Business Philosophy

At ARK Proventus we are inspired by a simple, back to basics approach to real estate investment. For many generations, income yielding real estate has been considered a stable asset class and the basis of wealth preservation. More recently, real estate investment has tended to become overcomplicated. In our view such complication carries many risks. We believe it's time to get back to basics.

The most effective form of real estate investment is achieved by targeting core properties in sensible locations that provide stable income yields and long term capital growth.

We help our clients preserve and increase their wealth by matching them with core property investment opportunities suited to their investment profile. Sounds uncomplicated doesn't it?

That's the how we like to keep it.


At ARK Proventus we build on our extensive network of relationships to source high-quality investment deals for our clients including:

  • Commercial Real Estate Brokerage: this service focuses on the acquisition or disposal of mid-to-large cap real estate assets including buildings and land for and on behalf of our more active investors

  • Joint Venture Development Projects: this service offers both development and private funding solutions to land owners We invite you to join our network of clients and partners, where your will have the opportunity to build relationships with like-minded investors, wealth managers and real estate industry professionals
