    Our Process

    We work with our customers and take all needs into account to ensure the perfect outcome. Whether you are just exploring the possibilities available to you or you already have designs and plans, we can take your project from concept to reality.

    When you work with us on your project, you’ll always know exactly how it is progressing. We work methodically, ensuring all parts of the process are taken care of and you are kept in the loop.

    Our process has been designed to be as easy and stress-free as possible for you, our customer:

    • Initial concept – we carry out a survey at your property to see what is required and find out the scope of your project. Tell us about any ideas you have – no matter how dramatic! During this stage, we will work with you to map out your requirements and understand what we are trying to achieve.
    • Estimate -our estimator will assess the work required and put together a full quotation. Take your time to look through it and ask us any questions. We never use any pressure selling techniques – take as long as you like.
    • Refining concept – we will now look into the finer details of the plan to ensure that each and every detail is covered and you are completely happy.
    • Design and planning – working with our partner architects, we will put your ideas onto paper and then submit this to your Local Authority, should this be needed. We will also prepare a full schedule of works so that you know what to expect at all times.
    • Project – a dedicated project manager will be on hand to see your project through to completion.

    By working with one company, you are in greater control of the process. You’ll know exactly who is carrying out the work, as we only use our in-house building contractors, making us fully accountable for quality control. You’ll be able to get hold of us if you need to – your dedicated project manager will be on site and our head office support staff can assist with any queries.

    Just call 02079247303 or email for any information you need.
