We introduce the generalized Besov-type space $ B_{p\theta}^{\varphi}([0,1];H) $ over the Haar basis. We give the two-sided estimate for the norm of functions of the space in terms of their Fourier–Haar coefficients. Also, we establish a criterion for the embedding $ B_{p\theta}^{\varphi}([0,1];H)\hookrightarrow L_{q\tau}[0,1] $ and some two-sided estimate for the approximation of $ B^{\varphi}_{p\theta}([0,1],H) $ in the metric of $ L_{q\tau}[0,1] $ , with $ 1\leq p<q<+\infty $ and $ {1\leq\tau<+\infty} $ .
