Pre construction Planning

We will work with you closely at the beginning of your project to make sure that the entire process runs as smoothly as possible. We can provide initial concept drawings through to complete working drawings before we apply for consent from Council. We believe this stage is critical to the overall success of the project.

Project Management

Windsor Construction will manage every aspect of your project while in progress. From demolition and foundations, framing and claddings, right through to interior fit out and exterior landscaping, you can rest easy knowing that our employed carpenters work to the highest quality standards  and we only use trusted sub-contractors that we have built solid relationships with over the years.

About us


Caleb Douglas – Managing Director, Owner and Carpenter

After acquiring his National Certification in Carpentry through the BCITO in his early 20’s, Caleb always dreamed of starting his own building business, which soon became a reality in 2012, after returning from his overseas adventure with his future wife Stacey.

Windsor Construction was born and the rest is history. Caleb has a great passion for all things building related, and prides himself in always going above and beyond for his customers, no matter what the circumstances. 

Caleb realises that the next generation of builders has to be just as strong as the previous, which is why he puts a lot of care and time into his apprentices to make sure that not only are they working to a high quality, but also have the tools and skills to better their own lives and follow their dreams too.

Outside of work, you are most likely to find Caleb spending time with his 3 daughters and wife, as family time is paramount. Sports, fishing and socialising are the next best thing!

 We aim to stick to working within 5km of Eden Park but realise this is not always possible and can be flexible for the right customer. 

Buying a House


Caleb Douglas and his very skilled and professional team built me a new deck and new stairs, an excellent standard of work. The teal over delivered and did a fantastic job for us, beating my expectations at a fair price. I would recommend Windsor Construction to anyone who is looking for any new build or renovation work. They managed the whole project end to end and made it very easy to work with them. Caleb and his team care about the work and take pride in what they do and made the extra effort to ensure I was happy with the end result.

On time, every time. Very high quality. Incredibly nice people. Careful, considerate and very tidy. Knowledgeable. Hard working. They clearly love what they do because they are very good at it. And excellent value. What more could one want? Caleb and his team were a pleasure to deal with. I would use them again in a heartbeat and recommend them highly.



Caleb and the team at Windsor Construction are detail orientated and conscientious builders. Caleb has a deep well of knowledge in all aspects of building and construction. He has patience, high standards and a great deal of integrity. He helped to explain and allay many worries over a complicated deck build. It was great having him and his team on board.

We began our renovation Journey in January 2020. We love our rebuild and as we continue to personalise it to who we are. We are happy and thankful that the time we had spent in our new garage as phase 1 of our build, the 8-9 months was so worth the wait. From the get go you have been nothing but honest, reliable, professional, you and your team work ethic is amazing.

You are all professional, respectful and a hardworking outfit.  I would also like to say that the network of subcontractors you brought with you, also made our build so worthwhile. The Painters, Roofers, Plumbers, Kitchen, Flooring, Tiling.  Hardworking bunch of tradies who deserve thanks from our family as well.  


From our Family, to your team / subbies we are truly grateful and thankful that we have a beautiful warm home.  That our children will be able to love and live in for a long time into their future with their children.

The addition of a conservatory-style veranda and remodel of entrance way, windows and bathroom with a design to extend features of the existing bungalow was my objective and I sought a builder who could be flexible and work with me through the process.

Caleb and Windsor Construction was exactly the team I was hoping for!


He and his team were enthusiastic, embracing the project with full attention to detail and a high standard of workmanship. 

Caleb spent time with me and the decisions we needed to make along the way with an approach that was both genuine and professional, also making it possible to live and work onsite during the build. This combination of approachability and expertise mean’t the work ran smoothly and the whole experience was easier and more enjoyable than I imagined .. which is saying a great deal for an undertaking usually fraught with stress!


The end results are wonderful! I am so pleased with the quality and skill Caleb brought to my vision. 
I would definitely recommend Windsor Construction to anyone considering a build or major remodel and I will use them again for any future dreams I have!
