About Us

Founded in 2003 by Barbara Hartley, Garsdale Design has worked on a range of projects, from domestic architectural projects, large international planning projects, and 3D geodesign projects.  Our 3D geospatial, urban modelling, and Esri CityEngine projects are operated under our brand GD3D by Elliot Hartley which has a separate website located here.


Our Approach

Domestic projects are always personal and should be tailored to individual needs regardless of size. Therefore, we work closely with clients to find the best design solution. Then we undertake the often complex and demanding process of obtaining planning permission, and building regulation approval where this is needed.  We provide an inclusive service where planning documentation is required, including heritage assessment and design & access statements.

Our international projects are often carried out with local partners or as part of a team of consultants. We can undertake the most complex masterplanning projects for city regeneration. These often involve detailed urban design proposals for pilot projects where we can use 3D urban modelling and visualisation techniques.

We always listen to a client’s needs and work hard to produce the optimum solutions that benefit the project whether it is large or small. We recognise there are constraints of time and money for many projects. Therefore, a structured approach based on experience is vital for a project to run smoothly.

We aim to place planning and design excellence with a sound commercial approach at the service of our clients in order to create carefully tailored solutions.


Our Partners

When appropriate we form partnerships with other companies to best serve our clients.

Founder / Director

Barbara Hartley

MA (archaeology & Heritage) RIBA Chartered Architect

Barbara is the founder Director of GDL and a Designer and Heritage Specialist with some 50 years’ experience in Cumbria, Yorkshire, Liverpool, Sussex, Kuwait and Oman. She operated as a sole practitioner near East Grinstead before becoming a director of Luc Markies Associates of Forest Row for 10 years. As such she was responsible for a wide range of commercial and residential projects in south east England.

In the mid-1990s she moved to Kuwait and took up a post as Senior Architect with the leading Kuwaiti firm of Salem Al-Marzouk and Sabah Abi-Hannah.  Here she was responsible for major commercial and residential projects in the city centre and outlying towns. These included a 16-storey tower building for a major insurance company.

Afterwards she was appointed a Senior Architect with WS Atkins International & Co in Muscat.  While resident there she undertook major residential, tourism and leisure projects in for a major hotel chain Muscat and elsewhere.  Barbara was the Project Architect for the prestigious company township for Oman LNG at Sur which was designed, built, and occupied in a record time of 20 months.

On return to the UK in 1996 she set up Garsdale Design to pursue residential, social, and commercial projects throughout the Yorkshire Dales and north west England. She took a part-time masters’ degree at Leicester University in archaeology and heritage in order to inform the heritage commissions she was given.

Over nearly 20 years Garsdale Design has undertaken over 500 residential and commercial commissions, many of which have involved preparation of Heritage Assessments for listed buildings. As a result, Barbara is now a leading local expert in the conservation of traditional buildings and how planning permission can be obtained for them.

From 1997 to 2002 he ran the Muscat office of WS Atkins as Resident Director undertaking a series of major projects throughout the Sultanate over six years. He then moved to become a Director of Planning and Architecture at Shankland Cox in the UAE, before returning to the UK to set up Garsdale Design with Barbara Hartley as a founder director.  From its base in the Yorkshire Dales he has been responsible for re-planning major cities in Iraq, including Kut and Kufa, the first plan for Duqm New Town in Oman and a series of major leisure and tourism projects in Oman and East Africa.

He has worked for more than 20 years in GIS, planning, 3D urban modelling, and geodesign as a senior planner in the private sector, and a Development Control officer within local authority planning departments. Elliot’s academic career has seen him specialise in Geographic Information Systems (GIS) and Town and Country Planning.

He has worked on a diverse range of projects from processing planning applications to managing digital transformation of a local planning authority and from urban planning, to geospatial analysis, cartography, and 3D visualisation for city master planning projects.
