Extensions- 15 Oct 2020
DPS were superb from start to finish. They were hired to build a single storey rear extension in North London including a new kitchen and bathroom fit. I met Ralph on site along with a number of other builders, Ralph was highly knowledgeable and clearly explained what was required with practical solutions. DPS clearly scoped out the timeline and cost for each stage of the build and kept to this. They completed several agreed extras throughout the job. Communication with Ralph and the whole DPS team was first class throughout. I own a number of rental properties and can comfortably say DPS are the best builders I've dealt with, I cannot recommend them highly enough, they will be my first port of call for future work.

I recently used PrimeUK Contractors Limited for conversion works at our studios in Camden, and I couldn’t be happier with the results. The project timeline was set at six weeks, and the team delivered right on schedule. Pavlo and his team had a clear understanding of the scope and what needed to be achieved, going above and beyond to make the project a success. The quality and attention to detail in their work were outstanding, and my entire team was thrilled with the final result. Their pricing was competitive and fair, which was another bonus. When we have more work in the pipeline, Pavlo and PrimeUK will definitely be my first call. Highly recommend!

Latest review:
I received planning permission for a 3m extension, garage conversion and garden office with a toilet/shower and the architect recommended Timall. We of course carried out all our due diligence before selecting Timall as our builder. I received around 8 final quotes from various legal and reputable builders, and gratefully we chose Timall after checking their previous projects. Timall renovated my townhouse, stripped to brick, repartitioned to be more functional for my family, moved bathrooms, new kitchen etc. The council building control said we needed piling for the 3m extension, and Timall were fantastic to change their plans to carry out other internal work whilst a piling specialist was called in, who Timall also liaised with. The garden office, 3m extension and garage conversion all went well. Parminder the director was very hands-on during the project daily, with his builders on-site daily, honest in his advice, and very experienced in his knowledge of the building industry.

I met up with Peter, told him what needed doing and he provided a detailed quote within days. I handed over a set off keys and basically left him and his team to get on with it! This was a time restricted job, he purchased all the material and provided all the receipts. I returned a week later to find the job completed to the highest standard surpassing my expectations.
