What our client says

I wanted to do a loft conversion and 2 storey side extension but I was so stressed by thinking of dealing with an architect, engineer and contractor after my first experience when I did a single-storey rear extension. I came across SAI Developers and after meeting with them for the first time, I felt so confident and comfortable and appointed SAI Developers to deal with my project from getting planning permission to construction. The best part to appoint a SAI Developer is you only deal with one person throughout your project from getting planning permission, building control submission to construction. I am pleased that with their professional expertise and the way their team manages the project and always available for us whenever we need their expertise. They have managed to get me more space in my loft and rear extension at first-floor level and rearrange my whole house to high standard elegance looking home. The construction process with SAI has always been very pleasant and peaceful and no annoyed or angry neighbours. No extra hidden cost and their after-sale service is an added additional benefit. I always recommend SAI Developer if you want to complete your project without any stress and extra added cost at a later stage.
