We consider de Sitter vacua realised in concrete type IIB Calabi-Yaucompactifications with an anti D3-brane at the tip of a warped throat ofKlebanov-Strassler type. The K\"ahler moduli are stabilised together with thecomplex structure modulus of the warped throat. The volume is exponentiallylarge as in the large volume scenario (LVS). We analyse the conditions on theparameters of the EFT such that they are in the region of validity of ourapproximations, there are no runaway problems and the vacua satisfy allconsistency constraints, such as tadpole cancellation. We illustrate ourresults with an explicit Calabi-Yau orientifold with two K\"ahler moduli andone antibrane on top of an O3-plane in a warped throat, that has the goldstinoas its only massless state. The moduli are stabilised with $g_s\sim 0.2$ andvolume $\mathcal{V}\sim 10^4$ in string units, justifying the approximationused to derive the corresponding EFT. Although the model lacks chiral matter,it is presented as a proof of concept, chosen to be the simplest realisation ofantibrane uplift.
