Heritage Home Extension

Specialist extensions for listed buildings and heritage homes using traditional methods combined with modern VR visualisation. Our team ensures compliance with planning regulations while enhancing property character. Projects include structural surveys, 3D design iterations, and contractor coordination to deliver functional, period-appropriate extensions that increase property value and usability.

Listed Townhouse Conversion

Expert conversions of Glasgow's listed townhouses with 23 completed projects. We navigate complex planning requirements while preserving architectural integrity. Services include heritage impact assessments, virtual reality design reviews, and project management from initial concept to building warrant approval, ensuring historically sensitive yet modern-living compliant transformations.

3D Modelling Design

Advanced 3D modelling and virtual reality tools enable real-time design collaboration. Clients experience spatial layouts and lighting effects before construction begins. This technology reduces costly revisions, ensures accurate planning submissions, and allows precise material selection, resulting in better-informed decisions and highly satisfactory outcomes for residential and commercial projects.

Project Management

Comprehensive project management from planning approval to completion. Our services include contractor tendering, budget control, regular site inspections, and defect resolution. We coordinate structural engineers and building warrant applications, ensuring compliance with regulations while maintaining design integrity throughout the construction process for both domestic and commercial clients.

Virtual Reality Visualisation

Cutting-edge VR technology allows clients to walk through proposed designs before construction. This interactive process enables real-time adjustments to layouts, lighting, and finishes. The immersive experience reduces design uncertainties, improves planning accuracy, and ensures final outcomes precisely match client expectations for heritage and modern properties alike.

Allison Architects designed the large scale renovation project of our Edwardian house. The brief wasn't straightforward because it not only involved complete overhaul of a half of downstairs but also creating bedrooms in the attic space. We also wanted crisp, modern architectural style, a bit of mix of Scandinavian and Japanese styles.
Allison Architect came up with brilliant, creative design solutions to our brief which made the most of available space and also created a bright and sociable open plan kitchen/diner/living area in the downstairs. We were impressed with their ability to turn our

Twice we arranged to meet Stephen and twice he did not show up. The first time he contacted us afterwards to advise he had a family emergency so we agreed to reschedule. The second time was a no show again and this time there was no contact afterwards. I am sure Stephen is a very good architect but our experience was extremely unprofessional and we count this as a lucky escape. We had also made childcare arrangements on both occasions (involving significant travel) so others were inconvenienced also.
