Types of Home Additions We Offer

Major Additions: Multi-Room Expansions and ADUs

Major additions are ideal for homeowners looking to significantly increase living space and functionality. These additions often include multiple rooms and involve integrating complex systems like electrical, plumbing, and HVAC. Common major additions include:

  • Accessory Dwelling Units (ADUs) for in-laws, guests, or rental income
  • Two- and Three-Story Additions to add vertical space
  • Multi-Room Expansions that can accommodate additional bedrooms, bathrooms, and living areas

While major additions require a larger investment, they provide substantial added value, transforming your home with maximum impact.

Single Room Additions: Affordable & Efficient Expansions

Single room additions are the most popular way to increase functional living space without significantly altering your home’s existing footprint. With minimal changes to existing systems, a single room addition is both cost-effective and versatile. Popular options include:

  • Living Rooms for family gatherings and entertainment
  • Expanded Kitchens for additional cooking and dining space
  • Home Offices for a productive workspace
  • Bathrooms and Laundry Rooms to add convenience
  • Mudrooms for storage and organization

Each single room addition is designed to integrate seamlessly with your home’s layout, creating a functional, comfortable space that meets your family’s needs.

 

Bump-Outs: Small Changes with a Big Impact

For those looking to add just a bit more space without extensive remodeling, bump-outs are the perfect solution. These small expansions extend a specific area of your home, offering extra square footage without requiring major system alterations. Ideal for:

  • Utility Spaces to accommodate appliances or storage
  • Closets for added organization
  • Fireplaces or Sitting Areas for a cozy retreat
  • Lean-To Storage or Doghouse Bulkheads to increase functionality

Bump-outs are a great way to maximize your home’s potential without the need for a full addition, giving you extra room exactly where you need it.
