Extension Builder in South Hampstead
I started working in construction sites as cleaner back in 2005 and then joined a company that was carrying out commercial renovation for licenced premises, listed buildings and offices and then moved to other companies that were carrying out domestic works, such as loft conversions, extension, renovation and everything in between. I would like to think of our company as a 1 stop shop to all your construction needs, from planning to costing, from project managing to building and delivering.

Restoration & Refurbishment- 28 Apr 2024
I highly recommend these people if you want to be fleeced, taken advantage of, treated appallingly and work left unfinished. The standard of work is below average. If you want high quality finishing do not come here. I’ve had to spend a lot to redo a lot of their mistakes and mess. If Jerzy could charge you for every single nail he would, so beware. And when you challenge, they get aggressive and nasty. Very unprofessional. Do yourself a favour and keep away. So thanks Jerzy and co for a load of stress and rubbish. I am happy to talk to anyone and advise against these people.

Tiling- 21 Jun 2021
Great professional and reliable service from Easy Solution. Waqar called me ASAP and arranged to see my bathroom. He came within 1 hour to see the job and gave me an affordable and good quote. He was available to start work immediately. Waqar also suggested the colour of tiles that would suit the bathroom and made some very good recommendations on where i could purchase them at a decent price. My work was done to a high standards. Tiles are neatly put together with grout and they are looking amazing! I had some many relatives comment on them and i have recommended Waqar to them all as i was so satisfied with his service and professionalism in my property. I will be using him always in future. Thanks.

Extensions- 15 Jul 2019
Norbert and his team have transformed our house to the most amazing standard, we would recommend them to all our friends and family. The work schedule was managed so well, with minimal disruption to us with two young boys. We had a loft conversion, main bathroom renovation, utility room, downstairs toilet and a 4 meter kitchen extension. We stayed in the house whilst the work was being completed and Norbert and his team fitted in so well, it actually feels weird not seeing them in the house. They are such a lovely bunch of people. We are over the moon… on time, on budget and finished to a high standard. If we ever undertake renovation work again, Norbert and his team would be our 1st call!

What experience do you have with similar extensions in South Hampstead?

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 South Hampstead extension builder’s ability to deliver a result that meets your expectations.
