  • Wonderful Job

    10Verified Review

    We had Cso construction come to our home to build an extension on our property. From start to finish they did an amazing job. The guys were so friendly, professional and were brilliant with our children when they were asking them what they were doing ! Couldn’t recommend enough and will use them again for any future projects we have

  • Single storey side extension, new skylight installation, and built-in cupboards

    10Verified Review

    Connor and his team were great, and we'll absolutely be calling him again if we need anything! All his guys were clean and tidy and super nice, it never felt like there was any friction. He handled everything, including all the scheduling and dealing with building control. We really appreciated how good he was at updating us on progress, giving a rough outline of what was happening when - we work from home, so knowing which days were going to be particularly noisy allowed us to plan accordingly - and he was always great at communication responding to our questions, requests, and tweaks.

  • Removal of vertical supporting beams; conversion of garage into 2 rooms; refitting kitchen

    9.75Verified Review

    Connor and his team of contractors have done a brilliant job of renovating our house, starting last Nov with the removal of 2 structural supporting beams, then converting the garage into a utility room and games room, and finally refitting the kitchen and tiling the kitchen/dining room floors. He is efficient, hard working, easy to work with. His team of contractors (plumber, electricians, plasterers, tilers etc) all did a great job as well. Thanks for turning our house into a beautiful and comfortable home!

  • Two storey rear extension

    10Verified Review

    This is the third time we have had CSO Construction to carry out works. This time they carried out a two storey extension, giving us more living space and a much need extra bedroom. Throughout the build we were kept informed of what was going on and what work were coming up. This was especially important when it came to noisy work as there was young children around. All the work was completed to a very high standard and we are thrilled with the out come. CSO have done a grand job on the house and we will not hesitate to use them again for future work.

    So pleased with my new dressing room and en-suite. Looks amazing and the team were excellent. Connor has a real eye for detail and finish which reflects in the end result. Would absolutely recommend them

  • Kitchen refit and removal of load bearing wall

    10Verified Review

    From start to finish Connor and his team were fantastic! I have used them in the past and am so pleased I had them back to fit my new kitchen. I also had a load bearing wall removed as well as a new walk in pantry installed and throughout Connor gave good advice and had some brilliant ideas which I hadn’t thought about! The team were always punctual, tidy and polite and made the extremely stressful experience of a new kitchen installation much much easier! Connor even set me up a temporary sink in my garage just so I had somewhere to wash up! I would highly recommend Connor and his team.
