Homeowners, self-builders and developers in Birmingham often ask what is included in new build shell construction. Two shell quotes rarely cover the same work. Gora Bricklayers builds foundations, blockwork and brickwork for new homes across the city. This guide sets out what a shell normally covers, what usually sits outside it and how to read scope. Anyone planning a new build in Birmingham can then compare quotes like for like.
What Is Included in a New Build Shell? The Short Answer
A new build shell is the structural stage of a house. In brick and block construction, that normally means foundations, a ground floor and external cavity walls. Internal structural walls, lintels and damp-proof courses complete the core list.
A typical brick and block shell commonly includes:
- Foundations and substructure, where the contract starts at ground level
- External cavity walls built in brickwork and blockwork
- Internal load-bearing walls and other structural partitions
- Lintels over door and window openings
- Damp-proof courses and cavity trays
- A beam and block ground floor, where the design specifies one
- Wall or floor insulation, where the package covers it
Scope still varies between contractors and projects. Roofing, windows, external doors and finishing trades may sit inside or outside the price. The signed contract, drawings and specification decide what a shell includes.
What Does New Build Shell Construction Mean in Practice?
Contractors use the word shell in two common ways. A structural shell covers foundations, floors and walls built to a stated stage. A weathertight shell goes further, with walls, roof, windows and doors all in place, according to Homebuilding.
Homebuilding also describes a shell-only contract as foundations, drainage and main structure delivered to a weathertight stage. The owner then manages the remaining work. Two quotes called shell can therefore stop at different points on the same house.
On shell stages, Gora Bricklayers focuses on the masonry side of that scope. Its Birmingham new build construction services cover foundations, blockwork, brickwork and agreed structural stages. Work beyond that stage, such as roofing or glazing, needs its own agreed scope.
Which Foundation and Substructure Work Belongs in a Shell?
Foundations and Excavation
Foundations carry the whole building, so shell scopes that start at ground level usually include them. Some contracts begin above the slab and leave groundworks to another contractor. Ground conditions vary across Birmingham, including made ground on some former industrial sites, so the engineer’s design follows site investigation.
Ground Floor and Beam and Block
Where the design specifies a suspended floor, beam and block often forms part of the shell. This system uses precast concrete beams with infill blocks, so it avoids pouring a full slab. Insulation, membranes and screed above the beams may be priced separately, so quotes should name them.
Drainage and Service Entry Points
Homebuilding lists drainage and provision for incoming services among the items a shell contract can cover. Pipe routes and entry points are usually easier to allow for during the build than to add later. Clients should confirm that the price covers below-ground drainage and service ducts.
What Do Brickwork, Blockwork and Cavity Walls Include in a Shell?
Brickwork and Blockwork
External walls usually combine facing brick on the outside with block on the inside. Internal structural walls often use block, with the type set by the engineer and the drawings. Gora Bricklayers builds this masonry across Birmingham, from custom family homes in Edgbaston to multi-unit developments in Northfield.
Load-Bearing Walls and Internal Structure
Load-bearing walls carry floor and roof loads down to the foundations. The structural engineer identifies which walls do this, and removing one later needs a replacement support. Non-load-bearing partitions may be built in block or framed later, so the scope should say which.
Cavity Construction, Insulation and Damp-Proof Courses
A cavity wall has an outer leaf, an inner leaf and a gap between them, held together with wall ties. Damp-proof courses and cavity trays resist moisture crossing the wall or reaching openings, and Approved Document C covers moisture resistance. Cavity or board insulation is included only where the package says so, and Approved Document L sets thermal performance.
Which Lintels, Openings and Structural Steels Fit Into the Shell?
Each window and door opening needs a lintel, a beam that carries masonry above the gap. The engineer’s schedule normally sets lintel type and bearing lengths. Forming these openings belongs in the shell even when windows sit outside the price.
Structural steels appear where openings are wide or loads are concentrated. The engineer specifies them, and contracts differ on who supplies and who fits them. Clients should ask for supply only or supply and fit in writing.
Homebuilding notes that bespoke glazing cannot be measured until openings are formed. Lead times can reach three months or more, so window sizes should be confirmed before the walls rise.
Does a Shell Package Include Scaffolding and Site Access?
Scaffolding is sometimes included in a shell price and sometimes hired separately by the client. A quote should state who pays, how long the hire runs and which later trades can use it.
Access matters as much as scaffold. Deliveries of bricks, blocks and beams need a safe route and storage space, and heavier components may need lifting gear. Infill plots between existing homes in Birmingham can restrict all of this.
Waste and skips follow the same logic. A shell price may include rubble and offcut removal or leave it to the client. Written responsibility for each avoids disputes on site.

