Ground floor back extension, reconfiguration and full redecoration. We chose Dali, firstly through recommendations by neighbours, seeing his work first hand and feeling confident during the consultation phases of his ability to deliver. Prior to the job commencing a schedule of works and costing were clearly agreed. We were impressed with Dali's level of communication and his availability to meet with us personally. He would always return a message promptly and that continued throughout the job. Dali expertly guided us through the project and also arranged architect and structural drawings, site surveys, council applications and 3rd party wall advice. We decided to live-in during the build which is never ideal but Dali cordoned off spaces for us to live whilst allowing him to get on with the job. He set up temporary kitchen and laundry facility some 3 or 4 times for us! Now for the business end. Dali supervised the project but also allocated a Manager, Michal to be our point person and he was on site every day without fail. Both would respond to any question promptly and courteously. I learnt to keep the questions short and be more patient as the job progressed as everything was always on their agenda to be done. Teams of builders would arrive punctually by 8am and work would always start promptly. Everyone on the team had clear instructions and their industry was on show from start to finish. I could not fault them at all for their reliability and professionalism. They were all courteous, polite and respectful and would also make a point to clear up after themselves at the end of each day. On occasions I did request a deviation it was fully discussed so we could make informed decisions but nothing, no matter how small, was made to seem trivial as they were intent on delivering an unquestionable product. The job progressed sometimes at lightning pace with crews of builders coordinated daily and we hardly had a single day where someone was not in attendance. Dali would continue with a regular update by email or phone so we were always aware of progress. When problems did occur, Dali and Michal would distress those situations, find solutions quickly and sometimes you are oblivious to there even being a problem. On the few occasions they made mistakes they were not argued about but swiftly rectified ... finding someone who was honest and proud of their workmanship has been a true find. The work progressed to schedule and the end result is something we are not only thrilled about but cannot fault at all. It is a level of workmanship we have been truly delighted with. Another thing I am confident of is that if something does happen in the future Dali will respond to my call whether it be now or in a year's time. There is so much positive to be said and I would highly recommend DPS Ltd for their professionalism, reliability and workmanship so much so I have already asked them to continue on the 1st floor.

I had a joiner to install a WRENS kitchen. After 3 days and a fair sum of money paid, almost nothing was done and on looking what was done was very poor quality workmanship which had to taken back out. Jack was recommended and in fairness could have walked away with the mess that was left he took it on . Jack was in attendance when he told us he would be and was very diligent and detailed in his work and he kept us informed of any challenges he foresaw . He showed me see that there are still good quality tradesmen who take pride in what they do.

Roofing (Pitched)- 10 Oct 2025
Contacted me very quickly. Came to view the issues, quoted me a price and I accepted. The job was completed the same day! Both chaps were lovely, polite and I am very happy with the work. The most outstanding thing was they were tidy and cleaned up after themselves which is something of a novelty here. Obviously there has been no rain fall but I was told that it is water tight so no more leaks. Excellent service, thank you.

★★★★★ Highly Recommended! I had an existing 3-bedroom rundown property and contacted multiple builders before meeting Director Mr. Q Nawaz. From our first meeting, I was impressed by his ideas and the fact that Grand Designs could provide all services in-house. Initially, I proceeded only with the planning application to see if what he promised was possible—and YES, he delivered! My application was approved as he assured me. Seeing this success, I entrusted them with the entire construction project, and Grand Designs completed it within just 6 months, despite the challenges of COVID-19. Not only did they build my project, but they also added significant value to the development. I’m proud to have worked with them, and their exceptional work on my St Albans development is now featured in their portfolio. Within one year, the value of my property increased by £500,000—a testament to their expertise! Extremely professional, highly skilled, and very reasonably priced. You don’t need to go anywhere else—Grand Designs is the complete package!

FAQ: Your questions about loft conversions answered

What should I expect from a loft conversion company?

A specialist loft conversion company will handle the process from design through to completion. This includes providing detailed plans, dealing with planning permission or permitted development checks, ensuring structural safety (including joist strengthening and fire safety compliance), and managing all trades involved. You should expect transparent pricing, a clear schedule, and full adherence to Building Regulations.

Do loft conversion companies need insurance?

Yes. They should hold public liability insurance to cover property damage or injury, and employer’s liability insurance if they have a team. Companies offering design or structural services should also have professional indemnity insurance.

What questions should I ask before hiring a loft conversion company?

Ask whether they’ve completed similar conversions in properties like yours especially if it’s an older or listed building. Check who will manage planning applications and building control, what their typical timelines are, and whether they offer a fixed or itemised quote. It’s also useful to confirm how they handle unforeseen costs, subcontractors, and any aftercare once the project is complete.

Do I need planning permission for a loft conversion?

Not always. Many loft conversions fall under permitted development rights, especially dormer and rooflight-style conversions, provided they meet specific volume and set-back rules. However, if your home is in a conservation area, or you’re altering the roofline significantly, planning permission is usually required. A good company will guide you through the permissions process from start to finish.

How long does a loft conversion usually take?

The timeline of your loft conversion will vary lots depending on the size and type of conversion. A straightforward Velux or rooflight loft conversion can take around 4 - 6 weeks, while a dormer or mansard conversion may take 8 - 10 weeks or more. A loft conversion company should provide a clear schedule tailored to your design and property.
