The possibility of neutral, brane-like solutions in a higher dimensional setting is discussed. In particular, we describe a supersymmetric solution in six dimensions which can be interpreted as a "three-brane" with a non-compact transverse space of finite volume. The construction can be generalized to n+4-dimensions and the result is a n+3-brane compactified on a n-1-dimensional Einstein manifold with a non-compact extra dimension. We find that there always exists a massless graviton trapped in four-dimensions while a bulk abelian gauge field gives rise to a unique four-dimensional massless photon. Moreover, all massless modes are accompanied by massive KK states and we show that it is possible in such a scenario the masses of the KK states to be at the TeV scale without hierarchically large extra dimensions.
