Finishes, Interior & Exterior
When a build reaches the finishing stage, detail becomes everything. ARN Projects, led by Arron Dewhurst, treats luxury custom home finishes as the visible signature of craftsmanship, where every floorboard, tile line, paint edge and cladding joint reflects the quality beneath.
This article sets the standard, offering practical guidance, clear specification and a reliable process for delivering durable, beautiful interiors and weather-tight, low-maintenance exteriors.
Flooring That Performs and Lasts
Flooring shapes first impressions and everyday comfort, so the specification must balance appearance, performance and budget. ARN Projects compares solid and engineered timber, LVT and SPC, porcelain, and natural stone based on wear layers, slip resistance, impact sound and maintenance requirements.
In kitchens and family rooms, robust engineered timber or high-quality LVT over acoustic underlay handles heavy footfall while reducing sound transmission in line with Part E. Bathrooms call for porcelain tiles with a suitable slip rating and epoxy grout for improved stain resistance. For underfloor heating, stable formats such as engineered timber or porcelain with decoupling membranes help prevent movement cracks and maintain thermal responsiveness.
Substrate preparation is essential. Moisture testing, levelling compounds, acoustic layers and primers all form part of the method statement so the finished floor sits flat, feels solid and ages well. Door threshold details, skirting interfaces and transitions to carpets are agreed during pre-start, so there are no awkward trims or trip hazards later. The result is a cohesive floor plan that feels intentionally designed because it is.
Plaster, Skim and Perfect Edges
Smooth walls do not happen by accident. ARN Projects sequences boarding, taping and jointing, skimming and drying times so the plaster finish cures properly before decoration begins. Corners are set true with metal or PVC beads, reveals are kept plumb, and control joints are introduced in larger spaces to reduce the risk of hairline cracking.
Where breathability matters, such as in heritage or stone properties, lime plaster or mineral-based systems are specified to manage moisture without trapping it in the wall build-up.
Ceiling lines, bulkheads and shadow gaps are modelled early. The team coordinates plasterboard thicknesses around pocket doors, coving, MVHR terminals and downlights to avoid last-minute compromises. Quality is judged in daylight and under raking light, not just under temporary site lamps. If it looks flawless then, it will keep looking flawless.
Paint That Protects as Well as Polishes
Paint is both colour and protection. ARN Projects recommends low-VOC emulsions for healthier indoor air quality, durable acrylic eggshell for high-traffic areas, and specialist scrubbable finishes for hallways and utility rooms. In bathrooms and kitchens, moisture-tolerant systems with stain blockers help prevent ghosting and tannin bleed. For masonry and external joinery, breathable mineral or microporous paints allow substrates to release moisture, extending the life of render and timber.
Preparation is what makes the difference. Substrates are sanded, dust-free and primed, plaster receives a mist coat, knots are sealed, and caulk lines are kept crisp rather than smeared. Colour placement is handled with intent, with feature walls aligned to natural light, ceilings lifted with the right sheen, and woodwork contrasted to create depth. Sample boards are produced on site so the client can choose under real lighting conditions rather than guesswork.
Tiling with Technical Precision
Tiles need to be beautiful, but they also need to be correctly bedded, aligned and detailed. ARN Projects uses decoupling membranes over heated screeds, sets out from focal points, and keeps grout joints consistent with levelling clips where appropriate.
Falls to wet room drains are formed within the substrate, not improvised in the adhesive. Movement joints are introduced at perimeters and thresholds in line with BS standards, helping protect large-format porcelain from stress.
The system matters as much as the tile itself. Primers must be compatible with the substrate, adhesives must be flexible, shower zones need waterproof tanking, and grout should be epoxy or polymer-modified where required.
Niche shelves, mitred external corners and tile-to-glass transitions are designed before the first tile is cut. The outcome is a bathroom or kitchen that looks crafted, not pieced together.
Joinery That Defines the Room
Joinery is one of the clearest touchpoints of quality. Doorsets are hung to tight tolerances, gaps are even, ironmongery lines up, and latches close with a quiet, engineered feel.
ARN Projects provides bespoke cabinetry, wardrobes, staircases, skirting and architraves that elevate spaces while concealing services neatly. Shadow gaps, scribed skirtings and clean returns avoid filler-heavy shortcuts. Where fire-rated doors are specified, whether FD30 or FD60, compliance is built in through intumescent strips, compatible ironmongery, correct closers and the right certification.
