101 Sepulveda

101 North Sepulveda is a 3-story office building prominently positioned on the northwest quadrant of Sepulveda and El Segundo Boulevards in the Smoky Hollow area of El Segundo. The landmark building was built in 1984 and has undergone significant changes to become Smoky Hollow’s newest “Class A” creative office building. The renovations included a new distinctive façade, renovated common areas, upgraded subterranean parking structure, and the build-out of a sky deck to take advantage of the views.

The unique characteristic that sets 101 apart in the funky Smoky Hollow area is the spacious 30,374 s.f. floor plate for a large creative user (part of a larger 70,000 s.f. floor). Currently the building is leased to leading-edge tech and new media companies and includes exposed 14’ ceilings, polished concrete floors, extensive window lines, natural light and collaborative open space. The building has been awarded the Energy Star label for its operating efficiency for the last six years and offers a solid, secure infrastructure.

Paul Solomon’s 6171 Blvd project is a three (3)-story interior and exterior renovation of an existing office building in the Los Angeles International Airport Submarket. The 6171 Century project marks the turn of the LAX submarket towards a new kind of business space/need. The revitalization begins with this 92,000 s.f. office space inclusive of: new facades, office buildouts and direct views of the International Airport.

To allow for maximum flexibility for future leasors, Oltmans scope of work included demolition of the existing three (3)-floor interior space, updating the existing HVAC and elevators and updating the 1st floor building facade, lobby and owner’s suite, while leaving the rest of the building as open spaces to be specifically fit to future leasors. Tenants already onboard include Hensel Phelps, M-Theory, Stella Travel Services and Team Rubicon.

The 1st floor lobby itself, features ribbon-glass fronts along three sides of the building featuring a geometric folding ceiling made of wood. The architectural folding ceiling leads into the lobby and down the vertical spaces and is complimented by the building’s existing concrete floors.

Building Specifications include:

  • Uninterrupted ribbon windows
  • 13’ Floor to deck ceilings
  • Concrete floors
  • Wood folding ceiling

Corporate Center IV

This 102,562 s.f. project was a type III-1hr., three story concrete tilt-up above grade building with one level of subterranean parking. It required proper shoring installation to protect the existing buildings that surrounded the project and allowed for construction of the below grade parking structure. Substantial sequencing of the construction process was required to build the tilt-up panels over the subterranean level, where the panels were attached to a structural poured-in-place deck over masonry walls and poured-in-place columns. A three story structural steel frame was built adjacent to the concrete tilt-up panels to contain the lobby cores, which included stairs and elevators. The steel was covered in a metal and dual glazed curtain wall with exterior plaster, along with contemporary precast columns and plaster accents. The building contained one level above grade parking as well as two floors of rental office space. The lower floor level was constructed with structural steel beams and metal decking with the upper floor and roof constructed of glue laminated beams.
