We present forecasts for the cosmological constraining power of ``$N\\times2\\mathrm{pt}$'' analyses -- which combine galaxy clustering, galaxy weak lensing, galaxy-galaxy lensing signals and 21cm Intensity Maps. By assuming cosmology surveys from an SKA-Mid AA4, we show that such an $N\\times2\\mathrm{pt}$ analysis will be able to deliver measurements of $\\sim1\\%$ precision on $\\Lambda$CDM cosmological parameters.
