You may be a landlord or tenant wanting to see what options are available and how feasible refurbishing or extending your property is. 

You may be a real estate agent or property developer wanting to use a feasibility study to help with an existing/new client property to assist with the sale and provide that extra competitive edge that your competitors lack.  


Or you might own your own office, barn or residential accommodation and looking for a change of layout or wanting to extend.  


Well, look no further - Sphion Ltd can assist you through the process. 


Feasibility studies are preliminary studies undertaken in the very early stage of a project. They tend to be carried out when a project is large or complex, or where there is some doubt or controversy regarding the proposed development. If an environmental impact assessment (EIA) is required, this may involve assessments best undertaken as part of feasibility studies.  


  • Establish whether the project is viable.

  • Help identify feasible options.

  • Assist in the development of other project documentation such as the business case, project execution plan and strategic brief.


On large or complex projects, there may be a number of different feasibility studies carried out, sometimes requiring different skills, and considering issues such as:  

  • Planning permission.

  • The likelihood that an environmental impact assessment will be required.

  • Other legal / statutory approvals.

  • Analysis of the budget relative to client requirements.

  • Assessment of the potential to re-use existing facilities or doing nothing rather than building new facilities.

  • Assessment of any site information provided by the client.

  • Site appraisals, including, availability of services, uses of adjoining land, easements and restrictive covenants, environmental impact and so on.

  • Considering different solutions to accessing potential sites.

  • Analysis of accommodation that might be included or excluded.

  • Assessment of the possible comparison of accommodation and preparing basic designs.

  • Assessing operational and maintenance issues.

  • Appraisal of servicing strategies.

  • Programme considerations.

  • Procurement options.


Various stakeholders, statutory authorities and other third parties may need to be consulted in the preparation of feasibility studies.  

Sphion's assessments will be presented in a structured way so you, the client, can decide whether or not to proceed to the next stage. Do not hesitate to contact us to see how we can help with your building needs.

Design and specification work hand in hand for a successful project. Sphion Ltd is highly experienced in providing innovative, professional design and specification advice.  

We have experience from designing new school extensions from classrooms to hall extensions, building your dream open-plan kitchen and dining room extension, warehouses and office extensions. We also have experience acting as Technical Advisors.

Sphion takes the time and listens to your building needs and helps bring them to reality. We live in a 3D virtual world so why wouldn’t you want to see your new project in 3D. Many people struggle with understanding 2D drawings and need extra assistance with visualisation.


We at Sphion are experts in AutoCAD, Revit and Sketch Up and have a number of trusted architectural technician sub-consultants who can provide architectural 3D visualisations using Revit and other forms of 3D software.


Design is our passion - we carefully articulate your clients brief and work with you hand in hand resulting in cost effective, sustainable design solutions for any building project.

We tailor a specification to suit your building needs. Specifications describe the materials and workmanship required for a development.

Specifications vary considerably depending on the stage to which the design has been developed, ranging from performance specifications (open specifications) that require further design work to be carried out, to prescriptive specifications (closed specifications) where the design is already complete.


At Sphion Ltd we provide a professional, innovative service developing design and specifications, increasing in level of detail as the design progresses. This way the specification and design can be sent out to tender, to a number of contractors making it competitive and getting the best value for your money. We can also project manage your project.

Building Regulations set out the acceptable standards for functionality and health and safety in and around buildings by imposing certain functional requirements for the design, construction and alteration of buildings.


The regulations also impose certain standards to promote the energy efficiency of buildings and the needs of disabled users.


Sphion can submit your Building Regulations application. This includes technical detailed drawings including cross section of any new proposed works.

Building Regulations and Planning Consent are not to be confused. These are different application processes, under different legislation and regulated by separate Local Authority departments.


All alterations, extensions and new building work needs to comply with Building Regulations. The building regulations apply to many different projects from large to small. With regard to households for example this could include extensions, loft conversions, knocking through between rooms, moving or creating a new toilet or bathroom, electrical work, window replacement and converting a garage to name but a few typical residential household projects.

Thinking about moving accommodation? Have you thought about looking at the existing space in detail before you think about an expensive move? Or have you just purchased a new premises and want to maximise your space?

Space planning is a cost effective approach to see how your existing assets can work for any of your building needs. Carter’s Building Consultancy has an eye for detail when it comes to spaces and their potential parameters.

Before we examine the overall form, appearance, size and what we can actually fit in the space, such as physical ability of the building to accommodate overall spatial and volumetric requirements of the proposed new use. We suggest to analyse the structure and construction of the property first of all, so that the ability of structural layout to permit spatial requirements/ relationships of use to be met getting a feel of the property and understating its limits and constraints.

With this in mind we can look at the extent to which structural form/layout can be altered/adapted to suit the new needs. By doing this it will help understand the building's ability of structural systems to allow new elements to be introduced such as partitions, services and staircases. Furthermore, by doing this it will highlight the extent to which functional requirements of the new use may be compromised by the constraints of the structural arrangement.

We provide a detailed existing plan showing these characteristics, so everybody understands the building as we do. From this we get a good understanding of the building and able to provide a solution for your spacing building needs. We have the ability to show 2D plans and 3D architectural illustrations of the internal layouts giving a clear and professional service. The plans will be in line with current design guidance and building regulations.

Space planning can improve office layouts arranging so that staff can work together in departmental and team groupings, providing the best opportunity for efficient work flow, communication and supervision.

Space planning is one of the key measures of workplace performance. Apart from the financial savings, there’s the legal requirements, accommodation standards, staff welfare, telecoms to take into consideration.
