Horizon Architecture · London and Essex
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.
OFFICIAL PLANNING DATA / APRIL 2025–MARCH 2026
From 1 April 2025 to 31 March 2026, the authority received 1,137 applications and issued 1,074 decisions. Of those decisions, 886 were granted and 188 refused: a refusal rate of 17.5%.
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 579 decisions, with 94 refusals (16.2%). 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 | 27 | 22 | 5 | 18.5% |
| Minor developments | 225 | 178 | 47 | 20.9% |
| Householder developments | 579 | 485 | 94 | 16.2% |
| Change of use | 89 | 67 | 22 | 24.7% |
| Advertisements | 73 | 64 | 9 | 12.3% |
| Listed building consent: alter or extend | 80 | 70 | 10 | 12.5% |
| Listed building consent: demolish | 1 | 0 | 1 | 100.0% |
| Relevant demolition in a conservation area | 0 | 0 | 0 | — |
| All categories | 1,074 | 886 | 188 | 17.5% |
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. Householder developments had the largest number of refusals in this authority: 94. 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 / Colchester
Colchester's heritage guidance brings together listed buildings, conservation areas and archaeology. For an extension involving new foundations, establish early whether archaeological advice or investigation is relevant to the address. The council supplies investigation briefs but does not undertake the archaeological work itself. We recommend identifying any specialist input while comparing layout options, so that the scope, cost and sequencing can be considered alongside the architectural design.
North Station Road and Environs illustrates why a local check matters. The council records Article 4 directions effective from April 2024, with separate controls for dwellinghouses and commercial premises. The residential direction covers specified alterations including windows, doors, roofs, porches, boundaries and external painting. The commercial direction withdraws the specified Class MA route from commercial use to housing along North Station Road. A house extension and a conversion of business premises therefore need different consent assessments.
Read the sealed direction and adopted boundary rather than relying on the street name alone. The revised conservation boundary includes particular properties on Causton Road, and the appraisal explains the area's significance. As a practical preparation step, mark the proposed work on photographs and identify exactly which surfaces, openings or boundaries would change. That makes it easier to assess the direction's relevance and explain the design response without assuming every alteration is either prohibited or automatically permitted.
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. Include time to commission any necessary heritage or archaeological material before submission.
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.
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.

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.

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.