Coordination with MEP is rigorous. Access panels are integrated discreetly, boxing-in is minimised through early routing, and ventilation grilles are selected to suit the palette rather than stand out.
Finishes such as oils, lacquers and paints are chosen for durability and feel as well as appearance. The joinery package bridges the shell and the way the home is actually lived in, so it deserves close attention.
Facades That Weather Well
External finishes shape kerb appeal and long-term building performance. ARN Projects works with brick and stone, through-colour render, timber and composite cladding, fibre-cement and metal rainscreen systems. Each option is assessed for exposure, maintenance needs, fire performance, warranties and cost in use.
The details are what keep facades sharp for decades, including properly installed cavity trays and weeps, aligned bed and perp joints, consistent pointing, and stainless steel fixings that will not bleed.
Through-colour silicone renders can resist staining and algae when combined with the correct basecoats and mesh reinforcement. Brick slips can achieve a masonry look on lightweight structures, provided certified systems, mechanical fixings and drainage planes are used.
With timber, species choice, treatment class and back-ventilation are critical, while composite alternatives offer greater stability where regular maintenance is not desired. The guiding principle is consistent: attractive exteriors built on breathable layers, controlled drainage and dependable fire barriers.
Cladding as a System, Not a Surface
Cladding is not just decorative. It is a rainscreen system. ARN Projects designs from the breather membrane outwards, including fire-stopping at floor zones, ventilated cavities with insect mesh, UV-stable membranes where joints remain open, and fixings specified for durability.
Panel layouts are set to window modules to avoid thin slivers, corners are resolved with matching trims or folded returns, and soffit, fascia and coping details are drawn before procurement so suppliers can support both the intended appearance and the warranty.
Where planning constraints or coastal exposure influence material choice, the team guides clients through fibre-cement, aluminium, high-pressure laminate and treated timber, balancing embodied carbon, maintenance requirements and lifecycle cost. Every interface, from cladding to render, brick or roofline, is resolved so water sheds cleanly and the building envelope remains airtight.
Sequencing, Samples and Snag Control
Flawless finishes come from methodical sequencing. ARN Projects sets a finishes programme that respects drying times for screeds and plaster, first and second fix MEP works, including integrated technology within finished living spaces and the cleaning stages required before final coats. Sample boards, on-site mock-ups and manufacturer sign-off remove uncertainty.
O&M manuals, care guides and warranty registrations are prepared before handover so the client understands how to maintain every surface properly.
Snagging is proactive rather than reactive. Raking light inspections identify imperfections, silicone lines are checked at eye level, floor protection stays in place until the final trade has left, and the final clean reveals the true quality of the work. This is where trust is earned, by handing over a home that looks immaculate on day one and stays that way.
Sustainability Without Sacrifice
Sustainable finishes no longer require compromise. Low-VOC paints, FSC-certified timber, recycled-content tiles and durable cladding with long service intervals can reduce environmental impact as well as maintenance costs.
Breathable mineral systems help regulate humidity and support healthier indoor air quality. With thoughtful specification, ARN Projects delivers modern, energy-efficient and healthy homes where the finishes support wider performance goals such as acoustic comfort, thermal efficiency and airtightness rather than working against them.
FAQ: Finishes, Interior & Exterior
How do you prevent cracks in plaster and tile after completion?
By sequencing drying times correctly, using control joints, installing decoupling membranes over heated screeds, and specifying flexible adhesives and grouts. Movement is managed, not ignored.
What paint systems do you recommend for busy family homes?
Low-VOC, scrubbable emulsions for walls and durable acrylic or water-borne enamels for woodwork. In kitchens and bathrooms, moisture-tolerant systems with stain blockers help keep surfaces clean and mould-resistant.
Is timber cladding high maintenance in the UK climate?
It depends on the species, treatment and detailing. With proper ventilation, drip details and microporous finishes, or by choosing composite alternatives, maintenance intervals can be long and predictable.
Can you integrate underfloor heating with timber floors?
Yes. Engineered boards with stable cores work well. ARN Projects pairs them with the correct underlays and temperature ramp-up protocols to avoid excessive movement.
How do you ensure exterior cladding is safe and compliant?
Certified rainscreen systems are specified with appropriate fire performance, continuous cavity fire-stops are installed, and manufacturer fixing patterns are followed. Warranties and test data are included in the handover pack.
