Daniel did several jobs for my wife and I. He rebuilt a custom internal fitted wardrobe including new lager doors. Built and fitted some custom storage behind our bedroom door. Installed some shelving in our airing cupboard. Built an Installed a custom shelf in our second bedroom and a few other smaller jobs like fixing doors and handles. He was very thorough and professional from the moment he came to look at the works to the moment he completed them. We're supper happy with the quality and with his communication throughout. I've had several houses in different counties using many tradesmen over the years and I'd have no problem recommending Daniel to anyone.

Fantastic job constructing a side extension to create a new front door and hallway, and blocking up the existing door. Theo worked efficiently, and worked with us through a few 'design changes' along the way - without any complaint. Many thanks Theo - we're absolutely delighted with your work.

Extensions- 8 Oct 2025
Jason and his team have just completed our wraparound extension, and the result has exceeded all expectations. Their workmanship, accuracy, and attention to detail are outstanding, and the whole process was smooth and stress-free. They stuck to timings, kept the budget in mind, and made everything feel effortless. Partway through the build, Jason had to undergo an operation and was signed off for five weeks. Remarkably, nothing was delayed — his team carried the project seamlessly, and with Jason still on site when he was able to be, everything ran perfectly. It’s a real credit to how capable they all are and the consistently high standards they work to. The only negative thing I can say is that we were sad to see them leave – they’ve been such a positive part of our daily lives over the past eight weeks. The finish is exceptional and we’re absolutely over the moon. We couldn’t recommend Jason and his team highly enough.

Bricklaying- 31 Oct 2019
Nic, did a super job. The finish detailing of the brick wall connections look great. He went above and beyond in regard to making sure he did what I wanted, each step of the way, and didn’t assume anything. He tidied up afterwards, helped with getting materials sorted, offered to drive unused materials back to the builders yard for me, turned up on time, and was pleasant and friendly to have around. I would highly recommend him to anyone.

Job was the removal of old, and installation of a new back garden gate and fence. Our house is end of terrace with a public path leading behind and down the side of the house, so security is a concern. Great initial discussion, with Niall helping us narrow down the best options and making sure we were happy. Workmanship, professionalism and reliability were all excellent and we're really happy with the final outcome. I would highly recommend Niall and 101 Construction & Landscaping, and will definitely be giving him a call again in the future.
