Berlin Rental Market Dashboard

An interactive dashboard analysing Berlin's rental market by district, price, and trend — my capstone for Le Wagon's Data Analytics bootcamp.

📊 Explore the live dashboard

Berlin Rental Market Analysis — overview: 12 districts, 82 neighborhoods, 30K listings

Pipeline

  1. Extract — real-world Berlin rental listing data loaded into BigQuery
  2. Transform — cleaning and modelling with advanced SQL, organised into layered BigQuery datasets following the raw → intermediate → marts pattern, so each transformation step is isolated and reusable
  3. Visualise — interactive exploration in Data Studio: filter by district, price band, and time period

Tech stack

  • BigQuery — data warehouse with layered datasets (raw / intermediate / marts)
  • SQL — extraction, cleaning, aggregation
  • Data Studio (Looker Studio) — interactive dashboard

What the dashboard shows

Transit & Centrality — rent distribution across Berlin
Transit & Centrality
Centrality drives rent more than transit proximity.
Premium neighborhoods vs. rent — amenities and price gap over time
Premium Living
The high/low gap has grown 51% since 2020.
Bigger Space for Better Value — apartment size vs. rent per m²
Best Value
Biesdorf, Hellersdorf and Marzahn lead on value score.

What I'd explore next

  • Trend forecasting per district
  • Joining in open data on transport access and amenities to explain price variation
