Refused by Three Rivers District Council? We read the decision notice, tell you honestly whether to appeal or resubmit, and prepare the drawings and statement that answer each reason for refusal on the Planning Inspectorate's terms.
Three Rivers District Council granted 93% of the householder planning decisions it made in its latest published year — 6 points above the 87% England-wide householder average. Metropolitan Green Belt covers roughly three-quarters of the district, so the plan pushes growth onto brownfield and town-centre sites rather than releasing countryside, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), Edwardian (1901–1910), interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which Three Rivers District Council needs a full application. Three Rivers carries at least one Article 4 direction, and conservation areas including Rickmansworth, Chorleywood Common and Moor Park remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Three Rivers is determined against an 8-week statutory target.
Rickmansworth (the historic market-town core with a Victorian and Edwardian centre and its own conservation area), Chorleywood (a Metro-land commuter village of Arts and Crafts and interwar houses around Chorleywood Common), Moor Park (a private gated estate of large interwar detached houses under an Article 4 direction), Croxley Green (mixed Victorian and interwar suburban housing gathered around the green), Abbots Langley (a village with a historic core and postwar suburban growth) and Sarratt (a rural green-belt village of historic vernacular cottages) — these are the Three Rivers pockets our drawings cover most. Heritage designations here include Rickmansworth, Chorleywood Common, Moor Park, Croxley Green, Sarratt and Abbots Langley. Three Rivers District Council weighs each proposal against the Three Rivers Core Strategy (adopted October 2011) and Development Management Policies LDD, where part of the district around Chorleywood and Rickmansworth falls within the Chilterns National Landscape (AONB), where landscape protection is at its highest. Converted flats are common through Rickmansworth and around the stations, and none of them hold householder permitted-development rights.. On roofs the borough is hipped roofs on the 1930s Metro-land semis and gabled and dual-pitch roofs on the older village cottages, over interwar and Edwardian Metro-land semi-detached and detached houses across Chorleywood, Croxley Green and Moor Park, Victorian and Edwardian terraces around Rickmansworth, postwar estate housing at Abbots Langley and South Oxhey and period vernacular cottages in the green-belt villages of Sarratt and Heronsgate.
Two routes exist and they suit different refusals. A free-go resubmission — a fresh application within twelve months of the refusal, on the same site and in the same description — costs no fee and lets you change the scheme. An appeal keeps the scheme as refused and asks an Inspector to disagree with Three Rivers District Council. Where the refusal reasons are about design detail that can be fixed, resubmission is usually faster; where they are about principle, an appeal is the only route that resolves it.
The decision notice is the brief. Each numbered reason cites policy and states a harm, and the appeal has to meet each one with evidence — sections showing daylight, elevations showing the relationship to neighbours, a site plan proving separation distances. Assertion loses appeals. Three Rivers is largely interwar and Edwardian Metro-land semi-detached and detached houses across Chorleywood, Croxley Green and Moor Park, Victorian and Edwardian terraces around Rickmansworth, postwar estate housing at Abbots Langley and South Oxhey and period vernacular cottages in the green-belt villages of Sarratt and Heronsgate, and hipped roofs on the 1930s Metro-land semis and gabled and dual-pitch roofs on the older village cottages shape what the Inspector will accept as characteristic here.
Metropolitan Green Belt covers roughly three-quarters of the district, so the plan pushes growth onto brownfield and town-centre sites rather than releasing countryside, which frequently appears in refusal reasons and therefore has to be addressed head-on. The Moor Park Article 4 direction covers the private Moor Park estate and conservation area, removing permitted-development rights so external alterations to these large interwar houses need consent, and further conservation areas such as Rickmansworth and Chorleywood Common layer additional controls.
We give an honest read of the decision notice first. An appeal is usually the right route where:
We take each numbered reason for refusal and answer it with a drawing or an evidenced statement — not with a restatement of the original application. That is the difference between an appeal that reads as a complaint and one that reads as a case.
Below is Three Rivers District Council's real decision record, drawn from official planning statistics and refreshed as new data lands. Three Rivers grants a high share of decisions overall, with green-belt containment across most of the district and Chilterns AONB protection the recurring constraints on larger schemes. Knowing what this authority actually refuses, and why, is the starting point for deciding whether to appeal or to redesign.

Across Rickmansworth, Chorleywood and Moor Park, the appeals that succeed are narrow and evidenced. They show the daylight test drawn rather than described, they cite the Inspector's own decisions on comparable sites, and they concede the points that are not worth arguing so the case concentrates on the ones that are. An appeal that disputes every reason equally reads as unfocused and usually fails on the strongest one.
