Technical & Construction Pack

Full budget visibility from the first stage
From the Feasibility & Concept Design Pack onwards, you receive an indicative budget that covers not only the construction costs but also the professional and statutory fees your project will need. As the design develops, the estimate becomes progressively more detailed and accurate, so you stay in control of your budget at every stage and can make decisions with the full picture in front of you.
Frequently Asked Questions
Which RIBA stages does this pack cover?
RIBA Stage 4 (Technical Design) and Stage 5 (Manufacturing and Construction) of the RIBA Plan of Work.
Do I need Building Regulations approval if I have planning permission?
Yes. Planning permission and Building Regulations approval are separate. Most extensions, loft conversions and conversions need Building Regulations approval, even when they are permitted development.
What is a tender package?
A set of drawings, specification and schedule of works that describes the project in detail, so that different contractors price exactly the same works and their quotes can be compared fairly.
Why are detailed drawings important for the budget?
The more detailed the drawings and specification, the more accurate the contractors’ prices, and the lower the risk of extra costs and disputes during construction.
Do you visit the site during construction?
Yes. We offer site visits and support during construction, with the level of involvement agreed with you at the start.
