The Life Style Store History

The Life Style Store first opened its doors in February 2002 in the Riverbank complex in Parramatta. It was started by three individuals with a passion for quality home and car entertainment products. Having had vast experience within Australia’s largest car audio retailer at the time, the staff were determined to take that experience and develop a business that could take the home theatre and car audio experience to another level.

In mid-2004, the Riverbank complex was sold and the company relocated to its current premises at The Junction in North Parramatta where we have been for over 16 years. Over time the showroom has been expanded to include 17 home entertainment demonstration rooms.

In 2021 a further expansion was commenced to showcase a simulated fully automated home and new Automotive categories. The showroom’s vast array of demonstration rooms and facilities allow you to audition the true home and car entertainment experience as well as home automation systems before making your purchasing decision.

Life Style Store’s retail showroom is based in the fast-growing Western Suburbs/Hills region of Sydney, however the store services customers from all over Sydney and Regional New South Wales.

Whilst a competitive price is always of importance, the quality and suitability of the product are even more important and that is the mantra of the Life Style Store. We will design the right system with the correct components to provide you with the performance and functionality to suit your needs. We are also focused on providing you with the best available products on the market for your requirements, so we have made the conscious decision to not import our own brands so that we can remain impartial. We offer a wide range of products from a carefully selected range of brands which we offer without any bias other than towards their performance, reliability, and value-for-money. You won’t find any low-quality brands at the Life Style Store. Vinod, the company’s co-founder says: “We plan to be here for a long time, so don’t want to waste our time on poor quality products. We want our customers to come back and recommend us to their friends.”

At ArchiPro we recognise and acknowledge the existing, original and ancient connection Aboriginal and Torres Strait Islander peoples have to the lands and waterways across the Australian continent. We pay our respects to the elders past and present. We commit to working together to build a prosperous and inclusive Australia.
