Studio Bosko / Zander Rooftop
01 / The material brief
Zander Rooftop is a layered Berlin attic interior by Studio Bosko. The photographs show a project built from contrasts: pale architectural volumes, dark wood-like joinery, warm herringbone, glossy bathroom fields, expressive vanity surfaces and bright red furniture moments.
Our job was to support that freedom with a disciplined surface package. We did not treat “use the same slab everywhere” as coordination. We separated horizontal from vertical applications, dry areas from wet areas, fixed wall panels from moving cabinet fronts, and full-slab supply from pieces that needed factory fabrication.
That distinction protected the design. It let a quiet floor remain quiet, a dark feature wall keep its direction, and a small vanity become expressive—while the people pricing, cutting, packing and installing the work could see exactly what they were responsible for.
The dark architectural spine had to align across wall planes, shelves and furniture-scale details while the surrounding surfaces stayed deliberately calm.
02 / One palette, four surface jobs
From a distance, the project reads as one confident composition. Up close, every application changes the technical brief. We organised the scope by what the surface had to do, how it would be fabricated and who had to approve the supporting system.
The open kitchen sits in the centre of the roof volume, so the dark work surface, cabinet faces and red island had to read as one composition from the dining table, stair and living area. We treated sink and appliance openings, worktop joints, exposed edges, door clearances and grain direction as finished-design decisions rather than workshop details to solve later.
Confirm: appliance models / sink method / finished edge / face direction / local supportThe interior moves between warm herringbone, quiet light fields, dark tiled rooms and strong joinery. At every threshold we needed the finished levels, substrate, movement strategy, perimeter cuts and cleaning expectation—not only a colour reference. Large-format pieces can reduce visual interruption, but joint location and access still have to be designed.
Confirm: substrate / finished level / joint map / slip need / perimeter and doorway cutsThe two bathrooms use very different palettes, yet both demanded the same discipline. Basin openings, tap centres, wall returns, exposed faces, splash zones and access for plumbing had to be coordinated before fabrication. Material selection supported the visual brief; waterproofing, falls and the complete installation system remained with the qualified local team.
Confirm: basin template / tap drilling / wall return / waterproofing interface / installer toleranceFor the dark living-room spine, shelving, tables and fitted pieces, the surface had to work at furniture scale. We looked at the face that would be seen, how corners met, whether the pattern should run vertically or horizontally, where handles and hinges landed, and how the panel was supported. A furniture skin cannot be quoted as an anonymous square metre.
Confirm: carcass / panel thickness / corner build-up / hardware / face sequence / handling
03 / Wet-area coordination
The dark bathroom uses a compact mineral top over warm fluted joinery. The green bathroom pushes the focal surface further, wrapping a basin opening with an expressive red-brown stone direction. They look spontaneous, but both depend on precise coordination.
Before fabrication, we needed the actual basin and tap information, finished cabinet dimensions, visible edge map and access strategy. Before installation, the local team still had to confirm waterproofing, backing, falls, joints, sealant, adhesives and tolerances.
Project note / Funtek perspective
We protect an expressive interior by making the invisible decisions visible: which face shows, which way the grain runs, where the joint stops, what the installer receives and what remains the local contractor’s responsibility.
04 / From image to ordered surface
A photograph can establish mood, but it cannot release material. Our sequence moved from room intent to physical sample, then to finished-piece information and finally to identified delivery packages.
For every room, we recorded whether the material was a floor, wall, worktop, vanity, door front, shelf or loose furniture component. We noted wet exposure, heat, sunlight, cleaning, traffic, visible edges and the local fixing or support concept. This stopped one attractive colour from becoming one careless specification.
Current physical samples were reviewed beside paint, timber, metal, lighting and textiles—not on a phone screen. Directional wood and stone patterns received a clear top, bottom and face direction. Where variation or batch allocation mattered, it was attached to a zone rather than left as a general note.
Finished-piece drawings identified dimensions, orientation, openings, corner build-ups, exposed edges, hardware conflicts and tolerances. For a vanity, we needed the basin template and tap centres. For cabinet fronts, we needed the carcass, hinge and handle logic. For floors, we needed joints, transitions and perimeter cuts.
Only approved information moved to cutting. Piece IDs connected the drawing to the packing list, while crates or packages followed the room and installation sequence. The receiving team could inspect labels and condition before distributing pieces, and the installer retained responsibility for checking the site before fixing.
05 / Shop the material direction
We matched the project visually and by likely application: a deep wood direction, a light oak route, a quiet micro-cement field and an expressive focal stone. Open the cards to compare the products, then request current samples for the exact room.

Product recommendations are visual and application-led matches, not a substitute for an approved physical sample or complete technical specification. Confirm current product code, finish, thickness, available size, batch appearance, fabrication method and local installation system before ordering.
06 / A quote the project team can compare
A rooftop interior combines flat areas with many small, high-effort pieces. The square metres may look modest while the number of finished edges, sink openings, mitred returns, cabinet fronts and room packages drives fabrication and packing time.
Our quotation therefore separates material, fabrication, packaging and freight assumptions. It states whether the scope is full slabs or finished pieces, what drawings are included, which information is provisional and what work stays with the local fabricator or installer.
07 / Before your own rooftop project
Not automatically. A supported wall skin, a floor module, a vanity top and a cabinet door have different spans, loads, edges, openings, handling risks and fixing systems. We review each application with the fabricator or installer, then confirm the available product thickness and finished build-up. The responsible local team must approve the substrate, support, fixing and complete installation system.
Send finished piece sizes, the carcass or backing material, visible faces, edge and corner treatment, handle or hinge locations, preferred grain direction, quantity, tolerance and whether pieces will be fabricated at the factory or locally. A door front with concealed hardware and a fixed wall panel may share a colour, but they should not share an undefined quotation line.
No. The sintered stone is the finish material, not the complete wet-area system. Waterproofing, falls, drains, penetrations, flexible joints, substrate preparation, compatible adhesives and local code compliance remain part of the qualified designer and installer’s scope. We coordinate slab sizes, openings, edges and material data around that approved system.
The cards show the Funtek product routes that best match the visible design language and intended applications. Photography, screens, lighting and current production can change how a surface appears. Before ordering, request current physical samples and confirm the product code, finish, thickness, batch appearance, face direction and intended use against the project drawings.
Start with the difficult detail
Send the latest plan, elevation, application list and three difficult details. We will help separate material choice, fabrication scope, packing and local installation responsibilities before the quotation becomes expensive to change.
