Modern Luxury Interior Design in Singapore

Summerhaus D'zign is a bespoke interior design company in Singapore, creating high-end interiors for landed homes and condominiums. Founded in 2012 by Jess Koh and Larry Lim, our studio is an interior design firm that specialises solely in landed homes and high-end condominiums across Singapore. We provide interior design services from conceptualisation to actualisation for private residential properties, with projects recognised regionally and internationally by homeowners and property developers.

Since 2012, our studio has focused on calm, modern interiors that balance quiet elegance with everyday practicality. Every bespoke interior is led by our founding partners and a seasoned team, combining clean lines, carefully planned storage, layered materials and lighting tailored to the way you live.

Our approach is led by proportion, material and light, rather than ornament. Each project is shaped around the property and the people who live in it, whether the home is a high-end condominium, terrace, semi-detached or detached house. The result is a modern interior that feels considered, comfortable and quietly distinct.

 

Recognition

Our work at Summerhaus D’zign has been recognised at the International Property Awards, the Asia Pacific Property Awards, the Tatler Design Award, the IDA Design Award and the A'Design Award. Recent wins include the Asia Pacific Property Awards 2024/2025 for Interior Design of a Private Residence, together with recognitions at the Tatler Design Awards for our landed and condominium projects. We have also been named among the Tatler Top 50 Most Influential Names in Singapore Design, and our homes have appeared in Tatler, The Peak and other lifestyle publications.

These recognitions matter to us less for the awards themselves than for what they reflect. A consistent body of work, built carefully over more than a decade.

Our Approach

We describe our approach in two words:

  • Bespoke: Because every project is shaped around the homeowner's lifestyle, habits and preferences, and no two homes we design are alike. We believe that each home should feel unique to the family living in it, not a variation of a house style. 

  • Novelty: Because design is new and no two homes we design are alike.

Our work sits within the modern luxe register: sophisticated, refined, but never showy:

  • We favour timelessness over trend, and functionality over feature. 

  • Materials are chosen for how they age rather than how they photograph on the day of handover.

  • Storage is planned so that the architecture of the home does most of the quieter work. 

For homeowners who value craftsmanship over trend, our role as a bespoke interior design firm is to listen first and design second. The brief is read carefully, the property is understood on its own terms, and the design is allowed to settle into something that feels personal rather than imposed.

As Seen In

Summerhaus D'zign has appeared in publications such as Tatler and The Peak, together with other design and lifestyle platforms that highlight notable homes and the firms behind them. These features showcase the sophisticated, high-end aesthetic defining our interior design projects in Singapore.

What Defines a Modern Luxury Home

Modern luxury, in the way we practise it, is a question of editing rather than adding. A true bespoke interior is not the home with the most features. It is the home where every feature has earned its place:

  • Storage that disappears into the architecture

  • Lighting that shifts without being noticed

  • A tight palette of stone, timber and metal chosen for how they feel and how they age

For Singapore homes in particular, bespoke interior design has to absorb the climate, the compact floor plates, and the rhythm of family life across generations. A well-designed home should feel cooler than the corridor it opens into, quieter than the street it sits on, and easier to live in than the one before it. Anything else is decoration.

This is the principle that runs through our interior design work, whether the project is a condominium or a larger detached house. The size of the home changes. The discipline does not.

Selected Projects

A selection of recent landed homes and condominium interiors. Each project is a reflection of the homeowners and the property, and of how modern luxury interior design adapts to both.

Landed Homes

Our work on modern luxury house interiors spans terraces, semi detached and detached homes across Singapore. Each landed property is approached as a renewal rather than a renovation, with layouts, materials and lighting planned around the way the family lives. The result is a bespoke design that feels generous without excess

Condominiums

Condominium interiors call for precision. Modern luxury interior design in a condo is shaped by careful planning, with full height carpentry, aligned sightlines and a tight palette of materials. The result is a high-end look that feels more spacious, more organised, and unmistakably a home rather than a unit.

Working with Summerhaus

Engaging Summerhaus means engaging the studio rather than a single designer. Projects are run as a team effort, with constant communication between our designers and the homeowners. We see designing as a two way channel. The brief is the start of the conversation, not the end of it.

We are design centric during planning, often putting our proposals through several rounds of internal revision before they reach the client, so the work shown is considered rather than first draft. Once the design direction is agreed, our team co-ordinates closely on materials and details, with as much attention paid to how a home will live in five years as to how it photographs on handover day. As part of our interior design and project management service, we manage appointed contractors directly on your behalf throughout the build, so the design intent is carried through cleanly from drawings to finish, handing over a home that looks and feels high-end.

Most of our clients come to us because they want a home that reflects them, rather than a house style applied to their address. Our role as an interior design firm is to hold the structure of the project steady so that the design conversation can take whatever shape it needs to, bespoke only to you.


Frequently Asked Questions About Bespoke Interior Design in Singapore

  • Modern luxury interior design in Singapore is less about ornament and more about clarity. Well proportioned spaces, considered materials, and lighting that shifts through the day. It is luxury that is felt rather than displayed, suited to a climate and a way of living that values calm interiors over decorative ones.

  • Budgets depend on property size and scope of work, but bespoke interior design in Singapore usually requires enough allowance for layout changes, custom carpentry and quality finishes. Condominium units may start from a lower range, while landed homes generally require higher investment due to larger floor areas and more complex works. We discuss budget ranges early and shape the proposal around what is realistic for you.

  • Yes. We work exclusively on private residential projects, including terraces, semi-detached and detached houses, as well as high-end condominiums. From compact terrace refits to detached house interior design at bungalow scale, each property type carries its own constraints, and our approach adapts to suit. The principles, however, remain consistent.

  • Summerhaus D'zign is one of the few Singapore studios that works exclusively on landed homes and high-end condominiums without splitting attention across offices, retail or hospitality. Our one- stop interior design and project management service keeps design, procurement and on site co-ordination under a single studio, which is why homeowners looking for bespoke high-end residential work often come to us.

  • Summerhaus D'zign is a boutique studio led by founders Jess Koh and Larry Lim, with an in-house team of designers, trained in interior design and selected for their eye for detail. Engaging us means engaging the studio rather than a single designer, with the founders involved across the design direction of each project.

  • Design and documentation generally take several weeks. Construction varies. Condominium builds tend to be shorter, while a landed home renewal may run several months. We agree on a realistic timeline early so the project can be planned around your move in.

  • Often, yes. Elegant condo interior design depends on disciplined planning. Integrated storage, aligned sightlines, and a restrained material palette. Smaller homes can feel more luxurious than larger ones when the planning is right.

  • For landed homes, luxury interior designers have to work with multiple levels, stronger indoor and outdoor connections, as well as account for more freedom to alter structure. For condominiums, we work within existing walls, building rules and fixed services, focusing on flow, storage and comfort. In both cases, the aim is a coherent home interior design that suits how you live.

  • Share your floor plan and a few words about how you would like to live in the home. We will follow up to arrange a conversation, either at our studio or on site. There is no obligation, and no assumption that the project will proceed until the brief and the fit feel right on both sides.

  • Yes. Our firm handles high-end interior design projects for clients who travel frequently or live abroad. We use video calls, shared online folders and regular photo updates so that you can review layouts, finishes and progress without being physically present.

  • When choosing a luxury interior designer in Singapore, it helps to look at experience of handling high-end and complex projects, a portfolio of completed projects, awards, client reviews and transparency with processes, fees and timelines. You should feel comfortable with both the design language and the way the team communicates, as you will be working closely together throughout the project.
