North Harbour former Unitec building

A spacious modern warehouse, showroom and office property in the sought-after North Harbour industrial area of Auckland's North Shore is for sale.

Previously occupied by Unitec, the prominent property at 10-12 Rothwell Ave is offered for sale by deadline private treaty closing on December 6, unless sold earlier.

Featured in the latest Colliers Portfolio, launched yesterday, the property is being jointly marketed by Jimmy O'Brien, Ryan de Zwart and Matt Prentice of Colliers International's North Shore office, and Sunil Bhana and Matt Mimmack of Bayleys.

O'Brien says the prominent 9719.9sq m industrial building has broad appeal.

"This prime property is ideal for both national and international companies seeking to own and occupy a large, versatile warehouse space," he says.

"Alternatively, investors should inquire as there could be some significant upside if purchased and tenanted later."

Located on a 1.43ha site, the standalone building has 5910sq m of warehouse and a further 3809.8sq m of office and amenities.

"The functional high-stud warehouse has been designed to suit a wide range of business uses. It is fully equipped with fire sprinklers, allows for high-stud racking, and has multiple roller doors," O'Brien 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 has excellent amenities, including easy access to motorway interchanges, dual street access and 131 on-site car parks."

De Zwart says the building is exceptionally well located close to the SH1 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 encompasses 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 has 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."

Prentice says 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 has 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.

Prentice 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 with 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."

Bhana says 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 has a spacious 65sq m balcony at the front of the property.

"The offices can be split into two tenancies as necessary," Bhana says.

"The tenancy to the north of the site comprises 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 has 1087sq m of ground floor office, 879sq m of first floor office and 234sq m of mezzanine."

Mimmack says the property is located on the corner of Unity Drive and Rothwell Avenue, 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 Road to the north and Upper Harbour Highway to the south. From there, it is a 15 minute drive to Auckland's CBD outside of peak hours."

Mimmack 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."
