🎉 Official launch day of our Optoppen knowledge hub and viability tool! 🎉 Today we brought together developers, city officials, architects, engineers and academics from across Europe to showcase the new web ‘platform’ and tool. The culmination of a year-long project, we’ve been compiling research and innovation in vertical extension with biobased materials; developed a library highlighting relevant policy developments across Europe, and a bank of case studies showing how Optoppen can be done. The website is also where you’ll find our building viability tool, which allows asset owners and developers to easily test for Optoppen potential, understanding how much new floorspace can be created and how much carbon can be locked away. We are so grateful to all of our collaborators across cities, industry and finance – and to our funder, Built by Nature.

Optoppen: building up with timber
Real Estate
Densifying our cities vertically with low carbon materials
About us
*Launched in November 2024: A new platform and tool for building owners, investors and cities - easily analysing the potential for building up with timber* From 2020 to 2060, the world is expected to add 241 billion m2 of new floor area to the global building stock — equal to a Paris to the world every week for 40 years.* We need to provide the additional built space we need using methods and materials that respect our carbon boundaries. Enter ‘Optoppen’ – the Dutch term for building on top of existing structures – a practical solution that avoids carbon-intensive demolition and rebuilding. Adding timber extensions to the tops of buildings increases floorspace in a way that minimises construction emission, using the structural capacity they have to spare. Throughout 2024, European network Built by Nature funded a consortium of diverse partners led by Whitby Wood and including Mule Studio, New Urban Networks EU, Holland Houtland, Institute for Advanced Architecture of Catalonia, Creative City Solutions, and Rising Tide, to develop an open-source knowledge and technical information platform to increase our understanding of vertical extension using mass timber. www.optoppen.org *UN Environment programme, March 2024

Strategisch Omgevingsmanager Gebiedsontwikkeling & Industriële Woningbouw en Bouwstroom: ik luister, kietel, verbind en ga uit van #hetkanwel
Soms kom je iets bijzonders tegen of word je voor iets unieks gevraagd. Met dank aan de verbinding door Léon van Geest kwam Lutz Harbaum -zonder linkedin- bij ons programmateam Optoppen Provincie Zuid-Holland op de lijn. Of we wilden meewerken aan een nieuwsitem voor RTL Aktuell Duitsland? Natuurlijk doen we dat graag!! De toekomst van bouwen in Zuid-Holland is modulair en industrieel en waarom niet het dak als bouwoppervlak te benutten: OPTOPPEN! En voor dit nieuwsitem is Rotterdam als "optopdecor" gekozen 🌟 En terecht, wat heeft de stad -overigens 26 jaar geleden mijn eerste werkgebied vanuit Wonen- veel bijzondere Optop-voorbeelden te bieden. Optoppen is méér dan alleen woningen op een dak 🏗️ , het is ook duurzaam, innovatief, draagt bij een leefbaarheid en ruimte-efficiënt: optoppen biedt dé oplossing voor stedelijke groei zonder extra grondbeslag. En wat leuk dat we dit hebben kunnen vertellen aan onze oosterburen :-) 🎥 Een kleine 10 dagen geleden mocht ik "schitteren" in een item van RTL Aktuell Duitsland samen met Yvonne Rijpers Chantal Zeegers en is een schitterende optopper gefilmd aan het Oostplein van LG architecten Van Nederlands het provincieverhaal vertalen in het Engels en dan in het Duits nagesynchroniseerd worden is ook een ervaring op zich 💡 Dank voor de gastvrijheid, verhalen en preview rondleiding op het dak van de Klapwiek, de eerste Optoppers Nieuwe Stijl, Remco Bouter Rina de Groot-De Bue Tim Peeters André Hehemann Lisette V., alle collega's op de bouwplaats voor begeleiding en vooral collega Sthijn van Kampen voor alle coördinatie en regelwerk! Het item is echt gaaf geworden en wat zijn de beelden van Rotterdam te gek!! #Innovatie #Optoppen #rotterdamsedakendagen #betaalbaarbouwen #Rotterdam #RTLAktuellDuitsland #trots #hetkanwel #eenthuisvooriedereen

Optoppen: building up with timber reposted this
Hey! Haven't you always wished there was a free web app that could tell you how many floors you can add to your existing building? Well lucky you, your wait is over! After only 2 minutes of using the app, I have ascertained that if I owned a 12 storey concrete framed building (in my dreams!) on solid ground, I could probably knock two of those floors off the top, and add 9 floors of timber - YES 9 FLOORS! - which would provide me 70,000m2 of extra space (a nice big bedroom for me and my cat 😻 ) and store 26,000 tonnes of CO2 in the structure 🌲 (that's more CO2 than me and my cat would emit if we lived for 2000 years!). ⁉️ "So what?", I hear you say..... and in anticipation of this question, I wrote about exactly why this is so good for cities 🏙️ and the planet 🌍 here in the Architects’ Journal: https://lnkd.in/ebkKxHkj And if you want to know how big your cats bedroom could be (or even better, how many social homes you could create) go have a play at www.optoppen.org

Optoppen: building up with timber reposted this
📐 Tomorrow, a new, free online tool for #building owners, #developers and #cityplanners to understand their opportunities for vertical extensions is going live – 'Optoppen: building up with timber’. 🌎 From 2020 to 2060, the world is expected to add 241 billion square metres of new floor area to the global building stock – equal to a Paris – every week for 40 years. To reduce carbon emissions in time, we need to urgently adopt new methods and materials that respect our carbon boundaries. 🏗️ #Optoppen explores vertical development with bio-based materials, using existing buildings and their structural capacity to create new homes and workspaces – efficiently, fast, and carbon-saving. 💡It takes on many of the questions central to our built environment over the next decade, considering how we can deliver new space at 2040+ embodied carbon targets, use our cities’ existing infrastructure, unlock asset value to pay for retrofitting, and use low-carbon, smart construction methods to create high-quality spaces. 📈 This new, dynamic 'Optoppen' tool, built by Mule Studio and based on Whitby Wood’s structural calculations, allows users to easily and quickly assess which buildings can be extended, and by how much. ✨ If you are interested in learning more, we highly recommend you attend the webinar on Thursday, 28 Nov 2024, 12:30 - 13:30 GMT to talk with the team behind the tool yourself. You can register via EventBrite below. https://lnkd.in/ecyP4Mcw Speakers include: Joe Penn, Sustainability Officer, City of London Corporation Alexandra Jansen, City of Amsterdam Daniel Ibañez, CEO, Institute for Advanced Architecture of Catalonia Kelly Harrison, Director, Whitby Wood Harri Lewis, Director, Mule Studio Frederic Schwass, Chief Development Officer, General Projects Thijs Müller, Co-Founder, Creative City Solutions 🔧 This new tool was developed via a Built by Nature Fund to create an open-source knowledge and technical information platform to raise awareness and understanding of how vertical extension of our buildings and cities using mass timber can unlock much-needed floor area, create new carbon stores, and keep construction emissions to a minimum. 🌐 Learn more about the tool by attending the webinar tomorrow, or by following Optoppen: building up with timber for more updates.
