Form and structure
A simple, compact form is usually easier to build than a building with numerous recesses, bay windows and complicated junctions. A complex form can increase the amount of materials and labour and the number of details that require careful execution. This does not mean giving up bespoke architecture, but rather consciously assessing the impact of the solutions on the budget.
Roof and glazing
The type of roof, the number of roof planes, dormers, large glazing and non-standard joinery can affect both the cost of execution and the later performance of the building. It is worth considering their function, their orientation relative to the points of the compass and the technical requirements.
Plot and ground conditions
A sloping site, difficult ground conditions, a high water table or the need for additional earthworks can significantly affect the budget. That is why the analysis of the plot and an appropriate investigation of the ground conditions should precede the final design decisions.
Materials and installations
The choice of façade materials, joinery, heat source, ventilation, installations and automation systems should be considered together. A cheaper initial solution does not always mean a lower total cost, and more expensive equipment does not always bring proportionate savings. A technical and economic assessment is needed in the context of the specific building.
Scope of documentation
The cost of the design work also depends on whether the order covers a concept, a building design, technical or construction documentation, specialist designs and additional services. It is worth stating clearly from the start what the offer includes.
What to do next
Before you start designing, define an approximate budget, the most important priorities and the elements on which you do not want to economise. This allows the architect to look for solutions that match your assumptions.
