What we do.

At Merrigang Construction, we primarily focus on residential construction projects. We can support you through your build or renovation project from the initial consult, through to construction and handover, and will manage every aspect so that you don’t have to. Through our knowledge and expertise, we are able to provide guidance and direction through all decisions and are dedicated to helping you to realise your build or renovation dreams.

Whether it be a simple bathroom or kitchen renovation, a new deck, granny flat conversions or a large extension, we are here to manage every aspect of your next project, regardless of scale or complexity. We aim to provide exceptional quality, out of the box solutions and cost-effective methods to ensure every project exceeds client expectations.

We service the Southern Highlands, South Coast and Illawarra region.

What you can expect. 

When you engage Merrigang Construction, you can expect timely, open and honest communication. Our two directors are dedicated to providing a thorough service from concept to completion on every project they take on. Rico and Jack offer initial consultations prior to engagement to ensure that Merrigang Construction is the right fit for you and to assist in establishing a direction and plan for your project. They will draw on their experience and expertise, and their relationships with architects, designers, council and certifiers to help take the stress out of what can often be a complex process with a lot of red tape.

Upon engagement, Rico will work closely with you on budget and cost planning and the development of a project program and schedule that is realistic and achievable to avoid unnecessary delays and eliminate unforeseen issues. For the duration of your project, Jack will lead a team of in house carpenters and sub-contractors to ensure that things are run smoothly and completely to the highest level of quality.

Meet the Team.

Merrigang Construction is led by Jack Parish and Rico du Plessis, who between them, have over 25 years of experience within the construction industry. Prior to starting Merrigang Construction, both Jack and Rico worked extensively across both the commercial and residential construction sectors managing and completing a large variety of projects, from renovations to new builds, commercial fit outs and refurbishments, and everything in between.


  • Director | Construction

    Coming from a carpentry background, Jack is a highly qualified builder with experience managing and completing high end construction projects in Western Australia, Victoria and rural New South Wales.

    Jack has strong management skills and is experienced in leading large teams of sub-contractors. He is passionate about high quality service and communication and has a hands on approach to managing each build from establishment through to completion.

    As a self-professed perfectionist, Jack brings a high level of organisation and professionalism to all projects and is passionate about delivering exceptional quality to clients. He prides himself on visibility and is present and highly involved in every job taken on by Merrigang Construction.

    When not working, Jack leads an active lifestyle and enjoys running around with his two children and enjoying a glass of wine with his wife.


  • Director | Project Management

    Rico du Plessis has been working as a project and construction manager since 2014. Prior to moving down to the Highlands, Rico worked in Sydney as a project manager in commercial fit out and has since transitioned to residential work, finding it both creative and rewarding.

    He has extensive experience in team management and is committed to transparency and trust. Rico specialises in budget and cost planning, forecasting, programming and scheduling, and is responsible for all of the back of house management at Merrigang Construction. He is extremely passionate about what he does and values positive relationships with both his team and clients.

    Outside of work, Rico can be found spending time outdoors with his wife and three young children. He is immersed in life in the Highlands, and enjoys the opportunity to be a part of the community, whether it be down on the cricket field or on the rugby sideline.
