Hammersmith and Fulham residential architects
Architect advice for period homes, conservation-area properties, extensions and retrofit in Hammersmith and Fulham
Hammersmith and Fulham has many older, altered and conservation-sensitive homes. A rear extension, roof alteration, flat reconfiguration, retrofit upgrade or basement idea can look straightforward at first, but the best route often depends on the house, the street, the neighbours and the planning context around it.
As Hammersmith and Fulham residential architects, GOAStudio helps homeowners test ideas before the project gathers pace. We advise on extensions, renovations, roof alterations, flats and maisonettes, conservation-area homes, older-home upgrades, retrofit and green alterations, and architect advice before buying a house to renovate.
The aim is simple: to help you understand whether the idea suits the property, where the risks are likely to sit, and whether there is a better way to get the result you want.
Many clients start with a Feasibility Review or Home Consultation so they can understand the property before committing to drawings, a purchase or a larger design stage.

Why homeowners in Hammersmith and Fulham come to GOAStudio
A realistic view before decisions become expensive
Many homes in Hammersmith and Fulham have potential, but that potential is not always obvious from a first viewing or a simple sketch. Extension depth, roof form, neighbouring outlook, garden space, retrofit potential and conservation-area controls often need to be checked while there is still time to adjust the brief.
Design that suits the house, flat or terrace
Your home may be judged as part of a terrace, building group or conservation-area street, not just as a single property. We look at how the building works now, what gives it character, and how new work can improve daily life without feeling forced onto the house.
As architects in Hammersmith and Fulham, we often help clients compare what they want to do with what the property, planning context and budget are likely to support.
Older-home, conservation and retrofit experience
GOAStudio has experience with older London homes, conservation-sensitive design and retrofit. In this borough, that matters because many projects involve traditional construction, rooflines, planted front gardens, rear additions, neighbouring properties and the need to make homes warmer, healthier and more efficient.
Useful Hammersmith and Fulham council guidance
The following Hammersmith and Fulham Council documents may be useful if you are planning work to a house, flat or maisonette in the borough:
• Planning Guidance Supplementary Planning Document, February 2018 — detailed guidance on housing standards, rear extensions, conservation areas, Buildings of Merit, basements, lightwells, balconies, terraces, privacy, outlook, noise, air quality, SuDS, flood risk and waste storage. This is the most useful practical council source for many homeowner projects.
• Hammersmith and Fulham Local Plan, February 2018 — the borough-wide planning framework, including policies and context on housing, regeneration, design, conservation, the River Thames, flood risk, environmental sustainability and local character.
• Climate Change Supplementary Planning Document, October 2023 — guidance on retrofitting homes, low-carbon heating, solar panels, insulation, overheating, ventilation, green infrastructure, biodiversity, flooding and sustainable drainage. This is especially relevant for older-home upgrades and greener alterations.
For homeowners, these documents are useful background, but they are not always easy to apply to a specific property. GOAStudio can help interpret the relevant guidance in relation to your house, flat, terrace, conservation-area setting, retrofit aims and budget.
What makes projects in Hammersmith and Fulham different
Residential projects in Hammersmith and Fulham vary widely because Fulham terraces, Shepherd’s Bush conservation-area houses, Brook Green flats, Stamford Brook family homes and riverside properties can all raise different design questions.
The borough’s Local Plan describes Hammersmith and Fulham as an inner London borough with a long Thames frontage, distinct areas including Fulham, Hammersmith and Shepherd’s Bush, protected historic environments and major regeneration areas.
For homeowners, the practical point is this: the same rear extension, roof change or solar installation can be straightforward on one property and difficult on another, depending on the street, neighbours and conservation context.
This is why early advice is useful. It helps you understand how the property is likely to be viewed before drawings, costs and expectations move too far in one direction.

Name and origin
Hammersmith has disputed origins as a place name. Some sources suggest it derives from Hammoder’s Hythe (a safe haven belonging to Hammoder), others, perhaps more satisfyingly, suggest it’s simply a concatenation of ‘hammer’ and ‘smithy’, denoting an area important for metal working. Fulham is an area belonging to an Anglo-Saxon called Fulla, but rather than the usual ‘ham’ meaning homestead, this one was originally ‘hamm’, signifying a bend in the river. [Londonist.com]
Hammersmith and Fulham planning department
You will probably need planning permission if you want to build something new, make a major change to your home – e.g. building an extension, or change the use of your property. There are different rules depending on what you want to do and the relevant planning policy that applies to your property.
At GOAStudio we have a great record of dealing with the local authority planners and building control inspectors and we are on hand to assist with your application and successfully handle every stage of your project.
