Plans & Elevations

We can bring your design ideas to life using our CAD package, drawing existing and proposed elevations and plans.


Permitted Development

Sometimes you can build without planning permission. We can help you with all aspects of permitted development allowance and gain approval by applying for a lawful development cetificate.



These are specialist glazed extensions which will require additional structural calculations and heat loss advise – we specialise in these designs.
