Why one team
Your time should not be the thing holding the project together.
Most projects are split between a designer, a planning consultant, engineers, a contractor, an interior designer and a building manager. Each holds one piece, none is accountable for the whole, and the owner becomes the coordinator by default.
We hold the brief, budget, programme and standard of finish together, lead every consultant and trade, and ask for your decision only when it genuinely matters.
Without a single lead
- Six or more separate appointments
- Gaps between drawings, consents and site
- Cost and programme risk sits with you
- You chase answers
With Hosannahs
- One appointment, one accountable team
- Design, consents and site coordinated
- Change control and certified payments
- You receive clear reports and decisions
Full-scope turnkey delivery
Everything between the brief and the keys.
Appraisal and design review
Feasibility, options and costs tested before you commit, including critical review of existing schemes.
Planning and consents
Planning, prior approval, listed building consent, building regulations, freeholder licences and party wall.
Structural and M&E coordination
Structure, services, fire and acoustics brought into one coordinated set of information.
Procurement and construction
Competitive tender, a recognised building contract and a site managed to specification, budget and programme.
Interiors and FF&E
Led by a BIID Registered Interior Designer: furniture, lighting, art, styling and photography.
Handover and aftercare
Certificates, manuals and warranties in one file, keys handed over and the defects period managed.
For funds and family offices
Governance you can report upwards.
The controls an investment committee or trustee board expects, built into every project as standard.
One senior lead
A named person who knows the project in full and answers to you or your nominated adviser.
Regular reporting
Concise fortnightly reports: progress, photographs, cost against budget and programme.
Change control
No variation proceeds without its cost and time agreed in writing, and every decision is logged.
Cost certainty
A recognised building contract, and contractors paid only against certified valuations.
Insurance and safety
Professional indemnity cover in place. Health and safety duties managed under the CDM Regulations 2015.
Discretion
NDAs as standard on request. No hoardings, publicity or social media without your written consent.
How a project runs
Nine stages. One team. Your time only where it counts.
The tag on each stage shows how much of your time it typically asks for. We carry the rest.

Ways to engage
As much or as little as you need.
Every engagement begins with a brief and appraisal, which can be commissioned on its own. Fees are agreed in writing before each stage begins.
Stages 1 to 5
Design and Approvals
A designed, consented and coordinated scheme, ready for any contractor to price.
Best for owners with a trusted contractor.
Stages 1 to 6
Design, Approvals and Procurement
Everything above, plus a competitive tender and a contractor appointed on clear terms.
Best for investors with in-house project management.
Stages 1 to 9
Turnkey
One point of responsibility from first appraisal to keys in hand, including construction and interiors.
Best for clients who want the result, not the process.

Your senior lead
“A refurbishment in a prime building should add to an asset, not draw on its owner’s attention week after week. Our job is to carry that weight for you.”
