- Type of Addition – Adding a sunroom versus a second story involves different levels of complexity.
- Square Footage – Naturally, the larger the space, the more materials and labor are required.
- Foundation Work – Some projects require excavation or foundation reinforcement.
- Utilities – Incorporating plumbing, HVAC, or electrical systems can affect the final scope.
- Finishes & Custom Features – From high-end flooring to custom cabinetry, finishes play a big role.
At Bonsai Builders, we walk you through all these elements to make sure your addition is built to last and tailored to your lifestyle.
