Extensions- 2 Nov 2018
Building a 2 storey rear extension and hired Jamal to do the Block work. Initial ground storey heavy Hollow block walls for the 3 x 3m extension completed in only 3.5 days by Jamal himself with no extra help. Hardworking young guy. I was nearly bedbound with sciatica and in great pain and he immediately offered to source and buy on my behalf extra blocks required to relieve further stress on me. Very helpful, reasonable and understanding. Explained anything I asked him diligently. Knows his job and I will be calling him back when I have the money to complete the block work for the 2nd storey.

Works consisted of hip to gable loft conversion under permitted development and a refurbishment of the first floor of a semi-detached house into a four bedroom/bathroom layout, including new windows, balconies, wiring and plumbing as well as sound proofing the walls. With 100m2 of works this was my first introduction to a major building project and I was worried by the horror stories I have heard about builders. From the outset Monika set my mind at rest, listening to what I wanted, making helpful suggestions, offering tips for instance on how to save on the scaffolding and always asking me when choices needed to be made. She took the trouble to ensure that I knew what was happening, with daily photos of progress without the need for me to climb scaffolding. I was working to a tight timescale and budget, which Monika understood, and even having accommodated a number of changes including some additions, the project came in on time and on budget. All of the workers on the site were very professional and the quality of the work and the attention to detail was exceptional. I have no hesitation in recommending Monika and her team - I went into this project apprehensive and not sure what to expect; thanks to Monika, I came out the other side delighted by and looking forward to working with her and her team again to renovate my ground floor.

Bricklaying- 25 May 2022
Top notch builders! We used Future Home Construction to build our large wrapround extension. They are a reliable family-owned company who showed up on time, worked hard, sometimes working 6 days a week including Bank Holidays. The team worked with great care and professionalism and were very informative, walking me through the process and offering me solutions to problems. We have been very impressed with the high standard of work carried out on our house and are delighted with the result. We would recommend Future Home Construction to anyone considering having work done to their house.

Edmond did stellar work on the full kitchen renovation of our central London flat, and I can't recommend him highly enough. His professionalism, expertise, and attention to detail are on another level, and he is an excellent communicator. The end result was meticulous; he worked efficiently within the agreed timelines while resolving unexpected challenges and providing solid guidance throughout the project. Edmond also has a strong network of professionals who were just as reliable and easy to work with as he is. We also appreciated how tidy our home was left every day and how well all areas were protected during the build.

Extensions- 2 May 2018
Tom is a very competent builder, who has attention to details. Tom continuously went out of his way to find ways to meet my requirements, Whenever we had atypical challenge during my extension Tom's default position was "let's find a work around." He was creative and efficient in doing so, and most importantly cost effective, as I was running on tight budget. Fantastic experience working with Tom, he estimated the work to complete in 6 weeks, the work was done 5 and a half weeks and handed over. The works speaks of itself, very urban finish with high level of professionalism. I was almost hands off the project due to work travel, and Tom took care of all the aspects without me being involved day to day and micro manage. He is surely being to be big league builder in no time. I would recommend him whole heartedly.
