Extensions- 30 Jan 2020
We cannot thank Danny and Constructek enough for our beautiful extension. From his first visit to look at the project and quote through to the last this week to complete Danny and his team have been amazing. All of the trades people were so friendly and accommodating. Danny handled all of the tradespeople and deliveries for us, making the whole process such a job. The standard of his work is beyond exceptional and it is clear why he is a Master Builder. Nothing is too much trouble and Danny accommodated our every request. He and his team made our project a joy to have built. We really cannot recommend his company enough. We would be more than happy for any of his potential customers to come to our home and see the exceptional work they have done. We are over the moon with our finished project and will be using Danny and Constructek again. Thank you so very much more making our dream a reality.

James provided a fair quote and delivered the project within the agreed budget. He kept the communication channel opened all the time, with constant updates about the progress and next steps so we knew exactly what to expect across the whole project. He was reachable through Whatsapp and happy to answer all our queries. He delivered a good quality job and we are very happy with the outcome as he managed the whole project including dealing with building control. I’d highly recommend him.

Elliot and Paul did a great job of designing and building our garden wall with step and pillar (12m x ~90cm). They worked solidly over several days, reliably arriving early every morning despite the distance and cleaning up effectively. Elliot was exceptionally responsive and approachable. I can thoroughly recommend this business based on the work done and how it was carried out.

Extensions- 27 Apr 2026
We enquired about a front porch installation and were impressed to receive a prompt response from Ascension Property Developments & Construction. From the outset, they were responsive, professional and easy to communicate with. After scheduling a call, they took the time to clearly and thoroughly explain the entire process, answering all of our questions and ensuring we felt confident moving forward. They were also very accommodating with scheduling, arranging for the work to begin while we were on annual leave, which made things incredibly convenient for us. Once the project started, the team worked efficiently and kept us informed every step of the way. They even set up a group chat to provide daily updates and create a space where we could easily ask questions or raise any concerns. This level of communication made a big difference and gave us real peace of mind throughout the entire process. The end result is fantastic and our new porch looks beautiful!

My wife and I cannot begin to say how happy we are with our experience with LNB Building solutions LTD. Builder/Owner Lokesh was amazing and went out of his way to assist us through the building process. Before deciding on LNB we met many builders and took quotes from 8-10. Lokesh gave us a reasonable quote which was within our budget. The primary reason for us to go with Lokesh, was his passion and the guidance he gave us during our initial conversations. Also working on a project like this, we need to be able to build a good working relationship with the builder and we felt it could be done with Lokesh and I am glad to tell we were right! One of the best things about Lokesh is he is a very trustworthy and transparent person. He tries to save you money wherever he can i.e cost in terms of second fixtures that we were supposed to buy. He advises on the best places to buy stuff and tries to pass on maximum discount via his trade account. Also would like to take this opportunity to give a big THANK YOU to everyone involved in the project especially to the core team which included Jodha, Gagan, Naveen and Luv Singh, who were part of project through out from Day 1 until last day. The project was delivered within the agreed timelines. All our family and friends who have seen the house cannot believe what we have achieved. Thank you to Lokesh and his team for building us our dream home!!

Carpentry- 19 Jun 2019
The job actually got bigger as the time went on, once I’d removed the old wardrobes the walls needed plastering and the laminate flooring needed extending, so a “simple boxing in job” became a nightmare! Dan’s professional approach was unquestionably and his ability to be able to fulfil all of the requirements was brilliant. The room and surrounding area was left immaculate at the end of each day and he was always prompt arriving in the morning. The finish of the work was 1st class and I can’t recommend him enough, if any one would like to see his work, then their more than welcome to view.

Our job was a completion of a front wall that had been damaged. Matthew understood our wall design helped with a decision for space for a gate. Visited a couple of times with brick types to ensure we liked the finished look. Job was completed in time frame suggested and if any changes in days it was communicated. Very professional, great price, tidy and polite. Very pleased with work. Would definitely recommend.

Charles and his team did a brilliant job on my double garage extension. Start to finish Charles and his team were really polite and clean workers. Charles was always in contact with me and giving me updates daily and always kept me in the loop at every stage. Project was completed to a really high standard, a very reasonable price and in good time! It wasn’t the easiest build due to a water leak from Thames water nearby causing a mud pool but it was still completed in a great time frame! I can highly recommend them for any works!
