Our response to your interior brief for 58 covers on the ground floor of Kajhuset, Norra Djurgårdsstaden. *The Kvarts dining room, smoked oak counter against an iron red plaster wall* *Studio Aho Brenning Interiör* ## The premise A tasting menu lasts three hours. The room has to earn every minute. ## The brief ### A room built around one counter *The brief, as we heard it* You left a starred kitchen to cook for 58 people a night on your own terms, and you want a room that serves the menu rather than competing with it. Most tasting rooms of the last decade were designed as theatres for the pass, dark and reverent, and guests learned to whisper in them. You told us you want the opposite: nine seats at a smoked oak counter, the rest close enough to hear the kitchen, and a room loud enough that people talk. The building is new mass timber, the ceiling is bare CLT, and the opening is February 2028. If we have any of this wrong, tell us before you read on. ## The room in numbers ### The room in four numbers Figures from your floor plan and our site visit to Kajhuset on 6 April 2027. The noise target is the one we would design to and measure at the first trial service. ### Covers, nine at counter **58** ### Front of house **412 m²** ### Target, full room **52 dB** ### Longest lead time **14 wk** ## Sound and budget ### What the timber does to sound, and where the money goes Reverberation from our acoustic model of the bare room, built from the structural engineer's CLT drawings. The FF&E split is our first estimate in thousands of kronor, exkl. moms. ### Reverberation time, bare room, seconds | Label | Value | | --- | --- | | 125 | 1.9 | | 250 | 1.7 | | 500 | 1.5 | | 1000 | 1.4 | | 2000 | 1.3 | | 4000 | 1.1 | ### FF&E budget by category, SEK thousands | Label | Value | | --- | --- | | Seating and banquettes | 1940 | | Counter and tables | 1310 | | Lighting | 1120 | | Acoustic linings | 860 | | Textiles | 540 | | Contingency | 577 | ## Concept routes ### Route one, Kärnved. Our recommendation *Route one, smoked oak slatted room with red plaster wall* ### Route two, Björkljus *Route two, pale birch dining room in winter daylight* ### Route three, Glöd *Route three, iron red plaster room with steel counter* ## Materials ### Six materials for Kärnved All six are in the sample box we will bring on 3 May. Each is low-VOC, and the oak and birch are FSC certified from Swedish and Finnish mills. *Smoked oak against birch plywood* *Iron red lime plaster* *Oak slats over wool felt* *Honed limestone meeting smoked oak* *Blackened steel and grey wool* *Birch CLT ceiling panel* ## Route to opening ### Working back from the lead times Upholstery and joinery, not design, set the date. Every long-lead order has to be placed by Friday 3 September 2027, which is why the first three stages are as tight as they are. ### 1. Concept, 3 May to 4 June Route one developed in a VR walkthrough of the room, tested against a second route. You sit at the counter in the headset before anything is drawn in detail. ### 2. Developed design, to 23 July Plans, RCP, joinery details and the acoustic layout, coordinated with the kitchen designer. We work through July; most suppliers do not, so samples are booked in June. ### 3. Specification, to 3 September Every item on the live FF&E tracker you can open on your phone. You approve each order there, and deposits are released only after your sign-off. ### 4. Lead times, to 17 December Upholstered banquettes 14 weeks, counter joinery 11, pendants 12, limestone 7. We visit the joinery workshop at week six to check the first counter section. ### 5. Installation, 10 to 21 January Two weeks on site after the kitchen fit-out signs off, then a snag list closed within five working days. ### 6. Styling and trial services From 24 January to 4 February we tune lighting scenes and measure noise at three full trial services, ahead of opening on Thursday 10 February 2028. ## Clients ### From the rooms we have opened Studio Aho Brenning Interiör, founded 2018, eight people on Södermalm. Liisa Aho and Johan Brenning lead every project from the first sketch to the last trial service. > They measured the noise at our first trial service, found the bar end was four decibels over, and had extra felt behind the slats within a week. Guests now tell us they can hear each other. — Hedda Strömqvist, Restaurant Manager, Vinbaren Skiffer > Our banquettes were on a 16 week lead time and we had 15. Liisa caught it at specification, split the order between two workshops, and we opened on the date we had announced. — Saga Lundmark, Chef and owner, Matsal Vreta > I approved every order from my phone, standing in the kitchen. I never once had to ask where a chair was. — Oskar Wennerholm, Founder, Hotell Ekholmen ## Next step ### The fee, and what it is not Concept fee SEK 412,750. Later-stage fee SEK 1,284,900, covering developed design, specification, procurement management, installation and styling. Both exkl. moms at 25 percent. The FF&E budget of SEK 6,347,000, including 10 percent contingency, is paid by Kvarts directly to suppliers at trade price, with no markup from us. This response holds until Friday 30 April 2027. ### Prepared by **Liisa Aho** Founder, Studio Aho Brenning Interiör Tjärhovsgatan 21 116 21 Stockholm liisa@ahobrenning.se ### For approval by **Elias Nordahl** Chef and owner, Kvarts Johan Brenning and I can walk Kajhuset with you on Thursday 22 April if you would rather talk it through first. ### Appoint us for the concept stage By signing, you appoint Studio Aho Brenning Interiör for the concept stage at SEK 412,750 exkl. moms, from Monday 3 May to Friday 4 June 2027.
