Client/company

Castlemaine Rod Shop is a family-owned business that specialises in building hot rods and manufacturing custom car parts. They've been in the automotive industry for thirty-five years and carry more than six-thousand products. 

The brief 

Marc (owner of the store) contacted us with a set of elevation drawings of an industrial workshop to be attached to the original premises. The workshop needed to meet the existing building which included three different heights and various gutter types. 

After the workshop was complete, Marc approached us again for two extensions, one attached to the new shed and one onto the original building.

Challenges and solutions 

The main workshop structure needed to attach seamlessly to the existing infrastructure which included three different roof heights and gutter types. This was a significant challenge in the design stage to achieve our client's vision. The end result was a tapered width of 24m to 5.8m over a 73m length. 

To ensure the new building was accessible to the CFA for emergencies, a 3m driveway down the side of the angled structure was created. 

We conducted several site visits to measure the existing building, ensuring our custom box gutter system would successfully take water from the attached structures. To achieve this, we set the columns off the existing building, allowing for the correct gutter width.

Client testimonial 

"Our new shed has doubled the size of our factory, it's improved our ability to dispatch and made it a lot easier to get stuff in and out the door. It's a high-quality building and the installers were high-quality tradesmen. I've used Central Steel Build three times in two years and I would recommend them and put my name to their product."
