"This well-maintained, modern building has a high stud warehouse with multiple access points through ground level and cart dock roller doors," he says.
"A versatile layout means the building can be easily split, making it ideal for either one large occupant or two smaller tenancies.
"The property excellent amenities, including dual street access and 131 on-site car parks.
"This is an unmissable opportunity to occupy part or all of the largest industrial building available on the North Shore right now."
O'Brien is marketing the property with colleagues Matt Prentice and Ryan de Zwart, and Bayleys' agents Matt Mimmack, Ashton Geissler and Laurie Burt.
Prentice says the property is zoned Light Industry under the Auckland Unitary Plan, with educational uses among the permitted activities.
"With its good mix of office and warehouse space, the building would suit a wide range of activities including education, manufacturing, logistics and distribution," he says.
"Previous occupants have included tertiary education provider Unitec and electronics distributor Monaco Corporation."
Prentice says the building is exceptionally well located close to both the Northern Motorway and the new Western Ring Route.
"The property is in the heart of the established North Harbour Industrial Estate, on the western side of the Northern Motorway, within the wider Albany industrial precinct," he says.
"The area is home to many of New Zealand's biggest and best-known companies, with nearby occupants including Sealegs International, Fujifilm, Electrix and many others."
De Zwart says the building offers two high-stud warehouses separated by a central full-height concrete wall.
"This enables the property to be easily subdivided into two functional, high-quality warehouse tenancies," he says.
"Each warehouse provides a minimum stud height of 6.5m to the portal knee, rising to 7.5m at the apex of the roofline. Each has a single row of internal columns, providing reasonable internal space."
The warehouse at the north of the site has 2981sq m of high-stud space, plus a 50sq m warehouse office.
Access is via two roller doors that are protected from the elements by a cantilevered canopy. An extension to the rear provides two dock levellers.
The warehouse at the south of the site has 2698sq m of high-stud space and 231sq m of low-stud pace. Access is via two roller doors under a cantilevered canopy.
Mimmack says the office, showroom and amenities are located at the front of the property over two levels.
"The well-appointed offices are carpeted and air-conditioned, and offer a mix of partitioned and open plan space," he says.
"High suspended ceilings, wide hallways and glazed partitions lend a spacious feel to the light-filled offices."
The ground floor features a reception, service area and showrooms. Amenities include a staffroom, kitchen, male and female bathrooms, and a gym with showering facilities.
The first floor features a spacious 65sq m balcony at the front of the property.
"The offices can be split into two tenancies as necessary," Mimmack says.
"The tenancy to the north of the site has 525.8sq m of office and amenities on the ground floor and 865sq m on the first floor, along with a 104sq m lobby.
"The tenancy to the south encompasses 1087sq m of ground floor office, 879sq m of first floor office and 234sq m of mezzanine."
Geissler says the property is located on the corner of Unity Drive and Rothwell Ave, the latter of which is a principal thoroughfare linking William Pickering Drive through to the Albany Highway.
"It is a short drive to the Northern Motorway interchanges at Greville Rd to the north and Upper Harbour Highway to the south," he says.
"From there, it is a 15 minute drive to Auckland's CBD outside of peak hours."
Burt says the area benefits from being close to the Westfield Albany shopping centre, North Harbour Stadium and Massey University.
"It is well serviced with cafes, restaurants, bars, gyms and a diverse range of businesses," he says.
"Demand from tenants and owner-occupiers remains strong, with development in the area constituting a good mix of industrial, commercial and retail space."
O'Brien says Colliers International's research shows vacancy rates are reducing as a result of positive demand and no recent development.
"This is a rare opportunity to secure a large industrial space in a sought-after, tightly held area."
