Architects in Putney for Extensions, Loft Conversions & Planning
From planning applications to structural design — we help Putney homeowners extend, convert and improve their homes.
Architectural Services in Putney
Putney sits on the south bank of the Thames in the London Borough of Wandsworth, known for its riverside setting, excellent schools and strong community feel. The area’s housing stock is predominantly Victorian and Edwardian — from the grand detached villas along Putney Hill to the terraced streets radiating from the Upper Richmond Road and Putney High Street. Families in Putney regularly choose to extend and convert their homes rather than move, making the most of properties with genuine architectural character.
Whether you are planning a house extension in Putney to create an open-plan kitchen-diner, a kitchen extension in Putney to transform your ground floor, a loft conversion to add a bedroom or home office, or a wraparound extension on a larger property, the design needs to work within Putney’s planning context. Several parts of the area fall within Wandsworth Council’s conservation areas, and the Thames Policy Area adds further design considerations for riverside properties.
We provide full architectural drawing packages, handle your planning permission application and deliver the building regulation documents your contractor needs to build with confidence. Every project begins with a detailed 3D measured survey and ends with a set of drawings tailored to your property and your ambitions. We also provide in-house structural engineering in Putney, delivering beam calculations and structural designs so you deal with one team — your Putney architects — from concept to completion. We also serve homeowners across neighbouring boroughs — see our pages for architects in Richmond, architects in Wandsworth, architects in Fulham, architects in Wimbledon and architects in Kingston.
Why Putney Projects Need Careful Planning
Putney sits within the London Borough of Wandsworth, which has over 45 conservation areas across the borough, several directly affecting Putney. Several of these directly affect Putney — including the Putney Embankment, West Putney and Roehampton conservation areas. If your property falls within one, permitted development in Putney may be restricted and external changes often require a full planning application.
Wandsworth Council applies Article 4 Directions in many conservation areas, removing rights to alter front elevations, windows, doors and boundary walls without consent. Even outside conservation areas, the council expects proposals to respect the scale and character of the street, particularly in Putney’s established Victorian and Edwardian residential roads.
Putney’s housing stock is predominantly Victorian and Edwardian terraces, with larger detached properties on Putney Hill and towards Roehampton. The proximity to the Thames and Putney Heath adds further planning considerations for some properties.
This is why choosing an architect with local experience matters. We understand Wandsworth Council’s expectations for Putney projects and design with these constraints in mind from day one — whether your project involves a house extension in Putney, a loft conversion in Putney or a rear extension in Putney.

Loft Conversions and Dormer Designs in Putney
A loft conversion in Putney is ideal — the area’s Victorian and Edwardian terraces and semi-detached homes are well suited to rear dormer conversions. A rear box dormer adds a full-sized bedroom and en suite bathroom in the roof space, typically without needing a planning application. For homes with hipped roofs — common on the Edwardian semis around Putney Heath and West Hill — a hip-to-gable conversion extends the usable loft width significantly.
L-shaped dormers are becoming increasingly popular in Putney, wrapping around the rear and side of the roof to maximise every square metre. This approach works particularly well on wider properties where a standard rear dormer alone would leave unusable space in the eaves.
As specialist loft conversion architects in Putney, we know that most rear dormer conversions fall within permitted development in Putney, provided they meet the size and material requirements. Properties in conservation areas — including parts of the Putney Embankment, East Putney and West Putney — may require planning permission for roof alterations. We assess your property’s specific status before starting any design work.
Victorian and Edwardian Extensions in Putney
Side Return Extensions
Reclaiming the narrow side passage on Victorian terraces around Putney's residential streets to create wider, open-plan ground floors with improved natural light.
Rear Extensions with Bifold Doors
Single storey rear extensions opening onto the garden through full-width glazing, creating seamless indoor-outdoor living spaces on Putney's family homes.
Wraparound Extensions
Combining side return and rear extensions for maximum ground floor space, particularly effective on end-of-terrace and wider semi-detached properties.
Rear Dormer Loft Conversions
Adding a rear box dormer to create a new bedroom, en suite or home office in the roof space without altering the front elevation.
Double Storey Extensions
Extending at ground and first floor simultaneously, popular on the larger semi-detached and detached properties around Putney Hill and West Hill.
Basement Conversions
Excavating beneath Victorian and Edwardian properties to add a full lower ground floor for a home cinema, gym or additional bedroom.
Planning Permission Support in Putney
Putney falls within the London Borough of Wandsworth, and Wandsworth Council manages all planning applications in the area. The council has a well-established approach to residential extensions and loft conversions, with clear expectations around design quality, neighbour impact and conservation area sensitivity.
Several parts of Putney are covered by conservation areas, including East Putney, West Putney and the Putney Embankment. Properties within these areas face additional restrictions on extensions, roof alterations and material changes. The Thames Policy Area also applies to riverside properties, adding further design considerations around flood risk, views and the public realm.
We prepare all planning drawings, design and access statements and supporting documents required for a householder planning application to Wandsworth Council. Where your project falls within permitted development, we prepare lawful development certificates. We understand what Wandsworth Council expects and design accordingly, reducing the risk of delays or refusal. Whether you need a design and build service in Putney or drawings for a new build in Putney, our architects manage the process from start to finish.

