The full drawing set for a Portsea application — location and block plans, existing and proposed floor plans, elevations and sections, drawn to Portsmouth City Council's validation checklist so the pack is accepted first time, delivered in days and revised free until your decision, with a free approval-odds check first.
Portsmouth City Council granted 88% of the householder planning decisions it made in its latest published year — 1 point above the 87% England-wide householder average. Portsea's Georgian dockyard terraces are among the city's oldest domestic buildings and are protected accordingly, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837), Victorian (1837–1901) 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 Portsmouth City Council needs a full application. Portsea carries at least one Article 4 direction, and conservation areas including Portsea and HM Naval Base and St George's Square remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Portsea is determined against an 8-week statutory target.
St George's Square (surviving Georgian square of dockyard officers' houses), Queen Street (the historic commercial spine serving the naval base), The Hard (waterfront gateway to the dockyard and harbour station), White Hart Row (restored early terraces close to the yard walls), HM Naval Base (the historic dockyard and its listed storehouses) and Portsea Green (postwar estate blocks amid the older grain) — these are the Portsea pockets our drawings cover most. Heritage designations here include Portsea and HM Naval Base and St George's Square. Portsmouth City Council weighs each proposal against the Portsmouth Local Plan and the council's Houses in Multiple Occupation SPD, where the naval and maritime heritage of the base and its square sets a strict backdrop for any nearby alteration. Pockets of Portsea are converted flats and shared houses that sit outside householder permitted-development rights.. On roofs the borough is pitched slate roofs on the terraces and parapet roofs on the Georgian dockyard frontages, over dense Georgian and Victorian dockyard workers' terraces, naval and dockyard heritage buildings and postwar and modern infill housing.
Whatever you are building, Portsmouth City Council decides it from the same core set. A location plan at 1:1250 fixes the site on the map with the red-line boundary; a block plan at 1:500 shows the property in its plot; then existing and proposed floor plans and elevations at 1:100 or 1:50 show the house as it is and as it will be. Larger schemes add a section and, where policy requires, a design and access statement. Miss one and the application is returned invalid before an officer has looked at it.
The drawings are also the argument. Portsmouth City Council assesses each proposal against the Portsmouth Local Plan and the council's Houses in Multiple Occupation SPD, and the elevations are where the case is won or lost — ridge and eaves heights, window positions, materials and how the change reads from the street. On Portsea's stock, which runs to dense Georgian and Victorian dockyard workers' terraces, naval and dockyard heritage buildings and postwar and modern infill housing, the same scheme is drawn differently to answer the concerns officers raise here. Portsea's Georgian dockyard terraces are among the city's oldest domestic buildings and are protected accordingly, so the pack is built to pre-empt exactly that.
Where the property sits in a conservation area — Portsea and HM Naval Base and St George's Square among Portsea's — validation is stricter still, often demanding heritage detail and sometimes additional plans. The city-wide Article 4 direction removes permitted-development rights for small HMO conversions in Portsea, where dense workers' terraces beside the dockyard are exactly the stock the direction was written to protect. We confirm the designation before drawing so the pack meets the higher bar first time.
Portsmouth City Council validates against a published checklist before it assesses anything. A typical householder application needs each of these, correctly scaled and labelled:
We draw the complete set — location and block plans, existing and proposed plans, elevations and any section — to Portsmouth City Council's checklist, then lodge it on the Planning Portal, manage validation and answer case-officer queries so the application is decided on its merits, not bounced on a technicality.
Below is Portsmouth City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Portsmouth consents most householder schemes in Portsea, though the dockyard's Georgian heritage and the tight terraced grain drive the refusals. A complete, correctly scaled pack that answers those concerns on the elevations is validated faster and refused less often than one that leaves them for the officer to raise.

Two different things sink an application, and they happen at two different stages. First is validation: a missing block plan, an unscaled elevation, no red line, no north point — Portsmouth City Council returns the whole submission and the clock never starts. Getting the pack right at this stage is purely mechanical, and it is where a lot of self-submitted Portsea applications lose weeks. We draw to the checklist so this never happens.
Second is the planning judgement itself, once the pack is valid. The naval and maritime heritage of the base and its square sets a strict backdrop for any nearby alteration. Across St George's Square, Queen Street and The Hard the recurring refusals are about scale, overlooking and how the proposal sits against its neighbours — all of which are settled on the drawings. We draw the scheme to answer them before submission rather than after a refusal.