Part of the district around Chorleywood and Rickmansworth falls within the Chilterns National Landscape (AONB), where landscape protection is at its highest. Most householder appeals are decided by written representations, with the Inspector visiting the site unaccompanied. That makes the drawings the primary evidence: what is not on the page is not in front of the Inspector. We prepare the set on that basis, and where the honest answer is that the refusal was sound, we say so and redesign instead.
We prepare appeal drawings and statements across Three Rivers. A few of the areas where refusals come up most often:
Appeal drawings for Rickmansworth — the historic market-town core with a Victorian and Edwardian centre and its own conservation area — answering Three Rivers District Council's reasons for refusal with evidence rather than assertion.
Appeal drawings for Chorleywood — a Metro-land commuter village of Arts and Crafts and interwar houses around Chorleywood Common — answering Three Rivers District Council's reasons for refusal with evidence rather than assertion.
Appeal drawings for Moor Park — a private gated estate of large interwar detached houses under an Article 4 direction — answering Three Rivers District Council's reasons for refusal with evidence rather than assertion.
Appeal drawings for Croxley Green — mixed Victorian and interwar suburban housing gathered around the green — answering Three Rivers District Council's reasons for refusal with evidence rather than assertion.
Appeal drawings for Abbots Langley — a village with a historic core and postwar suburban growth — answering Three Rivers District Council's reasons for refusal with evidence rather than assertion.
Appeal drawings for Sarratt — a rural green-belt village of historic vernacular cottages — answering Three Rivers District Council's reasons for refusal with evidence rather than assertion.
Three responses to a refusal, with different costs, timescales and prospects.
| Route | Deadline | Typical timescale | Best where |
|---|---|---|---|
| Householder appeal | 12 weeks from the decision | About 8–12 weeks | The refusal turns on principle or a disputed harm |
| Section 78 appeal (other) | 6 months from the decision | Several months | Larger schemes, change of use, new dwellings |
| Free-go resubmission | 12 months from the decision | 8 weeks | The reasons are fixable design detail |
| Fresh application, redesigned | No deadline | 8 weeks | The scheme needs a different approach entirely |
Deadlines from the Town and Country Planning Act 1990, section 78, and the Planning Inspectorate's published appeal procedures.
A process built around the decision notice, because that is what the Inspector reads first.
Send us the decision notice and the refused drawings. We tell you honestly whether the reasons are appealable, whether a resubmission is faster, and how Three Rivers District Council has fared on comparable appeals.
We gather the material that answers each reason — daylight geometry, separation distances, decided appeals on similar sites, and the relevant policies read in full rather than in extract.
We prepare the drawings the Inspector needs and a statement of case that takes each numbered reason in turn, conceding what should be conceded and evidencing the rest.
We lodge the appeal inside the deadline, respond to the council's statement, and revise free until the Inspector issues a decision.
Twelve weeks from the date on the decision notice for a householder appeal, and six months for most other section 78 appeals. The deadline is strict and the Planning Inspectorate will not accept a late appeal, so the first thing we do on a Three Rivers refusal is check the date and work backwards from it. Three Rivers District Council is the decision-maker.
It depends what the reasons say. If they identify design detail you are willing to change, a free-go resubmission within twelve months costs no application fee and usually resolves faster. If they refuse the principle — that an extension of this type does not belong here at all — only an appeal settles it, because a resubmission would meet the same objection. This applies to your Three Rivers address specifically. Three Rivers District Council is the decision-maker.
Nationally, a minority of householder appeals succeed, and the ones that do tend to be narrow, evidenced and focused on a single disputed harm. We look at how Three Rivers District Council's refusals have fared at appeal and at comparable decisions nearby before advising, and we will tell you when we think the refusal was sound — an appeal with no prospect costs months.
The scheme itself cannot change on appeal — the Inspector determines the application as refused. What usually needs preparing is evidence: sections showing daylight, elevations showing the relationship to neighbours, and context drawings showing what already exists on the street. Those explain why the refused scheme causes no harm, without altering it. This applies to your Three Rivers address specifically. Three Rivers District Council is the decision-maker.
In most written-representation appeals, yes — usually unaccompanied, viewing the site from public land and neighbouring property where access is arranged. That is why the drawings matter so much: the Inspector sees the site once, briefly, and everything else comes from the paperwork you submitted. This applies to your Three Rivers address specifically. Three Rivers District Council is the decision-maker.
Only where the council has behaved unreasonably — refusing against its own officer's clear recommendation without evidence, or failing to substantiate a reason for refusal. Costs awards are the exception rather than the norm, and they are decided separately from the appeal itself. Where the grounds genuinely exist, we make the application alongside the appeal. This applies to your Three Rivers address specifically. Three Rivers District Council is the decision-maker.
We quote each Three Rivers appeal individually after reading the decision notice, because the work depends entirely on how many reasons are in play and what evidence they demand, and send a fixed, no-obligation quote within one working day.
