My commitment to you

Deciding to build a new house, extend or refurbish is a major decision that can be expensive and daunting. You will encounter a minefield of planning policies, building regulations, cost implications and design issues on even the smallest of projects. All of these will determine what you can do and how you go about doing it. I do understand the value and significance of your investment and will be committed to finding you the best approach to suit your needs by balancing good design and within budget.

To see examples of my current and previous projects please visit my BLOG. I'm here to help you, as a Chartered Member of CIAT I will guarantee you good design, a professional and friendly service and will work closely with you to obtain your goals within your budget. 

Passion for Architecture

I’m passionate about good architecture, too many times we all see buildings which are unsightly and have not provided the client with a good return for the money invested. Whether you are building a new house, extending or altering your existing home there are three fundamental principles which I can help you achieve.


1. Function:  How the space will be used. An extension or new dwelling must accommodate practical requirements for whatever purpose you need it to serve.


2. Structure:  How your building will stand up. Whether it includes steel beams or brick walls, the structure must resist gravity and the loads placed upon it. 


3. Beauty:  This refers to the visual and sensory appeal of your building. Beauty is the ultimate test of good architecture. Without beauty, your functional space will merely be utilitarian and not architecture. Good architecture can use the same materials as existing buildings but tweak them in new ways. Other designs can introduce a completely different style. 


Will your new house / extension surprise, inspire, delight, or disturb? A tranquil courtyard filled with plants and fountains soothes our senses, while a dark, underground passageway may fill us with dread. Good architecture is about the science of structures, the craft of building, and the art of space-making and the rewards for us all can be fantastic.
