Large job, internal building work (altering wall positions) and redesigning/refurbishing of two bathrooms in very old cottage. Well planned, managed and delivered. High quality and beautiful finish, work delivered to cost and scope (very slightly delayed due to additional reinforcements required to floors). Very pleased and would recommend.

Extensions- 23 May 2022
Ceca Developments have done an outstanding work on our side and rear extension project, and we would definitely recommend this company. Firstly, they have offered a really competitive quote for the work and have been very transparent and detailed in regards to how long it will take to complete the project. Sebastjan has been a pleasure to deal with and was very helpful during the project, providing honest and useful recommendations and being available every time we needed anything. All the work has been completed to a very high standard and to the agreed timelines. We did not have to worry about anything during the whole project, which made this a very pleasant experience.

Daniel quoted comprehensively and clearly for both jobs that I needed, building an extension and a raised patio at the end of the garden. He worked extremely hard and diligently every day. Also he would summarise what he would do next and we discussed any changes etc and which tiles or render I preferred. I am very happy with both the patio and extension and Daniel finished everything off to an excellent standard and went above and beyond the quote. I would not hesitate to use him again and recommend him highly.
