Comprehensive Building Solutions from Concept to Completion
At TMI Constructions, we offer a full suite of construction services tailored to meet the diverse needs of homeowners and property developers across London. From structural planning to interior fit-outs, we manage projects with precision and professionalism at every stage.
Our Core Services
We begin every project with a comprehensive pre-construction plan that considers site conditions, zoning restrictions, cost assessments, material availability, and realistic scheduling. Our planning process involves feasibility studies, budgeting, and value engineering to optimize design and cost efficiency. TMI ensures every construction milestone aligns with your goals, budget, and timelines before ground is ever broken.
Our engineering team oversees all structural and mechanical design aspects, including load-bearing assessments, MEP coordination (Mechanical, Electrical, Plumbing), and structural calculations. We collaborate with certified engineers to produce detailed technical drawings and conduct site-specific risk assessments, ensuring compliance with UK building regulations and industry standards.
We provide full construction project management, including resource scheduling, subcontractor coordination, quality control, site safety compliance, and progress reporting. TMI’s construction managers serve as the primary point of contact throughout the build, using critical path method (CPM) scheduling and cloud-based tools to maintain transparency and control from day one to handover.
TMI delivers custom home construction services for private clients, developers, and investors. We manage every aspect—from excavation and substructure to roofing and interior finishes—using top-grade materials and skilled tradespeople. All new homes are built to comply with NHBC standards, include Part L energy efficiency considerations, and can be tailored for smart home integration or luxury finishes.
Our renovation services go beyond cosmetics—we address underlying structural, electrical, and plumbing systems to deliver safe and beautiful interiors. Whether you're remodelling a single room or undergoing a full flat refurbishment, we handle wall removals, damp-proofing, underfloor heating, and bespoke joinery with minimal disruption. TMI is experienced in upgrading period homes to meet modern living standards while retaining architectural character.
We specialise in rear, side-return, and wraparound extensions that enhance functionality and property value. Every extension project includes detailed structural engineering calculations, steel frame installation, thermal insulation upgrades, and full compliance with local planning permissions and Party Wall agreements. Whether you're adding a kitchen diner or a multi-storey wing, we deliver seamless integration with your existing structure
Our team transforms attics into livable spaces through dormer, mansard, hip-to-gable, or Velux conversions. We ensure all conversions meet fire safety, head height clearance, and insulation standards. From staircase installation to skylights and ensuite bathrooms, our loft conversions are completed with full building regulation approval and maximum ROI in mind.
TMI Constructions delivers expertly crafted garage builds, garden rooms, and summer houses that extend your living and storage space with purpose and style. Whether you're looking for a secure vehicle space, a dedicated home office, gym, or entertainment retreat, we offer bespoke structures that integrate seamlessly with your property and landscape.
Our landscaping and gardening service goes beyond planting—we construct well-designed external spaces that enhance property value and usability. From garden regrading and drainage systems to hardscaping, paving, and turfing, we tailor each garden transformation to suit your lifestyle.
TMI provides comprehensive roofing services, delivering structural security, insulation, and visual appeal across residential projects. Whether installing a pitched roof for a new build, repairing storm damage, or re-roofing an existing structure,
At TMI Constructions, we offer professional cladding installation services that enhance both the thermal performance and aesthetic appeal of residential and commercial buildings. Cladding not only protects the building envelope from environmental elements but also contributes significantly to energy efficiency and visual identity.
TMI Constructions provides professional quantity surveying services to ensure your construction project remains cost-effective and financially viable from day one. Our in-house or partner quantity surveyors handle all aspects of cost planning, estimation, procurement, and financial reporting, ensuring transparency and control throughout every phase of the project.
Our building surveying service delivers expert evaluations of existing structures to identify defects, assess condition, and guide renovation, compliance, or acquisition strategies. TMI’s surveyors provide professional insights that help reduce risks, ensure building safety, and support long-term property performance.
