The Mellon family have outgrown their flat. It's time to move, but none of the houses they look at are quite right, so they decide to build their own house. Masha is an architect. She designs a house that accommodates the Mellons' needs, their budget, and most importantly the environment. It is an eco-house.

The Mellons Build a House is a hugely enjoyable picturebook that takes the reader step by step through the design and construction of a house. Heat pumps, solar panels, insulation and rainwater harvesting are all explained, and brought to life in Nik Neves's warm, inclusive illustrations.
