We can get you planning permission for your extension!

Croydon Planning Permission & Architectural Services

Our Croydon Planning Consultants & Architectural Consultants at 4D Planning are here to help you obtain planning permission as quickly as possible for a fraction of the price of a typical architect. Anyone can produce drawings, but the skill is knowing how to obtain planning permission!

We make the entire planning and building control process easy and simple. We offer a FREE initial consultation and assist with managing the entire planning application submission process to Croydon Planning Department in the council. We then ensure that the development complies fully with the building regulations and is signed off by Building Control. We can also recommend local builders in Croydon who have worked on our other successful projects.

Planning Advice

We undertake a full property site assessment by looking into the history and context of the site and its surroundings.

Planning Applications

Following the initial site appraisal, a site visit/survey is carried out to gather all the dimensions and required information of the existing site. We then produce all the drawings and planning documents for the application.

Architectural Drawings

4D Planning can produce building regulations for Building Control and construction drawings for tender. We can also provide lease plans and other types of drawings.

Building Regulations

Building Regulations promote high standards for construction and energy efficiency of buildings.

Transport Planning

Our services include: Transport Assessments, Travel Plans / Sustainable Travel Statements, Parking Surveys, Traffic Surveys and Delivery and Servicing Management Plans.

3D Visuals

One of our specialities is to provide our clients with 3 dimensional realistic renders (CGI’s) of proposed and existing schemes. These visuals can be used for planning or marketing purposes and add a lot of value to any project.

Planning Application. December 2019.
“Elie provided us with such a great support during the very difficult and emotional time for us as the planning application took 5 months to approve but he was always there to support and help us when we needed it the most. I would recommend Elie to anyone as he will always do his best! Service with integrity and a very personal approach !”


Loft Conversion. August 2019.
“I used 4D Planning for a planning application of an existing loft conversion. Working with 4D planning was simple and effective. I received clear guidance and Elie (4D Planning) was always available for clarification when I had to decide a course of action.
4D Planning did everything, drawings and paperwork, and made a successful application on my behalf for a Lawful Development Certificate. So I definitely recommend them.”
