🧱 What Does a Shell-Only Construction Package Include?

If you're planning an extension, new build, or commercial project, you'll hear the term "shell-only" thrown around a lot — but what does it actually mean?

At ShellCo Ltd, we specialise in shell-only construction across Hertfordshire, Bedfordshire, and Cambridgeshire, working with homeowners, developers, and main contractors to get the core structure up — cleanly, quickly, and professionally.

Here’s a breakdown of exactly what’s included when you hire ShellCo for a shell package:

🏗 1. Groundworks

We start with full site prep and foundation work:

• Site clearance

• Trench footings

• Oversite (screed, hardcore, or block and beam)

• Drainage installation

• Manhole and ducting coordination

  
  

Everything we do is aligned with building control and engineer’s specifications.

🧱 2. Structural Masonry

We build your external and internal structural walls:

• Brickwork (outer skin)

• Blockwork (internal or cavity)

• DPC layers, insulation install, ties and weep vents

• Any padstones, lintels or supporting walls

  
  

🧰 3. Structural Openings & Steels

• RSJ and steel beam installation

• Formation of door and window openings

• Brick reveals, concrete lintels, and bearing pads

Whether you’ve got bifolds, gables, or large knock-throughs — we handle the heavy stuff.

🏠 4. Roof Installation

Depending on your plans, we supply and fit:

• Trusses or traditional timber roofs

• Felt, batten, and tile

• Verge work and lead flashing

• Optional dormers or flat roof structures

Everything is made weather-tight and safe for the next phase.

🔒 5. Site Cleanliness and Hand-Off

Once the shell is complete:

• The structure is watertight

• All brickwork and roof work is signed off

• Site is swept and clear for interior trades

We also coordinate with your electrician, plumber, or architect where needed to ensure a smooth transition.

🧾 What’s Not Included?

Just to be clear — shell-only does not include:

• First fix plumbing or electrics

• Internal insulation, plasterboarding or finishes

• Kitchens, bathrooms or painting

• Flooring, tiling or heating

If you're looking for a full build service, we can refer or coordinate — but our specialty is getting the core structure up to spec, fast.
