"James did some major work for me and exceeded my expectation. They where limited disruption and his workers where fantastic. Thank you SDP for building my dream room! Christine Daley"

"The small bedroom in our house required a complete refurbishment, including re-plastering, new electrics, re-siting of the boiler and the installation of wardrobe/cupboard space. We approached SDP as, when looking for potential builders, we came across their website, which seemed very professional. James responded promptly and came to meet with us to discuss our requirements. He was receptive to our thinking, listened carefully and offered good advice. We received the estimate within two days of meeting James. James arranged for the various workmen to visit prior to commencing their part of the work, where this was necessary and scope what needed to be done. When the work commenced James project-managed each aspect and visited each day while the work was ongoing. He also responded promptly to any telephone or text messages from us. We are very happy with the end result and the way this was achieved. Any unforeseen difficulties were resolved quickly by James in a professional and reassuring manner. Keith and Hilary"

"Dear James I just wanted to thank you and your team for a great job carried out on my property. I felt that your quote was fair and that I was kept up to date with proceedings and felt included in decisions to be made during the project. I also felt that your team were timely, polite and clean, taking care to clean up after themselves. I particularly liked the fact that you managed the project bringing in tradesmen when required to ensure minimal wasted time and that you finished on time and in budget. Thankyou for a job well done and I wish you the best for you and your team. Jamie Denholm"

"After hearing good things, I contracted James and his team to do some considerable refurbishment work on one of my student terrace houses. The property needed a full loft conversion, a refurb of the main bathroom, bedroom, and dining room, and a totally new kitchen. Not only that – but with it being a student property we only had the small window of the summer holidays to get everything looking tip top again in time for the new academic year. It was a tall order but the job was completed to highest standard and with complete efficiency from the whole team at SDP. I couldn’t be happier with the work. Everything was completed on schedule, and with total transparency from James about where we were at, at every stage. Because of the terms and conditions drawn up in advance, I knew the exact schedule of works. Payment was spread across the duration of the project and there were no hidden costs. SDP also sourced the kitchen themselves, using my specifications – which was a massive weight off my shoulders. The team were always punctual and polite. All in all, I couldn’t recommend them highly enough."
TONY DOUBLEDAY – HILLSBOROUGH, S6
We heard about James and SDP through a recommendation, so arranged what was a very friendly and informative meeting. We received a quote from him that was good value and comparable to other quotes received. We chose James because the finishes on the pictures on his website certainly looked impressive, and for the personal touch that was already apparent. This was also true of Steve, who designed the kitchen, and who was equally friendly and full of ideas. Nothing was too much trouble throughout the project, which was completed quickly and in a highly efficient way. We were in very regular contact with James, who was incredibly accommodating of anything we asked, and offered plenty of good suggestions, always looking to minimise costs as well as deliver a quality product. An example of this was a suggestion to alter the original design to incorporate a goalpost steel and remove a large pillar – something we didn’t think was feasible. He did this despite additional pressures on his team’s schedule, and kept costs down as much as possible. The end result was phenomenal - and hugely appreciated - transforming the space into a stunning kitchen diner that has wowed everyone who has visited since. Throughout the project, we were kept completely informed of timescales and what was happening next, and this was all done with a great degree of humour – the relationship developed between us and his team into a really close one. All of the numerous guys who worked on our extension were friendly, polite, clean and highly skilled. The end result has transformed our lives. It’s the first extension we’ve had done, and we were full of trepidation, but the whole experience was far less stressful than we imagined it would be; a major factor in this was that way that everything was managed via James as our main point of contact (although the various workmen were equally accommodating whenever we asked anything of them). All in all, I would highly recommend James and SDP. It’ll be the bathrooms next! Cheers bud Matt

"Our long awaited extension is so impressive and looks amazing. Everyone who comes to the house and sees it, always gives the same reaction – Wow! James and his team were incredibly helpful throughout the whole process. At one point we wanted to amend a section of the build, James worked with us to make sure we got the result we wanted and the finished result was definitely worth it. The extended area has given us much more space and light and creates a wonderful relaxing environment which is perfect for a family with teenagers. We would highly recommend James for any building project , his approach is professional and he looks after his customers well, we will always return to his company for anything we may need in the future."

