As an RIBA Chartered Architecture practice we have worked with many contractors over the years. We have been absolutely delighted with the quality and service provided by Triangle Construction on two recently completed house refurbishment projects. Both involved the modification and total upgrade of a whole house, including complex structural steel installations, new services and new finishes throughout, but both finished on time and on budget, to an excellent quality of finish with impressive attention to detail. Altin, Esmeralda and the team were attentive and easy to work with. We will definitely be proposing them to our clients again… we only wish we had discovered Triangle Construction sooner!" - Fiona

Excellent experience. Altin delivered to time, cost and quality. 100% recommend Altin and his team to others for all renovations or building works. Happy to offer reference visits to any potential clients. Our house required a full internal renovation with extension work. We had a local architect draw up plans and obtain permitted development approval. We were introduced to Altin via a colleague and also spoke to other clients, and saw his work first hand. Of the 4 builders we got to quote, Altin was the one who gave us the most confidence that he could deliver to the cost, quality and time we wanted. This proved to be the case. This was a relative stress-free experience. The project took 5 months once work commenced. This included Altin accommodating a few changes to the design and some extra work. He quoted for this in advance with rates that were fair and reasonable. Altin's background as a qualified engineer shone through in his ability to identify issues and recommend options. One example was the roof design which was not fully detailed in our plans. Altin proposed an option and commissioned a structural engineer to draw up the plans. His experience of working on houses of this age was also invaluable. He was prepared for problems with damp, poor foundations and uneven floors. The level of professionalism shone through in all aspects of the work. From the initial introduction to the neighbours to the final decoration and finishings. Altin is very hands on which commands the respect of his team and his customers. We decided to avoid the cost of a project manager / architect so took on the responsibility of working directly with Altin. This ensured quick decision making and probably contributed to the short completion time. Altin was very good at communicating progress and laying out when decisions were required. As long as you have the knowledge and time to do this, I would recommend it. - Andy

"In both experiences (2010 and 2018/19), the work has been delivered to the high standards expected, and within 5 and 1/2 months as planned. Any extra structural work necessary, that was unplanned has been flagged in advance, was discussed and agreed together for it to be reflected in the overall budget. From a cost perspective, certainly not the cheapest but quality which is fundamental in delivering structure is essential and well worth paying for. The building site, was safely covered, to limit disrupting to the neighbouring properties, with the adeguate roof temporary covering and scaffolding sheets. There are cowboys out there that simply don't care about neighbours or quality. Altin team is the exact opposite. Altin Ndoni himself, in charge, is a highly experienced and trained civil engineer that goes well beyond simple execution, working in close collaboration with the architect and structural designers to ensure the best for the project. Solid structural work is delivered to high standards of professionalism by all his crew, tidy, clean, patient, quiet and smiley people. A real pleasure to work with closely. Praised by both neighbours. It did require quite a hands-on role from my side, which I thoroughly enjoy. the carpenter team went beyond the routines job with some bespoke joinery and carpentery that was decided along the way. Good kitchen fitting skills as well. good plumbing and electric teams." - Elena

"We first used Altin and his team from Triangle Construction in 2014, after strong recommendation and seeing some of his work, to complete a loft conversion and refurbishment to the upper floors of our house. We were extremely happy with the results and were confident that he would be our contractor of choice for the second stage of our project. Triangle Construction recently completed major works to the ground floor of our Victorian house, incorporating structural glazing to create a contemporary kitchen, utility and w.c and refurbishment of the living area and garden. Altin and his team are immensely hard working, honest, reliable and efficient with tremendous pride in their work. We cannot fault them and would use them again without hesitation." - Roksana

We employed Triangle Construction to build our dream home. We received several quotes from local builders, as it was a large, complicated project and even if Triangle was not the cheapest, we do not regret our decision. Altin’s qualifications on structural engineering and his experience in construction, reassured us that they were the right team to take on the build. Altin dealt with other companies (Thames Water, National Grid, BT etc ,as it was a new build and it needed services connected) in a very professional manner, updating us weekly about the progress of the work. He was patient, polite and considerate. He kept to the time given and there were no unexpected costs involved. The quality of the finish is excellent. The house is truly beautiful. I highly recommend Triangle Construction. - E.Q

"Our full refurbishment was a 9 month project and had the potential to be a complete money pit! However, this Company took time with the quote, respected our budget and astounded us by coming in on budget and ahead of time. The men were a joy to work with and regardless of whether the owner was on site or not, remained motivated and courteous. I have never experienced such a work ethic and the speed that they worked at was phenominal. My home is located on a busy road so we were expecting rather a lot of grumpy neighbours but if issues did arise, they were calmed quickly and without fuss. My neighbours said the builders couldn''t have been better (and one of them is a builder!!). I believe we found a rare quality with Triangle Construction which was the ability to take full responsibility for the finished product and the personality to keep things calm with us, the suppliers, the neighbours and your tradesmen. We are looking forward to our first Christmas this year in our new home that Triangle Construction helped us create and I shall be in touch early next year with regard to some more work in the basement.

