Architectural design and planning support for homeowners, property developers and businesses in Colchester.

We work with briefs across Colchester, Tiptree and West Mersea. Horizon Architecture provides design, planning drawings and technical coordination for residential and commercial projects. We serve the area by arrangement; this page does not describe a separate local office.

Planning authority: Colchester City Council

Check the exact property address and planning authority before preparing your submission. Postcodes and postal town names do not always identify the local planning boundary.

Read the conditions as carefully as the approved drawings

Colchester’s guidance explains that planning conditions can apply before work, during construction or before occupation. Once a permission is issued, the design team should review the decision notice and identify what further information must be agreed, alongside the approved drawing references.

Preparing a useful first brief

For a Colchester refurbishment or new home, send the full decision notice if permission already exists. We can prepare a condition tracker and identify drawings or specialist information still needed before the next project stage.

From your brief to a coordinated drawing package

  1. Review the property: confirm the site address, planning history, available survey and intended use.
  2. Explore the design: compare practical layout options, access, daylight and the relationship with neighbouring properties.
  3. Prepare the submission: agree the consent route and coordinate relevant drawings and specialist reports.
  4. Develop the technical design: prepare the agreed Building Regulations and construction information, coordinated with the structural engineer and other consultants.

Your appointment defines the services included. Statutory application charges, surveys and specialist consultant fees are identified separately. Council approval is an independent decision and cannot be guaranteed.

Questions about a project in Colchester

Can you prepare an extension or loft conversion proposal?

Yes. We start with the available plans, your brief and the site constraints, then agree whether a measured survey, planning submission and technical package are required.

Are planning drawings enough for construction?

The planning and technical stages serve different purposes. Your quotation should identify the construction details, engineering and other consultant inputs needed for the intended work.
