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.

Walk-through

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.

Lulu, Creative Director at Hosannahs

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.”
