Howarth Litchfield architecture is driven by the pursuit of quality, excellence of design and its successful execution.

We believe that surroundings directly influence the quality of our lives.  Allied to that is an acknowledgement that architecture is generated by the material and spiritual needs of people. We care  for the physical context, the culture and the settings of our designs

Sustainability is integral to all the design work from HL and a discipline in its own right. Our knowledge of building performance, technical standards and technology combine to help clients, M+E engineers, and end users gain maximise efficiency and enjoyment from their projects.

As architects and designers, we must seek to design new buildings to gain from orientation, sunlight, ventilation, and views. We must preserve and enhance existing building stock to be fit for the current age, whilst being sensitive to historic and traditional methods of construction.


Projects executed by 3HL take full advantage of the Practice’s practical approach to project delivery.  What that means to the owner and client is time & cost savings with maximum quality for their projects. Rigorous discipline in the use of our project delivery system is the best protection offered against cost overruns during construction.

We are well placed to work alongside existing Project Mangers as our Design Project management compliment for the benefit of the delivery of the specific project.

Our approach to the management of pre- construction, construction & post-construction stages utilises industry recognised scheduling, project control techniques and computer applications. Our vast range of design project management services include:

RIBA Client Design Advisors a service promoting high quality and best value in building When considering the built environment, the most important decisions are the ones made at the very inception, before the planning and design stages and long before any bricks are laid.

It is at this early stage that the success, or otherwise, of your project is decided. Getting answers to questions such as those listed opposite is a challenge for any construction client, whether it is their first project or their fiftieth.

An RIBA Client Design Advisor is usually an architect (but not the one designing the building) sitting on the client’s side of a project, independent of the supply team, monitoring and helping to manage the design process from its earliest stages.

It’s a vital role on all projects, for example Private Finance Initiative or Design and Build where the clients access to the executive design team is often limited. An RIBA Client Design Advisor will:

  • Explore high-level options for meeting your business or strategic need. Is a new building the best solution or can better use be made of your existing estate?
  • Carry out strategic risk assessments of the project.
  • Identify lessons learned from previous experience of similar projects.
  • Define an agreed set of project outcomes.
  • Consult key stakeholders to identify significant project issues.
  • Prepare feasibility studies and a strategic business case for the project.
  • Help set a budget and propose a funding strategy, taking into account Identify and develop the most appropriate procurement strategy for completing the project on time, to budget, to the quality required.
  • Ensure that the project is compliant with the original brief to ensure that you, the clients, are getting what was originally asked for. Where changes are unavoidable, divergencies or modifications will be agreed and reported as necessary.
  • Prepare the outline business case.
  • Prepare a full project brief, output specification and sustainability goals.
  • Apply for planning permissions.
  • Manage the invitation and evaluation of tenders from design and construction teams.
  • Check budgets, design proposals, construction details and project documentation.
