Build Service

What We Do

Zulufish also provide a comprehensive array of building and construction services, from basement conversions and house extensions to high-end fit out.

The foundations of any successful build are professional project management, quality control and skilled contractors. As we run only a limited number of construction projects simultaneously, we ensure each project is professionally managed and adequately resourced, delivering high-quality build projects within time and budget.

Our team of highly skilled project managers are all Prince II trained construction professionals and bring an additional layer of technical expertise, customer service and a wealth of experience to our projects. We manage project comms through a specialist construction project management software, with daily logs, meeting notes, progress pictures and all the latest drawings continually updated. Integrated within the software is our dynamic build timeline, viewable as a GANTT chart or calendar view, complete with all client milestones for key decision making.

Logging in through your computer or via our smartphone app, you can keep constantly up to date with both the progress of the build and the project finances, available to download at the click of a button. All change orders are submitted and approved through the software.

Since our inception in 2005 we have built up a strong core team of site managers and specialist trades, from carpenters and structural specialists to tilers and decorators. We are Safe Contractor approved and proud members of the Federation of Master Builders, use trusted NICEIC electricians and Gas Safe plumbers, and work with a select number of long-term trusted suppliers, such as stonemasons specialist paint finishers and structural glaziers.

We typically provide a full design and build service, but can also work to pre-designed plans and drawings, either directly for individual homeowners or as main contractor for a boutique selection of award-winning architects and interior designers.

These firms have come to trust us to deliver not only a superior finished product, but also to manage the build in a measured, timely and creative way. For construction-only jobs we work solely on a negotiated tender basis, we do not competitively tender.

The Process

Negotiated Tender & Contracting

Whether we are pricing off our own tender pack or a third party we produce a fully itemised and costed scope of works, ensuring our prices remain as competitive and comprehensive as possible. We are transparent with our pricing and will work with you to cost engineer the final scheme as required to fit your budget. Once the construction package is agreed we issue a JCT or FBM contract and deposit invoice to secure the start date.

4-6 Weeks
Meet the Team

Prior to starting on site, we set you up on our project management software and introduce you to your project & site manager, your key contacts throughout the build. We use bespoke project management software to produce dynamic timelines, log meeting notes and upload progress pictures, keeping you fully updated through every step of the project. You can download our app via smartphone or tablet or simply log in on your desktop PC.


During pre-commencement we create a dynamic timeline that highlights key stages and client milestones and is then dynamically updated through the build to track any changes to the critical path. We also notify all relevant parties to satisfy statutory obligations, such as building control and other applications to relevant authorities.

The Build

The site will be kept clean, tidy and fully compliant with Building Regulations and Health & Safety protocols throughout the build. Works will be carried out as efficiently as possible. Your project manager will meet you on site every week, with meeting notes and progress pictures updated every week, tracking each stage of the build. Payments received are documented so you have a reference point for managing your project cashflow, and any cost variations to the contract price are communicated and approved via the software.

12–52+ WEEKS
Practical Completion

Practical completion is when we sign off the house back into your care, after working through a list of final outstanding items.


After 6 months your project manager will visit to compile a snagging list with you and arrange a suitable time for the works to be carried out.

Services & Fees

We specialise in whole house refurbishment, basements and extensions and our build projects range from £100k – £2m+. All of construction projects are design-led, we don’t just build boxes on the back of houses or do identikit loft extensions. We focus on quality and design.

We are constantly checking our prices against the market and know we offer extremely good value for money for the comparable level of service and attention to detail.

We typically charge a 10% deposit on instruction, which is rebated against the monthly valuations along with a 5% retention, so you pay 85% of every valuation. 97.5% of the balance owed is released at Practical Completion, with the final 2.5% retained for the six month retention period.
