Pimlico
Pimlico is one of central London's most architecturally uniform neighbourhoods a planned grid of
Georgian and early Victorian stucco terraces laid out by Thomas Cubitt in the 1830s and 1840s,
covering the area between Vauxhall Bridge Road and the Thames. Almost the entire neighbourhood
sits within Westminster's Pimlico Conservation Area, and a significant proportion of properties
are listed or fall within the curtilage of listed buildings. That means extending a home here
isn't simply a matter of checking permitted development limits it requires a properly prepared
planning application, often a Listed Building Consent application alongside it, and drawings
that demonstrate genuine sensitivity to the existing building character. Buildaway's team is
experienced in working within Westminster's conservation framework and structures every Pimlico
project around those requirements from the initial design stage.
The typical Pimlico townhouse presents specific opportunities for extension that differ from
other London property types. Most have an existing lower-ground floor level extending beneath
the rear garden, which creates scope for outward rear additions at that level without
significantly impacting the upper floors or the garden above. Return wings at the back of the
main house often contain unused or underutilised space that can be reconfigured or extended
outward. These are the extension types that work best within Pimlico's planning context and its
physical layout and they can genuinely transform how the ground and lower-ground floors function
without altering the street-facing character of the building at all. Buildaway designs around
what's achievable here rather than proposing schemes that won't survive Westminster's
scrutiny.
Building in Pimlico also involves practical challenges that don't apply in less central
locations. Access to rear gardens through narrow mews lanes or internal stairwells affects how
materials are delivered and how waste is removed. Scaffold licences, skip permits, and
contractor parking all require coordination with Westminster's highways team before work starts.
Neighbour relationships in these tightly packed terraces matter, and party wall procedures need
to be followed carefully given the shared structural walls on both sides. Buildaway manages all
of this as part of running the project permits, notices, logistics, and site management so the
build proceeds without avoidable friction and without putting you in a difficult position with
the council or adjoining owners.

What Our Pimlico Clients Say
Real reviews from our satisfied customers.
"We wanted to add a lower-ground rear extension to our Grade II listed townhouse on Warwick Square. Buildaway was fantastic. They navigated Westminster's Listed Building Consent process smoothly and handled the delicate structural underpinning without any issues. The new space is beautiful."
Sarah Henderson
Warwick Square, Pimlico SW1V
"Extending a Cubitt terrace in Pimlico comes with major access headaches. Buildaway managed all the Westminster scaffold licences, skip permits, and mews logistics perfectly. Our closet wing infill extension was completed on time, and the match with the original stucco is seamless."
David Miller
Lupus Street, Pimlico SW1V
"Excellent service from Cormac and his design team. They designed a gorgeous lower-ground rear extension that maximises natural light. They also handled the party wall agreements with both adjoining neighbours, which saved us so much stress. Highly recommend!"

Frequently Asked Questions
Your questions about home extensions in Pimlico, answered.
How much does a home extension cost in Pimlico?
Home extensions in Pimlico SW1V and SW1P typically start from £55,000 for a single-storey rear or lower-ground addition, rising to £120,000+ for double-storey or more complex structural projects. Westminster's central London rates apply here, and the Georgian and Victorian townhouse stock often requires specialist structural input that adds to the overall cost. Buildaway provides a fully itemised quote after a free site visit with no hidden figures.
Do I need planning permission for a home extension in Pimlico?
In most cases, yes. Pimlico sits almost entirely within Westminster's Pimlico Conservation Area, which removes standard permitted development rights for the majority of properties. Rear extensions, alterations to rear elevations, and any works visible from the street all require a full planning application to Westminster City Council. Many properties are also listed or curtilage-listed, adding a Listed Building Consent requirement on top. Buildaway handles the full application process including heritage statements and material justifications.
What types of home extensions are suitable for Pimlico properties?
Pimlico's grid of stucco-fronted terraces lends itself most naturally to lower-ground rear extensions, infill additions within existing return wings, and outward extensions at garden level. Full double-storey rear additions are harder to get through planning given Westminster's conservation policies, but well-designed single-storey and lower-ground extensions are regularly approved. Buildaway assesses each property individually and designs proposals that are realistic in both planning and structural terms.
How long does a home extension take in Pimlico?
Planning applications in Pimlico typically take 10–14 weeks for Westminster to determine, and longer if Listed Building Consent is also required. On-site construction for a lower-ground or single-storey rear extension runs 14–18 weeks once approvals are in place. Projects involving underpinning, steel frames, or complex party wall situations can extend that further. We set out a full programme at the start covering both planning and construction phases so you're working from accurate timelines throughout.
Does Buildaway manage party wall agreements for Pimlico extensions?
Yes. Pimlico's terraced townhouses share walls on both sides in most cases, and virtually any rear or lower-ground extension will trigger Party Wall Act requirements. Buildaway handles the full notice process identifying affected neighbours, serving the correct notices, and coordinating with party wall surveyors where needed. It runs alongside the planning and construction process rather than being left to the homeowner to sort independently.
Do you handle both design and construction for Pimlico home extensions?
Yes Buildaway manages the complete project in-house. Our architects produce drawings that meet Westminster's conservation area standards, our structural engineers handle all calculations including party wall and steelwork design, and our own trades carry out the full build. There's no separation between the design team and the contractor, which keeps the project on programme and ensures what's specified actually gets built.
Are Pimlico home extensions worth the investment?
Generally yes. Property values are strong across SW1V and SW1P, and a well-executed lower-ground or rear extension on a townhouse adds usable floor area that buyers value highly particularly for larger family homes close to central London. The planning process is more involved here than in outer boroughs, but the return on a quality build in this location is typically solid. Buildaway gives you an honest assessment of likely added value during the initial consultation.
