"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"

"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"

"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
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!
Emma Sheehan – Stannington
"Thank you very much for all at SDP Ltd who have recently refitted our kitchen and carried out building works to make our kitchen and dining room open plan. The work was carried out to a really high standard and all of the workmen who attended our house were friendly and professional and left the house tidy once they had finished each day. The work they have carried out is fantastic and we are really glad that we instructed SDP to carry out the works which were all organised for us from start to finish. Thanks James. Lindsay"
LINDSAY COATES – RIDGEWAY, S12
"When we first thought about having the house extension built, I expected to be fulfilling the role of project manager, organising the trades and resources etc. But when the quote came in from SDP, which included James’ performing that task, it seemed a much more sensible idea to leave it to him given the differences in our relative experiences of the building trade (I had none). James did as he’d promised and turned up almost every day he had workmen here, making sure they were doing what they were expected to and that they had the resources they needed. He also kept us well informed about what to expect next. He’d provided a complete plan and timescale (which was perhaps a bit ambitious) at the start, and as is the case with many builds, things sometimes happened beyond our control that impacted the completion date. But James was always happy, willing and able to work around the delays, revising and rescheduling as required. Throughout the whole build James and his team have always been friendly, honest and polite, and have often contributed ideas and suggestions for making the build better, more professional and more effective. Now the build is finished, we’re delighted, as we have a new kitchen, garage and workshop that get’s a ‘Wow!’ from everyone who sees them. We are happy to recommend SDP and would have no hesitation in using them again."
ANDY TIMMONS – SOUTHALL, S20
"We found Sheffield Properties Development efficient, effective and value for money. James kept us informed of who was coming and when. He also solved any problems that occurred there and then. We didn’t have to wait long for answers or solutions. His teams did a good job and were reliable, personable and hard working. Our new extension is a delight and it’s almost impossible to tell that it is new brickwork from the front of the bungalow. We are planning to do our kitchen next year and will be using this firm again. Regards Christine"
CHRISTINE FERRIS – TODWICK, S26
"I bought my house a few months ago and needed some work doing. I have never heard about SDP and when I did meet them they gave my a very professional service. James listened to me and was very passionate about the project as just as me. I am delighted with the work that he has done already and look forward for him to work for me in the future. Thanks James. Christine"
CHRISTINE DALEY – TOTLEY, S17
"Thank you very much to Sheffield development properties. Recently we had our brickwork cleaned and re-pointed and I could not be happier. I had tried with many attempts to clean the brickwork around my front door and was having no success so I rang James at SDP to come and give me a quote for the pointing, while he was there he recommended having the brickwork sandblasted and what a great idea it was, the price was very good and the results are fantastic. Couldn’t be more happier with the finished result. Thanks very much James , I will not hesitate to call you in the future. Kind Regards, Callum and Cat."
CALLUM BATES – GREENHILL, S8
"We contacted James after a recommendation from someone who had used SDP previously. We were looking to replace our kitchen and create some extra space via the removal of some adjoining walls. James and Steve were extremely helpful in terms of proposing different options, whilst always looking to meet our requirements. The final layout has meant much more than just a new kitchen. We feel like the rear of the house has been completely revamped, giving us a more airy, spacious, functional and modern kitchen / dining / entertaining space. Having also added some additional work to our roofed conservatory (underfloor heating, bi-fold doors and seamless flooring), like many of the other testimonials on this site, we too are receiving lots of ‘wows’ from visitors. A small extension to the front doorway was also carried out by SDP – this was also done to a high standard and has left us with a far more practical space. We would certainly recommend James and his team – who were all extremely helpful and friendly. As our children grow up and we seek some additional refuge, I’m sure we will be back in touch re a loft conversion !!"

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.
Mary and John Wilde
Highly recommended. Used James and his team for a rebuild of an extension. The team were so professional, on site every day. The coordination of all the trades was seamless and the work was to a very high standard. Great communication, everything cleared away well, the building secured and weekly payments so you only pay for the work completed that week. Would definitely use SDP again.

"We have recently moved house and decided to knock through a couple of walls to make a larger kitchen diner. Initially we contacted about 5 other companies but for one reason or another they were not interested or didn’t turn up. I felt like I was coming to the end of my tether with it all, then I saw one of the Sheffield Development Property Vans; I made a note of the name and sent James a text. He arrived when he said he would, he helped us plan the space and dealt with the building inspector. What a refreshing change! The work started when he said it would ( almost to the minute ) and the guys who turned up worked in a very professional manner, they did not stop, not even for a break! They really did put in a sterling effort! Am I happy with SDP? Yes, I am delighted. Thank you James, Paul, and Guntis! Thanks again James"
ANGIE CLEMSON – SHEFFIELD, S8
We had a fantastic experience with SDP. James and his team knocked through our lounge and kitchen last year, this involved obtaining structural engineer's calculations, knocking through the brickwork, putting in steel support then arranging building regulation sign off. This was finished by 'making good' including plumbing a new radiator, re tiling the floor and re plastering. The work was carried out to the highest standard and from start to finish the process was smooth. What really impressed me was how specific James and his team were with the timeline of events and when they would occur so we could adequately plan ahead and his team are really friendly. We are already planning on using SDP again when we extend our kitchen later this year. I cannot recommend them highly enough!
Michael Parry – Dore
"Hi James, Many thanks for these fantastic photos. They do indeed look brilliant. It really does put my amateur efforts in to place but on the other hand they show our home in the most wonderful way. Let us also take this opportunity to thank you and your team. We are absolutely delighted with what you and your guys have done. You have helped us realise our vision for our dream house. From the outset we were confident that you would be able to deliver what we wanted, on schedule and within budget. The format of payments was excellent. We really appreciated your “can do” attitude and the way we were able to add items into the schedule as we realised that we needed to do more to our house to make it into our home. The finished quality of what you have done is wonderful. Your guys have been a pleasure to work with and we thank you for the care that they took working in our home. Also, watching your guys tackling some of the more ‘difficult’ tasks was truly exciting. Working through the development of the project, day by day with you on site, has been a pleasure , your attention and sense of humour have ensured that it has been a really great build. We have really enjoyed our time with you and your guys and want to thank you all so much for building our dream. We are so pleased and delighted that everyone who walks in goes WOW! Best regards, Jim & Adrienne"

"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
"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"
LIZZY & IAN ATKINS – CROOKES, S10
"We contacted SDP to do a house inspection for us prior to buying our first house. James was very helpful in taking us through the potential works identified in our Home Buyers report and associated costs and risks. Once the house purchase was complete we took up SDP’s offer to undertake some works to the timber in our cellar. The work was completed in a professional manner and to a high standard and SDP could not be beaten on price by the other companies that we considered. Overall we were very pleased and will definitely consider SDP for future works. Kind Regards, Andy & Liz."
ANDY & LIZ, BRINCLIFFE, S11
SDP recently completed our loft conversion, from start to finish they were superb! James and the team were incredibly open minded and friendly, they listened to all of our requirements. They kept us up to date with all progress and any amendments / changes which were required they offered options along with the pro / cons to each choice. Each day we were made aware of what they were doing and progress which had been made. They ensured the site was tidy and clean after each visit, which was important as we had to live in the house during the conversion. The finish was amazing and we would highly recommend them to anyone doing any building work. Absolute pleasure and we will always look to use them in the future.
James Wilson – Old Tupton, Chesterfield
"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."