When a proposal requires a planning application GOAStudio’s architectural planning service can take it from early design and local-policy review through to submission and council liaison.

Buying a house to renovate in Hammersmith and Fulham
Buying a house to renovate in Hammersmith and Fulham often benefits from architect advice before you make an offer or commit to the purchase.
A property may look full of potential. You may see space for a rear extension, a roof conversion, a better kitchen and garden connection, a flat reconfiguration or a deeper retrofit. But the important questions usually come after the first viewing.
Is the property in a conservation area? Is it a Building of Merit? Is the rear garden deep enough? Would a roof alteration affect the wider terrace? Can the home be made warmer without creating moisture or ventilation problems? Is a basement or lower-ground-floor idea realistic? Would the likely planning complexity still make the purchase worthwhile?
GOAStudio provides architect advice before buying a house to renovate in Hammersmith and Fulham and across London. We can help you test whether the property is right for the project you have in mind.
This is especially useful for older houses, flats and maisonettes in Fulham, Hammersmith, Shepherd’s Bush, Stamford Brook, Barons Court, Brook Green and West Kensington, where the same idea can vary significantly from one property to another.
A Feasibility Review can help you decide whether to proceed, rethink the brief, ask for more information, or walk away before costs begin to build.
Period and conservation-area homes in Hammersmith and Fulham
Period and conservation-area homes in Hammersmith and Fulham can often be extended or upgraded, but the design needs to suit the house, the terrace and the wider street.
The borough has many nineteenth- and early twentieth-century homes, including terraces and groups of buildings where the rhythm of the street, roofline, windows, front boundaries and rear additions all contribute to local character. The Planning Guidance SPD notes that many residential areas of consistent design and high architectural quality sit within conservation areas, with the street often providing the scale and setting for uniform terraces.
This may affect:
• rear and side extensions;
• roof alterations, dormers, mansards and rooflights;
• windows, doors and external openings;
• chimneys and roofline details;
• front gardens, railings and boundaries;
• visible external additions, including balconies, terraces, solar panels, heat pumps;
• works to Buildings of Merit or locally distinctive buildings.
Buildings of Merit are particularly important in Hammersmith and Fulham. They are locally valued heritage buildings, and proposals affecting them should respect their scale, character and materials. The council’s guidance also notes that terraces, parades and groups of buildings can have townscape value greater than the individual importance of each building.
Extensions, renovations and flat alterations
Many Hammersmith and Fulham extensions are shaped by the original back addition, garden depth, neighbouring outlook and whether the property sits in a conservation area.
For most homeowners, the aim is not just more floor area. It is about more light, better flow, improved comfort, useful storage, a stronger connection to the garden, or a layout that better suits family life.
Rear and side extensions
Rear and side extensions are common in Hammersmith and Fulham, especially to Victorian and Edwardian houses. The key questions are usually about depth, height, garden space, neighbouring windows and how the extension relates to the original rear form of the house.
If you are looking for a house extension architect in Hammersmith and Fulham, the useful starting point is not just the size of the extension, but how it affects the house, garden and neighbours.
The Planning Guidance SPD gives detailed guidance on rear extensions, including extension depth, distance to the rear boundary and the amount of original rear open area covered. We translate that into a practical early test: does the proposal give you a better home without creating avoidable problems for the neighbours, garden or planning application?
Roof alterations, mansards and terraces
Roof alterations can be valuable, but they often need careful handling. A mansard alteration, rooflight, dormer, terrace or maintenance access can affect the wider roofline, neighbouring privacy and the character of a conservation-area street.
The question is not only whether the roof space exists. It is whether the change can be made in a way that sits comfortably with the host building and the surrounding group.
Flats, maisonettes and mixed-use buildings
Flats and maisonettes often involve more constraints than homeowners expect. Leasehold arrangements, neighbouring properties, access, structure, roof form, noise, privacy and mixed-use history can all affect what is practical.
Our Stamford Brook W12 flat extension project is a useful example. It involved a rear first-floor and roof extension to an upper-floor flat, alongside refurbishment of the commercial unit below to create a four-bedroom maisonette.
Internal reconfiguration and family homes
Sometimes the best improvement comes from reorganising what is already there. Better circulation, daylight, bathrooms, utility space, storage, kitchen/living arrangements and garden access can make a house or flat feel far more usable.
Our Stamford Brook W6 house extension and renovation project is an example of this. The original semi-detached house had poor-quality rear and side extensions that affected weather-tightness and blocked the relationship between the reception rooms and garden.
Retrofitting and green alterations to older homes
Retrofitting an older home in Hammersmith and Fulham needs joined-up thinking about insulation, ventilation, moisture, overheating, heating systems and planning constraints.
