Building six flats is not the same as building one house six times. A multi-unit development introduces shared services, communal areas, repeated specifications, tighter sequencing and a greater need for consistent quality control.
For investors and small developers, decisions made before construction begins can directly affect cost, programme, quality and commercial viability. A successful scheme needs more than planning approval and a headline build price. It needs coordinated technical information, realistic allowances, early procurement decisions and a contractor who understands how every part of the development connects.
TNK Construction Ltd supports London investors through new builds, multi-unit construction, fit-outs, project management and carpentry. The company has 17 years of experience and is led by Tim Gjana, who has more than 20 years of construction industry experience.
Why Six Flats Need a Different Strategy
A six-flat scheme should be managed as one coordinated development, not as six separate homes. Decisions affecting one unit can influence the structure, drainage, ventilation, shared access, services and finishes across the building.
Repetition can create efficiency, but only when layouts and specifications are agreed early. If a bathroom detail, service route or door opening is wrong, the same issue may be repeated across several flats.
Investors should also define the intended market. A long-term rental scheme may need a different specification from a premium build-to-sell development. The finishes should be durable and proportionate to the expected value of the completed units.
Start With Development Viability
The construction quotation is only one part of a development appraisal. Investors should also consider professional fees, surveys, planning conditions, utility connections, finance and contingency.
A low initial quotation does not automatically offer better value. If drawings are incomplete or the scope contains significant exclusions, costs may return later through variations, delays or design changes.
A dependable assessment should be based on coordinated architectural and structural drawings, service requirements, drainage information, kitchen and bathroom layouts, finish schedules, carpentry details and external works.
It should also make clear which items are supplied by the client and which are included within the contractor’s scope.
Planning Approval Is Not Construction Readiness
Planning drawings show the approved design, but they may not contain all the information required to build it.
Before breaking ground, the project team should understand how the structure, services, drainage, ventilation, windows, doors, floor build-ups and communal areas will work together.
Buildability should also be reviewed. A detail may look straightforward on paper but be difficult to install repeatedly across six units. Early coordination can reduce clashes between trades and unnecessary pressure on the construction programme.
Plan the Specification and Programme Early
Standardising suitable kitchens, bathrooms, doors, flooring and carpentry details can simplify procurement and improve quality control. Larger or premium units may still justify selected upgrades.
The main specifications should be agreed early. Kitchens, sanitaryware, tiles, doors and bespoke joinery can have long lead times. Delayed selections may interrupt first-fix, second-fix and finishing works.
The construction programme must follow the practical order of work. Structure, roofing, windows, first-fix services, internal linings, plastering, carpentry, kitchens, bathrooms, flooring and decoration all depend on earlier stages being completed correctly.
One delayed package can affect several flats. Completing a benchmark flat first can help the investor and contractor approve the expected finish before repeating it throughout the development.
Project Management Protects the Investment
Project management connects drawings, trades, procurement, cost decisions and quality checks.
Clear responsibility is essential. The investor should know who can approve changes. The contractor should know which information is current. Suppliers should receive confirmed specifications rather than provisional selections.
Variations should explain what has changed, why it is required, which units are affected and whether the programme will change.
“Building several flats successfully is about controlling the interfaces between every part of the project. The structure, services, fit-outs, carpentry and finishes all need to follow one coordinated plan.”

Fit-Outs, Carpentry and Quality Control
The structural build creates the development, but the fit-out shapes how buyers and tenants experience it.
Kitchen layouts, bathroom details, flooring transitions, lighting positions, internal doors, skirting and storage should be coordinated before installation.
Carpentry should also be designed into the scheme. Door openings, staircases, service cupboards, wardrobes and communal joinery depend on accurate dimensions and confirmed floor levels.
Quality checks should take place throughout construction, not only during final snagging. Approving the first bathroom, door set or flooring transition creates a benchmark that can be repeated across the remaining units.
TNK Construction completed a six-flat project in Richmond, demonstrating the importance of coordinated sequencing and consistent delivery on a larger residential scheme.
Site Logistics Matter in London
London sites often have restricted access, limited storage and neighbouring properties close to the work.
Deliveries, waste removal, temporary services, security and material storage should therefore be planned around the construction programme.
Products should not arrive before safe storage is available. Completed kitchens, flooring, carpentry and decoration must also be protected while work continues elsewhere.
Poor site logistics can interrupt trade sequencing, increase labour requirements and create avoidable damage to completed work.
Final Thoughts: Next Steps for Investors
Before construction begins, investors should confirm the development strategy, planning position, technical information, specification, budget, procurement schedule and decision-making process.
TNK Construction can review the available drawings, site constraints and proposed scope before discussing the practical requirements of delivering the project.
The objective is not simply to complete six flats. It is to deliver one finished development that meets the investor’s commercial, practical and quality expectations.

Frequently Asked Questions
What Should Investors Plan Before Building Six Flats?
Investors should plan the project scope, technical design, building services, specification, procurement, site logistics, construction programme, contingency, quality control and handover process.
How Is Building Several Flats Different From Building One House?
A multi-unit project includes repeated kitchens, bathrooms and services, together with shared entrances, staircases, corridors and communal areas. Decisions affecting one detail may need to be coordinated across every unit.
Can TNK Construction Manage Multi-Unit Projects in London?
TNK Construction supports new builds and multi-unit developments across London through construction delivery, project management, internal fit-outs and carpentry.
How Can Investors Reduce Construction Variations?
Investors can reduce avoidable variations through a clear scope, coordinated drawings, early material selections, realistic allowances and a controlled approval process.
