Horizon Architecture · London and Essex
Architectural design and planning support for homeowners, property developers and businesses in Tendring.
We work with briefs across Clacton-on-Sea, Frinton-on-Sea, Walton-on-the-Naze and Harwich. 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.
OFFICIAL PLANNING DATA / APRIL 2025–MARCH 2026
From 1 April 2025 to 31 March 2026, the authority received 889 applications and issued 837 decisions. Of those decisions, 710 were granted and 127 refused: a refusal rate of 15.2%.
Received applications and decisions are separate flows: a decision during the year may concern an application received earlier. The refusal rate is refusals divided by decisions, not by applications received. These council-wide figures do not predict the outcome of an individual proposal.
Householder developments accounted for 418 decisions, with 46 refusals (11.0%). This category includes qualifying extensions and alterations within a house’s curtilage; flats and the creation of additional homes fall outside it.
On a small screen, scroll the table sideways to see all figures.
| Development category | Decided | Granted | Refused | Refusal rate |
|---|---|---|---|---|
| Major developments | 34 | 31 | 3 | 8.8% |
| Minor developments | 255 | 199 | 56 | 22.0% |
| Householder developments | 418 | 372 | 46 | 11.0% |
| Change of use | 49 | 39 | 10 | 20.4% |
| Advertisements | 31 | 28 | 3 | 9.7% |
| Listed building consent: alter or extend | 48 | 39 | 9 | 18.8% |
| Listed building consent: demolish | 1 | 1 | 0 | 0.0% |
| Relevant demolition in a conservation area | 1 | 1 | 0 | 0.0% |
| All categories | 837 | 710 | 127 | 15.2% |
The eight categories are separate and add up to the authority total. “—” means no decisions in that category, so no refusal percentage can be calculated.
No. The official return combines full, outline and reserved-matters applications, section 73 variations or removal of conditions, and related consents such as listed-building and advertisement consent. Major and minor describe development categories, not the permission route. These tables do not supply a reliable full-applications-only total or received applications by category.
Prior approvals and lawful development certificates are reported separately. Discharge of conditions, non-material amendments and county matters are outside these totals.
The table shows refusals by development category. Minor developments had the largest number of refusals in this authority: 56. That is a count, not a measure of how difficult an individual proposal will be.
The aggregate return does not record reasons for refusal. For a particular property, review the council’s decision notice, officer report and relevant policies. Read our planning refusal review guide for the next steps.

LOCAL PLANNING / Tendring
Tendring has been updating its conservation appraisals, with adopted documents for places including Clacton Seafront, Harwich, Frinton and Walton, and several villages. The council's conservation directory lists adopted appraisals and boundaries separately from consultation material. Check which version applies to the property before designing an extension or changing an exterior. A proposal shown in a consultation document should not automatically be treated as an adopted boundary or rule.
Article 4 controls are another separate check. Tendring's direction register includes Jaywick and particular sites around the district, alongside information about HMO changes of use. It expressly warns that other directions also exist. Identify the precise parcel of land and the work covered by the relevant order; absence from a short list is insufficient evidence of unrestricted permitted development. This check is useful for boundary works and land uses as well as extensions.
For an early design review, we recommend bringing the adopted appraisal, photographs of the street and a plan showing existing trees and boundaries. Tendring's tree guidance explains the separate notice requirements for qualifying trees in conservation areas. A design that retains a tree still needs to consider the practical relationship between its position and the proposed building work. Record intended pruning, removal or access changes explicitly rather than leaving them outside the project brief.
The national householder target is eight weeks from a valid application, subject to agreed extensions of time. It is a decision target, not guaranteed approval. Allow time beforehand to resolve the correct appraisal, any direction and the supporting information for the application.
Our Essex two-unit residential design and construction drawings show the relationship between architectural layout, interiors and technical information. The published project identifies Essex rather than a specific council area, so it is presented as a wider-county example.

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.
Tendring provides a public service for viewing planning applications and commenting on proposals. Use the records to locate relevant plans and decisions, then assess the proposal against the applicable development plan and the actual site conditions. Application records can inform a design review but are not a substitute for a measured survey.

For a coastal home or commercial premises in Tendring, send the exact address, existing plans and the intended use of each space. We can identify the questions to resolve about the site, access, layout and any specialist assessments before preparing the submission.
Explore our house extension design, loft conversions, new build architecture, interior design and Building Regulations drawing packages. For an existing refusal, see our planning refusal review service.
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.
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.
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.