"We’ve used SDP twice now, and both times we’ve been delighted with the results. The staff are friendly, polite, and most importantly, they deliver an excellent standard of work. We HIGHLY recommend them. Joe and Kayti Ball"

"We were immediately impressed by SDP, because, unlike many similar businesses, there is a project manager, James Clarke, who liaises directly with clients and tradesmen. We felt safe in instructing this company to work for us, because we knew that we could go back to James if there were any problems. However, the job couldn’t have been slicker. The workmen turned up punctually and completed the work on time. They were friendly, polite and caused minimal disruption. I am registered blind and they were sensitive to this throughout, letting me know when and where to be more cautious when moving around in areas where they were working. After the work was complete, James phoned us to check whether we were happy with the work, prior to invoicing us. When I queried one issue which we were unsure about, he came out especially to inspect and ensured me that there was nothing to worry about. We now have a lovely new pavement outside our house; not only is it a bit more flood-proof, but much to our cleaner’s delight, is easier to sweep. My husband and I are currently in the process of requesting quotations for further work by SDP. It doesn’t seem to matter what job needs doing; they have all types of tradesmen: plumbers, carpenters, joiners, decorators, electricians, damp-proof specialists, roofers and people to do other outside work. No more scrolling through endless lists of tradesmen in the Yellow Pages and wondering who is trustworthy. We’ll go to SDP every time. Kind Regards, Sarah Byran."
SARAH BYRAN – HILLSBOROUGH, S6
"James did a great job project-managing the refurbishment to our apartment, especially considering I was based out of London and unable to regularly check on progress in-person. His past experience was evident in all the design tips he shared (and implemented) to prep the flat for a quick sale. Finally, and most importantly, the realistic timelines which were very much appreciated in order to keep the project on track. Thanks, James!"

We decided that as we were getting older a downstairs toilet would be beneficial. This would be built in the rear of our integral garage. With the front of the garage being extended, with new roof, to allow the continued garaging of our car. Getting planning permission took about 7 weeks. I felt that at least 3 quotations would be required. I had listed our requirements as detailed as possible and identified 3 builders, two local and the third, SDP, I found from a web search. Although SDP were not the lowest quote, we both felt that the way James, the Managing Director dealt with us, was impressive. We went to SDP office to discuss and sign the contract. I had thought of a few queries and tweaks which James accommodated without issue. He also advised us of suppliers they used, for us to choose some of the fitments etc. We were advised of a probable start date and probable duration of the work. Although there was some slippage it did not affect us. The basic building work was done by the team of Ian and his mate Richard. James was on site early most mornings, checking progress and ordering the materials as required. I had not really fully anticipated the level of work required, with lots of sand, bricks, aggregate, timber, and two skips etc. The weather was not always good but it never stopped Ian and Richard, although they were very wet on occasions. Cups of tea seemed to work wonders. James was open to my suggestions and queries although he did suggest on one occasion that I had ‘too much time to think’! Anyway most were accommodated where possible. All the tradesmen were also very professional and competent. Tidying up as they went along. Overall we were happy with the work; in particular the way Ian built false doors to the garage extension for security and in our hallway which really kept dust and disturbance to a minimum. He also built replacement shelves to the rear of the garage. Pricewise I was a little concerned, due to my suggestions and tweaks but it came in ‘on quote’ apart from a couple of items which we asked to be changed. James certainly seems to keep his several active projects, small and large, going with very little impact on ours. We would thoroughly recommend DPS and wish James and his team best wishes for the future.

"We first met James when we went to view a house he refurbished on Cobnar Road, Woodseats. We liked him and were so impressed with the work his team had done that we didn’t need to think twice about who to call when we wanted an extension on the back of our house. James was on hand with help and advice from the very beginning right through to completion of the project. He introduced us to Ahmed, his architect (Nada Architects), who drew up some great plans for us and dealt with the planning permission. Once the building work began, James visited nearly every day to make sure everything was going well. His team of workmen were extremely hard working and polite. They arrived on time and at the end of each day they tidied up before leaving. Their work was of a very high standard, as we knew it would be. It was a pleasure having the whole SDP team around. We are absolutely delighted with our new extension and it has significantly improved the quality of our living space. It is modern and tasteful and integrates well with the rest of the house. It looks attractive from the outside as well as on the inside. We can recommend James and his team, without hesitation, for any building or refurbishment work. They are competitively priced without compromising on quality. It is good to know that we can call on someone we trust when we need more work doing in the future."
JULIA NEWTON – BRINCLIFFE, S11
"As new house owners, we had no experience of having work done on property. James and his team made the entire process simple and easy, working with extreme professionalism, to schedule and on budget. Even our requests for custom wardrobes and awkward tiling didn’t phase them! We are overjoyed with the results, and will seek out SDP next time we need work done. Thanks again, and send out regards especially to Gundas! Lizzy and Ian"

