Architect Paul Lamb designed this Westlake, Texas retreat with the great twentieth-century British architect Edwin Lutyens, in mind. Lutyens was best known for his imaginative adaptations of traditional style, and both Lamb and interior design firm Fern Santini have followed suit here. This limestone residence is cozy in front, but opens to the lake with mullioned floor-to-ceiling windows. Oushak rugs, a subtle palette, and comfortable sofas aren’t so serious when paired with quirky occasional chairs. Glamour is serious, though, in the master suite where luxe is a pleasure to behold.
