OXFORD — A plan to build a 90-room hotel across from the Oxford Casino has taken a major step forward.

The developer has completed permitting and design phases of the project and Hilton Worldwide, owners of the Hampton brand, has given final approval.

The $15.4 million Hampton Inn should be complete before the end of the year.

Oxford-based developer Casalinova Development Group tells the Sun Journal it will now transition the responsibility for construction to Quincy, Massachusetts-based owners GIRI Hotel Management. The group operates a range of hotel brands in New England.
