A personal building design service for a personalised project

With over 25 years of experience in building design, we have found that our personal and respectful building design service creates fantastic results every time.

By talking regularly with both yourself and your builder we work together to create your perfect extension design. From house extension to garage conversions and loft conversions, we are happy to take on any job in the Hampshire and Dorset area.

Our initial site visit and project discussion is completely free of charge, giving us the chance to find out your extension requirements and show you previous drawings to give you an idea of our service.

• Free initial house visit and extension design discussion
• We are a registered National Home Energy Rating Assessor
• 25 years of experience
• We can provide references on request, many from builders whom we have worked with in the past
