Simon We had Hartwell projects carry our our home renovation, this was a front and rear extension and full internal rework, I can honestly say that they were faultless, from the detail that they went into on the quote, to the site set up, then during the job they left the site totally spotless and went above and beyond to ensure that we were happy every step of the way. Above all they delivered the project on time and on budget with no hidden surprises, overall we would highly recommend them - Well done guys Work description: Front & rear extension with internal renovation Project location: West Parley, Dorset Date of work completed: 27 August 2021 - Bruce Woodfield

We move to Poole from Reading. We did not know any builders. Having spoken to a few we decided on Hartwell as they showed more interest then others. We could not of more please both Jon and Josh were very professional and knowledgeable. They accepted change in there stride also offered good advice to accommodate our needs. They completed the build on time. The site was all way clean and tidy. Thank you for turning our house into a home.😀 - Barbara wardman

This was our first building work and after getting a few quotes and meeting some local builders we went with Jon from Hartwell Projects and we really couldn't be happier. Considering the work started about a month before Lockdown for COVID-19 we were very lucky that Jon and Josh could continue the work safely by not knocking through until absolutely necessary and also by going above and beyond to keep the existing roof on our utility room so that we didn't lose use of the washing machine and tumble drier. They were very patient with our two little boys and always great to deal with. The site was always kept tidy and the disruption to both ourselves and our neighbours was kept to a minimum. Communication was always excellent and Jon was very understanding with some of my rather stupid questions that I asked due to being new to this! The extension was completed on budget and in very good time (considering what was/is currently going on in the world) and I wouldn't hesitate to recommend! - Dave Marshall

We delayed progressing our idea for an extension due to fear of the process and risk of choosing the wrong builder. After an initial meeting with Jonathan to discuss our plans and expectations we received a detailed quote with a clear outline of responsibilities and a timeline for each key stage of the work. We also received details of qualifications and trade memberships along with details of previous work. We made our decision – Hartwell Projects it was. Before the work commenced we discussed and agreed rules around site access and safety, especially with Covid in mind and our need to isolate. Progress was quick. The site was always safe, clean and tidy. Jonathan and Josh were always considerate of the neighbours and kept the road and pathways clean and clear. Jonathan did all the liaison with the building inspectors so we were able to watch the build safely. Our initial nervousness was soon a distant memory as the build was completed on time and to the agreed budget. We are delighte - Ken Hunter

Hartwell Projects have recently completed the construction of a single storey dining room extension to an excellent standard. From quotation to completion Hartwell Projects went the extra mile to provide a professional, efficient and helpful service throughout the project. Jon was always more than happy to give advice and suggestions on how to improve aspects of the building and ensure every facet of the works was completed in the best possible way. For the duration of the project I wasn't resident at the property, but I was fully able to trust Jon to efficiently run the site, liaise with building control and stay within schedule. I would fully recommend Hartwell Projects to anybody looking for a truly superior builder! - G.M
