Designing for Flow and Longevity: Inside a Thoughtfully Resolved Townhouse Project
Designing homes intended for sale presents a unique challenge for interior designers: creating spaces with broad appeal while still delivering a sense of personality, refinement and longevity. In this townhouse project, designer Travers and his team from F3 Studio approached the task of designing two mirror-image residences with a focus on subtle detailing, cohesive materiality and thoughtful hardware selection — including the Castella Stream handle, whose soft tubular form complements the gentle curves found throughout the interior.
Delivered in collaboration with builder and client Vital Build, architect Ikonomidis Design Studio, and RICSIA Custom Joinery, the project brings together architectural clarity and carefully resolved interior detailing.
The result is a calm, contemporary interior where gentle curves, textured materials and carefully selected hardware work together to create a space that feels both timeless and quietly distinctive.
Designing Within a Clear Framework
Travers explains that the project brief was deceptively simple.
“The initial brief was both succinct and expansive – design the interiors of two mirror-image townhouses where the architecture was already determined, and the end goal was to create houses for sale.”
While the architectural framework was fixed, the interior design needed to balance several competing priorities: broad market appeal, budget considerations and ongoing input from the builder and sales agent.
“This made the design process easier and harder in equal measure. We had to carefully manage creating interiors with vast market appeal, within budget and based on feedback from the builder and future sales agent.”
Working within the builder’s network of approved suppliers also shaped many of the decisions, though Travers and his team introduced select partners whose products aligned with the project’s design intent.
“We also worked with several of the builder’s approved suppliers, while adding our own unique purveyors to the mix – including Castella.”
The Power of Subtle Texture
At first glance, the interiors appear calm and neutral. But one of the most important design moves is a detail that many visitors may never consciously notice.
“One hidden detail in the design – that is maddeningly imperceptible in photography – is the texture of the laminate used throughout.”
Rather than relying on flat, plain surfaces, the designers specified a structured woodgrain laminate. This subtle texture provides visual depth and quietly connects the interior spaces with the surrounding environment.
“The grain effect created a beautiful visual connection to the external woodland environment, without overwhelming the achromatic interior scheme.”
As Travers notes, these subtle decisions often play a significant role in shaping the atmosphere of a space, even if they are not immediately obvious.
Considering Hardware From the Beginning
While hardware is often treated as a finishing detail, Travers explains that the team integrated these elements into the design process from the outset.
“We considered smaller elements like cabinet handles early in the design process, ensuring they were clearly modelled into the design for presentation from inception.”
The interior architecture features a series of soft curves, from joinery edges through to the stair and balustrade design. Selecting hardware that echoed these shapes became an important part of maintaining visual continuity.
“We knew with the curves present throughout the interior design, that the hardware needed to be equal — soft and timeless.”
To achieve this balance, the project features the Castella Stream Handle. With its smooth tubular form and refined stainless steel construction, the handle complements the gentle curves seen throughout the project while offering durability suited to high-use areas such as kitchens and joinery.
Designing for Broad Market Appeal
Unlike client-led residential projects, designing homes intended for sale brings a different dynamic to the process.
“As a design-to-sell project, the creative constraints felt less obvious versus a standard client lead project,” Travers reflects.
With no single homeowner driving emotional decisions, the focus shifted toward ensuring the finished homes would appeal to a wide range of future buyers.
“The reduced emotional attachment from the builder client made the process equally easier and harder, as no singular force was driving the project – apart from perhaps the ‘saleability’ of the final product.”
Because the budget and spatial parameters were clearly defined from the outset, the design team could confidently select materials and suppliers that aligned with both aesthetic and practical considerations.
“The spaces and budget were unambiguous prior to project commencement, so we had a clear direction of how much to design and which suppliers to use – Castella being our go-to for cabinet hardware that we knew would fit the allowances made.”
Designing for Longevity
For Travers, creating interiors that stand the test of time begins with restraint.
“We approach design for longevity by creating neutral material palettes, allowing updating of interiors over time through furniture and styling.”
Neutral palettes provide flexibility, but that doesn’t mean the spaces lack character. Instead, visual interest is introduced through texture, tile layouts and subtle detailing.
“While the palettes might be neutral, we often play with textures and tile lay-patterns to create visual interest – much to the dismay of our tilers!” Travers adds.
In this context, joinery hardware plays an important supporting role in shaping the overall feel of the interior.
“Smaller details like joinery hardware can play an important part in the timelessness of an interior – either by adding ephemeral character through engaging shapes, natural stones and metals – or using enduring silhouettes that respect and recede.”
The Castella Stream handle reflects this philosophy, offering a form that feels both contemporary and enduring.
A Stair Detail That Defines the Space
Looking back on the project, one particular design feature stands out as a favourite.
“We’re probably most proud of the balustrade on the stair to the first floor,” Travers says.
Rather than opting for a more economical glass or timber solution, the team developed a curved white metal balustrade that visually connects with the joinery and hardware used throughout the home.
“The design felt like it grew organically out of the other interior details; the white metal softened by curves; striking a beautiful accord with the Stream cabinet handles used throughout.”
The result is a sculptural architectural moment that reinforces the project’s broader design language.
A Designer’s Eye for Hidden Details
When asked about favourite overlooked design features, Travers’s answer reflects the playful side of good design.
“As a small design studio whose Health and Wellbeing Officer is a ginger cat [Harry], we love designs that champion functional spaces for cats without making them overt.”
From hidden passageways to elevated pathways along picture rails and shelving, the team appreciates interiors that quietly integrate thoughtful details.
“Secret doors between rooms, often in the shape of cats. Picture rail and corbel shelves as paths of overhead travel. Integrated pet stations with separate spaces for food, shelter and litter.”
A Cohesive Interior Built on Detail
This townhouse project demonstrates how thoughtful interior architecture and carefully considered hardware can work together to create spaces that feel cohesive, calm and enduring. From textured laminates to sculptural balustrades and the refined presence of the Castella Stream Handle, the project highlights how even the smallest details can quietly elevate the overall design experience.
