Koster’s Outdoor: Sheds and Shed Builders in Albany WA
We design, build and install sheds from 19 Graham Street, Albany. We are a local family business, and we have been supplying and installing in the Great Southern for over 50 years. As shed builders in Albany, we treat a shed as a whole job rather than a flat pack left on the verge: site preparation, engineering, council approval and installation are all part of what we quote, and the steelwork is built and installed by our own fabricators.
Garden sheds, garages and custom steel builds
Garden sheds, garages and larger custom steel buildings all start on the same drawing board. Because we fabricate rather than resell, the size and the layout are yours to set. Internal walls, designer doors and dual levels are all things we build in when a job calls for them, and a shed can be drawn to fit an awkward block rather than the other way around.
Frames are fully welded steel stud walls. Cladding, sheeting, gutters and downpipes come from Bluescope Steel, and we work with Lysaght, CMI, Ampelite and ITW Buildex products through the build. Roof lines can be gable, skillion or curved, so a new shed can be matched to what is already on the property instead of standing out against it.
Options we build into a shed
Fit-out and extras
- Doors: roller, Panelift or sliding doors, fitted as part of the build.
- Flooring: concrete flooring options, poured as part of the site works.
- Ventilation: whirly birds, which matter in a steel building through an Albany summer.
- Natural light: skylights and aluminium glass windows.
- Insulation: energy-efficient insulation options for sheds that will be worked in rather than just stored in.
- Rainwater: guttering and downpipes, with Gutter Guard available.
- Park-A-Lert: available as an extra where a garage is a tight fit.
The door on the front of it
A shed is only as useful as the way you get into it, so we fit the door as part of the build rather than leaving it to someone else. We supply B&D manual and automated doors — panelift or sectional, roller, and everything from a budget door to a designer one. Doors are made to order and measured on site by a qualified technician.
We also service what we install. Our technicians work on all door types, from manual to motorised and single to commercial, and we recommend an annual service. Out-of-town jobs and emergency call-outs cost more than a standard service on a regular service day, and any parts are quoted before they go in. Ring us for the current rate.
Engineering, approvals and what a quote covers
Sheds are designed in house and signed off by an engineer, and we supply the engineer drawings. We also handle Council and Water Corporation approval, which is the part of a shed project most people would rather not deal with themselves. Installation is by qualified installers.
On price, our position is simple: we quote all costs, and there will be no hidden extras. Every build is custom, so there is no shelf price — we work out the job and give you the figure.
