Interior design process

KOKO3:s expression
Our visual language is rooted in culture, art, and creative expression.
We look for solutions that feel fresh and offer surprising perspectives, curiosity, and joy. We are inspired by people.

Close customer collaboration
Co-development and straightforward client collaboration are seamless parts of our interior design process. We work as project leaders and push for co-development. We supervise the planning and help with sourcing. We always consider the profitability and feasibility of each project. We have a wide network of experienced partners in the construction industry.

3D design aids
We use 3D software as the base for our design work. We use models for design, client communication, unit calculations, and cost predictions. If you want to experience your space before construction, we also offer VR tours or 3D models.

Topical themes in interior design
A hybrid office is the new normal of work environments. Other current themes include shareability, safety, and sustainable building methods. The hotel and restaurant sector focus is on memorable, multi-sensory spaces.

Work and learning environment development

The digital turn and hybrid work are revolutionizing work environments. We help companies see the benefits, challenges, and development needs of their workspaces. The catalyst for development can be moving to new premises, functional and organizational changes, or space-saving.

Change isn’t always easy. We have developed processes and tools that facilitate work and learning environment development every step of the way. We look for functional solutions with the help of co-development and service design. Our social and experienced team produces workshops, info sessions, and interviews in addition to design.

A development project can consist of a business’s premises or even the concept of an entire property. In addition to the private sector, we develop cultural sector workspaces and learning environments for schools, universities, colleges, and other educational institutions. Our clients include Senate Properties, the Ministry of Foreign Affairs in Finland, the University of Helsinki, and many others.

Our services include:
Work environment concepts | Learning environment concepts | Project planning | Room schedules | Interior design | 3D-planning BIM | Co-development | Interactive workshops | User questionnaires | Work environment interviews | Info sessions | Communication support

Participatory design and co-development process

Co-Development
Our approach is based on service design and offers tools for a successful result. We look for solutions with the help of co-development, including work environment interviews, interactive workshops, functional room schedules, 3D visualizations, and open communication. Our processes cover the entire trajectory of spatial development, from needs assessment to completed spaces. We support project management and communication processes throughout the project.

Tailored processes and tools – ask us more
We have plenty of experience in the successful realization of vast and complicated development projects. We are happy to tell you more about our successes and the processes and tools that we have developed along the way. We believe all problems are made to be solved!

Topical themes
We solve issues related to hybrid work, co-working, security, and sustainable building methods. Topical themes associated with learning environments are multi-functionality and space sharing. New learning facility solutions are developed from pedagogical perspectives, with experience-based learning and the roles of both teachers and students at the forefront.

Graphic design

We deliver the message and make it noticeable and memorable.

We produce elements of visual identities, such as logos, typography, signage, infographics, illustrations, patterns, and image concepts.

We move agilely in the two-dimensional world and bring ideas to three-dimensional spaces and surfaces. The seamless alliance between spaces and graphical elements creates a coherent, individual experience that supports the brand, its values, and functions.

Our services include:
Art Direction | Visual concepts | Brand identity | Naming | Logos | Slogans | Typography | Signage design | Taping | Graphic guidelines | Visual elements | Image design | Pictograms | Layouts | Package design

The core principles of our service
We are experts in both spatial environments and surface design. The role of graphic elements in spaces can be to support, guide, or inspire. We will brighten your existing brand with strong expertise — or create you a brand new one.

Here’s how we can help
Our services cover brand identities, signage design, pattern design, graphic guidelines, marketing materials, layouts, production planning, and surveillance. We provide Art Director services, including photoshoot planning, organization, and styling.

Two-dimensional depth
We design deeply and strategically: the core of our design process is always to create a distinguishable story and bring it to life in multidimensional ways. Graphic elements play a key part in spatial environments that aim to communicate and strengthen a brand image.

Architectural design

Interior design often requires architectural plans. We provide architectural services, which facilitate communication and minimize overlap.

We often serve as the principal designer and architect in renovation and conversion projects. Successful space modifications depend on our vast knowledge of construction processes. We have plenty of experience in principal and architecture design in several historical conversion projects.

KOKO3’s architectural planning includes close collaboration with authorities, preservation entities, builders, contractors, and technical designers. As principal designers, we handle the above as well as permits related to the project.

Our services include:
Principal design | Architecture design | Property concepts | Change of use | Room schedules | Design leadership | Design coordination | Conversion planning | Renovations | Permit processes | Authority collaboration | Preservation processes | 3D design

Architecture design process

Architect and principal design
Architect and principal design services support our interior design. As principal designers, we lead the design team and are responsible for coordinating plans and permits.

3D design aids
We use 3D software as the base for our design work. We use models for design, client communication, unit calculations, and cost predictions. If you want to experience your space before construction, we also offer VR (Virtual Reality) tours or 3D models.

Our partners
We have a wide network of experienced partners in the construction industry, including builder consultants, technical designers, and contractors.

Product design

Unique elements, such as light fixtures, details, and furniture complete an extraordinary space. Fixed furniture and custom pieces create added value in interior design projects. They create customized solutions that make a space special, perfectly reflecting needs and requirements.

We design customized furnishings for restaurants, hotel rooms, conference rooms, and any other space that requires functional support and a strengthened identity.

We create custom-made furniture for nearly all projects and find the most appropriate makers for them. We also design consumer products, such as the Lempi furniture collection for Matri by Fennobed.

Our services include:
Product design | Fixed furniture design | Custom furniture design | Limited series and consumer products

Product and Furniture Design Process

Stand out with custom furnishing
Reception desks, banquette seating, auditorium furniture, display shelves, and hotel room furniture are examples of custom and fixed furniture. We produce detailed production plans for custom furniture and consider practicality, budget, and production requirements

We find the makers
Our vast network of makers includes carpenters, woodworkers, production engineers, blacksmiths, upholsterers, glassblowers, restorers, and artisans. It ensures that we can offer clients customized solutions at competitive prices.

One of a kind
Our custom furniture designs are always specifically designed and tailored for a specific project — our designs are one-of-a-kind
