Hotel Del Coronado

Founders Hall Exterior Canopy and Interior Improvements, Laundry, Power Plant, Ice House Museum, Oxford

Architect: WATG

Project: Historical Renovation

Contractor: Swinerton Builders


Historical Renovation and New Construction of Movie Theater and Restaurant

Architect: SMS Architects 

Location: Liberty Station

Services provided:  Construction Oversight

The Founders Hall project was a renovation of an existing 31,000 SF conference center for the Hotel Del Coronado.  The existing conference center included smaller conference rooms, a smaller boardroom, bathrooms, and storage on the first level.  The second level consisted of a massive ballroom and storage area. 


The renovations included a complete remodel for all spaces as well as bringing the outdated conference center into current code compliance.  The first level saw bathrooms brought to the studs and rebuilt with all new floors, bathroom fixtures, stalls, countertops and tile.  The smaller breakout rooms saw upgrades to electrical systems and data.  New lighting was installed in all areas and partitions revitalized to section off smaller conference areas into further breakout spaces.  The first floor storage was transformed into a working kitchen adding counterspace, commercial dishwasher, refrigerators and a walk-in freezer/fridge.  Also, to make the space more functional, office space was also created on the first level for catering staff to be closer to their events. The second level also includes a complete renovation of the electrical system and data making the space more usable.  New light fixtures were also added to create a more grand experience.  Like the first floor, existing storage areas on the second level were updated to include new kitchen equipment to service food prep for that area.  All areas received brand new HVAC systems and plumbing to create a more comfortable environment.  In addition, the exterior of the building was outfitted with several trellis structures and lighting to better showcase the entry to the space.

Ice House Museum (July 2021)

Built in 1889, the Ice House will be restored to serve as a museum showcasing the hotel’s storied past. Along with permanent and rotating exhibit space, the Ice House Museum will serve as the starting place for the hotel’s history tours, as well as a unique venue for private events.

The Laundry (July 2019)

After serving as the Hotel’s laundry for almost 100 years, the Laundry has received a complete interior and exterior renovation. The brick façade with transom windows has been restored, and the original laundry conveyance systems remain as a tribute to its working history. The Laundry currently serves as administrative space during the build-out of the Master Plan. Future possibilities for this unique and authentic venue include meeting or event space.

Power Plant Meeting Space (July 2021)

Initially built to provide power to the hotel and the island of Coronado, this historic space has been restored and reimagined as a unique co-working and meeting space at The Del. Currently being used for internal offices, the path of travel for guest use was  completed in summer 2021.

As the essence of the Del’s Industrial Area, this building originally built in 1888 has been restored and retrofitted as the Hotel Del’s Facilities Offices. Even though this project completely changed the use and original configuration, several historic elements have been protected in place and showcased; such as fire doors, switch gears, salt pit, brick tunnels, among other things. This remodel includes a unique co-working space & conference rooms that still embrace original elements of the building from the Industrial Era. These areas are accessible to the hotel’s guests.

The Oxford (May 2021)

The Hotel Del Coronado’s Oxford Building is a historic building renovation, with a design focused on the user’s day-to-day needs and bring the building back to life. The Oxford has a very fascinating past. Having been originally built in 1887 as the first hotel on the Island to house executives involved with the construction of the Hotel Del. The building was moved twice. First from near the Ferry Landing on 1st Street to Ynez Place where it served as boarding for female employees of the Hotel Del. In 1983, the Oxford was purchased by the Hotel Del’s owner at the time for $1 and a few years later found its current home in the Industrial Area on property. For the past 30 plus years, it has served as administrative offices for the hotel. 

With the Master Plan re-working the main entry drive to the hotel, the Oxford has become one of if not the first building visitors see as they approach the famed Victorian hotel. The exterior of the building was painted back to its historic color scheme thanks to paint scrapings and photographic evidence. New wood siding matching the original’s profile was replaced on the weather-beaten west façade and new wood windows throughout. The southwest porch was restored to a building entrance to allow for private entry into the Human Resources Department. This porch entry was the original main entrance to the Oxford prior to it arriving on property. The surrounding grounds & west porch stairs were modified to work with the new main entry grades and beautified with landscaping in Hotel Del style. The interior spaces were reworked to fit the current needs of staff and new finishes & building systems were provided throughout. 

Here is to the next chapter in the Oxford’s long life!
