We are the top choice for custom barns on the Sunshine Coast and Gympie


1. Do you take care of slab and erect?
CKNR Pty Ltd trading as Coasteel Buildings Sunshine & Gympie is QBCC licenced (Lic No: 1061436) to complete your shed, garage or carport from council application to completion. We are not licenced plumbers, so we do not undertake storm water connection – your downpipes will be installed to ground level only. We only use experienced QBCC licenced subcontractors for concreting and erect works as we require a quality finished product at all times.

2. Are the kits easy to erect as an owner builder?
Yes. We include the columns, rafters, haunch and apex brackets all pre-punched and ready to bolt together, an erection guide and a bill of materials, as well as hand drawn pages exclusively for your building. These drawings show wall girts, roof purlins, door header heights, information on where to start sheeting on the gable ends, and a slab layout plan. Of course, we are also available for advice when you need it.

3. Is there a range of colours available?
There are 20 modern colours available in the Blue Scope Colorbond Steel Range, as well as standard Zincalume. You can choose different colours for your walls, roof, gutters, flashings, barge and doors.

4. Do the kits come with engineering for council?
Yes, a full set of engineering drawings (specific to your building) is available to you once we are in receipt of a signed contract and a deposit. We can also lodge your council application for you.

5. Does the engineering include the slab and footings?
Yes, our sheds are engineered for A, S or M soil types. Slab and footings engineering for soil types other than these can be arranged, if required, but soil testing is generally not required for a garage slab by most councils.

6. Can my building be erected onto footings without a slab?
Yes, your shed or carport can be erected on ground level footings or embedded into the footing, if preferred to a slab.

7. How are your buildings anchored to the slab or footings?
Each building is designed to be anchored with Dynabolts or hold down bolts set into the concrete.

8. I have some roller doors and windows of my own. Can you build the garage to accommodate them for me?
As long as we are given accurate heights and widths, we can organise the kit to use your doors and windows.

9. I have a four wheel drive vehicle. What height garage will I need for entry under the roller doors?

With most garages the height is determined at the eave where the roof sheet meets the wall sheet, but your clearance height under your roller door will be considerably less due to the depth of the drum of the door. Below is a guide to garage heights and clearance heights under roller doors.

Garage wall height x door clearance approx. 

  • Wall 2.4 metres x door 2 metres
  • Wall 2.7 metres x door 2.3 metres 
  • Wall 3 metres x door 2.6 metres

10. Is it easy to extend the length of my building at a later date?

Yes. Unlike many other manufacturers that utilize a smaller end portal frame, our engineering uses mullion supports of the same size as the portal frame, making it very simple to add more portal bays and extend later.

11. Can I add a side awning at any time later?

Yes, this is as simple as cutting a neat slot in the wall sheets at each portal frame, inserting a flat plate bracket to pick up the column inside, and bolting the rafter to it outside the wall to extend the awning you choose.

12. I have a steeper roof pitch on my house. Can I get a steeper roof pitch on my garage?

Yes you can. Our roofs can be 11 degree, 15 degree, 22 degree, 30 degree, 45 degree as well as the "Mansard" barn roof and Dutch gable.

13. What deposit is needed to place my order?

The deposit amount depends on the type of works involved.  If it is domestic building works, the deposit amount is governed by the QBCC – 10% for contracts less than $20000 and 5% for contracts over $20000. If it is a farm shed/non-domestic building works or a kit only sale, we ask a deposit of 30% of the price of your kit. If you wish to do your own council prior to the order, we will accept a minimum engineering deposit of $500 with the balance of deposit due prior to ordering the kit.

14. What is the time frame from ordering my kit to it being delivered/built?

For kit-only sales not subject to council approval being completed, there will be a lead time of about 3-4 weeks from order to delivery time. For fully built jobs, the completion time is about 6 weeks from receipt of council approval.

15. Will my building be covered by a warranty?

Yes, the Bluescope Steel 15 year warranty applies (with conditions). If your shed or carport is constructed under a domestic building works contract you will also have the peace of mind of the QBCC Home Warranty Insurance Scheme.

16. What does BCA (Building Code of Australia) importance level mean?

Level 1 – Buildings or structures presenting a low degree of hazard to life and other property in the case of failure e.g. a hay shed.

Level 2 – Buildings or structures presenting a moderate degree of hazard to life & other property in the case of failure e.g. domestic buildings – houses, garages and sheds.

Level 3 – Buildings or structures designed to house a large number of people e.g. school buildings.

Level 4 – Buildings or structures essential for post disaster recovery or hazardous facilities e.g. hospitals and power stations.

17. What does terrain category mean?

Terrain Category 1 is exposed open terrain for a 10km radius, no trees, other buildings or hills.

Terrain Category 2 is open terrain with a few trees and surrounding buildings (normally a paddock).

Terrain Category 2.5 is small acreage blocks.

Terrain Category 3 is suburban backyards.

18. What does wind region mean?

Australia has 4 wind regions, A, B, C and D. Most of Australia is Region A, however South East Queensland (up to 100 km inland) is Region B. Prior to providing you a quote, we will confirm which Wind Region your property is situated in to provide the optimal building for your site.
