Plan circular demolition in Roskilde

Plan circular demolition in Roskilde In Roskilde, you can see how circular demolition was planned at Musicon, the old concrete works the city bought in 2003. A pre-demolition audit of Hall 12 listed what could be used again before the selective take-down began. What you can do in Roskilde - Walk the Musicon district and see old factory ground turned into a neighbourhood (CityLoops on circular demolition) - Ask the city to require a material audit before the next public building comes down - Read the two CityLoops guides: one for the audit, one for selective demolition - If you own a building, use the Copenhagen Værdibyg guide to set a reuse aim before you tender the job (Værdibyg circular demolition booklet) - Ask designers to look at the audit while they draw the next building How to join Musicon is a public district of about 200,000 square metres, a former concrete factory and gravel pit. The city did not lock it to one fixed plan. Projects grow step by step with residents, builders, and the municipality. Hall 12 was audited by Golder: a desk study, then a field study, then a list of how to handle each material, including a store of saved parts. You can walk the district. You cannot join the Hall 12 works as a volunteer day. The audit is the pattern to copy. Why it matters in Roskilde An early list stops good doors, timber, and steel from being treated as rubbish. CityLoops found that contractors do not add this audit on their own after the contract is signed, so the city has to ask for it in the tender. A Danish client can follow the same idea with the Værdibyg steps: set an aim, survey resources, and write the handling rules into the tender. Find more community projects in Roskilde. Good to know - What is a pre-demolition audit? It is a list of materials, how much there is, how clean they are, and whether they can be used again, recycled, or must be treated as harmful. CityLoops says reuse is hard to promote without that list. - When should the first clear-out happen? As soon as the last user has left, before damp and vandalism spoil loose items.

Walk Musicon after circular demolition there

Walk Musicon after circular demolition there Musicon in Roskilde is the district where circular demolition of factory Hall 12 was planned with a full material audit. You can walk the old concrete-works ground and see a neighbourhood built from that site. What you can do in Musicon - Walk the public streets and yards of Musicon (CityLoops circular demolition) - Notice which old sheds and open ground remain beside newer buildings - Ask Roskilde to attach a pre-demolition audit to the next demolition tender - If you pay for a job, copy the Værdibyg steps: survey, set a reuse aim, then tender How to join The Hall 12 audit was done by Golder for the city: desk study, field study, and a plan for each pile, plus a store of saved parts. That work is finished. The district is still there to visit. There is no ticket and no volunteer shift for the old demolition. Come as a walker. When & where Musicon, Roskilde, Denmark. Go to the district, not to a marked door for Hall 12. The city bought the 200,000 square metre concrete factory and gravel pit in 2003. Recurring: the streets are public. Check the city pages if you want a guided note. Why it matters in Musicon The audit happened early so designers and the demolition contract could use the same list. CityLoops says that once a contractor is hired, they will not add this screening unless the tender already required it. Walking the district shows why that timing matters: the old works are becoming streets, homes, and culture space. Good to know - Can I see Hall 12 itself? Hall 12 was partly taken down after a material list. It is not a museum room. Visit the district. - What should a tender say? Require the audit and the selective take-down before the contract is signed. Source & repost Shared here so you can get inspired or find action already happening near you.

Repair & ReuseHøje-Taastrup

Use circular demolition rules in Taastrup

Use circular demolition rules in Taastrup In Taastrup, circular demolition rules were written so the old city hall would not be smashed by default. The 1980 hall at Bygaden 2 is being kept and turned into homes. That saves more than sorting rubble. What you can do in Taastrup - Walk by Bygaden 2 and see the hall that stayed up (Høje-Taastrup on the old hall) - Ask your council to require a resource map before it sells a building for demolition - Ask for at least 80 percent by weight of clean materials to be reused, recycled, or recovered if a part must come off - Look at the new city hall, which was built with a recycled concrete foundation (CityLoops handbook) - If you pay for a demolition in Denmark, set a reuse aim with the Værdibyg guide before the tender (Værdibyg booklet) How to join The municipality sold the old hall to IKANO with circular conditions. A pre-demolition audit had to map harmful materials and parts worth keeping. Selective demolition applied to parts that could not be used in place. The later plan keeps the hall, about 17,000 square metres, and turns it into about 200 homes, with about 130 townhouses around it. The old heat plant on the grounds is planned as a neighbourhood house of about 200 square metres. The grounds are about 100,000 square metres. Staff left in February 2023 for a new hall at Rådhusstræde 1. This is not an open-house tour. You can see the building from the street. Why it matters in Taastrup Keeping the hall avoids about 20,000 tonnes of new raw material and about 2,000 tonnes of carbon dioxide compared with knocking it down, according to the CityLoops account. A resident in Copenhagen can reach Høje-Taastrup by suburban rail and see a real case of "do not demolish if the building can still work". Find more community projects in Høje-Taastrup. Good to know - What if some parts still come off? The updated rules still ask for selective demolition of those parts, and they count a structure that stays standing as fully kept in use. - Where is the new hall? It is at Rådhusstræde 1. The photo shows that tower. The old hall is at Bygaden 2.

See the kept hall: circular demolition Taastrup

See the kept hall: circular demolition Taastrup The old Høje-Taastrup city hall at Bygaden 2 is the place where circular demolition rules changed the plan from a full knock-down to keeping the building. You can see it from the street. What you can do in Taastrup - Walk to Bygaden 2 and look at the 1980 hall from public ground (municipal note) - Compare it with the new hall at Rådhusstræde 1, built with a recycled concrete foundation - Ask a council you vote in to sell its next empty building with a reuse rule, not a default demolition - Read the CityLoops lesson: name the need (homes, workplaces) before you name a demolition How to join There is no public tour in the source. The building stood empty after February 2023, when staff moved to the new hall. IKANO is turning the old hall into homes and adding townhouses on the grounds. A small neighbourhood house is planned in the former heat plant. Stay outside unless the owner publishes a visit. When & where Bygaden 2, 2630 Taastrup, Denmark, by Høje Taastrup village. The new hall is a different building at Rådhusstræde 1. Recurring: the old hall remains a street address you can look at. Works may change access, so check the municipal page. Why it matters in Taastrup The CityLoops account says keeping this hall saves about 20,000 tonnes of raw material and about 2,000 tonnes of carbon dioxide versus demolition. The sale still carried a rule: if parts must come off, at least 80 percent by weight of the clean material should be reused, recycled, or recovered. A structure that stays up counts as kept. Good to know - Is the hall still there? Yes. The later municipal note says it will be transformed, not razed. About 200 homes are planned in the hall, plus about 130 townhouses. - Can I go inside?
