This was a project that we was asked to be involved with after the original building contractors shall we say never carried out the works as a professional construction company, as I’ve said before you must do your research on the company that you intend to use on your projects, more and more this is happening and it’s no fun and it’s horrendously expensive to pay twice, you have been warned, stay safe and up the professionals, PS big thanks to all the guys involved in this project, Respect x

In order for a dream project to be created you must go with the correct construction company, many times I’ve had to put other builders work right as the clients have been taken on and the original company have created a nightmare situation, please make sure you pick your construction company wisely, Steve