GOAStudio provides retrofit advice for older homes in Hammersmith and Fulham, especially where insulation, ventilation, solar panels, heat pumps or conservation-area constraints need to be considered together. For many homeowners, the goal is a warmer, healthier, more comfortable home with lower energy demand and fewer long-term risks.
Depending on the property, this may include:
• improving insulation carefully;
• reducing draughts and heat loss;
• upgrading or repairing windows;
• considering secondary glazing where appropriate;
• improving ventilation and reducing condensation risk;
• understanding moisture movement in older walls and floors;
• assessing solar panels where they can be integrated discreetly;
• considering heat pumps where location, noise and visual impact can be managed;
• using planting, permeable surfaces, green roofs or rainwater measures to improve resilience.
The council’s Climate Change SPD supports retrofitting where proportionate measures improve energy efficiency, comfort, healthy internal environments and climate resilience. It also recommends a whole-building approach, looking at all parts of the building together.
Done well, retrofit can improve comfort and long-term value. Done badly, it can create condensation, overheating or fabric problems that are expensive to undo. The same SPD highlights ventilation and overheating risks, passive ventilation, green infrastructure and the need to manage overheating without relying unnecessarily on energy-intensive air conditioning.
This is particularly important in older homes. Insulation can change how moisture moves through walls. Airtightness can affect ventilation. Large areas of glazing can improve light but increase overheating. Solar panels or heat pumps may be possible, but their location and appearance need thought, especially in conservation areas.
Our Fulham Broadway SW6 flat alterations and mansard roof project shows how greener upgrades can be integrated with roof-level work. The scheme included solar panels positioned low on the rear/south part of the roof, with access and handrail details designed to reduce visibility from the street and nearby windows.
Basements, lightwells and flood risk
Basements and lightwells in Hammersmith and Fulham can be sensitive because they may affect front gardens, drainage, flood risk, construction impact and the character of the street.
A basement may seem like a useful way to gain space where the house or garden is constrained. But it is not always the best or simplest answer. Early advice can help test whether the idea is proportionate, whether the costs and risks are justified, and whether another design route would give better value.
The issues can include:
• loss of planted front garden or boundary character;
• size and visibility of a lightwell;
• effect on rear garden space;
• structural works and construction disruption;
• drainage, groundwater and sewer flooding;
• neighbour concerns;
• conservation-area or Building of Merit constraints.
The Planning Guidance SPD notes that over-large or visible front lightwells can harm the appearance of an area, especially where they take up a large part of a front garden or remove planted frontage. The Local Plan also sets out limits and considerations for basement works, including garden area, depth, drainage, groundwater, SuDS, planting and flood risk.
GOAStudio can help you decide whether a basement or lightwell is worth pursuing, or whether a more modest extension, reconfiguration or retrofit strategy would be a better route.
Talk to us about your Hammersmith and Fulham home
Planning work to a Hammersmith and Fulham home often starts with a simple question: what is realistic for this property?
GOAStudio can help you answer that early, whether you are considering an extension, renovation, retrofit, roof alteration, flat reconfiguration, basement idea or possible purchase.

Selected Hammersmith and Fulham projects
Stamford Brook, W6 | House extension and renovation
This project is useful proof of GOAStudio’s experience with older-home renovation and carefully judged family-house extensions.
The house had been altered by previous owners and included poor-quality rear and side additions. GOAStudio replaced and reorganised these areas, improved the relationship between the reception spaces and the garden, and helped create a more practical family home.
It is relevant for homeowners who know their house has potential, but need advice on how to unlock it without repeating the mistakes of earlier alterations.
Stamford Brook, W12 | Flat extension and maisonette work
This project ahows GOAStudio’s experience with flat extensions, maisonette reconfiguration and mixed-use building context.
The work involved a rear first-floor and roof extension to an upper-floor flat, together with refurbishment of a ground-floor commercial unit to create a four-bedroom maisonette.
It is relevant for flat owners, leaseholders and homeowners considering upper-floor changes where structure, access, neighbouring properties and planning all need to be coordinated.
Shepherd’s Bush, W14 | Rear, side and roof extension
This project is useful proof of GOAStudio’s experience with conservation-area terrace work in Hammersmith and Fulham.
The scheme involved rear, side and roof extensions to a terraced house in a conservation area, together with full refurbishment and internal alterations. The design included reinstatement of original features, a double-height internal space, a first-floor office pod and a better connection between the lower-ground living areas and the rear garden.
It is relevant for homeowners who want to improve a period terrace without losing the qualities that make the house worth improving.
