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.

Extensions- 4 Jul 2026
We posted our building project on MyBuilder for the construction of a new outbuilding. We received a number of responses and quotes and selected EDSS Ltd. My elderly mother had used EDSS Ltd previously to do a number of renovations to her house and we found EDSS Ltd’s quote competitive and fully broken down. The work completed to date has been high quality with a high level of attention to detail. Stefan and his team managed the project from start to finish. This has included liaising with building control and other parties. We did not have to worry about any detail and Stefan always goes the extra mile to reduce any inconvenience. Stefan and his team were reliable, hardworking, approachable and always willing to discuss any questions we had during the build. The work was completed to a very high standard and we were kept informed throughout the project. We have no reservations in recommending EDSS Ltd and are happy for customers to see the work.

Plastering- 8 Jun 2026
We were thoroughly pleased with Bathroom Renovation, Bahram and the services provided. We required stud walls throughout our apartment, ceiling replacement and ducting/pipework concealing. I can only say that Bahram and his communications have been a breath of fresh air. The team are efficient, friendly and get the job done - most importantly Bahram takes pride in the work his team complete. Our job was relatively urgent and Bahram offered what I feel was a fair price, remained communicative and had his team readily available to get the job completed within the timeframe. Most importantly, as with it seems all building works, jobs can grow slightly, but Bahram’s considered approach and advice was invaluable. We increased the scope of our works mid-job, and are really pleased with the results. Fair pricing, someone who has pride in their work, and a job well done.

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.

Kitchen Fitting- 12 Jul 2026
Ali was brilliant at fitting my tap - it was more complicated than we thought and he stayed longer to make sure it was done, and even came back the next day to fix something that had gone wrong. Mohammad was brilliant, helping me with every enquiry and always answering really quickly, and patiently - super helpful. Overall, excellent - really happy - would definitely hire again.

What qualifications and experience do you have as an extension builder in Waterloo?

An extension builder in Waterloo should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

What experience do you have with similar extensions in Waterloo?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Waterloo extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?
