Room Addition
A single room added to the footprint of the existing home — bedroom, bathroom, office, or playroom. Usually the most affordable addition type.
Your Rhode Island Home Can Give You the Space You Need. Here's How to Get There Without Moving.
A home addition or room expansion can solve your space problem for less than the cost of buying and moving into a bigger home — and it lets you stay in the neighborhood you've already built your life around.
Rising home prices and low housing inventory across Rhode Island and Massachusetts have made moving to a larger home increasingly difficult and expensive. But a carefully planned home addition can often deliver the extra space your family needs — a bedroom, a home office, an expanded kitchen, a family room addition — at a fraction of the total cost of purchasing, financing, and moving to a new property.
Bluestone Homes designs and builds home additions for Rhode Island and Massachusetts homeowners who want more space without the disruption of moving. We manage everything from initial feasibility through permitting, construction, and final walkthrough — as a single, coordinated team.
Types of Additions
Bump-Out
A smaller extension of an existing room, such as expanding a kitchen into a dining bump-out or adding a bay window with floor area. Cost-effective for specific space needs.
Second-Story Addition
Adding a full or partial second story to a single-story home. Highest cost but maximizes square footage without increasing the building footprint.
Attached Garage Conversion or Addition
Converting an existing attached garage to living space, or adding a new garage with living space above.
Honest Cost Ranges
Rhode Island home addition costs vary significantly based on scope, but typical ranges are:
- Single room addition: $40,000 to $100,000+
- Bump-out addition: $20,000 to $60,000
- Second-story addition: $150,000 to $300,000+
- Conversion of existing space (garage, basement): $30,000 to $80,000
