About GPO Designs 


GPO Designs provides Architectural Services and specialises in the preparation of Planning Permission Applications, Building Control Applications and Planning Appeals for new build houses, residential extensions, loft conversions, garage conversions and conservatories. If you are not sure what is possible or what an extension or conversion would look like we can help by producing a realistic artists impression which shows your property or site with and without the changes.


GPO Designs was established in 2010 by Mike and Georgina Otter. The business was started in response to a gap in the market for high quality, low cost Planning Application and Building Control Application services.


Our aim is to offer a high quality service for the best possible price. GPO Designs initially offered services only within Essex but this has now been extended across the UK with our self survey planning and building control planning services


We advertise our architectural and building drawing services in a range of local publications including locally within South Woodham Ferrers and the wider area including Chelmsford, Danbury, Ingatestone, Burnham-on-Crouch and Southminster. We have also recently advertised in "Your Village Voice" covering Hatfield Peveral, Boreham, Little Waltham and surrounding villages.  


During 2013 we extended our operating area for our Premium Planning Services to include the entire South East of England (including Hertfordshire, Kent, Essex, Surrey, Bedfordshire, Buckinghamshire, West Sussex, Berkshire, and Cambridgeshire) . More locally we are are also targeting our Premium Planning Application and Building Plans services to Southend, Colchester, Hornchurch, Brentwood and surrounding areas. Please see our list of recent adverts for more details.  


Our contact details can be found on our Contact and Enquiry page.