The application pack is the same discipline whatever the project. A few of the Portsea neighbourhoods and property types we prepare drawings for most often:
Planning drawings for St George's Square's surviving Georgian square of dockyard officers' houses — scaled, validation-ready and drawn to Portsmouth City Council's guidance.
Planning drawings for Queen Street's the historic commercial spine serving the naval base — scaled, validation-ready and drawn to Portsmouth City Council's guidance.
Planning drawings for The Hard's waterfront gateway to the dockyard and harbour station — scaled, validation-ready and drawn to Portsmouth City Council's guidance.
Planning drawings for White Hart Row's restored early terraces close to the yard walls — scaled, validation-ready and drawn to Portsmouth City Council's guidance.
Planning drawings for HM Naval Base's the historic dockyard and its listed storehouses — scaled, validation-ready and drawn to Portsmouth City Council's guidance.
Planning drawings for Portsea Green's postwar estate blocks amid the older grain — scaled, validation-ready and drawn to Portsmouth City Council's guidance.
The route decides what Portsmouth City Council needs and how long it takes. This is how the common Portsea routes compare.
| Route | When it applies | Core drawings | Typical decision |
|---|---|---|---|
| Householder application | Extensions and alterations to a single house | Location, block, existing & proposed plans and elevations | About 8 weeks |
| Full application | Flats, new units, changes of use | As householder plus site plan and often a section | 8–13 weeks |
| Lawful development certificate | Confirming a scheme is permitted development | Existing & proposed plans and elevations to prove PD limits | About 8 weeks |
| Prior approval | Larger single-storey rear extensions | Plans and elevations plus neighbour notification | About 6 weeks |
In a conservation area such as Portsea and HM Naval Base and St George's Square, householder permitted-development rights are often restricted, so a full application and heritage detail may be required.
A fixed process built around how Portsmouth City Council validates and decides — most drawing sets are submission-ready within seven days of survey.
Send us your Portsea postcode and what you want to build. We confirm your conservation and Article 4 status, tell you which application route applies, and score your odds against live Portsmouth City Council decisions.
We measure the property and plot so the existing plans and elevations are accurate to the millimetre — the base every proposed drawing and every officer judgement is built on.
Chartered designers produce the full validation pack — location and block plans, existing and proposed plans, elevations, any section and a design and access statement — drawn to Portsmouth City Council's checklist.
We lodge the application on the Planning Portal, manage validation and case-officer queries, and revise the drawings free until Portsmouth City Council issues its decision.
Portsmouth City Council validates a householder application against a set list: a location plan at 1:1250 with a red-line boundary, a block plan at 1:500, and existing and proposed floor plans and elevations at 1:100 or 1:50, each with a scale bar and north point. Larger schemes and most conservation-area work also need a design and access statement. If any of these is missing or unscaled the application is returned invalid before it is assessed. This applies to your Portsea address specifically.
Almost always because the drawing pack is incomplete or wrongly scaled — a missing block plan, an elevation with no scale, no red line on the location plan, no north point. Portsmouth City Council checks the pack against its validation list before an officer ever assesses the scheme, so these purely technical gaps cost weeks. Drawing to the checklist from the outset is the simplest way to avoid a return. This applies to your Portsea address specifically.
Yes. We prepare the full drawing set, lodge it on the Planning Portal on your behalf, pay the Portsmouth City Council fee where you prefer us to, and then manage validation and case-officer questions through to the decision. You get the reference number and updates without dealing with the portal or the council yourself. This applies to your Portsea address specifically.
A householder application is a statutory eight weeks from validation, and a full application eight to thirteen weeks depending on scale. The date that matters is validation, not submission — an invalid pack never starts the clock. Because we draw to Portsmouth City Council's checklist the application validates quickly, so the statutory period begins without the delay a returned pack causes. This applies to your Portsea address specifically.
You do not strictly need a planning application, but scaled existing and proposed drawings are still worth having: a lawful development certificate from Portsmouth City Council proves the scheme is permitted development, which lenders and buyers increasingly ask for, and your builder needs the drawings to price and build. In a conservation area such as Portsea and HM Naval Base and St George's Square, permitted-development rights are often removed, so a full application may be needed after all — we confirm which before you commit.
We price each Portsea job individually — the scope of the survey and the size of the drawing set vary from a simple rear extension to a whole-house scheme — and send a fixed, no-obligation quote within one working day. It covers the full validation pack with free revisions until Portsmouth City Council decides. The Portsmouth City Council application fee is separate and paid to the council.
