We take an open-minded approach to each project.  Tangible constraints will influence the make-up of a project to some extent, however construction is the marriage of good design with human endeavour & attention to detail. We insure each homes perfection using our extensive checklist ensuring only the finest quality construction during the building process.

From 2008 to date he has built a number of high-end Mediterranean & Contemporary style villas and completed a number of large refurb projects of villas.

Frank is on the construction site most days, he is intimately involved in the construction of each home. He recognises that building a luxury home requires great patience, deliberation, and communication. He believes that a home should be a journey/partnership between the builder and the homeowner.


“Diamond Construction did a fantastic job refurbishing our 1970’s Villa. For years the prospect of renovating completely overwhelmed us and we simply did not know where to start, luckily friends of ours recommended Diamond Construction. As crazy as this may sound - The entire process was actually enjoyable. Frank & Gustavo were able to translate our vision and créate a open plan space that is a pure joy to be in, making the absolute best of what we already had. We are extremely pleased with the final result and have no hesitation in recommending the Diamond Team.
