(Lewisville, Minn.) – Altenburg Construction is working to restore Lewisville’s historic bank building, originally built in 1902, and turn it into new office space for the company. President Andrew Altenburg says the three-year renovation project focuses on preserving the building’s early 20th-century appearance, including its original vaults, exposed brick and historically accurate furnishings. The finished building will provide office space for 15 to 16 employees. Altenburg hopes the project will help preserve Lewisville’s history and encourage other businesses to return to downtown. The company hopes to have the building ready for business by next spring.
