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!

"Hair Salon Design Set Up. My Project was to set up a hair salon on the first floor of the striking and iconic ‘Sinclair Building’ in Sheffield City Centre. The Sinclair name itself is synonymous with quality, taste and a name ensconced in the history of Sheffield so the quality and finish of the project had to match the quality of the Sinclair’s store. SDP understood this from the start and James Clarke (Managing Director) project managed it personally from day one. The main reason I chose SDP was that I needed a diverse range of trades, joiners, plumbers, electricians, tilers and floor layers and SDP have highly experienced personal in house, who regularly work on “Blue Chip” projects..so I didn’t have to wait for a contractor to “fit me in” between jobs. The other unique factor for using SDP was that they also fabricate designs from stainless steel which was exactly what I wanted, as I needed shelving, sinks and panelling making to bespoke specifications out of metal. Working with James Clarke was an very enjoyable experience and I enjoyed the project immensely..there were no major problems, the project was finished bang on time and with no overspends! I would rate SDP ten out of ten and will be using them for my next shop and all future work on my house. Duncan Gillespie The Cutting Club"

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.

"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."
SUE & PAUL STANDLEY – MILLHOUSES, S7
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.
Sarah Makepeace - Long Line, S11
"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."

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

"After looking around various kitchen design webpages and talking to people, the website for SDP caught our attention because of the bespoke design aspects and the quality of the workmanship. At our initial meeting with James, we were able to explain what it was we were seeking and he was able to advise and make suggestions. This collaborative approach was also taken when we met Steve the kitchen designer. From our first meeting to the completion of the project, continued close communication meant the project ran smoothly and we were aware of what was happening at each stage. James was an excellent project manager, liaising with various trades, electricians, plumbers, plasterers, kitchen fitters, flooring, to ensure the work was done to the agreed timescale and to a high standard and finish. The final result is exactly what we wanted with a few additional ideas from the design team. All of our friends who have visited echo our appreciation of the quality design and workmanship of our new kitchen which we are delighted with. We would highly recommend the work of SDP."

"Renovating a property can be a real minefield at the best of times, fortunately James at SDP was available to make the process as smooth as possible which was critical for me as I was living very remotely from the project. He had all the guys to do the right job in a timely manner and with the minimal of fuss. The finish was very professional and my property was sold above the asking price within a few days of going on the market. I would certainly use him again."
ANDREW HOGG – SHEFFIELD, S10
"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"

"Having decided to finally go ahead with an extension and major redevelopment to our property, we engaged SDP to undertake the work on the basis of recommendation from other people and we are totally happy with the finished product. The work, a full-width single storey extension with, the existing floor-plan being changed from a separate kitchen/dining room into 1 large open-plan living space, was managed by James brilliantly, with every detail of the plans/schedule being made available to us before the work started. James attended almost every day, keeping us informed of expected progress. The team(s) James employs are professional and helpful. A pleasure having SDP do the work and would happily recommend."
RICHARD & LOUISE BOLTON – MILLHOUSES, S7
"I selected SDP to undertake a redevelopment and extension of the rear of the ground floor of my 100 year old semi because James approached the project in a very professional manner, explaining that he supplied a price, not an estimate, he gave a timescale and guaranteed daily visits to my house to project manage the work. There were inevitable little hiccups but nothing that James and I could not discuss and sort out. It was most helpful that James was always on hand so that queries could swiftly be dealt with. Together we could talk through tweaks to the plans. James employs a team of very polite, considerate and caring workers who always treated the house as my home, not as a ‘building site’. As well as this team James also hires in skilled artisans which has resulted in a completed open-plan family room/kitchen/dining room along with a loo and utility room that exceeds my original hopes and plans. I can highly recommend James and his team to anyone considering renovation work, large or small."
ANGELA ANWYL – TOTLEY, S17
"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
"James and his team were a pleasure to deal with. He did some work for my elderly mother. James paid attention to each detail of what she wanted in her bathroom, and his team came in and carried out the work very quickly and efficiently. I would definitely recommend him as a safe and reliable and efficient builder."
MARY LOUISE MORRIS – MILLHOUSES, S7
"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 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
"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"
HILARY – WOODSEATS, S13
"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
"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
