You will find that as time passes, the building naturally dries out and sometimes building materials shrink, which may cause small cracks to appear in your home. This is not a defect unless the cracks are substantial (wider than a £1 coin). To keep cracks and gaps to a minimum, you need to allow all the materials used in constructing your home to dry out gradually.
