As an architect myself I fully appreciate when I see projects that feature elegant design inside and out. A great example is the The Kerferd House by Whiting Architects ,a beautifully renovated house by architect Steven Whiting and Carole, his creative-director wife.
The details of this renovation are, I think, worthy of looking into more carefully. From the beautiful materials that adorn the walls that seem to coexist perfectly juxtaposed to the original presently exposed brick walls, to the selection of muted colors that accentuate not only the design but also the shape of the cleverly designed spaces. Do check the rest of their residential projects for more inspiration or even for ideas on minimal architectural design.
