Home Additions

The key element to any successful home addition project begins with a plan. Structural, mechanical, door and window schedules must be developed prior to submission for permits. It is only with a developed set of drawings that a proper estimate can be completed and true costs established. The costs associated with this phase is dependent on the size and scope of the project. These fees are not included in the construction costs.