Areas We Cover in Wandsworth Borough
The commercial heart of Putney with a mix of Victorian terraces and period conversions on surrounding streets. Rear extensions and loft conversions are popular on the terraced housing stock. Some properties fall within the Putney Embankment conservation area.
Residential area with a strong concentration of Edwardian and Victorian semis and terraces. The West Putney conservation area applies to parts of this neighbourhood, requiring careful design for any external alterations. Side returns and loft conversions are the most common project types.
Larger detached and semi-detached properties set on generous plots. Projects tend to be more substantial here — double-storey extensions, basement conversions and full refurbishments. Proximity to Putney Heath brings additional green space considerations.
Mix of Victorian terraces and mansion flats close to East Putney station. Popular for rear extensions to create open-plan kitchen-diners. Narrow plots require thoughtful design to maximise natural light and avoid overlooking neighbours.
A mix of period properties and post-war housing, including the Roehampton Estate. The Roehampton conservation area covers parts of the historic village centre. Projects range from loft conversions on older properties to extensions on 1930s-era housing.
Streets running down towards the Thames with predominantly Victorian terraced housing. The Putney Embankment conservation area affects properties closest to the river. Rear and side extensions are common, with careful attention needed to flood risk zones.
Busy residential streets with a mix of Victorian terraces and Edwardian properties. High demand for loft conversions, rear extensions and open-plan living spaces. Good public transport links make this a popular family area where homeowners extend rather than move.

It depends on the size and your property's location. Many single-storey rear extensions fall under permitted development. Properties in Putney's conservation areas — including East Putney and West Putney — may need full planning permission. We check your property's specific status before starting any design work.
Construction costs for a single-storey rear extension typically sit around £2,500–£3,500 per square metre in Putney. Costs vary with specification and access. We provide clearer estimates after surveying your property.
Yes. Putney's Victorian terraces are well suited to rear dormer loft conversions, adding a bedroom and en suite without changing the front elevation. For hipped-roof properties, a hip-to-gable conversion unlocks significantly more usable space.
A side return extension reclaims the narrow passage alongside a Victorian terrace to widen the ground floor. It typically adds 1 to 2 metres of width, transforming a narrow kitchen into an open-plan kitchen-diner. It is one of the most popular and cost-effective improvements in Putney.
Yes. Our in-house structural engineers handle beam calculations, steelwork and foundation design without you needing a separate engineer. This saves time and avoids coordination delays between consultants.
From initial consultation to a planning decision, expect 10 to 14 weeks including the survey, design development and the statutory determination period. Permitted development projects are usually faster.
Yes, but permitted development rights may be restricted. Extensions in conservation areas usually need a full planning application. We design proposals that respect the conservation area character while meeting your space requirements.
Most extensions on Victorian terraces involve work on or near a shared party wall, so an agreement is usually required. We advise on the requirements and can recommend experienced party wall surveyors who work across Wandsworth.
Yes, basement conversions are possible on many Putney properties. Wandsworth Council requires careful consideration of structural impact, drainage and construction management. We coordinate the design and application process alongside specialist basement contractors.
Yes. We review the decision notice, identify the reasons for refusal and redesign the scheme to address those issues. Many refusals can be overcome with a more carefully considered design approach.
Yes. Our in-house construction team can build your project from start to finish. One team manages everything from initial survey through to completion, so nothing is lost between design and build.
