"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."

"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."

"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."

"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"

"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 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
"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
"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
"The company has recently fitted me a new kitchen, the quality of service and workmanship has far exceeded my expectations, I had prepared myself for a chaotic 11 days !! 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. Good job lads! Kind Regards, Susie Coish"

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.

"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."

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

"From the start SDP were professional and filled me with confidence about the standard of their work. James was friendly and helpful in getting exactly what needed doing sorted and timely in all his responses throughout the project. The on site workmen were friendly, reliable, helpful and did a fantastic job. I am really happy with the standard of the work and would recommend them to anyone. My house looks exponentially better than it did as a result. Kind Regards, Adam Wood"
ADAM WOOD – HILLSBOROUGH, S6
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!

"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
We engaged SDP to build a single storey kitchen/dining extension which they completed in April 2017. The project was managed very effectively by James and the team, to ensure completion within projected timescales, to budget and without any compromise on quality. Without exception we were impressed with the competence of all the tradespeople engaged on the build and their helpful approach to resolving any issues which arose. We are very pleased with the finished product and wouldn't hesitate to recommend SDP.
David Howarth – Bents Green, S11
"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 would like to say that I only have praise for the team that completed my insulation work in my roof/attic. All work was completed within the specified time and on budget with a friendly manner, James was on site to check all work was on schedule every day. Cleaned up after themselves everyday & was polite punctual. I would recommend them to anyone."
MRS NUNN – MALIN BRIDGE, S6
"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 !!"
NATALIE & ADAM – SHEFFIELD, S20
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.
