Investors are committed to bricks and mortar with more than $100 million of office and retail assets changing hands across Sydney in the past week at competitive yields and prices.

It comes as large investors await the outcome of the sale of the Blackstone portfolio of malls, worth about $3.5 billion. The retail portfolio includes Top Ryde City in Sydney and Melbourne's Greensborough Plaza, along with Westfield malls bought from Scentre, Warrawong, Strathpine and Figtree.

One of the latest sales was the office tower at 8 West Street, North Sydney, which sold for $60 million on a sub 5.5 per cent yield to an offshore buyer, while the New Zealand-based Cook Property Group paid $41.32 million for the Entrada shopping centre, Parramatta.

The vendors sold to take advantage of the strong demand for the higher-yielding properties at a time of mixed performance of the sharemarket and low cash rates.

In North Sydney, Property Bank Australia and Security Capital Corporation sold 8 West Street, as the site was attractive to developers due to its mixed use zoning and the changing landscape of the north shore market.

The property was marketed by CBRE's Nicholas Heaton, Sharon Yang, Scott Gray-Spencer and Savills Graeme Russell, Stuart Cox, Neil Cooke and Tim Grosmann.

At Parramatta, the mall was developed by Dyldam in 2011 and was sold by Centennial Property Group.

Ben Cook, director of Cook Property Group, said the Entrada Shopping Centre was a good strategic fit for his Sydney portfolio.

"The anchor tenant, Coles, is enjoying exceptional turnover growth as a result of the centre's prime location. The barrier to entry for a competing development is significant, Parramatta's growth story is compelling and the income generated from the asset is mostly non-discretionary," Mr Cook said.

"This fits with my investment model of acquiring defensive assets in core Sydney locations, with excellent growth prospects."

CBRE Retail Investments' Justin Dowers, Nick Willis, Mark Wizel and Peter Vines negotiated the sale.

Mr Dowers said the sale of the Entrada Shopping Centre "further highlights that the market is pricing strata retail investments at a similar level to freehold investments.

"This is related to the lack of freehold centres offered for sale, but also an increased level of confidence in how these centres perform and the acceptance of this retail platform from the customers," Mr Dowers said.

"Strata retail centres are generally developed in highly built-up areas where major supermarkets have found it difficult to get a presence in. The benefit for owners of these assets is that they generally provide consistent rental growth underwritten by population growth, and the competition risks are much less when compared to outer growth areas of major capital cities."

Mr Willis said the property's position in Greater Western Sydney's growth corridor underpinned strong buyer interest in the asset.

"We received a lot of interest from interstate and international investors given their desire to obtain retail holdings in Sydney – and more specifically the western growth corridor, noting the forecasted population growth in this region," Mr Willis said.

"Investors see this as an opportunity to gain exposure in Australia's most exciting future cities.

Mr Willis said with more than $10 billion worth of development occurring including the Light Rail, Parramatta Stadium, Parramatta Square and the Westmead Hospital, coupled with an estimated 30,000 new dwellings in the region, "the future income potential of Western Sydney will continue to underpin investor confidence".