What Is Usually Not Included in a Basic Shell Package?
A basic masonry shell often excludes the items that make a building weathertight. Roofing may sit outside the price where another contractor handles it, and windows and external doors are commonly priced separately. Weathertight packages include them, so the quote wording matters.
Plumbing, electrical work and heating systems are usually excluded. A shell can still allow for pipe routes and service entry points. First fix, second fix and commissioning all sit with those trades.
Finishing work comes last. Plastering, joinery, kitchens and bathrooms, decorating, flooring finishes and landscaping usually fall outside a basic shell. Clients budgeting a whole project should cost each of these separately.
What Is the Difference Between a Shell-Only Build and a Turnkey Build?
A shell-only build ends at an agreed structural or weathertight stage. The owner then manages the remaining work, buying trade packages or paying for labour and materials directly, as Homebuilding describes.
According to Build It magazine, a turnkey build covers design, construction and fit-out to an agreed price and timescale. Some turnkey contracts still start from the slab upwards, so groundworks and landscaping can sit outside them.
The trade-off is coordination. Shell-only work gives owners control of the interior but makes them responsible for joining the packages together. Turnkey passes that coordination to a single provider.
How Does Shell Scope Differ for Self-Builds, Developers and Extensions?
Self-Builds and New Homes
A single new home often starts with a shell contract before fit-out begins. The self-builder usually coordinates what follows, so gaps in the shell scope become the owner’s problem to solve. Mortgage lenders can also look closely at how the build is delivered.
Developers and Multi-Unit Schemes
Developers usually need a scope schedule for each plot or house type. Repeated designs, phased handovers and warranty inspections make written boundaries more important than on a single house. Terraces and semi-detached pairs share walls, so setting-out and sequencing affect every unit.
Home Extensions
An extension shell usually covers foundations, a floor, new walls and any lintel or steel over the new opening. Tying new brickwork into the existing house, and matching the brick, belong in the scope. Older terraced and semi-detached homes in Birmingham, Solihull and Sutton Coldfield can need that detail checked on site.
Why Do Drawings, Engineer Specifications and Contract Scope Decide What Is Included?
Drawings show the floor type, wall build-up and every opening, so they set the physical scope. The structural engineer’s calculations then specify foundations, beams, steels and lintels. Building control checks that design, so builders price from approved information, not guesswork.
Material choices change scope as well. Facing brick, block grade, cavity insulation and floor system each alter what the shell covers. Approved Document A on structure gives guidance on building loads and on constructing foundations, walls, floors, roofs and chimneys.
The contract then fixes the boundary. Labour only, supply and fix, and full package prices each cover different work. Building control inspections, typically before foundations are concreted and before the ground floor is prepared, also follow the approved drawings.
What Should Clients Check Before Accepting a Shell Construction Quote?
A quote should state where work begins, at excavation or at slab level, and where it ends. The end point might be wall plate, roof structure or a weathertight building. The supply basis matters too, since labour only excludes bricks, blocks and cement.
A short checklist keeps comparisons fair:
- Drawings and the structural engineer’s specification, referenced by revision or date
- Foundation type and who removes spoil
- Ground floor system, plus any insulation or screed
- Brick, block and insulation specification, including the facing brick allowance
- Lintels, steels and padstones, as supply only or supply and fit
- Roof, windows and external doors, as included or excluded
- Scaffolding, lifting, skips and waste responsibility
- How variations and provisional sums are priced and agreed
Proof of insurance, a named point of contact and a written variation process also belong on that list. Totals only compare once the scope lines match. Pricing is a separate question that comes after that step.

The table below groups common shell items by how often they appear in a brick and block package. It is a question list, not a promise of what any one contractor includes.
What Should Birmingham Clients Remember About Shell Scope?
A new build shell is the structural stage of a house. In brick and block, it commonly means foundations where included, walls, floors, lintels and damp-proofing. Roofing, glazing, services and finishes may sit outside, and drawings, engineer specifications and contract wording decide where the line falls.

Frequently Asked Questions
Where does a new build shell usually stop and the fit-out begin?
A shell usually stops once the structure is complete. The exact point may be wall plate, roof structure or a weathertight stage. Fit-out then starts with first fix services, and contractors draw the line differently, so the quote should name that point clearly and in writing before work starts.
Does a brick and block shell include the roof, windows and external doors?
A masonry shell often stops before the roof covering, windows and external doors. A weathertight package includes them, and Homebuilding describes that stage as walls, roof, windows and doors in place. Check carefully which definition the quote uses before comparing any two prices.
Are foundations part of a new build shell or a separate groundworks package?
Foundations are part of the shell when the contract starts at ground level. Some packages start above the slab and leave groundworks to another contractor. The structural engineer designs the foundations, so the quote should clearly name who builds them and who removes the spoil.
What is the difference between a shell-only build and a turnkey new build home?
A shell-only build ends at an agreed structural or weathertight stage, and the owner arranges the fit-out. A turnkey build covers design, construction and fit-out to an agreed price and timescale. Shell-only gives control of the interior, while turnkey gives one point of contact.
Which parts of a house are not included in a basic shell package?
Basic shells commonly exclude plumbing, electrical work, heating, plastering, joinery, kitchens, bathrooms, decorating, flooring finishes and landscaping. Windows, external doors and roofing may also sit outside, depending on the contract. A written exclusions list prevents confusion later.
What should a Birmingham shell quote say about lintels, steels and scaffolding?
A Birmingham shell quote should list which lintels and structural steels are included, as supply only or supply and fit. It should also say who pays for scaffolding, how long the hire runs and who clears waste. Matching these lines to the engineer’s schedule helps avoid extras later.
