“Gill and Hampshire Design Consultancy were recommended for a small barn conversion near Petersfield that we recently completed. One of the challenges was that the work would have to be done with us living abroad. 

Gil was a fantastic collaborator and had extremely good practical suggestions for the project. She was very thorough and expertly guided us through the application process.  Her designs were perfect for our needs and she was there every step of the way through the building and finishing process. 

We are extremely happy with the results and would not hesitate to seek her expertise again for future building and design projects."

"Gill offers a flexible and versatile service.  Our work entailed a new build garage and a conversion of an existing garage into a kitchen.  Gill spent considerable time listening to our ideas, ensuring she understood our requirements and showed great patience and desire to meet our needs.  She then added valuable practical advice and ideas from her extensive experience.

From first concept, to design & planning application (with subsequent approval) through to completion of the project Gill dealt with all aspects professionally and efficiently.  Her calm, friendly & approachable demeanor made it a pleasure work together."

R & B

"Our ideas and vision of reconfiguring and extending our house were transformed by Gill into reality.  Gill’s thoroughness and vision in the initial design and planning phases added aspects to the build that we may not have considered. Her knowledge of the planning processes and certification options ensured solid schedule and quality management and no major shortfalls in ensuring completion to the necessary local authority standards and building regulations.

We now have a house transformed from a basic modern house into a Home with a WOW factor that we are proud of!

We would not hesitate to recommend Gill Hayes to potential clients wishing to use Hampshire Design Consultancy."

C & M

"Gill has provided an excellent and professional service in helping us successfully obtain planning permission for an above garage extension.

She has been attentive in listening to our needs and provided some lovely design detail and ideas to create what I am sure will be a lovely new master suite.

Gill has always answered all of our questions (of which there were many!) in a most timely and efficient manner and continued to do so even after planning was granted. I wouldn't hesitate in recommending Gill & Mark in the future."


"Hampshire Design Consultancy provided us with plans for a kitchen extension which connecting it to our existing conservatory through new bifold doors. The outside appearance was modern as we had requested. Our builder found the plans easy to follow and we have delighted with the outcome. It fully meets the brief and we enjoy living in it."

T & C

"From the very first time I met Gill and Mark they put me totally at ease and no question seemed too stupid for them! They were very understanding about what I was trying to accomplish in my family home and really helped by suggesting ideas to maximize the space we were adding to the property. They are very family orientated themselves so I really felt they could 'see' what I was trying to accomplish and came up with a design which perfectly matched that. I had never done any kind of extension project before but they were both really helpful and kept me informed about the process and what was needed when. Their local knowledge about builders and who to use was also very useful.

They were very patient with me when I wanted any design changes (even during the build!) and I was absolutely thrilled with the end result - as I still am! The additional space is fantastic but the space itself has added so much benefit to our family in terms of how much more time we spend in it together (cooking, eating and playing!) and that was something that I could only hope for at the outset but has definitely been a huge tangible benefit to our family life. The extension itself is like a tardis - everyone always comments on how big it is when they come in even though it doesn't look that big from the outside.

I would thoroughly recommend Gill & Mark and will definitely be using them again if I need to undertake a project in the future."
