House Extension Drawings in Haringey
Fixed-fee, MCIAT-chartered house extension drawings for Haringey homeowners — London Borough of Haringey validation and local constraints handled from the start.
Haringey pairs some of North London's most sought-after Edwardian housing with tightly controlled hilltop conservation. The famous Harringay 'Ladder' streets, the Edwardian mansion blocks and villas of Crouch End and Muswell Hill, and the streets of Hornsey, Stroud Green and Wood Green make hip-to-gable loft conversions and rear extensions the borough's signature projects, while the Georgian and Victorian houses of Highgate carry stronger design control and Tottenham adds its own terraced and villa character. Sloping sites around Highgate and Muswell Hill also shape how extensions and any below-ground work are designed.
Constraints here are specific to your address. Conservation areas at Highgate, Crouch End, Muswell Hill, the Harringay Ladder Gardens, Tottenham Green and Bruce Castle control frontage and roof alterations and can remove permitted development, and Haringey applies Article 4 directions removing permitted development for HMO conversions in designated wards. Protected views toward Alexandra Palace and across the borough's hills influence roof-level proposals on prominent sites, so a dormer or roof extension may be assessed against that setting. We flag which of these bite for your street before drawing.
We prepare Haringey planning drawings that respect the established Edwardian building line and roofline the council expects, which is what carries applications to consent on the Ladder rather than a standard template. We check permitted development eligibility and any conservation-area or protected-view constraint first, confirming permitted development with a Lawful Development Certificate where a loft or extension qualifies. The fee is agreed up front as a fixed figure, usually around 30% below an architect's charge for the same council-accepted drawings, with free redraws until Haringey approves. The council decides most householder applications within the statutory eight-week period once validated, so we submit validation-first to avoid the drawing queries that cause most delay.

House Extension Drawings for Haringey homes: the package and the process
Every house extension drawings we prepare for a Haringey property is drawn to London Borough of Haringey’s validation standards and tuned to the local constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
A well-drawn extension adds space and value while sailing through the council; a poorly-drawn one triggers objections and refusals. DrawingsDirect draws rear, side-return, wraparound, double-storey and basement extensions for London homes — sized to your borough's tolerances, with daylight and neighbour impact considered before the planners raise them.
Which extension types do you draw?
Every London extension is shaped by the plot, the neighbours and the borough's design guidance. We draw them all.
Rear extension
A single-storey rear extension is often permitted development within depth limits — ideal for an open-plan kitchen-diner.
Side-return
Fills the alley beside a Victorian terrace, widening the ground floor without losing garden.
Wraparound
Combines a rear and side-return extension for a transformative ground floor, usually needing planning permission.
Double-storey
Adds space above and below, subject to tighter scale and neighbour-impact scrutiny.
Basement
Creates space downward where footprint is limited, with structural and party-wall care.
Do I need planning permission for a house extension in London?
Single-storey rear extensions within permitted development limits (up to 6m for terraced/semi-detached homes under the larger-home scheme, subject to neighbour consultation) may not need a full application. Wraparounds, double-storeys and anything in a conservation area usually do. We assess your plot and recommend the right route before drawing.
| Extension | Typical route | Package | Fee from |
|---|---|---|---|
| Single-storey rear | Permitted development / householder | Planning + building regs | £1,100 |
| Side-return | Householder planning | Planning + building regs + structural | £1,600 |
| Wraparound | Householder planning | Full package + structural | £2,200 |
| Double-storey | Householder planning | Full package + structural | £2,400 |