We had been considering having a kitchen /diner extension for a number of years, hoping to make more efficient use of our home. We first met James two years before our project started, and after consultations with other builders felt that we would like him to do the job. We had James architect Ahmed to draw up the plans for us, he achieved just what we had asked for a room filled with lots of natural light and views onto the garden. The team started on a bank holiday Monday which was a nice surprise to us All of James team from the bricklayers, labourers to electricians were hardworking polite and friendly guys. After spending many weekends looking at kitchens we met Steve Wake the kitchen designer who works with James. He listened to our ideas and eventually came up with a beautiful fitted kitchen for us and managed to design us a corner larder cupboard to optimise our space. We couldn't decide on a colour, luckily Steve gave us right up until the final minute of production to decide. A problem we did have was trying to arrange time to see James as we were both at work and James wasn't available of an evening. However he came to the site each day to see how things were progressing. We now have just what we had dreamed off and everyone who sees it as to how it was before is very impressed. Thank you to James and his team.

James and his team have just recently completed renovation work on our new home. The house was extremely dated, so required a new kitchen, new bathroom, as well as a lot of other work (knocking down a wall, moving an existing wall, changing a cupboard to a doorway, new boiler, changing a door to a window, installing French doors, removing a porch, new front door). From start to finish, the installation was seamless and completely stress free. On top of this, the work was completed on time! James organised all of the work to be completed by day, and managed the entire project. James put us in contact with Steve, the kitchen designer who listened to every aspect of our needs, and created a bespoke kitchen. Cannot rate this team highly enough - they are trustworthy, reliable, completes the work to the highest standard, and is constantly on standby to answer any questions. The house was always left clean and tidy. Overall, we are so impressed with the quality of the work, we will undoubtedly be having SPD back to complete further work on the house. Thanks so much!

"James, We would just like to say thanks to you and your team for completing the alterations on time and to budget . You kept us informed throughout , the work was to a high standard and the various tradesmen turned up when you said they would. We were very appreciative of the fact that your tidied up after themselves and kept the disruption down to a minimum. Once again, many thanks Michael &Sandra Totley , Sheffield"

"I purchased my house at Beauchief from james six months ago. James showed me the property when it was partly renovated and I fell in love with it. He has sympathetically renovated the house keeping all the lovely features. All the bathroom and kitchen fittings are of a very high standard and since moving in I have not had any problems. I am over the moon with the house and would not hesitate to buy from James again and indeed a couple of my friends are interested in purchasing off him. Thanks, Philippa."
PHILIPPA DIGNAM – BEAUCHIEF, S8
"I needed some basement work completed as it was determined that after a surveyor had looked at it, there would need to be a full rebuild of the wall. The guys who came round were friendly, hard working and did an excellent job. They tidied the place up nicely after the work had been completed. Extremely happy with the cost for doing it and would not hesitate to ask for future work to be completed by Sheffield Development Properties."
JOHN DANIELS – MILLHOUSES, S7
"We recently used SDP to relocate our bathroom and the other rooms on our first floor. From the initial visit to the end of the build they understood what we wanted and worked with us to achieve it. They removed the existing bathroom and completely relocated it, including all fitting and plumbing, a new wall, doorway, skirting boards, and skimming the walls in the process. They protected the carpets throughout the work and tidied at the end of each day. They had great attention to detail and the tiling in the bathroom looks fantastic. The final invoice was very reasonable and we would definitely recommend them again. Rob and Lucy"
ROB & LUCY HURRELL – MEERSBROOK, S8

In fact the whole job was a stress free experience, workmen came and went, only bothering me if really important . They kept mess to an absolute minimum, clearing up at the end of each day, they were also polite and courteous .All in all I can t recommend sheffield development properties highly enough.
