Architecture / June 2, 2018 / .
In general it can be said that larger buildings with simple, rectangular, regular floor plans and elevations will be less expensive per sq.m. of floor area than smaller, complex shaped, curved or angular buildings. Economies of scale apportion fixed overheads to a larger extent of productive space. Simple setting out and buildable solutions encourage greater plant use and generate higher productivity and less waste. Complex layouts and details are slower to assemble and may involve a number of trades with a consequent greater risk of mistakes and defects. The degree of compartmentation and repetition will also affect the overall cost of the work. New building work is considerably cheaper than work of a repairing nature or work in existing buildings. Single storey structures tend to be more costly than buildings up to three storeys high, beyond which point they become progressively more expensive.
In many ways, designing and building a home is very complicated. But in at least one way, it is very straightforward. A house cannot be a dream home unless you fully understand the clients needs. Every luxury home should be unique to its occupants. When designing a home, start with asking a lot of questions. Talk with them, listen to their needs, understand their wants, and help to translate those into a design and plan. Questions about how you live day-to-day in your home are the key. From the answers to these questions, we will create a list of priorities, which we then work with to determine what the right size and level of quality needs to be.
The factors influencing this decision include: Is the more expensive option a worthwhile investment? If it can be demonstrated that savings will arise as a consequence of incorporating the more expensive alternative, then the client is well advised to choose this option. The quicker the payback period, the more likely it is that the more expensive option will be chosen. How flexible is the client‟s budget to finance more robust, better quality or more economic structures or systems? Regardless of whether the client wants the more expensive alternative he or she may not be able to afford it. Retrofitting, however, is inconvenient, disruptive and much more expensive subsequently. Will the client occupy the building? Clients who develop to sell or lease may be less concerned with the operating and maintenance costs of the facility which will be passed onto the eventual purchaser or user of the facility. Clients who spend more initially will seek to recover their investment through higher rents or sales price. This approach may be adopted by future oriented private sector clients concerned with sustainability and green building issues. What is the life-span of the building? The shorter the planned life span of the building the less appropriate it is to incorporate robust and durable materials and systems.
The choice of the architect as lead designer is a key decision on any project and will reflect the clients priorities, particularly those related to cost and quality. Clients who plan to develop high quality or landmark developments often employ high profile design practices. Indeed internationally acclaimed architects including Daniel Liebskind, Santiago Calatrava and Dublin-born Pritzker prize-winning Kevin Roche have completed projects in Dublin in the recent past. The leading Irish architectural practices are likewise normally in high demand and clients are keen to buy into their signature. High expectations are usually linked to high prices and such clients will expect to pay a premium on prestigious projects. Nevertheless, they may not be prepared to provide total carte blanche to the architect. Architects, quite naturally, may be reluctant to drop quality standards and compromise their brand to reduce costs and it may difficult for the quantity surveyor to control costs in these circumstances. In this regard Ashworth refers to a cynic who described architecture as the design of beautiful buildings that satisfy only the architect and not the client. At the other end of the cost spectrum a client may require a practical, nononsense design to accommodate a production process. Such designs are often developed by architects operating within a design and build arrangement where providing an economic design is essential to winning the contract.
