Room Additions

  • Bedrooms: Adding an extra bedroom is common for growing families or to accommodate guests. This can involve extending the home’s footprint or converting existing spaces like attics or basements.
  • Bathrooms: Additional bathrooms can alleviate morning rush-hour traffic in the house. Options include full bathrooms with tubs and showers, half-baths, or powder rooms.
  • Living Rooms and Dens: These spaces provide more room for family activities, entertaining guests, or simply relaxing. Larger, open-plan living areas are especially popular.
  • Home Offices: With the rise of remote work, dedicated home offices have become essential. These spaces are designed with work efficiency and comfort in mind, often including built-in desks, shelving, and ample lighting.

Kitchens and Dining Areas

  • Kitchen Extensions: Expanding a kitchen can significantly improve its functionality and aesthetic appeal. This might include adding more counter space, cabinetry, or a kitchen island.
  • Dining Rooms: Formal dining rooms or expanded eat-in kitchens provide more space for family meals and entertaining.

Outdoor Living Spaces

  • Decks and Patios: Adding a deck or patio enhances outdoor living, providing a place for dining, lounging, and entertaining. These can be simple or elaborate, incorporating features like outdoor kitchens, fireplaces, or hot tubs.
  • Sunrooms and Screened Porches: These additions offer a way to enjoy the outdoors year-round, protected from the elements. Sunrooms often feature large windows for maximum sunlight, while screened porches provide a bug-free environment.

Garage Additions

  • Attached Garages: Expanding or adding an attached garage can provide secure parking and extra storage space.
  • Detached Garages: These can be used not only for parking but also as workshops, hobby spaces, or even guest quarters if designed as a multi-purpose structure.

Accessory Dwelling Units (ADUs)

  • ADUs, also known as in-law suites or granny flats, are self-contained living units on the same property as the main house. They typically include a kitchen, bathroom, and living area, and are ideal for multi-generational living or rental income.

Second Story Additions

  • Adding a second story is a major renovation that effectively doubles the living space without expanding the home’s footprint. This is especially popular in urban areas where lot sizes are limited. It can accommodate multiple rooms, such as bedrooms, bathrooms, and even small apartments.

Attic Conversions

  • Attics can be converted into additional living spaces. This is often used for extra bedrooms, home offices, or storage.


  • A mudroom provides a transitional space between the outdoors and the interior, helping to keep the home clean and organized. These spaces typically include storage for shoes, coats, and sports equipment, and sometimes a laundry area.

Considerations for Home Additions

When planning a home addition, several factors should be considered to ensure the project meets your needs and adds value to your property:

  • Budget: Establishing a clear budget is crucial. Costs can vary widely depending on the type and complexity of the addition.
  • Permits and Regulations: Building permits and adherence to local building codes are essential to avoid legal issues and ensure safety. Our experts will take care of this for you.
  • Design and Aesthetics: The addition should blend seamlessly with the existing structure, both in terms of architectural style and materials.
  • Functionality: The new space should address specific needs and enhance the overall functionality of the home.
  • Resale Value: Consider how the addition will affect the home’s resale value. Some additions, like extra bedrooms and bathrooms, typically offer a good return on investment.

Home additions are a strategic way to improve a living environment, accommodating the evolving needs of your home while potentially increasing property value. Whether it’s a simple deck addition or a complex second-story extension, careful planning and execution are key to a successful project. Each type of addition offers unique benefits, contributing to a more functional, enjoyable, and valuable home.
