Company overview

At Cassilis, we’ve used 30 years of quality, boutique home building experience to refine a simple philosophy: we believe that the time taken to get your home built right is time well spent.

Today, everyone is in a rush to have things done ‘yesterday’. To us though, there’s no greater frustration than construction delays caused by poor planning, unrealistic quoting, and communication breakdowns between suppliers, tradespeople and builders.

Our strategy is to get involved from the ground up, connecting you with quality architects, suppliers and tradespeople who we know will suit your needs, and who we know will be as passionate about your project as you are.

We truly appreciate the importance of time in busy lives – that’s exactly why we guarantee we’ll never waste yours.

Starting out in domestic construction as a carpenter over 30 years ago, David quickly learnt that his passion for building lay as much in the personal relationships formed through his work as it did in expert craftsmanship.As testament to this, he now boasts an enviable network of long standing clients, architects, suppliers and tradespeople. The strength and continuity of these relationships truly reflects the time and hard work he has put into building and maintaining them over time.

Today, he is proud to include in his portfolio everything from top end luxury homes to smaller scale renovations; from the straightforward, to the weird and truly wonderful.

Whatever the job, what you can be sure of is that David will always be there for you, every step of the way:

What clients get with me is an extremely personal service. I’ll hold their hands from beginning to end and beyond, and they’ll always have access to me. I build every house as if it was my own.

– David Alexandrakis.
