  • Loft conversion in terraced house in Weoley Castle

    Dave is a trustworthy, friendly person. He went out of his way to help us and produced an excellent design for the loft conversion. He solved a lot of problems when doing the design. He was on time when visiting and on time producing the plans.His wife Pauline was always quick to answer by email. An efficient team! The price he charged was very competitive and I would definitely use him again and recommend him to friends.

  • Creating plans for single story rear extension

    We decided to go with Dave after meeting 5 different architects and definitely made the right decision. We've never had any work done to a property before but Dave put us at ease and took our ideas & pointed us in the right direction, using his expertise to come up with plans for our extension that fit our needs brilliantly. Even when we decided to make a few changes to the plan, nothing was too much trouble and he was happy to help.
    We've since recommended Dave to friends who are having a loft conversion as we know he will do a great job. Thanks for all your help Dave!

  • Two storey extention

    Not very happy with the work Dave did for us.
    Poorly advised our plans and misled what we could achieve on our site.
    Was late for meetings
    Gave us a list of services that he would provide for the payment we made and took payment in full a didn't deliver said services IE full detailed drawings and calculations for beams and foundations.
    The drawings that he did provide were addressed wrong and to be honest overall very unhelpful in the whole process.

    DJ Building Design's reply:

    I am very sorry that Alan was so dissatisfied as the last thing I want is dissatisfied customers. I completed 97 jobs last year with no other complaints.
    I advised that there may be an issue with parking and I contacted the planning department for pre-application advice because I was concerned . They said it would be better to apply and have the proposal judged on its merits. I informed Alan of this before I proceeded but he was happy to go ahead.
    it would have been pointless giving him the calculations and details for an extension which would not be built. The drawings did however include a full specification, a section and details of the foundations, walls and roof
