Architectural Service in Merton – Process

Any work under Merton Council, we would undertake a property site assessment by looking into its history and context of the site with its surroundings. In the process of design we aim to be up to date with all the regulations, taking into consideration the conservation and heritage sites and we approach it with a sympathetic proposal to consider the characteristic surroundings. The rules and regulations for planning applications and building regulation vary from council to council and as stated above we always keep ourselves aware of the changes in the Merton borough. Additionally, we would take time to study the reasons as to why the other properties get approved and refused within the area helping us to better our understanding and maintain a good success rate. Therefore in Merton architects in our practice are one of the most reliable to work with. Our in house experienced team are always there to help you. Call us to find out more on 0203 409 4215. We provide a full range of services with regards to all manner of planning permission and drawing types in the Merton area.
