Construction is underway to transform a 1950s office building on the Miracle Mile into a Marriott hotel.

Developer Candleberry Properties and R.D. Olson Construction are now rebuilding the interior of an 11-story tower at 6399 Wilshire Boulevard, which will offer 176 guest rooms under Marriott's AC Hotel brand.  The project is being marketed as "minimalist luxury experience" for business travels, with nightly rates between $250 and $350.

In addition to hotel rooms, the project will also repurpose two rooftop terraces into amenity decks, featuring an indoor-outdoor loung facing Orange Street and a wading pool overlooking Wilshire Boulevard.

Completion has previously been scheduled for 2018.

Across the street, developer NMS Properties has proposed a 15-story apartment tower on what is now a surface parking lot.
