What this work involves
Separate what the plot allows from what you need in everyday life. A schedule of rooms helps coordinate architecture, building services and finishes from the beginning.
- Requirements and plot information
- Design, structure and investigations
- Construction system and materials
- Heating, energy use and ventilation
- Finishes, landscaping and handover documents
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Identify which existing elements an addition needs to prepare now.
Which trade-off matters?
A complete approach can improve coordination, while phased work spreads the budget. Compare which junctions would need reworking after a delay and which elements can be completed independently.
What the drawing needs to explain
Create a phase drawing with three colours: repair now, improve later and investigate first. Mark where phases meet, such as roof edges, service routes and finished floors.
Decide this before construction
Address assessed causes of defects before new finishes conceal them. Plan comfort measures together with ventilation and necessary access to building services.
Cost factors for this service
A complete budget includes more than the construction price. Keep design, investigations, connections, authority fees, landscaping and finishing choices visible.
Bring this to the discussion
Plot information, room requirements, existing drawings, preferred timing and budget priorities.
Questions about the work
When does a budget become reliable?
When the design, technical assumptions and finish level are sufficiently defined. Early estimates remain dependent on assumptions and provisional sums.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
