Paddington
Paddington occupies a stretch of central west London where the built environment shifts
considerably within a short distance from the grand stucco squares and terraces around Hyde
Park and Bayswater Road to the denser, more varied streets north of the station toward
Westbourne Park and Queen's Park. The older residential sections of W2, particularly around
Gloucester Square, Sussex Gardens, and Westbourne Terrace, are almost entirely covered by
Westminster's conservation area designations, with a significant proportion of properties
carrying listed status. Extending a home in this part of Paddington means engaging with
Westminster City Council's planning framework from the very beginning permitted development is
not an option across most of the stock, and even modest rear works require properly prepared
applications with supporting heritage documentation. Buildaway's architects are familiar with
what Westminster's conservation officers expect and structure submissions accordingly.
The physical layout of Paddington's Victorian townhouses creates both constraints and
opportunities that differ from other London property types. Most have four or five storeys
including a lower-ground level, with rear gardens accessed either directly from the
lower-ground floor or via side passageways. That lower-ground connection is the key to how
these properties can be extended most effectively outward additions at that level bring in
natural light from the rear garden while keeping the extension largely out of view from the
street, which aligns well with what Westminster will typically approve. Return wing spaces at
the back of the main house also offer scope for infill additions that add floor area without
altering the primary elevation. Buildaway designs within these parameters rather than producing
schemes that won't clear the planning process.
North of the station, toward Praed Street and the Harrow Road corridor, the housing stock
changes character a mix of late Victorian terraces, post-war council blocks, and more recent
residential developments sits alongside the older townhouses. Properties in this part of
Paddington often fall within different planning zones and have different structural profiles,
with some sitting on shallower foundations and others built with later 20th-century methods.
Buildaway surveys every property before producing a design, checking foundation depth, drainage
routing, structural wall configurations, and any restrictive covenants that might affect what
can be built. The quote and programme you receive reflect the actual site rather than a generic
template.

What Our Paddington Clients Say
Real reviews from our satisfied customers.
"We wanted a lower-ground rear extension done on our Sussex Gardens townhouse and after meeting with several builders, I decided to go with Buildaway. From my first contact with Cormac, I was in good hands. His team navigated Westminster's Listed Building Consent process seamlessly and the new lower-ground space is stunning."
Sarah Henderson
Sussex Gardens, Paddington W2
"It was an absolute pleasure working with Cormac and the Buildaway team on our Westbourne Terrace Victorian townhouse closet wing infill. Greg is an absolute star. Cormac's communication and advice was excellent, and the planning submission to Westminster went through without a hitch. A truly great team."
David Miller
Westbourne Terrace, Paddington W2
"Cormac & his team were brilliant throughout our Paddington W2 lower-ground extension project. From scoping to completion, Cormac was always responsive, helping us navigate the Gloucester Square Conservation Area requirements and coordinating party wall procedures with both neighbours. His team worked extremely hard and Greg's attention to detail was exceptional."
Clara Sterling
Gloucester Square, Paddington W2
"We've had a genuinely fantastic experience with Buildaway. Cormac was ultra responsive and excellent at communicating throughout our full townhouse refurbishment and lower-ground extension near Little Venice. The in-house team model works brilliantly architects and builders under one roof kept everything on track. Exceptional craftmanship throughout."
Robert Davies
Little Venice, Paddington W9
"Buildaway did a wonderful job with our Praed Street Victorian terrace rear extension. They were incredibly professional, clean, and respectful of our neighbours throughout. The pricing was completely transparent from start to finish no unexpected additions and the quality of the finished extension is outstanding."
Emily Watson
Praed Street, Paddington W2
"From the initial design drawings to the final lick of paint on our Hyde Park Gardens townhouse, Cormac and the team were superb. They understood exactly what Westminster's conservation officers would accept and designed an extension that was approved on first submission. The project management was flawless throughout."
James Thorne

Frequently Asked Questions
Your questions about home extensions in Paddington, answered.
How much does a home extension cost in Paddington?
Home extensions in Paddington W2 typically start from £55,000 for a single-storey rear or lower-ground addition, with double-storey projects ranging from £95,000 to £125,000+. Paddington falls under Westminster City Council, so labour rates, material standards, and logistical costs reflect a central London borough. The specific layout of your property whether it has an existing lower-ground level, shared party walls on both sides, or restricted rear access all shape the final figure. Buildaway provides a fully itemised quote following a free site assessment, with no costs added later that weren't in the original breakdown.
Do I need planning permission for a home extension in Paddington?
Most Paddington properties will need a planning application rather than relying on permitted development. The area contains several conservation designations including the Bayswater and Gloucester Square Conservation Areas and Westminster removes permitted development rights across much of its residential stock. Victorian and Edwardian stucco townhouses along Sussex Gardens, Westbourne Terrace, and surrounding streets typically require a full householder application. Some properties are also listed, which adds a Listed Building Consent requirement. Buildaway establishes the correct planning route for your property from the outset and manages the full submission process.
What types of extensions work for Paddington properties?
Paddington's housing stock is largely made up of mid-to-late Victorian stucco terraces and townhouses, many of which have lower-ground floors with access onto rear gardens or light wells. Rear extensions at lower-ground level are the most practical and planning-compatible option for most of these homes. Return wing infills and reconfigured lower-ground layouts also work well where the existing footprint allows. Full double-storey rear additions are harder to push through Westminster planning in conservation-sensitive streets, so Buildaway designs proposals based on what the council is genuinely likely to approve for your specific plot.
How long does a home extension take in Paddington?
Westminster's planning team typically takes 10–14 weeks to determine a householder application in Paddington, and longer where Listed Building Consent runs alongside it or where the council requests further information. Once on site, a lower-ground or single-storey rear extension generally takes 14–16 weeks to complete. Projects with more complex structural requirements steel frames, underpinning near shared foundations, or significant drainage rerouting can run to 18–20 weeks. Buildaway maps out the full programme at the start, covering both pre-construction and build phases, so you're not surprised by the overall length of the project.
Does Buildaway handle party wall procedures for Paddington extensions?
Yes. Paddington's terraced townhouses almost universally share structural walls with neighbours on both sides, and any rear or lower-ground extension will bring the Party Wall Act into play. Buildaway manages this as part of the standard project process identifying which adjoining owners need to be notified, preparing and serving the correct notices within the required timeframes, and coordinating with party wall surveyors where a formal award needs to be drawn up. It runs in parallel with the planning process rather than being left until after approval is granted.
Do you cover both design and construction for Paddington home extensions?
Yes everything goes through Buildaway directly. Our architects produce drawings calibrated to Westminster's conservation requirements, our engineers handle all structural and party wall calculations, and our own trades deliver the build from groundworks to finishing. Paddington extensions often involve detailed coordination between heritage design requirements and the structural realities of working in Victorian townhouses, and having the same team across both disciplines means those decisions get made consistently rather than getting lost between separate firms.
How does building in Paddington compare to other London locations?
Paddington sits in Westminster, which means stricter planning controls, higher build costs, and more administrative requirements around site logistics than most outer London boroughs. Scaffold licences, skip permits, and contractor access all need to be arranged with Westminster's highways team in advance. That said, property values across W2 are strong, and a well-executed rear or lower-ground extension adds meaningful floor area in a location where buyers consistently pay a premium for larger homes. Buildaway factors the Westminster-specific requirements into every quote and programme from the beginning so they don't become surprises mid-project.