Fulham Broadway, SW6 | Flat alterations and mansard roof
This project is useful proof of GOAStudio’s experience with roof-level alterations, flat improvements and discreet green upgrades.
The scheme involved alterations to rear window openings, a Juliet balcony, maintenance access to the roof, a long rooflight and solar panels positioned carefully on the rear/south part of the roof.
It shows how practical improvements, roof access and renewable technology can be considered together, rather than treated as separate add-ons.
What homeowners often underestimate in Hammersmith and Fulham
Homeowners often underestimate how quickly a simple idea can become property-specific in Hammersmith and Fulham.
Common surprises include:
• a rear extension being limited by garden depth or neighbouring outlook;
• a roof alteration being affected by the wider terrace or conservation area;
• a flat or maisonette needing more careful planning than a whole house;
• a Building of Merit affecting external changes even where the building is not listed;
• a terrace or balcony creating privacy, overlooking or noise concerns;
• retrofit creating ventilation, moisture or overheating risks if considered in isolation;
• a front lightwell removing too much planted garden character;
• a basement raising flood, drainage, construction and neighbour issues.
What usually helps in Hammersmith and Fulham
The following usually helps a proposal feel more credible with the planners:
• extensions that follow the logic of the existing house or terrace;
• additions that remain secondary to the original building;
• roof changes that respect the wider roofline;
• materials and details that suit the host building;
• retention or reinstatement of original features where they matter;
• planted front gardens and retained soft landscaping;
• retrofit measures coordinated with fabric, ventilation and moisture;
• early advice while there is still time to adjust the brief.
What tends to trigger resistance
The following can make a project harder:
• oversized rear additions;
• loss of too much garden space;
• intrusive roof terraces or balconies;
• roof changes that disrupt terrace uniformity;
• visible external plant in sensitive locations;
• front lightwells that dominate the garden or street;
• unsympathetic windows, doors or external materials;
• retrofit upgrades that ignore heritage, moisture or overheating risk;
• basement proposals that underestimate drainage, flood or construction issues.
Hammersmith and Fulham architect FAQ
Do I need permission for a house extension in Hammersmith and Fulham?
You may do. Some house extensions can fall under permitted development, but many projects need planning permission, especially where the property is in a conservation area, has already been extended, affects neighbours, or involves roof, terrace, basement or external changes.
Can I extend a Victorian or Edwardian terrace in Hammersmith and Fulham?
Often, yes, but the design needs to respond to the original house, the back addition, garden depth, neighbouring outlook and the wider terrace. Rear, side and roof extensions all need to be judged carefully, especially in conservation areas.
Can I alter a conservation-area home in Hammersmith and Fulham?
Yes, but alterations to conservation-area homes usually need a more careful design approach. Windows, roof forms, front gardens, boundaries, lightwells, external equipment and visible alterations can all affect the character of the area.
What is a Building of Merit and does it affect my project?
A Building of Merit is a locally important heritage building. It is not the same as a listed building, but it can still affect what alterations are acceptable. External changes usually need to respect the building’s scale, character and materials.
Can I speak to an architect before buying a house to renovate in Hammersmith and Fulham?
Yes. GOAStudio provides architect advice before buying a house to renovate in Hammersmith and Fulham and across London. This can help you understand planning risk, design potential, likely constraints and whether the property suits your plans.
Are roof extensions or mansards possible in Hammersmith and Fulham?
Sometimes, but they need to be assessed in relation to the host building, the wider roofline, neighbouring properties and conservation-area context. Roof terraces, rooflights, dormers, mansards and changes to chimneys or roof slopes can all be sensitive.
Can I add solar panels, insulation or a heat pump to an older home in Hammersmith and Fulham?
Often, yes, but the right approach depends on the building. Insulation, ventilation, heating, solar panels and external equipment need to be considered together, especially in older homes and conservation-area settings. See our guide to upgrading an older London home for more on this approach.
Are basements and lightwells difficult to get approved in Hammersmith and Fulham?
They can be. Basements and lightwells may raise issues around garden character, visibility, drainage, flooding, groundwater, construction impact and neighbours. Early advice can help test whether the idea is realistic before design work goes too far.
Can GOAStudio help with flats and maisonettes as well as houses?
Yes. GOAStudio works on houses, flats and maisonettes. In Hammersmith and Fulham, this can include flat extensions, upper-floor alterations, mansard roof changes, mixed-use building reconfiguration and carefully judged external changes.
What is the best first step?
The best first step is usually a Feasibility Review or a Home Consultation. A Feasibility Review is useful if you want an early view of the opportunity and constraints. A Home Consultation is better if you want detailed advice on a specific property and project.
