New Build
Construction
Residential and commercial new-build construction from TCM’s Borehamwood base, with project roles, specialist input and coverage confirmed for the individual site.
New Build Services
New-build scope varies by site and project. TCM can undertake the agreed construction work and coordinate contractors or professional disciplines where that responsibility is included in the written scope.
Detached New Builds
Custom-designed detached houses on individual plots, built to your specification from foundations to final finishes.
Semi-Detached & Terraced
New semi-detached and terraced houses, including infill plots and gap-site developments in urban areas.
Self-Build Projects
Construction work for self-build projects can be discussed from the available design information, agreed construction scope and specialist responsibilities.
Bungalows & Annexes
Single-storey new builds, bungalows, and self-contained annexes for multi-generational living or rental income.
Garden Plot Developments
New-build construction on garden or subdivided plots where planning, access, utilities, design and construction responsibilities are confirmed for the actual site.
Commercial New Builds
New commercial buildings, warehouses, and mixed-use developments for business and investment clients.
Our 7-Stage New Build Process
The project stages depend on the site, appointments and procurement route. The sequence below is a planning framework rather than a universal TCM promise to manage every stage.
Site Assessment & Feasibility
Review the plot, available information, constraints and the professional inputs needed before design, budget and programme assumptions are relied on.
Planning Route
Where included in the scope, coordinate architects or planning professionals and establish who prepares, submits and manages the relevant application and conditions.
Design & Specification
Develop the project design, structural information, specification and applicable building-control route through the responsible professional appointments.
Quotation & Procurement
Price the defined construction scope, stating inclusions, exclusions, allowances, VAT basis and unresolved items.
Groundworks & Structure
Carry out the agreed construction work to the approved project information and specialist requirements.
Services & Finishes
Coordinate the specified building services, internal finishes and specialist interfaces according to the agreed project scope.
Completion & Handover
Snagging, completion records, approvals, manufacturer information and any warranties are provided by the responsible parties where applicable to the agreed scope.
New Build Cost Scope
The current register does not approve a universal TCM new-build £/m² range. Compare project-specific quotations only after the design basis, site conditions, professional/statutory costs, VAT treatment, allowances and exclusions are clear.
| Specification | Typical Cost | Notes |
|---|---|---|
| Plot and site conditions | Project-specific | Access, demolition, ground conditions, utilities and enabling works |
| Structure and envelope | Project-specific | Design, structural system, roof, windows and external fabric |
| Building services | Project-specific | Mechanical, electrical, drainage and utility scope |
| Internal specification | Project-specific | Kitchens, bathrooms, finishes, joinery and client selections |
| Professional and statutory scope | Confirm separately | Design, surveys, planning, building control and other project-specific fees |
| VAT and exclusions | Confirm in quotation | Compare quotations only after tax basis and exclusions are clear |
Costs are project-specific. Confirm the design/scope basis, professional and statutory costs, VAT treatment, allowances and exclusions in the written quotation.
New-Build Cases Require Verified Source Evidence
The current Experience Inputs Register contains no approved TCM new-build case, testimonial, programme outcome or project-size evidence for this page. Any future project example should identify the actual site context, TCM role, decision or outcome, supporting record and permission to publish before it is presented as first-party evidence.

New Build FAQs
Planning responsibilities are project-specific. Where coordination forms part of TCM's scope, TCM can work with the appointed architect or planning professional, but the responsible applicant, professional and application route must be stated for the project and approval is not guaranteed.
There is no reliable universal programme without a defined design and site. Planning conditions, surveys, groundworks, structure, utilities, procurement, weather, specification and changes can all affect duration. The programme should be prepared from the actual scope.
New-build projects normally require structural design information appropriate to the proposed building. The responsible structural professional, deliverables, fee responsibility and building-control inspections depend on the project and appointment.
TCM can undertake new-build construction on a suitable garden or subdivided plot where the required planning, design, utility, access and construction responsibilities are confirmed. Planning, design, utilities, access, groundworks and specialist responsibilities depend on the individual site. Confirm the planning route rather than assuming ordinary householder permitted-development rights apply.
Warranty requirements and providers depend on the project, lender/developer requirements and written terms. Do not assume a particular 10-year scheme or provider is included unless it is identified in the project documents.
TCM is based in Borehamwood, Hertfordshire. Project coverage is confirmed for the individual address, scope and specialist requirements rather than stated as universal coverage of every London or Hertfordshire area.
New-Build Enquiries
Contact TCM to discuss your project. Assessment, professional input and the scope needed before a project-specific quotation are confirmed for the individual project.
A new build creates a new building on an agreed site. The project can involve planning, surveys, design, structural and services engineering, building control, utilities, groundworks, construction and handover. TCM can undertake the building work and coordinate contractors or professional disciplines where this forms part of the agreed scope; professional and statutory responsibilities remain project-specific.
A new-build enquiry should start with the site, intended use, available design information, access, utilities, planning context and the responsibilities already assigned to designers or specialists. TCM can undertake the agreed construction scope directly and coordinate contractors or professional disciplines where that responsibility is included for the individual project.
What You Need to Know
Project Coordination, Groundworks to Completion
TCM can deliver building work directly and coordinate appropriate contractors, specialists and professional disciplines where required. The exact design, statutory, specialist and project-management responsibilities are set out for the individual project.
Planning and Building Regulations
A new-build project needs the appropriate planning and building-control routes for the site and proposal. TCM can coordinate with architects, planning consultants, structural professionals and other specialists where this forms part of the agreed scope; approval outcomes are not guaranteed.
Project-Specific Warranty Arrangements
Warranty and aftercare requirements depend on the project, lender/developer requirements, selected provider and written project terms. This page does not claim that every TCM new build includes NHBC or another particular warranty scheme.
Residential & Commercial New Builds
TCM offers residential and commercial new-build construction. The design, specification, procurement route, professional appointments and construction scope are established for the individual project rather than treated as one standard package.
Everything Else You Should Know
Understanding Your New Build Costs
New-build cost depends on the plot, site conditions, size, structure, services, specification, professional scope, statutory requirements, access and exclusions. TCM can price an agreed construction scope once sufficient project information is available; no generic TCM £/m² benchmark is approved in the current evidence register.
Navigating Planning Permission and Building Regulations
A new dwelling normally requires a specific planning route and must meet the applicable Building Regulations. The responsible applicant, designers, building-control body and other dutyholders depend on the project. TCM can coordinate relevant interfaces where agreed, but does not promise an approval outcome.
New Build vs. Renovation: Which is Right for You?
The choice depends on the existing property, site potential, desired layout, planning position, structural constraints, budget and disruption. Compare the actual scopes rather than assuming renovation is automatically quicker or a new build automatically better value.
Common New Build Planning Risks
Budget assumptions, incomplete surveys, unresolved design responsibility, planning conditions, utilities, ground conditions and specification changes can all affect a new-build project. The project team should resolve the relevant information progressively rather than relying on generic programme or cost assumptions.
