Costello Companies has worked with VanDeWalle Architects for over 35 years on the design and development of multifamily apartment complexes throughout South Dakota, Nebraska and Wyoming. Their vision, expertise and attention to detail has fit well with our development philosophy. We are committed to developing and building energy efficient units and the VanDeWalle team has been an instrumental partner in fulfilling that vision. They were our architects on the first Energy Star Certified apartment complex; the first LEED Certified affordable apartment complex; and the only Passive design apartment complex in South Dakota. They bring a level of expertise and commitment to the developments and to our company that reaches beyond architect services. It’s a relationship and partnership we value and know we can rely on now and in the future.
