Developers renovating the historic downtown Midland Building into a four-star, boutique hotel plan to open in the spring.

Surety Hotel, located at 206 Sixth Ave., will have 138 rooms, a 200-person ballroom, meeting space and a private outdoor courtyard. The Mulberry Street Tavern, a restaurant and bar, will open on the first floor.

The Chicago-based Aparium Hotel Group has shared new images of the space with the Des Moines Register.

"The Des Moines market is experiencing incredible growth, and the expression of culture we are seeing through emerging art, entrepreneurialism and development is among the most exciting we have witnessed across the country," said Mario Tricoci, co-founder of the Aparium Hotel Group, in a news release. "We are very much looking forward to opening the Surety Hotel as downtown continues to thrive."

Aparium Hotel Group started its $40 million historic renovation in January. The 12-story building will be a revival of an "architectural gem" built in 1913 for The Iowa Loan & Trust Company, according to the release.

Surety Hotel is named after a type of financial transaction from the original business — a surety bond.

The 106-year-old building was once Iowa's tallest skyscraper. It's had several names, including the Hippee Building, the Southern Surety Building and the Savings and Loan Building. It has been known as the Midland Building for nearly four decades.

Most recently, it was home to several tech and startup firms, a court reporting business, other offices and Scooter's Coffee.

Aparium Hotel Group purchased the building in 2017. The firm is known for renovating historic buildings into upscale hotels and has a portfolio of lodgings around the Midwest, including Chicago, Minneapolis, Kansas City and Omaha.

Surety Hotel's rooms will be about 300 square feet each. About 10% of the rooms will be suites.

"Guests can expect unique amenities from Des Moines makers, and rooms that boast remarkable views of the East Village and the Capitol," according to the release.

Details on things like room rates and the restaurant and bar menus are still being worked out.

Des Moines committed $4 million in the form of tax increment financing for the project. Aparium Hotel Group also received $4.7 million in state historic tax credits.
