Extensions- 21 Jun 2017
COWBOYS! Absolute Nightmare! Marius left the job incomplete, after repeatedly demanding more money before completion! Not to be trusted! Workmanship wasn't as good as he would lead you to believe, I have pics & videos of: Cigarette butts in mortar. Bricklaying in the rain, not water-tight roof/felt work, drainage, unsafe electrical work which needs to be redone. Left my neighbour side of roof damaged + with a hole now for a month. Damaged door/table/gate. Of course, he denies any wrongdoing Please be very careful if you have to use this fraud. Get a FULLY detailed itemised quote! Draw up your own contract - do not use his. Do NOT ever pay CASH. Produce a schedule of works - pay him ONLY when the specific task is 100% complete - leaves lots of work unfinished but then lies claiming its complete at interim payments. Get a FIXED price for every aspect of work - do not have "TBC" or ambiguous costs - if he can charge more - he will. Do NOT use his electrician, cringeworthy attempt to "price up" a simple job and damaged roof. Buy ALL Materials yourself OR require receipts for anything he buys. Request ALL Invoices. Ensure he follows specs - offered me £250 off total job cost, if I used a inferior type of rooflight to the one required in spec. Ensure he doesn't keep rubbish on site, Hire a skip. Keep all communication on record, email, text, even voice record him as he is a pathological liar. Very dishonest, delusional and frankly embarrassing.

HEXAFORM CONSTRUCTION LIMITED
Rating: 5 out of 5
Extension Builder in Gerrards Cross
HEXAFORM is a London based multi-disciplinary design and build company that has the experience, work ethic, communication tools, and systems in place needed to bring any scale project from a virtual blueprint to reality. Historically the architect-contractor relationship has been one of an ‘us versus them’ mentality. But we’re 'both'. Having a design team under the same roof as a construction company means that the eccentricities of each project are rendered opportunities, rather than obstacles.

My colleague referred me to Raed who previously have had used R.Hamandi Ltd for construction work and they were very happy with the quality of service. Along with some other building company's last year I also contacted Raed for an estimate. Raed gave us a reasonable price with all the details of proposed work. He also explained about the possible options of how we could get the best value for our money. His professional and friendly advice helped us a lot to understand what exactly we needed and what was best for us to go ahead for our project. We decided to go ahead with R.Hamandi ltd. Raed gave us breakdown of the project and everything was documented. His support in communicating with council and planning related issues was valuable. All the planning permission requirements were followed. Presence of experienced and trust worthy staff including laborers, handymen, carpenters and painters really made it easy for me and family to be around and comfortable while they were working or to leave the house whenever we had to. Raed himself used to visit the site everyday to oversee the progress and used to discuss and take care of any possible issues. Raed's team used to turn up on time and the project was finished on time too. Even after the completion of the project staff at R.Hamandi ltd and Raed himself contacted us few times to find out if we're happy with the work carried out or if we needed any further assistance. Now we have a fully refurbed house with double side extension and loft conversion. Overall amazing service, professional, reliable and trustworthy. I recommend R.Hamandi ltd to everyone for an A+ service. Thanks,

Conversions - General- 22 Nov 2019
My experience with asset construction has been excellent. It was more of a trust thing and Andy was very professional and knew what he was doing. Andy was very honest and competitive as compared to other quotes I have got. I did not have to worry about watching over the builder or being over priced. I can say I can trust on any quotes he gives unlike some other dodgy builders. I had a major job completed by asset construction and will book them for any future work. All his workmen know what they are doing including plasters, plumbers and they do job to perfection. Unlike other builders who rush through jobs to get paid asset construction was more committed in completing the job to perfection even if meant taking longer. Thank you Andy for the great work

Extensions- 8 Dec 2021
Me and my wife are very satisfied with Prabbuilders work. What stands out with Prab builders is that they do every task as if they are doing it for their own house and with work they are meticulous and exceptional. What we started with and how our extension looks now is simply amazing and the way they explain about what will look good(Color/ the structure etc ) is commendable as we both were not sure what decision to make, but after completion we are overjoyed to see how excellent it turned out to be now. I would recommend them anytime based on their skill ,eye for detail, being punctual and the hard-work they invest into every task to make sure we are getting the final product the way we dreamt of.

The job entailed removing decking from the patio area of the rear garden, removing the existing lawn and existing paving path and paved area at rear end of garden. Perry and his team then levelled all the soil and laid a new lawn, new Italian porcelain to the patio area, the pathway and a secondary patio area at the rear of the garden. All the work was carried out in a professional manner, the workmanship was excellent as was the reliability.

We recently completed a full house refurbishment including a 4-metre rear extension, dormer loft conversion, and complete interior renovation with ALMO Property Group—and I genuinely couldn’t recommend them more highly. From the very beginning, the team managed everything seamlessly, from planning and design through to execution. What could have been an incredibly stressful process was made smooth, organised, and surprisingly enjoyable thanks to their professionalism, communication, and attention to detail. The quality of workmanship throughout the project has been exceptional. Every stage was handled with care, precision, and a clear commitment to delivering a high-end finish. The team were reliable, efficient, and always kept us informed, which gave us real peace of mind. A special mention has to go to Ameer, who was absolutely outstanding from start to finish. His dedication, responsiveness, and willingness to go above and beyond made a huge difference. He was always on hand to answer questions, offer solutions, and ensure everything ran perfectly. ALMO Property Group have completely transformed our house into a beautiful home, and we are beyond happy with the results. If you’re looking for a trustworthy, skilled, and professional team, I would highly recommend them.
