Planning Applications for Homeowners - RIBA Chartered Practice

We help homeowners understand and unlock their properties potential to then prepare and submit all information required to the Local Authority using either a Householder Application or via Permitted Development.

Atelierdb can help Clients understand potential project Build costs, but initially there has to be design discussions to understand the client brief and thereafter what each unique property could achieve in terms of layout and design. Having an Architect prepare and submit a comprehensive set of drawings and reports to a Local Authority demonstrates to the Planners that the applicant has brought an experience Consultant on board to produce designs of high quality – which is a key requirement of most Planning Policies.

We have excellent 5 star reviews and provide a detailed and inclusive service to clients to make sure that critical design decisions are made early doors with all the facts to hand prior to submitting an Application. Careful consideration of structure, materials, party walls, heights, overlooking and enclosure must be undertaken when developing designs for any house extension to ensure that the local Planning Policy is not compromised which could warrant a refusal.

Get in touch

Simply send us the following information to allow us to provide an indicative lump sum prices for RIBA stages 0-3, from Concept to Submitting an Application:

  • Property address: this will allow us to review the local context and house type
  • Which elements are you wanting to extend
  • Any historic property sales plans or photographs to allow us to see the present accommodation offer
  • An outline brief of your aspirations and key needs for the house extension
  • Any critical dates to start or complete
  • Do you need services just to planning application or full services up to handover of completed project
  • Indication of complete budget including VAT. This would include for Consultants, Kitchen, Bathroom goods, Floor and Wall finishes

Planning Application Timescales

Once submitted a Householder Planning Application should take no more than 8 weeks. Similarly an application for a Certificate of Lawfulness (Permitted Development route) will take up to 8 weeks.

For simple extensions 8 weeks should be sufficient to allow the Case Officer/Planning Team to determine the application. We are however experiencing significant delays from some Planning Departments due to internal resourcing issues and some applications can take up to 12 weeks. There is no hard or fast rule, with Planning Departments working to their own timescales which can be very frustrating. At Atelierdb we continually and politely press for responses from Planning Departments – diplomacy is the only option in this situation. The ability of Planning Departments to comply with the 8 weeks determination period can differ by Case Officer, with some longer time-served Officers able to determine applications under Delegated Powers whereas new Officers take more time and consultation with team leaders and Principal Planners within their department.

We are here to help

    We used Atelierdb to design and project manage our kitchen extension. We found David extremely professional and with great attention to detail. The design process was tailored and iterative to ensure we met our objectives wherever possible, and the project management service was invaluable to keep us on track (and sane!) during the building works. We are now delighted with the new living space that it has achieved for us.

    It has been an absolute pleasure working with Atelierdb from the initial planning and design of the project right through to completion. Not only did they deliver on the brief, they managed to exceed our expectations on what could be done to the space (whilst staying within budget!). The entire process remained stress-free thanks to the ongoing communication between Atelierdb and the building contractor, allowing the project to be completed on time and to a very high standard. Highly recommended.

    We appointed Atelierdb to re-design our house prior to a full renovation. We were extremely pleased with the service, David and his team provided many layout possibilities, they were flexible and professional throughout and always had solutions. I would highly recommend them.

    We're very happy with the basement living space which was created as part of a larger renovation of the property. atelierdb helped us focus on the relevant issues at the relevant time and were particularly diligent in administering the building contract.

    We have recently completed our kitchen extension project and I can only recommend David and his team. The support and patience during the design phase was great and the project management and support during the construction has been really helpful. They turned an idea into an amazing living space.

    We have since moved into a larger property and project and we are now working with atelierdb for the second time.
