Our Studio

Founded by Principal Architect Sandy Lees in 2010, AGL Architect is based in Bannockburn in Central Scotland.

We’ve developed a client base that is spread right across the country, from Hebridean Islands to the cities of Edinburgh, Stirling and Glasgow.

Our personal and friendly approach, coupled with contemporary designs and competitive fee structure, mean that much of our new business comes from referrals from happy clients.

We work on architectural design projects of all sizes. From large scale masterplans for regeneration projects and new developments to small house alterations and extensions, we bring the same experience, enthusiasm and collaborative approach to create contemporary designs that meet the brief and delight our clients.

New Church Hall
“Dear Sandy,

Over the last 4/5 years we have worked together on two projects at Lecropt Kirk where I serve as the property convener. These contracts were made so much easier with your proactive approach to what the client actually required from the end results The new Kirk hall was developed via a feasibility study that we discussed with Stirling planning department where we all established a quick way forward in the production of the actual agreed design.

The hall was built over some six months where the project team had various amicable friendly discussions leading to a comfortable conclusion meeting all the client’s needs.
The interaction we had on the project made my responsibility to Lecropt Session an easy task in that what was decided actually took place.

I have pleasure to recommend your practice for future works at Lecropt Kirk and within the Church of Scotland where your high standards will be appreciated.
Thanks again for your support.”

Proposed Internal Alterations & Extension to Dwelling House
“We approached Sandy and AGL to confirm that the plans we had in our heads for an extension were workable, and he immediately put our minds at rest. Working alongside Sandy to bring our ideas to life was an absolute pleasure. He kept us right with all the structural requirements and his suggestions to allow more light and more space into the house were so helpful.

Sandy was always very open and gave us the options with which we could work through the project with him. No matter the little changes we wanted to make, or the stages we had to meet with the council and regulatory bodies, Sandy was always there to answer all the questions and advise the best course of action.

We are delighted with the work that Sandy and AGL have done for us, and most importantly, we’re delighted with our new extension. We can definitely highly recommend AGL to anyone who is considering a build. He came to us as a recommendation and we were absolutely not disappointed.”

New Dwelling House
“Sandy Lees was the third architect we approached to design our house and he was absolutely the right choice.



He is a good listener and came up with a little sketch (he is a good draughtsman) that was just as I had been imagining and from there we went on to create a wonderful house that answers all our requirements and more. It is a very pleasing home to live in. He was always available to us by phone, email, or person … and he had a good relationship with our builder (which is not always the case!).

He was also great at dealing with all the red tape of Building Control, etc . I really enjoyed the whole process of working with him and recommend him highly to any future client.”

Janet Nelson, Isle of Mull

Supporting our Communities
