balance toward starting new. - Is it greener to remodel or build new?
There is a significant amount of embodied energy in an existing house. Even if a new home is more energy-efficient, it will take decades to overcome the negative carbon impact of new construction. - Is the existing house undervalued compared to the neighborhood?
If other homes in your neighborhood are selling for two to three times the value of your home, the economics work in favor of a tear-down. - How much of the remodeled home will remain?
Building new is less expensive and more efficient if 75% of the existing structure, mechanical systems, and finishes need replacement. - Is the existing house charming details?
The detail and craftsmanship of early 20th-century homes are expensive to recreate in new construction. If you prefer the feel of older homes, remodeling makes sense. - Is it possible to adjust an older home’s layout to allow the flow and openness that match modern lifestyles?
Sometimes, something as simple as enlarging an existing opening can transform a home, but some styles (such as a split level) will take a lot of work to overcome the separate levels. - Can the remodel be concentrated in one area?
Building a two-story addition that adds more space on the first floor and a primary suite above is more cost-effective than renovating spaces throughout a house. - Is the house architecturally significant?
Did a well-known local architect design it? Was it the home of a significant community member, or is it a local landmark? A house does not need an official designation to make it worth preserving. - If you remodel, will it be the house you would have designed for yourself?
Sometimes, the design compromises needed due to existing conditions make even a gut remodel less than ideal. Decide the top priorities for you and your family and ensure that a remodel will meet those needs.
