“We were very pleased that we made John our builder of choice for a large conservatory replacement with a Garden Room & Loggia. The professional and enthusiastic attention to detail combined with pragmatic advice and ideas when interpreting the architect’s plans. This came together over many months to a superb finished job.
The daily work planning and activity was first class with excellent time keeping, communication and tidiness on site and management of external contractors as part of his team over many months.
John and team’s refreshing positive ‘can do’ attitude was a pleasure to work with resulting in a finished project of super quality to be proud of.
We have no hesitation in using Gullaksen Developments on any of our future projects and we can especially recommend them for that very special building project of the highest possible quality; a company to trust.”

— Mr & Mrs Dron, Whitton
We had an extension, garden room and new kitchen built by John and his team. Not an easy job, as it involved widening openings, and building in a garden with little access to the front of the house for machinery, so everything had to be dug by hand, carried in and out by wheelbarrow etc.

We were very glad to be able to put everything in John’s hands. He dealt with window and door manufacturers and the kitchen and tile suppliers, and efficiently brought in tilers, plasterers and so on as and when required. He took a great design but tweaked it to be as effective and practical as possible and also always took into account the aesthetic effect. He dealt with the big items (the build) all the way to tiny details (outside lights and taps, shelves and so on). The work was finished to a very high standard – a great job, done with the minimum of fuss and mess. John even set one of us up temporary kitchen accommodation during the works, while the other spent the time abroad, watching progress by Skype!

“I am delighted with the restaurant conversion that John designed for us. From concept to execution John’s involvement was professional and thorough with great attention to detail. He brought the project in under budget and we will certainly use his services again when required.”
— Gary Dunn, Director of The Pie Pub Company Ltd
“From start to finish the standard of work and professionalism in every aspect of our build has been outstanding. John and his team have far exceeded our expectations. The attention to detail, commitment and enthusiasm has been exemplary.”
— Mr & Mrs Buckle, Ferriby
“After meeting with three different builders we decided to go with our gut instinct. John Gullaksen came across as honest hardworking, and full of enthusiasm. As we have had lots of experience in renovations we wanted a builder we could work well with. Throughout the building process John had great project management skills and the job went smoother than any other work we had done in the past. He finished the work on time and we have loved everything we have set out to achieve. We personally feel that we wouldn’t have got there without the input of John and his team. Professional on all levels, and always at the other end of the phone when needed.”
— Mr & Mrs Fisher, Hessle
“We couldn’t have been happier with the building on our house, all completely project managed by Gullaksen Developments. From the initial building work through to the final finishing touches, Gullaksen Developments handheld us through the decisions we were required to make, offering valuable advice and guidance at all times.

With us never having embarked on anything like this before, we relied heavily on John’s planning and management to deliver the programme of work on time and within budget. With our property being an old Victorian house, there were many challenges throughout that made the renovations relatively complex at times. However, John’s flexible approach and “can do” attitude meant we were able to change decisions as we went along, which took the pressure out of us having to decide everything at the start, before we were able to visualise how it might look.
Ultimately, what we found to be utterly priceless was the scheduling and management of the high quality tradesman. John’s quest for perfection at all times meant we were able to rely on the work getting done to the very highest standard. Having experienced the comfort of Gullaksen Developments overseeing the renovation process end-to-end, we would not attempt to do further work to our house without engaging them again.”
