Luke Williamson Architect can provide architectural services from project inception to completion.
For most domestic projects we would provide fixed quotes for our Work Stages A, B & C (updated for 2025). Architectural Services for tendering and during construction are available if requested and quoted separately or based on an hourly rate.
Ours fees start from:
£600 for Work Stages A (measured survey, existing drawings, review of client brief/budget etc.)
£1200 for Work Stage B (proposal options/meetings, Planning drawings and submission etc.)
£1200 for Work Stage C (Building Regulation drawings, construction notes etc.)
The fees above reflect a project involving a storey rear to a house with limited internal changes and relatively local to our office location.
Our typical timescales are noted below:
1 – 4 weeks
From our initial visit we aim to provide a fee agreement for review within a few days. From appointment we typically have a 2-4 weeks lead-in time before we progress the project and arrange the measured survey.
4 - 6 weeks (Design)
Our design process takes between 4-6 weeks, with options being considered and reviewed with our client during that time. Clients are often keen to get a Planning application submitted, however, this is the most creative stage, so an extra week or 2 finalising a scheme is well worth the time.
8 weeks (Planning)
Once submitted the local Council typically decides on an application towards the end of an 8 week review. Assuming the scheme is approved, timescales would move on to Work Stage C.
4-8 weeks
Preparation of our Building Regulation information for submission and builders quotes takes around 4 weeks. We also liaise with other consultants during this stage, typically a structural engineer, and their input and involvement also takes 2-4 weeks to coordinate and integrate.
3 – 4 weeks
Builders often take at least 3-4 weeks to provide quotes.
3 - 6 months.
This timescale very much depends on the Contractor, however, extensions typically take between 3 to 6 months to complete. Large schemes can take up to a year.
As part of our standard services, Luke Williamson Architect undertakes the duties as 'Principal Designer' under Building Regulations and CDM for our Work Stages A, B & C.
The following Stages are optional services that we can provide if requested.
