Why Choose GPO Designs?

We have submitted hundreds of applications for many different schemes and projects, and have experience working with many different local councils including Chelmsford, Maldon, Basildon, Southend, Braintree, Colchester, Brentwood, Thurrock, Rochford, Castle Point, Tendring, Brent, Bromley, Hackney and Thanet.

GPO Designs has a wealth of knowledge about planning and building control regulations required by these councils, and specialises in producing drawings of a high standard for projects large and small, residential and commercial.  

We can help you realise the potential of your home, create additional space and increase the value of your property.  We pride ourselves on being friendly and straight forward. We provide easy to understand guidance on all aspects of the planning process, and can also offer pre-application advice.  

GPO designs provides fixed price quotes with no hidden extras or spiralling costs.  For those who need their plans to be produced more quickly we do offer a fast track service for an additional fee.

How We Work

Free Telephone Consultation

When you contact us we will offer free telephone advice and guidance prior to any appointment to visit you.  This ensures that you are aware of options available to you (for example, whether your requirements actually need planning permission or drawings) and gives you a greater understanding of what will happen.  If you provide us with the site address we can also look up your details on our maps and be able to provide even more detailed advice, all free of charge.

Site Visit

The next step would then be a site meeting, when you make an appointment for us to visit you at your property to provide a consultation.  This will be at a time to suit you - daytime, evening and weekend appointments are always available.  At this point we will discuss your requirements further, offer alternative ideas, and provide any guidance or advice that you may need.

Measurements and Drawings

Once we have discussed your requirements and you are happy to proceed we will take measurements of your property in order to produce detailed plans and drawings. This can be completed at the same time as your site visit or if you prefer you can book a second appointment and we will return to complete this. Our drawings include 3D visuals of your existing property and the proposed changes, elevation plans, floor plans and site & block plans. We can provide these drawings via email and by post.

Unlimited Revisions

We offer unlimited revisions of your plans until the application is submitted. We want you to be entirely happy with the plans and fully understand that you may wish to make some alterations, especially as our 3D drawings really help you see clearly how the changes will make your property look and how everything fits in.

Plans Submitted

Once the plans are submitted to the council we will keep you updated with progress and we will make further changes that may be necessary to address any concerns the council raise during the course of the application.

Support to Construction

We can provide assistance in helping you select local building contractors. We can also help review a builder that you have selected. Once construction begins we can provide onsite support to your contractors or review your contractors work on your behalf.  Some of our clients have found this particularly useful as they are able to discuss the work and ask for advice. On site support is subject to a separate quotation and would be tailored to meet your requirements.

Fixed Prices

We provide fixed prices on our services and pride ourselves in not having any hidden extra costs.  We provide a written quote which will also outline payment milestones, so that you are only paying for work that we have already undertaken.
