Commercial and residential property development projects, made simple

Whether you are looking to sub-divide, develop residential apartments or a commercial complex for lease, we are here to make the construction process as smooth, streamlined and efficient as possible. You won’t find the usual complaints of poor communication, poor quality and constant delays. Instead, you’ll benefit from first-class project management, quality workmanship and a swift turnaround time.

Allen Constructions has long-standing relationships with both commercial and residential property developers Central Coast.

If you’re a property developer, you need someone who you can trust with experience delivering efficient projects on time and on budget – no excuses.

The difference at Allen Constructions is that we partner with property developers in Gosford and when we work together, you’re part of the family. We have a vested interest in seeing you succeed, as many of our clients have done in the past.

Where other builders often have complaints around delays, poor communication and lack of quality, we pride ourselves on making sure you’re 100% satisfied with the work. And if you’re not satisfied, we won’t stop working until you are.

“Kim has, at all times, displayed a high level of professional integrity for projects that he is associated with. We would not hesitate in recommending Kim Allen to future clients.
