NickGFBPHi everyone, My name is Nick Kay and I am in the Building Industry here in Perth, Western Australia. My company name is Concept Steel Constructions ( and we specialize in custom built, energy efficient granny flats, micro and kit homes here in Perth and surrounding suburbs. I hope you don’t mind me taking a bit of your time to share my story about why I’m in this business and how I can help you get a better home of your own the “no bullsh** way! That’s right! I’m sure that by the end of this letter you will not doubt that I am a “REAL” person and that I can give you the right advice and build your dream home with an “old school” attention to detail and remain within your budget. ‘No bulls@#*t!’ Is what I have heard so many times, “Thank you so much for making it all so easy and being so honest!” or “Wow! I can’t believe the quality at such an affordable price!” I have always loved making and fixing things (or pulling things apart to see how they tick…) my Grand Dad was a big influence when I was young and I loved spending time with him learning about tools and hardware. I was really keen to leave school after year 10 but my parents wouldn’t let me unless I had an apprenticeship or “something worthwhile” to go on with. I found school boring apart from Woodwork and Manual arts subjects and suffered the same comments on my report cards: “Has the ability to achieve anything he sets his mind to” and “Achieves results when he applies himself…” I knew I wanted to be a builder since I was 12. I left school halfway through year 11 (16yrs old) to do a Carpentry/Joinery pre-apprenticeship. Finally, I had a chance to learn something interesting. I finished second in my class and was offered apprenticeships by several companies. I completed my 4-year apprenticeship with the Group Training Scheme and did contracting for several commercial companies from working in Transportables at Ausco to becoming the Site Supervisor on commercial building sites for a small builder. I registered my company Concept Carpentry WA P/l and employed 2 people and myself, building transportable buildings for Ausco Transportables. I was 23 when we ran out of work and needed to find some work fast! The economy was slow and there wasn’t much work around. My parents owned a garden centre on Armadale Rd in Forrestdale. Armadale Rd was a busy street even back then… Then I had an idea to get us all some work– Build a steel gazebo out the front of the Nursery and see if anyone is interested in buying it… So that’s what we did. It worked amazingly well and lots of people ordered gazebos and patios! It wasn’t long before we were all busy and working flat out. I borrowed some money and set up 6 display patios most of which are still at our display today. Over the next years, my business grew quickly and we were getting a great reputation for quality work. I worked on the tools as a Carpenter for many years as well as doing Sales and managing the business. My company has been registered for over 15 years now and I have trained 3 Carpentry Apprentices so far (it’s good to give back to the system that trained me). We are a family owned and operated business and still operate from Forrestdale. I’ve always taken pride in my work and will only employ quality staff and tradesmen with the same values. I am passionate about building and really enjoy designing and building with modern energy efficient materials. Recently, I have found a way to save thousands of dollars on the cost of building without losing quality, I can now literally save you up to $20,000 on the cost  in Perth!! Come down to my display and see for yourself, I guarantee you will be amazed! So… That’s my story so far… And here is What to expect from us
