With over 25 years of experience SDP are a property developer with a difference. We know homes are more than just bricks and mortar, it’s about enlightened design, enhancing lifestyles and we are proud of our building work throughout Sheffield. We see ourselves as a regeneration company. We’re not just here to rip it up and start again. We revive buildings with a consideration for the past, present and the future.
There are a number of ways in which you can increase the size of your property, but none offer quite the level of scope that you get with an extension. Dependent on the amount of land that you have at your disposal, an extension presents you with the capability to increase your home substantially, making it into a living space that benefits your exact specifications.
When it comes to creating additional space in your home, opting for a loft conversion can be the most cost-effective way of doing so. The loft conversion process involves utilising a building’s existing roofing structure, which means a drastic reduction in costs, particularly when compared to some of the other conversion/extension alternatives out there. If you are looking to maximize space for a minimal outlay, then a loft conversion could well be your best option.
"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 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"
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
"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."
"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."
"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."
"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 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 !!"
"Dear James, Just wanted to say thank you for the work undertaken on our property , the work was done well and to schedule. The workmen were helpful and cleared the work area on completion, be assured we will contact you in the future to quote for other work. Many thanks John Ramsden"
We love our new kitchen extension. It is exactly what we wanted. SDP listened to exactly what we were after and did a fantastic job. Everyone who worked on it was very friendly and polite and worked to high standards. I would definitely recommend them.
"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."
"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"
"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"
"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."
"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 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."
"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."
"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"
"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"
"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."
