Langstaff Day Architects bring thoughtfulness to everything we do. We use creativity and experience to solve our clients’ problems. We pride ourselves on communicating clearly.

We enjoy collaborating with anyone who values good design and is looking to explore new ideas. We believe that the built environment matters. We want to help create a sustainable future.


/ Full Architectural Services

We can take full responsibility for a project from inception to completion and aftercare, as defined by the RIBA Plan of Work.

/ Tailored Architectural Services

We can offer a bespoke service specific to a project’s needs and budget in order to achieve best value for our client. The services might include some of the following:

  • Option appraisal to arrive at a concept design
  • Planning applications, with expertise in gaining permission for projects on tight sites or with a difficult planning context
  • Technical design and tender documentation, producing a detailed coordinated design suitable for costing
  • Construction information and site inspections to ensure the concept and detailed design intent is achieved during the building process

/ Feasibility Studies

We can unlock the potential of a site, space or building through early analysis of the opportunities available in sketch and model format. Through this critical process we can help to evolve a thorough brief and, where appropriate, consult with a range of interested parties.

/ Placemaking

From small scale temporary installations to larger scale masterplans, we can look beyond the boundaries of a site to address the relationship to a wider context and understand the implications of an intervention. Community engagement can form part of this process.

/ Sustainable Design

We are specialists in environmentally responsible architecture, embedding this into our wider design philosophy. As well as having a qualified BREEAM accredited professional within the practice, we have an extensive working knowledge of other assessment schemes such as Passivhaus and are experts in low energy architecture.

/ BIM (Building information management)

Our design and information production methods are at the forefront of current working practices. We are accustomed to working with 3D modelling software and in collaborative teams using BIM. We understand both the design coordination and facilities management advantages this can bring to a project.

/ Bespoke Interiors

We love attention to detail. We believe in the importance of texture, materials and colour. We can apply this to interior spaces, furniture and fittings to complement and complete a building.
