Professional support when planning matters become complicated.

Unauthorised building works can lead to uncertainty, delays and correspondence from a local planning authority. Whether the issue concerns replacement windows, external alterations, an extension or changes to a property in a conservation area, timely architectural advice can make a difference.

Consultant Line Architects Ltd provides measured surveys, architectural drawings, planning assessments and retrospective application services, alongside professional liaison with relevant planning officers and, where appropriate, managing agents or freeholders.

How We Can Help

Retrospective planning and enforcement services

Retrospective Planning Applications

Preparation of drawings, supporting planning information and submission of applications for works already undertaken.

Planning Enforcement Support

Review of council correspondence, assessment of planning concerns and professional liaison with enforcement officers.

Conservation Area Considerations

Assessment of alterations against the building's character, heritage context and applicable planning requirements.

Replacement Windows & Doors

Architectural assessment of installed windows and doors, including appearance, materials and potential planning constraints.

Managing Agent & Freeholder Liaison

Professional communication on architectural and planning issues, including review of available specifications and concerns.

Building Regulations Initial Review

Initial review of available compliance information and guidance on whether separate Building Control involvement may be needed.

Our Process

A clear route from assessment to submission

01 / Review

Understand the issue

Review council letters, planning history, existing approvals and the work already carried out.

02 / Survey

Inspect the property

Where required, carry out a site visit, measured survey and photographic record.

03 / Strategy

Assess your options

Identify relevant planning and conservation considerations and discuss potential solutions.

04 / Application

Prepare and coordinate

Prepare the agreed planning submission and act as planning agent during determination.

Important Information

Received a planning enforcement letter?

Do not assume that submitting a retrospective application automatically stops enforcement action or extends any deadline. Early assessment helps clarify the nature of the concern and the available planning options.

Our architectural services do not include legal representation, enforcement appeals or guaranteed planning approval. Separate specialist or legal advice may be required depending on the circumstances.

What to send us

For an initial discussion, it helps to provide the property address, photographs of the completed works, any council correspondence, relevant planning decisions and any managing agent or freeholder correspondence.

We will review the information available and discuss an appropriate scope of architectural services.
