Blokbook is a Finnish booking service for housing companies, designed to make shared spaces easier to reserve, manage and use. Through its web service and mobile app, residents can check availability, book facilities such as saunas and laundry rooms, and pay for bookings. Housing company boards can set prices, offer one-off or recurring reservations, and track facility use and income in one place.

The platform also helps property managers and maintenance companies oversee bookings, residents and equipment across multiple housing companies. Its plans range from a free option with basic booking features to paid packages offering unlimited resident accounts, calendars for multiple spaces, online payments and reporting. The Smart package adds smart-lock integration, sauna heater controls, energy-saving automation and access-control reports.

Where compatible equipment is used, access can be managed with app-based entry or time-limited door codes, while devices can be scheduled around reservations. Blokbook aims to reduce administrative work, improve use of shared facilities and support more efficient energy consumption.
