Adding more living space is one of the most popular home improvement projects in Connecticut. Whether you need an extra bedroom, a larger kitchen, a home office, or a second-story addition, a home addition can increase both your comfort and your property’s value.

- Drainage systems
These elements can significantly affect the budget.
Plumbing and Electrical Work
Projects involving:
- Kitchens

typically cost more because of additional plumbing and electrical requirements.
Interior Finishes
The quality of finishes greatly influences the final cost.
Examples include:
