Hammersmith & Fulham
We design extensions, loft conversions and family-home refurbishments around Parsons Green, preparing the planning and building regulation drawings these terraced-house projects require.

The short answer
For basements, yes: Hammersmith & Fulham has applied a borough-wide Article 4 direction since 26 April 2018, so basement works in Parsons Green need a full planning application rather than permitted development. Above ground it depends on the address — the streets around the Green include a named conservation area, so roof and external changes face closer scrutiny where the designation applies.

Parsons Green is a sought-after family enclave within Fulham, centred on its namesake green and characterised by attractive Victorian and Edwardian terraces. As in the wider Fulham area, the typical project is the family-home transformation: a rear or side-return extension for a larger kitchen-dining space, a loft conversion for an extra bedroom or bathroom, and a refurbishment to bring the whole house up to standard.
These terraced-house projects share recurring considerations: party wall procedures with neighbours, drainage and build-over along the side return, daylight and amenity impacts, and conservation-area scrutiny of roof and external changes where it applies. We design to handle these and prepare the planning and building regulations information needed to obtain approval and build.
Parsons Green proposals are assessed by Hammersmith & Fulham against the borough’s local plan and any relevant conservation-area appraisal, confirmed per address. We design to the local context, coordinate structural and party wall input, and produce a coordinated tender package for pricing and construction.
Local analysis
Parsons Green combines family terraces, larger Peterborough Estate houses, flats over local parades, buildings around the Green and Hurlingham-side homes with a strong open-space and streetscape context.
The first check is the Hammersmith & Fulham designation, including Parsons Green conservation material, nearby Walham Green or Moore Park boundaries and any Article 4 or estate controls.
The audience may include Hammersmith & Fulham planning, conservation officers, freeholders, managing agents, party wall surveyors, structural engineers and contractors used to tight terrace sites.
Peterborough Estate and Parsons Green houses can make facade rhythm, roofscape, front gardens, rear closet wings, party walls, basement risk, drainage and acoustic separation part of the early brief.
A Parsons Green tender pack should explain neighbour protection, access through tight streets, waste storage, scaffold positions, party-wall interfaces and how the works avoid damaging retained period fabric.
Since 26 April 2018, Hammersmith & Fulham's borough-wide Article 4 direction has meant that basement works in Parsons Green need a full planning application. There is no permitted-development route to fall back on, so the planning submission has to carry the whole case: drawings that describe the excavation and its relationship to the terrace, a credible position on drainage, and a design that respects the party walls shared on both sides of a Victorian or Edwardian terrace. Because the application will be judged against the borough's local plan, and against conservation-area material where it applies, external expression matters as much as what happens below ground.
Sequence the work accordingly. Commission a measured survey and gather drainage records before fixing the layout, because the position of the side-passage drain often shapes what can be dug and where. Submit for planning first — householder applications carry a statutory target of around eight weeks once valid — and hold the building regulations package for the next stage, since planning drawings and compliance drawings answer different questions. Party wall procedures under the Party Wall etc. Act then follow with both neighbours before excavation starts, and it is honest to say that this sequence takes months before a contractor arrives.
The recurring constraints on Parsons Green extensions are physical rather than procedural: the drain running along the side passage and the party walls shared with neighbours on both sides. A side-return extension for a kitchen-dining space typically builds over or hard against that drain, so its position, depth and condition should be established early — from records and, where records are thin, from an on-site check — because moving or building over drainage is a design decision, not a construction afterthought. The dual-party-wall condition of a mid-terrace house means an extension can trigger notices to two households under the Party Wall etc. Act, and steel or wall loads bearing on shared structure need coordinated structural input before the drawings are priced.
These constraints reward a particular order of work. Start with the survey and the drainage evidence, then test the side-return width and rear layout against them, then decide the consent route — a planning application where conservation-area or other designations apply at the address, or a lawful development certificate where the works genuinely fall within permitted development and a formal record of that is worth having. Daylight to neighbouring rooms and the amenity of adjoining gardens should be tested at design stage too, since terraced-house proposals are commonly weighed on both.
