Extensions- 11 Feb 2022
We had to wait a few months before Rick and Lee could start, as their previous job overran. However, we're so glad we did! From start to finish they were an absolute joy to work with. Nothing was too much trouble for them and they always advised us the best way to go about things. They are a definite credit to the trade. The job is now complete and we're just waiting for the sign off from the Council. We can't recommend Skyline Southern enough. If you find Rick is booked up, that's because he's in high demand, for obvious reasons. My advice is be patient and wait, it will definitely be worth it in the end. Thank you Rick and Lee for a fantastic job!

Restoration & Refurbishment- 11 Sep 2022
My partner and I couldn't be more thrilled with the service and standard of workmanship that Matt and his team have achieved on our recent first floor conversion. The quality of the finish is fantastic and I would have no hesitation in recommending him to family and friends. Throughout the whole build communication was brilliant and at no point did Matt or Tony ever assume or make any decisions without consultation or checking in. Problems and solutions were worked through jointly and nothing was every to much trouble especially as the scope of what we originally asked for grew as the build went on. This was driven by us adding items to the original brief. They were really helpful with recommending showrooms and suppliers which made the decision making process streamlined. We were lucky to move out for the build but everyday our home was kept clean and tidy. Finally all snagging has been dealt with promptly and it's lovely to see that the company is also striving for a high standard of finish. Thanks very much for everything.

Extensions- 18 Dec 2021
Louis and team completed a front of house single story extension, installing 2 steal beams, making good and transformed our house. The workmanship was to a very high level and he came up with a few ideas which we added to the design. Louis is incredibly tidy and often goes further than any builder I’ve seen to keep the space safe and clean. We love our new space and cannot wait to put it to good use.

Extensions- 1 Sep 2025
Ben, Ian and his team did a brilliant job. They came across a few issues this was due to the building plans they had to work from (architectural designer did a disappearing act). This didn’t faze them at all and kept me informed of how they would solve these concerns. They always arrived on time and constantly consulted with me as to how I wanted things to look. The whole extension consisting of a new kitchen and shower/toilet room couldn’t have turned out out any better. They have since completed a few other jobs one being a seating area (completed just from a picture I showed them) with cupboard storage. Again really pleased with the results. Pictures show during and after

Landscaping- 27 Mar 2026
Couldn’t have asked for a better service and quality of workmanship. Quote was fair and Macaulay explained everything in detail that he could do and made reasonable recommendations. The work completed was beyond my expectations and they went over and above, even clearing additional bits I had already gathered together. Everything was made immaculate afterwards. At the end of the job, he explained how to keep the lawn healthy and care tips. Couldn’t recommend them enough. Thanks for everything guys!
