About
A lifelong passion for architecture and building
Diamond and Lambert Builders (DNL) have long been regarded as one of the most experienced builders on Sydney’s North Shore and Northern Beaches.
Michael Lambert and David Lambert feel fortunate to have been business partners of a special kind – father and son who share a passion for building, architecture and family.
Michael completed his apprenticeship as a boat builder in the early 1970s for a leading Sydney company, absorbing the ethos of fine craftsmanship and establishing DNL with John Diamond in 1975.
Michael’s son, David, completed his apprenticeship with a leading building company in 1989 and became site foreman. He subsequently studied to become a qualified builder and, after the retirement of John Diamond, joined his father in business in 2010.
Over the last 30 years David has built new houses and renovated older ones, making him well versed in all areas of the construction industry. His passion is residential work, undertaking both large and small building projects and consistently fulfilling his clients’ dreams across the North Shore and Northern Beaches of Sydney.
David has since taken over the running of the business, and feels very fortunate to have someone with Michael’s experience continuing to be available. DNL continues to deliver the same personalised, genuine service that has been provided in the past and that the business has become known for over the last 45 years.
Diamond and Lambert Builders are members of the Master Builders Association and the Housing Industry Association.

Our clients say
Leanne B, St Ives
Once we understood the professionalism that the D&L team were bringing to our renovation, we requested to increase the scope to a much larger renovation and, as with everything, David was very accommodating.
Throughout the renovation D&L ensured that every detail was attended to with care and thoroughness. Our renovation presented some unique challenges, but the team completed the job with a smile, constant communication and always to our very high standard.
Marie C, Neutral Bay
David is a builder par excellence. His passion for achieving the very best for his clients is one of the reasons he was strongly recommended to us by friends. From conception to completion of our renovations, David was impeccable in his approach to service delivery. He is a builder of the highest integrity and brought to our renovation projects a team of highly skilled tradespeople who were true professionals in their fields.
We highly recommend David Lambert of Diamond and Lambert to anyone seeking to engage a builder with commitment, professionalism and integrity.

We are very pleased with the job undertaken by Diamond & Lambert Builders. The house looks so much better and it was completed with minimum fuss, in expected time frame and with no mess. Thank you very much and many thanks to everyone involved.
Liz & Pete, Lane Cove
We consider ourselves very fortunate to have found David and his team at Diamond and Lambert Builders. David takes our dreams as his own and works his build around it to realise what we are attempting to achieve. It needs to be significantly noted that the people David has working for him are outstanding. David’s innovation, experience, and quality workmanship has meant that challenges resulting from incorporating the old with the new have gone without a hitch. We would highly recommend that before you make your choice of builder speak with David first! You won’t regret it.