We hired Altin (Triangle Construction) to renovate our 3-bed house and to extend two-storey to the side, back and into the loft to create a 6 bedroom, 3.5 bathroom house. We decided to write a lengthy review, as we believe it is important to recognize good reliable trades people. We found Triangle Construction (led by Altin Ndoni) on the Federation of Master Builders (FMB) website. We interviewed Altin and a number of other builders and felt Altin to be genuine. Having found Altin's quote to be within the middle of the range of quotes received and given his membership of the FMB we decided to go ahead. We were very pleased with the outcome and would highlight the following experiences: - The quote given was the final price asked for and paid and there were no additional hidden costs. Payments were always in arrears and only invoiced in the knowledge that we were satisfied with the work being done. - The work was completed within the time frame discussed. Altin also then came back afterwards to do the snagging. Altin accommodated a longer time-frame for the snagging as we had recently welcomed a baby into the family and wanted to settle down a bit before further work was done. - Altin's team was professional, polite and courteous with us and our neighbours, which soothed some of the inherent challenges of doing work on a semi-detached property - As in any construction work, unforeseen events and other issues did crop up. Altin dealt with these very well - discussing with us the options before going ahead. - Perhaps most importantly for us, Altin was always reachable and available for us when we needed him. Both my wife and I worked in the city and so needed to meet in early mornings or during weekends. Ultimately, Altin and the team did a great job and my wife and I are very pleased with the outcome and would highly recommend him. - Eugene

"We recently had the pleasure of appointing Triangle Construction as our contractors for our loft conversion, ground floor rear extension, under floor heating and associated renovation works. We are simply amazed at the quality of the workmanship produced and we highly recommend him and all his team at Triangle Construction. Altin's extensive knowledge of building works and his background degree in Engineering,shone through the project assisting us with some excellent practical solutions. Indeed, from our initial consultation with Triangle Construction to the near completion of the build, we have been delighted with every aspect of the process. Altin and all of his team were flexible, approachable, polite, conscientious, tidy, courteous and considerate. We have completed similar projects in the past with other contractors but we can genuinely say that Triangle Construction are the best ones. We will without a doubt use Triangle Construction again in the future and would strongly and highly recommend them to anyone!" - Andy and Dina

"We cannot recommend Triangle Construction highly enough. I first thought to ask for a quote because I had been passing one of their sites on my walk to work, a pretty extensive side extension and total reworking of the existing build, and noted how the workers always were respectful of passers by during works, pausing to let them past and acknowledging them (and the works of course looked very well done and were being progressed diligently). Ours was a loft extension, which necessitated similar sensitivity, in that we remained living at our property during works. Triangle's personnel at every level were always considerate, hard working and talented at their jobs. Altin, the [Director] of Triangle is everything anyone concerned about builders needs to put their minds at ease. He is quietly confident, unflappable no matter what the challenge, clearly experienced and full of practical solutions, always taking what you have to say seriously. Altin has a top team and manages them well between Triangle's various jobs. Triangle's sensitivity to close urban redevelopment considerations was brilliant. My neighbour commented on many occasions that he has never seen such tidy builders, with the tools and materials at the front of my property always kept in good order and debris removed as it accumulated. We are delighted with the results. The utility of every part of our loft and the stairs has been maximised and everyone from visitors to the neighbour's party wall surveyor had said how great it looks, seamless with the existing build. The loft looks light and open during the day and at night; the bathroom a pleasure to experience. We would certainly use Triangle again. - Sheridan

We have recently finished a complete refurbishment of our house. We would like to thank Altin and his team for the fantastic job they did. The standard and quality of their work was very high with a great attention to detail. Altin is very reliable and wants to do the best possible job. The whole team was extremely considerate, helpful, polite, tidy and hard working. Many of our neighbours commented on how nice they were! We have recommended Altin to other friends and would highly recommend him to anyone who is planning to have work done on their house. We will not hesitate to use Altin and his team again in the future. Maria and Edoardo, Teddington. - Eduardo
