Some of Our Client Testimonials
The result has exceeded our expectations. Dave, Steve and Mark are a great team to work with.
They were efficient, professional and experienced what they are doing. This extension to our house has received many compliments and praises from our family and friends.

We are able to sit and look out over the garden and the view that we are blessed with and its been a fabulous party space with easy access to the patio for a real indoor/outdoor experience.

We were guided through the options with stunning sketches of our home and invited to see some real projects to give us inspiration and ideas.

We found Farrow & Jones in a magazine and were almost thinking we would never do anything within our budget.
We called Dave and he got us straight away . Even after preliminary discussions we knew we had found what and who we needed . The whole process was brilliant ,done on time and aftercare has been fabulous.

We couldn’t be more pleased with the end result. The finish is excellent and throughout there is great attention to detail – Dave, Steve and Mark did a fantastic job.

My architect wanted to know who had built it so that he could recommend Farrow & Jones to his clients .
The post sale service has been superb . All in all one very happy client
