FAQ

An interior architect designs and reshapes spaces. They focus on making them functional, beautiful, and comfortable. They also ensure that the structures remain safe and strong.

They do more than decorate. They design spaces and structures and add features like heating, cooling, insulation, and acoustics.

Their work is about optimising layouts, increasing spatial efficiency, and selecting quality materials. This creates cohesive and balanced spaces. Interior architects handle technical details such as building codes, sustainability, and material strength.

This ensures spaces are practical and look great.
They team up with engineers, contractors, and interior designers to design stylish, comfy spaces. Their goal is to combine innovation and comfort for a great experience. They can move homes and businesses. So, every design choice boosts usability, energy efficiency, and durability.

An architect and an interior architect are not the same, though their work overlaps in some areas. An architect designs buildings. They focus on the overall look and structure.

Their work includes exteriors, load-bearing parts, and planning rules. They manage all aspects, from the building’s foundation to its roof.

This keeps it safe and fitting for its environment. An interior architect works on enhancing indoor spaces. They focus on space planning and reconfiguring. They also integrate heating, cooling, acoustics, insulation, and material finishes. This work improves usability and comfort.

An architect focuses on the building’s shell. Meanwhile, an interior architect designs the inside to be functional and stylish. They work with the existing structure to create a unified and effective space.

Yes, an interior architect can do interior design. But their role goes beyond just picking furniture and colours. Interior designers focus on how a space looks and feels. They work on décor, lighting, and layout. In contrast, interior architects handle the larger vision. They rethink layouts and adjust structures. They also integrate key systems like heating, cooling, soundproofing, and insulation.

This makes the space beautiful and comfortable. They use top-quality materials, custom finishes, and smart layouts. This creates spaces that are visually appealing and operate effectively. An interior architect can handle interior design, but their skills run deeper. They shape how a space feels, works, and endures over time.

We’ve tackled interior architecture projects all over London. We’ve fixed up heritage properties in Westminster, built high-density homes in Southwark, and converted warehouses into houses in Hackney. Borough policies affect how we reconfigure, service, and approve interior spaces.

Lessons Learned About Space Heating, Materials And Acoustics

1. Space Reconfiguration Isn’t Just a Design Decision — It’s a Regulatory One
Many of our projects start with a wish to rethink interior spaces. This could mean: opening a kitchen-dining area, separating bedrooms, or changing a loft. In boroughs like Camden or Islington, reconfiguring spaces often needs planning approval. This is especially true in conservation areas or when floor space standards are in place.

In places like Kensington & Chelsea (Google Maps), changing a property’s layout or structure can trigger planning notifications. This can happen even if there are no changes to the exterior. We work with planning officers early.

This helps ensure our layout proposals meet Building Control standards. It also supports escape routes and access to natural light from the first draft.

2. Heating, Cooling, and Ventilation Are Central to Interior Architecture in Dense Boroughs
In boroughs like Lambeth and Lewisham, high-density living is common. So, it’s important to provide interior spaces with good heating and cooling systems.

Interior architecture should consider thermal zoning, insulation, and airflow from the beginning. This matters a lot for retrofit projects or older homes with poor cavity insulation.

We met the borough’s expectations by designing interiors with hidden vents. We also included underfloor heating and smart zoning. This design keeps aesthetics and comfort intact.


3. Material and Finish Selection Has Policy Implications
Boroughs are now more focused on the materials used inside homes. This shift comes as finishes may seem like the last step. They are responding to the sustainability goals set by the London Plan.
For example, in Hackney (Google Maps) and Southwark, sustainable refurbishment is a high priority. This includes using low-VOC paints, local materials, and finishes with low embodied carbon. At Payte, we always include these factors in our interior architecture strategies. We do this not only to meet planning needs but also to make interiors healthier and more durable.


4. Acoustic and Insulation Design Is a Top Priority in Boroughs with Flats and Conversions
In boroughs with dense housing like Tower Hamlets or Brent, interior design faces challenges. Acoustic separation and fire compartmentalisation are crucial, especially in subdivided or converted buildings.
We’ve completed many flat renovations and interior remodelling projects. Planning teams needed proof that the party wall upgrades, insulation solutions, and floor build-ups met Approved Document E. We use special materials and smart layout planning for our acoustic design to achieve this. This way, neighbours aren’t disturbed, and borough officers are happy.

How Payte Architects Is Future-Proofing Interior Architecture Projects

1. Better Early Engagement with Planning Departments
We often begin our interior architecture projects with pre-application planning advice meetings. This is especially true in sensitive areas like Hampstead or Notting Hill. This helps us see how each borough interprets the interior change policy. This way, we can avoid costly delays later.

2. Whole-Home Thinking — Even When Only the Interiors Are Changing
London councils want to see how small design changes can boost sustainability and adaptability. We show how our plans improve daylight access, thermal comfort, and air quality. It’s not just about layout or visual flow.

In a recent project in Clapham, we swapped the kitchen and lounge. This change greatly improved cross ventilation, daylight, and family access. All these factors helped us succeed in planning.

3. Staying Ahead of the London Plan and Borough Policies
We keep an eye on policy updates from councils like Westminster (Google Maps) and the Greater London Authority. This makes sure our interior design follows the latest standards for energy use, accessibility, and net-zero readiness.

