Garden Room Drawings in West Kensington W14
Fixed-fee, MCIAT-chartered garden room drawings for West Kensington (W14) homeowners — London Borough of Hammersmith & Fulham validation and local constraints handled from the start.
West Kensington (W14) is defined by its red-brick Victorian mansion flats — the Gunter family developed much of the district as planned mansion-block and terrace streets, and a large share of the housing is now flats rather than whole houses. That tenure shapes every project: rear, roof and party-wall work here typically touches more than one household.
The Gunter Estate, Barons Court and Sinclair Road conservation areas cover much of the district and protect that planned red-brick character. We establish the conservation boundary, the tenure and the block's shared elements before recommending a route, and draw to the borough's guidance.


Planning in West Kensington (W14): what to know before you apply
W14 sits across the Gunter Estate, Barons Court and Sinclair Road conservation areas, which protect the planned red-brick mansion-flat streets and remove permitted development rights on many of them — and because so much of the stock is flatted, extensions and loft work are assessed against shared roofs, rear elevations and party walls as well as conservation character. London Borough of Hammersmith and Fulham does not publish an Article 4 schedule to the national open-data register, so an empty entry there is not evidence of absence — we confirm the current directions with the council before advising.
Typical West Kensington housing stock

Garden Room Drawings for West Kensington (W14) homes: the package and the process
Every garden room drawings we prepare for an West Kensington property is drawn to London Borough of Hammersmith & Fulham’s validation standards and tuned to the W14 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
A garden room, garden office or outbuilding is one of the simplest ways to add usable space in London without extending the main house — a home office at the end of the garden, a gym, a studio, or additional storage. Most of these structures fall within permitted development rights, meaning they can be built without a full planning application, but the rules that govern what qualifies are specific: single-storey construction, height limits that tighten close to a boundary, incidental rather than independent use, and a limit on how much of the garden can be covered by outbuildings in total. DrawingsDirect checks your garden room against these rules before drawing anything, and produces the drawings needed either for a Lawful Development Certificate or, where the project falls outside permitted development, for a full planning application.
Garden rooms are also one of the areas most commonly built incorrectly, because homeowners assume a small structure is automatically exempt from any process. In reality, a garden room used as extra sleeping accommodation, positioned in a front garden, exceeding the eaves height allowed near a boundary, or built on a property that sits in a conservation area or under an Article 4 direction can all fall outside permitted development and need planning permission. Establishing which category your project falls into at the outset avoids building something that later has to be altered or removed.
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.
