Professional Guidance

Not all architects for home additions can provide the same level of support through all aspects of the addition planning and building process. Knowledge about zoning regulations and building codes is critical when designing an addition to your home. EZ Plans architects are experts at navigating regulatory constraints, whether your property is in a hillside zone, is subject to any special overlay zone, or is located in a historic preservation district.

Our house addition architects and designers know how to get plans for your room additions approved even under the most difficult conditions.

Q. Does a two-story addition cost more than a single-story addition?

Generally, it is less expensive to build a single-story addition. A second-story addition typically requires additional foundation and support upgrades, roof modifications, and a new stairway.

  • Master Suites
  • Home Offices

  • Kitchen & Great Room Expansions
