His attention to detail, quality of workmanship and professionalism is truly outstanding.  Errol you are a master of your trade and you have the vision and the ability to turn your clients dreams into reality.

We are ecstatic with the luxury finishes, flexible open plan and the smart home automation.  You have thought of everything and built us one of the best modern contemporary terraces in Balmain.  We will forever be grateful to you.

The renovation of my 180 year old terrace was completed on schedule and true to quote, to my complete satisfaction and delight.  Errol has to be commended for his outstanding work.  As a builder, he is a perfectionist, paying thorough attention to every detail.  Errol is also a gifted artisan and I was indeed fortunate to have been guided by his creative vision.

I was particularly impressed with Errol’s professional advice throughout the work.  His recommendations worked out fantastic and it would have cost me a lot of money had I employed the services of an interior decorator.  Due to Errol’s competence in organising and managing his team, there were no delays in the building process, everything flowed smoothly. Errol has the unique ability to combine dedication and tradesmanship with creativity and great taste.

After meeting with quite a few builders, we employed the services of Oscar Development to carry out the office fitting of our head office located at North Ryde.  Errol and his team were most professional and I would like to congratulate them on a superb job and say that it was handled in the most expeditious, and thoroughly professional manner.

Errol’s work and reliability is of the highest standard, one which left us extremely satisfied and impressed.  We were delighted with his pleasant manner and his competence in his work is extremely commendable.

Right from the beginning, we were impressed with Errol’s reliability, efficiency, honesty and friendliness.  Once the work was completed, his workmanship was of the highest level and pricing was also very competitive with no surprise extras 

Errol was always knowledgeable and helpful with design suggestions and very pleasant and communicative at all times during the entire process.  The work started and finished according to schedule and any minor problems encountered along the way were handled and solved with equal effectiveness.

We are extremely happy and impressed with the renovation of our house in Rozelle carried out by Oscar Development.  The work was finished both on time and of the highest quality with excellent attention to detail.  The fixtures, fittings and materials used are excellent.  Errol kept us fully informed of progress at all times and although we deviated from some of the original plans at times, he was always happy to oblige.

Oscar Development completed a major exterior and interior painting and decorating project for our Company’s new NSW showroom and office facility.  We were most impressed with his reliability, attentiveness and quality of work.

Our company is very selective in this regard, and we require all suppliers to share in our own high quality philosophy.  We are delighted with the results from this contract and very appreciate of Errol’s work for our company.

I am writing to express my gratitude on the excellent service Oscar Development has provided me with the renovation of my recently purchased property at Petersham.  As you know, I had very little time but you were able to take on the challenge and complete the house in the allotted time.  

You also gave me great advice on colours and assistance on other jobs and contributed to making my change of residence surprisingly trouble-free and untraumatic for which I am very grateful.

We found Errol and his team to be hard working, friendly, honest and very professional tradesmen.  The renovations they did for your Kindergarten were finished before the estimated time.  This also included doing many extra jobs that arouse during the renovation time.  We found the workmanship to be of a high standard and would not hesitate to recommend Oscar Development to anyone considering any type of building work.
