5th Generation Architecture

Cambridge

5th Generation Architecture was founded by Marilize Snyman-Harvey in 2007 and has gradually grown into a practice delivering excellent designs and buildings with great added value to our clients. Our reputation is being built on providing simple and stunning design solutions for individual client needs. Committed to deliver exceptional and affordable designs, we believe that good architecture and design should be available to everyone. We are concerned with ideas of sustainability through the use of energy efficient design solutions, detailing and technology, the choice of materials, the interaction of the building in its specific environment and the life-use of the building. Delivering buildings that future generations will enjoy and appreciate is the key to our thinking, and our buildings have a continuity of tradition in their design that makes them appropriate to their natural and built surroundings. We produce buildings appropriate for the local context, using traditional materials and modern techniques in a contemporary way to produce one off design solutions and buildings that complement our natural and built environments.

Dempsey Decourcy Architects

Ross on Wye

Derrie O'Sullivan Architects

Huddersfield

The Passivhaus approach to building design offers a tried and tested sustainable strategy which is meaningful because it is measurable in its use of energy and has no equal in our temperate climate. The methodology employs a combination of super insulation, appropriate areas of superbly designed triple glazed windows and doors for optimum beneficial solar gain, air tight construction with a heat recovery ventilation system ( MVHR) to achieve a space heating consumption of less than 15kWh/m2yr: which is vastly superior in comparison to the current UK Buildings Regulations which is in the order of 120kWh/m2yr. Passivhaus is the most cost effective way to save our finite energy resources and offers a high quality of thermal comfort for the people who use and live in the buildings.

Gresford Architects Ltd

London

Gresford Architects seek to create buildings that are thoughtful, practical, sustainable and beautiful. We are interested in how spaces (and the buildings that create them) make us feel; how every decision that goes into creating a space – the materiality (surfaces, joints, planes, textures), the positioning of the windows and doors, of lighting and heating – must be carefully considered to allow the perfect marriage of the poetic and the practical. We have a fundamental belief in the importance of building in a sustainable manner, so that the buildings we create last for generations, are efficient in their use of materials and energy (in both construction and use) and are comfortable and pleasant places to be. We have a Certified Passivhaus Designer among our staff and will soon be recognised as a Certified Passivhaus Designer as a practice. We believe that the Passive House Planning Package (PHPP) is a tool that should be used to help design and inform the creation of new buildings from the outset, and encourage our clients to see the long term benefits of the early adoption of PHPP modelling on their projects. We also work with a wide range of experienced Passivhaus consultants, contractors and subcontractors, and can thus help our clients put together the right team to deliver their projects.

Our engineering design solutions are developed uniquely for each project of any size rather than an off the peg engineering solution. What distinguishes KSA in delivering Passivhaus projects, as an energy and occupant comfort standard, is the use of thermal modelling for predicting any issues during the design stage (ie. overheating, condensation, thermal comfort). Various design and construction alternatives (U-values calculation, solar control methods, passive design strategies and others) are then provided.

Harrogate

Shaw and Jagger Architects offer specialised consultancy in Passivhaus design and PHPP analysis on our projects. We can engage with this exceptional world leading standard of construction early on in the concept stages of design to achieve optimal performance and comfort yet always still maintain strong focus on architectural design and proportion. We are liberal in our approach to all types of construction and styles of architecture to which we can apply Passivhaus. Renovation and deep retrofit offers the opportunity to develop projects to EnerPHit, sometimes by Component Criteria rather than energy performance, if the limitations of the building are too great. We can work with you to greatly improve levels of comfort, control of mould growth, air quality, energy consumption, daylight and projected lifetime of your home with the ethos and application of Passivhaus.

I have many years of experience working with National developers, on residential layouts and commercial architectural design. I am highly practical and motivated by good design both modern and traditional. Sustainability is a key word in these days of environmental consciousness, and my designs take this as a fundamental base, to achieve both client aspirations and Governmental requirements. To this aim I am actively pursuing modern methods of construction including Passive Houses.
