Garden Room Drawings in Shepherds Bush W12
Fixed-fee, MCIAT-chartered garden room drawings for Shepherds Bush (W12) homeowners — London Borough of Hammersmith & Fulham validation and local constraints handled from the start.
Shepherds Bush (W12) splits into two very different planning contexts. Around Askew Road and the Uxbridge Road the housing is standard Victorian and Edwardian terrace, where rear and loft projects follow the familiar pattern. North and west, though, the Old Oak and Wormholt estates are a garden-suburb cottage estate the London County Council built between 1912 and 1928 — and a conservation area of real character.
That means an extension on Bryony Road or Wormholt Road is a materially different application from one on an ordinary terrace nearby, with tighter control over roof form, materials, hedges and verges that define the estate. We establish which context a Shepherds Bush property sits in before drawing to the borough's guidance.


Planning in Shepherds Bush (W12): what to know before you apply
W12 carries the Old Oak & Wormholt conservation area over its LCC cottage estate, where permitted development rights are curtailed and the Arts-and-Crafts character, privet hedges and grass verges are actively protected — so extensions there are a different proposition from the ordinary terraces around Askew Road. London Borough of Hammersmith and Fulham does not publish an Article 4 schedule to the national open-data register, so we confirm the current directions and conservation boundary with the council before advising.
Typical Shepherds Bush housing stock
Victorian and Edwardian terraces around Askew Road and the Uxbridge Road, and the low-density Arts-and-Crafts-influenced cottage housing of the Old Oak and Wormholt estates built by the London County Council between 1912 and 1928.

Garden Room Drawings for Shepherds Bush (W12) homes: the package and the process
An outbuilding is assessed on its use as much as its size. It has to be incidental to the enjoyment of the house, and the drawings show that: the internal layout, the total footprint against the garden area, and the height set out — with the eaves line drawn explicitly where the building sits close to a boundary.
If the room will be used year-round, the technical drawings matter more than the planning ones. Insulation, damp-proofing, ventilation and the electrical supply route are drawn so the building performs as a room rather than as a shed, and so any later question about its status has a documented answer.
Garden size is the practical constraint. The building has to sit within the rules on footprint and height without taking the garden it is meant to enjoy, and a position within two metres of a boundary caps the overall height — which decides the roof form before anything else does.
Is a garden room permitted development in London?
A garden room is generally permitted development if it is single storey, has a maximum eaves height of 2.5 metres where it sits within 2 metres of a boundary, does not exceed the wider height limits that apply further from the boundary, is used for a purpose incidental to the enjoyment of the main house — such as a home office, gym, studio or storage — rather than as independent living accommodation, and, combined with any other outbuildings, extensions and existing additions, does not cover more than 50% of the garden. Meeting all of these conditions at once is what qualifies a garden room as permitted development rather than requiring a planning application.
Do I need planning permission for a garden room?
Planning permission is needed instead of relying on permitted development where the garden room includes sleeping accommodation or is intended as a separate annexe for independent living, where it is positioned in a front garden rather than to the rear or side, where its height or position relative to boundaries exceeds the permitted development limits, or where the property sits within a conservation area, is a listed building, or is subject to an Article 4 direction removing some or all permitted development rights for outbuildings.
If any of these apply, we design the garden room and prepare a full planning application drawing set for submission to your borough via the Planning Portal, in the same way as any other planning application.
Is a Lawful Development Certificate worth getting for a garden room?
A Lawful Development Certificate (LDC) is not a legal requirement for a genuinely permitted development garden room, but it is a formal, borough-issued document confirming that the structure was lawful at the time it was built, based on the rules in force then. This is valuable protection: permitted development rules can be interpreted differently by different people, garden coverage calculations involve every existing outbuilding and extension on the plot, and a future buyer's solicitor will often ask for evidence that an outbuilding was lawfully constructed. Without an LDC, resolving a query at sale stage — sometimes years after the garden room was built — can be far more time-consuming than obtaining the certificate up front.
