Our Story

What began as a man working out of his shed at home fabricating large agricultural sheds and refurbishing boats to service the fishing industry, has grown to a successful building and construction business known as allenCO construction – A team of 9 multi-talented qualified builders, carpenters, electricians, underpinners, earthmovers, plasterers, bricklayers/stonemasons, painters, and labourers that have created a legacy of many happy and satisfied customers.

Founded in 1998 by our director Mark Allen who has worked in the construction industry his entire life, our company has been servicing South Australia from Marla in the north to Coonawarra in the south and everywhere in-between for the last 23 years.

And as our family grew, so has the family business. Through this growth we have perfected our work and stand behind our finished product, ensuring no stone is left unturned in our trusted process to achieve a lasting build and repair that will be of value to your family or business for generations to come.

Built on a strong foundation based on our family’s core values being the pillars of respect, commitment, honesty, recognition, reliability, and reward, we believe it is these values that make us so successful in everything that we do.

Completing a huge variety of residential, commercial, investment, government, private, and corporate projects, we will continue to build South Australia for many more years to come.
