All Building Improvements

Our approach

In our experience, there are three things that people want to know when it comes to any construction project:

  1. How much will it cost?
  2. When can you start?
  3. How long will it take?

Everything we do – and the way we do it – revolves around making sure these three questions never become a problem. We give detailed, itemised quotes, and we stick to our timeframes like it’s the most important thing in the world. Because it is!

There’s a fourth one too: quality workmanship. Well, with decades of happy customers behind us, we think we’ve got this one covered. To see our past work firsthand, take a look through our gallery and see what you think!

  • A bit about our company

    Here at All Building Improvements, we’re proud to be a small company. We’re proud to be able to give you a level of personal service that you can rely on from start to finish. And we’re not just saying that – we only work on one job at a time, so you know that when we’re working for you, you have our undivided attention all the way through the project.

    When you choose All Building Improvements, you deal directly with our founder, Denis Knapp, and our close-knit team of tradies. Our whole approach is built on relationships, whether that means our relationships with you, our clients, or with our trusted suppliers and colleagues. In everything we do, we strive to give you top quality for a fair price.

  • What it’s like working with us

    If you’re like most people, building an extension or renovating is a pretty daunting prospect. There’s so much to deal with, from getting council approval to having to check in with the tradies to make sure they’re on track.

    But it doesn’t have to be this way! Sure, if you want to manage the project yourself, we’ll do everything you ask (as long as it passes planning approval!), no questions asked. But if you want to entrust the job to an experienced team that understands project management, council regulations and of course the hands-on art of construction, then leave it to us! You’ll be in safe hands!
    So here’s how the average job usually flows, from start to finish:

    1. Phone or email enquiry

      We’ll chat about the project, asking questions to understand the scope of the project.

    2. Ballpark quote

      We’ll give you a ballpark, based on what you’ve told us. These are usually pretty accurate!

    3. Detailed on-site quote

      If you’re happy with the ballpark quote, we’ll come out and do it properly, giving you an itemised written quote within a week.

    4. Planning/certification approval

      We’ll handle all the paperwork that needs to be done before the job can get rolling. If you already have this, then great!

    5. Work begins

      We only do one job at a time, so we won’t leave until it’s done. You’ll have full access to Denis throughout the job too, so don’t be shy to ask questions!

    6. Work complete

      Once it’s all done, we’ll do a full builder’s clean and walk you through for a final inspection.

    7. After-service

      We guarantee all our workmanship, so if anything doesn’t look right, give us a call and we’ll fix it up. We’re proud to say this never usually happens!

  • A bit about Denis

    Denis has been running businesses in the building industry since the 1970s (that’s well over 35 years!), working on the tools and also as a supervisor and project manager, both directly with clients and as a contractor for some of the country’s big project building firms.

    Over the years Denis has followed his work all the way from Lismore up to Cairns and everywhere in between. He now bases himself in Brisbane’s northern suburbs, and when he’s not on the job you can probably find him taking in a game of footy or cruising out west on his pride and joy, his custom-built trike.
