The quarter's concept was created by the renowned Danish architecture firm Cobe, based on the detailed plan prepared by architect Andres Alver. The construction partner for the first phase is Merko. Construction of the Greenhouse, the future quarter's landmark, began last year and will become a business and innovation center designed by Cobe and KOKO architects. Construction has also begun on the former repair workshop and the future Põhja-Tallinn's most unique event venue, which is being renovated according to KOKO architects' vision. Three first apartment buildings of Krulli are being built along Volta Street with a total of 23 apartments, designed by HG Architecture. Additionally, a serviced apartment hotel is being built in the first phase under molumba architects and the Stone Building, a commercial and apartment building designed by Pluss Architects in the heart of the quarter.

The quarter's first phase covers 34,200 m² (above-ground gross floor area), of which apartments account for 5,750 m². The landscape architecture concept for Krulli Quarter was also developed by Cobe architecture firm. The landscape architecture solution for the first construction phase is being implemented by KINO and Väli landscape architects. The Krulli development area is 10 hectares in size and includes over 100,000 m² of above-ground building volume. Over ten years, nearly 20 buildings will rise in the quarter, with over 600 homes and 3,000 workplaces being created.
