What Our Clients Say

GRW made our old house into a fantastic modern and luxury home…

We had a 2-storey front and back extension which involved the entire house layout re-designed – a 6 month build – not one room remained the same.  It was a complex job but the project management from the GRW team ensured they found solutions and communicated options and worked to the timing.

We had bi-weekly budget reconciliations so there were no surprises on spend and savings were often suggested and every element of budget was broken down clearly.

The entire GRW team from Graham and Terry to their electricians, tilers, carpenters and painters were fantastic and they all genuinely cared about the quality of this build and creating an amazing home for us to enjoy. The attention to detail and standard of build was incredible.”

Dear Graham & Terry,
Now that we have had time to get used to the changes to the house, we wanted to let you know how much we appreciate the work that you carried out for us. The standard of workmanship is excellent, and was carried out with care and attention to detail. I feel that you provide a unique combination of skills – Graham with your overall building knowledge, experience and skill, and Terry with your structural and project management expertise. I was impressed with your professional approach and the way that you work with the client to obtain the best solution, especially when unforeseen problems inevitably rear their heads. Your choice of subcontractors was also impressive, using people that share your ethos. You also impressed our neighbours with the clean and tidy site, keeping them informed of what was going on, and minimising the disruption of the work that needed to be carried out on their side of the boundary. I will not hesitate to recommend you anyone contemplating building work.”

Hi Graham & Terry
We would like to take this opportunity to say thank you to you and your team for showing such courtesy and consideration towards ourselves and our neighbours throughout our 8 month building project. Although the project did overrun considerably (largely due to the adverse weather conditions), we were kept well informed throughout and every effort was made to minimise the disruption. We are very happy with the quality of the work which you carried out and would therefore have no hesitation in recommending your company.”