Final Thoughts: Interior Architecture is Local, Strategic, and Emotional

Interior architecture goes beyond just the inside of a building. It’s about the lived environment and the space between structure and experience. In London, each borough has its own priorities and planning style. Knowing the rules is key. Design for wellbeing, and create interiors that follow policies.

At Payte Architects London, we view each borough’s rules as guides, not limits. They help us create more thoughtful designs.

Our process is based on respect. We value the building’s structure, the existing rules, and the future residents. This applies whether we’re redesigning a flat in Islington or renovating in Camden.

At Payte Architects, we believe interior architecture goes beyond layout and appearance. It’s about the feelings a space creates. When you enter a room and feel warm, welcoming, and grounded, it’s not just about good insulation or heating. The materials and finishes play a subtle but important role, too.

We call it tactile warmth. It’s the comforting feeling of physical and emotional warmth. This feeling often comes from careful architectural choices.

In a city like London, with its cool, grey, and damp climate most of the year, warmth matters. It’s not just about comfort; it’s about feelings too. In our London work, from historic Hampstead to industrial Hackney, we’ve seen how materials and finishes help with passive heating. They also enhance the daily experience of a space.

Why Tactile Warmth Matters in Interior Architecture

Tactile warmth is often underestimated in design conversations. It’s easy to focus on visuals, but touch, including temperature and texture, is just as strong. At Payte, we focus on a sensory approach. This helps materials add to both the physical comfort and the emotional feel of a space.

Passive heating uses a building’s design to hold, absorb, and share heat naturally, without machines. Materials are key here. They insulate and prevent heat loss. They also store warmth from the surroundings and release it slowly.

But beyond performance, they shape how we relate to a room. Cold, shiny surfaces can feel unwelcoming in winter. In contrast, matte, natural, or textured finishes make a room feel warm and inviting. They encourage touch and create a sense of cosiness that no thermostat can match.

Materials for Passive Heating and Tactile Warmth

In our London projects, we choose materials and finishes that are thermally smart and also emotionally appealing.

1. Timber
Timber is a cornerstone of tactile warmth. Its low thermal conductivity makes it slow to lose heat, meaning it stays warm to the touch. We use oak, ash, or Douglas fir for flooring, wall panelling, and ceiling cladding. These materials add warmth to interiors, both literally and figuratively.

In areas like Belsize Park and Highgate, clients often seek subtle luxury in historic homes. Timber connects the old and new beautifully. It adds depth, warmth, and texture without overpowering the architectural envelope.

2. Natural Stone with Thermal Mass
Stone is excellent for absorbing and storing heat during the day and releasing it gradually — a key principle in passive solar design. In places like Peckham or Southbank, south-facing homes receive plenty of light.

We often suggest using limestone or terrazzo with light finishes. This choice boosts heat storage and adds to the home’s beauty.

Combining stone flooring with underfloor heating gives you the best of both worlds. You enjoy warmth in winter and a cool, luxurious feel in summer.

3. Clay and Lime Plasters
Natural plasters, such as clay or lime, are different from regular gypsum. They are breathable, helping with thermal and moisture regulation.

We use these finishes in spaces that need a “soft” look and feel. They fit nicely in bedrooms or meditation rooms, especially in homes in Notting Hill and Stoke Newington.

These finishes do more than control room temperature; they also shape our feelings. They encourage us to slow down and invite stillness.

4. Textiles and Soft Finishes
Upholstery, wall hangings, and acoustic panels made from wool, felt, or cork can help a room retain heat. They might not always be the main materials in architecture, but they have a big impact.

In homes in Dalston or Finsbury Park, energy efficiency matters a lot. So, we often use these materials in the design, not just for decoration.

Where in London This Matters Most

Some areas of London face unique climate or building challenges. This makes tactile warmth and passive heating even more crucial.

Historic Homes in Hampstead & Chelsea

Older homes in these areas often have drafts, cold brick walls, and single-glazed windows. High-performance finishes, such as insulated timber panelling and lime plaster walls, help maintain the home’s heritage. It also greatly boosts thermal performance.

Warehouse Conversions in Shoreditch & Clerkenwell

Large, open-plan spaces with concrete and steel can feel cold and echoey. This happens when material choices aren’t carefully considered. In these projects, we use timber flooring, wool acoustic panels, and soft furnishings. These elements warm the space, making it cozier both in temperature and sound.

New Builds in Battersea & Hackney Wick

Modern homes often have great insulation and heating. Still, they can feel cold and sterile. We use tactile finishes such as timber, textured tile, matte wall paint, and layered materials. These create intimacy and a feeling of being grounded.

The Human Side of Interior Architecture

This approach focuses on a very human need: to feel safe, comfortable, and connected in our spaces. Passive heating strategies using tactile materials do more than save energy. They also make us feel at home.

We often hear from clients that they want their homes to feel “calm” or “restorative.” That doesn’t happen through colour palettes alone — it happens through touch. A timber handrail, a textured wall finish, a warm-to-the-foot floor.

These elements register with us even if we’re not consciously noticing them — and that’s exactly the point.

Sustainability Through Material Intelligence

There’s also an environmental dimension. Passive strategies can help reduce emissions, lower bills, and cut reliance on artificial systems. This is better than simply turning up the heating. We see this as a long-term investment in sustainable design that’s also better for people.

Using materials with high thermal mass or insulation makes our homes and interiors efficient, comfy, and strong. Strategic spatial planning also plays a key role in this process.
