Frequently Asked Questions

Taking on a loft conversion or home extension project can be daunting task. We strive to make sure that your project is a success by taking as much of the stress out of it as possible. We have therefore created some FAQs to help you along the way.

  • Why are you so much cheaper than some other providers are?

    Some providers, including architects, charge as much as four times more. Because we specialise in lofts and extensions, we can complete more quality projects in the same amount of time.

  • How quickly from when I engage your services until we can submit drawings to the council?

    Allow up to one week for the survey and then a further two weeks for draft drawings to be prepared. We then build in a further week for any amendments before submitting them to the local authority.  The total time is four weeks from instruction.

  • Will I need to get my own structural engineer?

    No, our fee takes care of structural engineer drawings and calculations.

  • Do I need an architect for a loft conversion?

    Why use an expensive architect when an architectural technician can take care of your loft conversion drawings and planning permission?

  • Do I need planning permission for a loft conversion?

    Most loft conversions fall within permitted development rights, meaning that planning permission will not be required.
