Our approach
Good design begins with understanding.
Every project has its own story. At KEEP, the best outcomes come from listening carefully, thinking openly, and resolving every detail with purpose.
Creative ambition and technical rigour belong together. We bring both to the table, shaping spaces that feel right and work beautifully in the real world.
A modern stronghold.
When emotional and architectural meanings combine, the building becomes a symbolic stronghold:
- A place that keeps life safe, calm, and grounded
- A structure that keeps stability through its form and materials
- A layout that keeps occupants protected and supported
- A home that keeps identity, memory, and belonging intact
This is the modern reinterpretation of the medieval keep — not defensive, but anchoring, protective, and emotionally central.
Our process
From possibility
to place.
A considered design process, grounded in experience and made for the way you want to live.
00
Site visit / pre-purchase consultation
Early advice on site constraints, planning requirements and budget considerations before design work begins.
01Project and site feasibility
A fixed-price report on what your site can deliver: planning controls, site constraints and services, approval pathway, dwelling yield and a fee proposal.
02
Pre-design and concept design
Considered spaces shaped around how you live, work and connect.
03
Design development and planning application
Creative ideas refined into practical, buildable design solutions guided by the planning requirements, including preparation of the documentation required to lodge your application.
04
Construction documentation
Detailed working drawings and specifications, coordinated with engineers and other consultants and prepared to meet the National Construction Code, ready for certification, builder pricing and construction.
05
Costing & quoting
Cost estimates as the design develops, then tender documents issued to builders and their quotes compared like-for-like, so you can choose a builder with confidence and keep the project on budget.

- What the planning controls allow on your site
- The likely approval pathway: complying development or development application
- A concept yield sketch showing how many dwellings fit
- Site constraints and obstacles, including utility services, and what they mean for cost
- A fee proposal for the full design

His communication has been outstanding, and his advice and guidance have made the entire process straightforward and stress-free. We would not hesitate to recommend him to anyone undertaking a similar project.
Richard from Keep Building Design was highly professional and very helpful when I had questions about areas of the development I wasn't sure about.
Would highly recommend his service!
