5 Reasons Why People Choose Us

One builder from start to finish

You deal directly with one builder throughout the project. That means clear answers, straightforward communication and full accountability from the first conversation to final handover. 

Selective projects, not volume building

TOHL Homes only takes on a limited number of suitable projects at any one time, so your extension receives the time, oversight and care it deserves. 

Clear communication at every stage

You are kept in the loop from planning through completion, with regular updates and weekly site visits during the build. 

Detailed fixed price clarity

Once the design, scope and selections are clear, you receive a detailed fixed price contract so you know what is included before work begins. 

Quality without overpromising

We never overpromise and underdeliver. Every extension is completed to a standard we would be proud to put into our own home. 

Sign your house extension or addition contract and receive a complimentary

professional interior design consultation and selections package. You will also receive a detailed fixed price contract with no hidden surprises, plus a priority construction start date for your project.

Process 

Step

Initial conversation and project fit

We discuss your ideas, goals and what you want your Adelaide house extension to achieve.

Step

Concept, design and planning 

Planning, preliminary engineering and selections are coordinated early so the design, scope and budget align before building starts. 

Step

Estimate and fixed price contract 

Once the plans and selections are clear, you receive an estimate and then a detailed fixed price contract based on the agreed scope and finishes. 

Step

Approvals and pre-start 

After the contract is signed, approvals and remaining selections are finalised before work begins on site. 

Step

Build with clear communication 

You stay informed with regular updates and weekly site visits so you always know what has been completed and what comes next. 

Step

Completion and aftercare 

You walk through the finished extension, raise anything that needs attention, and receive a maintenance period along with standard structural warranty coverage. 

Hear From Our Happy Customers! 

We engaged Tohl Homes to do our extension and we are beyond happy with the result. The workmanship is excellent and the communication was great. It was a big undertaking, our ideas were discussed, understood and brought to life in a timely manner and we were always kept in the loop. The quality of work really shows and having lived in the extension for over a year, it is clear that care was taken, it was built to last and no corners were cut. Thank you for building our dream family home! 

Amy Goodwin

We couldn’t be happier with our experience building with Harry Tohl and Tohl Homes. From the very beginning, nothing was ever too much trouble. Harry consistently went the extra mile to make sure every detail was just right and finished to the highest standard.



The result was a home with high-end, luxury finishes that exceeded our expectations. Whether you're planning a renovation, an extension, or a completely new build, Harry is someone you can trust to deliver quality work with care and integrity.



Building a home is one of the biggest investments you’ll ever make, and choosing the right builder is crucial — we’re so glad we chose Harry. His calm, professional approach made the process smooth and stress-free. He’s a clear communicator, a great problem solver, and genuinely fair and honest.



We’ll absolutely be using Tohl Homes for any future projects. Thank you again, Harry!
