Bricklaying- 4 Jun 2020
Brian came a had a look at the wall we needed replacing and provided us with a quote we were happy with. He managed to source all the materials required, though it was more problematic with the current lockdown situation. He and his colleague arrived when agreed, completed the work to a high standard having given plenty of options and choice in terms of brick types etc. They put the rubbish into the skip we had hired and cleaned up after themselves. Job carried out in a socially distanced manner and to a high standard. Would hire again if we need more of this type of work again.

Bricklaying- 20 Oct 2025
Excellent work. The old stone and brick barn required a good level of work to stabilize and repair prior to a new roof being fitted. Nick advised the best and practical way forward. The stone pointing and rebuilding was very good. Removing the existing roof timbers and stabilizing the end walls. Repairs to the brick work and the fitting of the new roof timbers ready for the new slate roof. Green jacket (Nick) were very reliable and commercially very fair. I did not want the cheapest quote, I wanted the most realistic and informed, Nick completed the remit completely. This project will require work to be carried out in different stages and Nick will be called in on several of the following works. Would recommend anyone to use Green Jacket.

Bathroom Fitting- 15 Jul 2023
Andy delivered what he’d promised and exceeded expectations. From first contact in April to completion today (15th July) he has been courteous, professional and has consulted us as necessary as the work has progressed. Problems that were not obvious when he attended site to work up his quotation were all addressed and without exceeding his original quotation. Andy and the tradesmen he uses for work he needs support with are thoroughly reliable. He turned up when he said he would and came back to finish off at a weekend, which was appreciated. We would highly recommend Parnaby Property Developments.

Extensions- 10 Feb 2018
Sean was perfect. Always punctual, polite, conscientious, and willing to do that bit extra to finish the job. His price was very competitive and he always made an effort to work with our timescales. The extension scheme wasn’t a straight forward job, required an engineered slab and temporary support for the accommodation above. Sean tackled it all with ease and got on with the task at hand. Well done.
