Living Area Extensions - Adding square meterage to expand your home where you need it most. Additional bedrooms, larger living spaces, home offices, or extended kitchens that open to outdoor areas - we design and build extensions that integrate seamlessly with your existing home.
Second Storey Additions - Maximising your section by building up when you can't build out. Perfect for Auckland's expensive land market, second storey additions create substantial extra space whilst keeping your garden. We handle the complex engineering, consent, and construction these projects require.

We create open plan layouts that suit today's lifestyle whilst maintaining structural integrity and managing consent requirements.

From dated 1960s homes to tired 1990s builds, we update everything including layouts, kitchens, bathrooms, flooring, lighting, and finishes. Your home emerges transformed inside whilst retaining its exterior character.

We blend respect for your home's existing character with contemporary design, delivering renovations that add genuine value and enhance your lifestyle whilst managing the complexities of working within existing buildings.
Why Choose Ash Building for Home Renovations
Experience with Auckland Homes - We've renovated hundreds of Auckland properties, from weatherboard villas in Ponsonby to brick and tile homes in East Auckland, fibrolite bungalows across the region to concrete block houses in South Auckland. This experience means we understand the construction methods used in different eras, potential issues hiding in walls or under floors, and practical solutions specific to each home type and age.
Respectful of Your Home and Family - Renovation means builders working in your personal space, often whilst you're living there. Our team maintains clean worksites with daily cleaning and rubbish removal, protects your belongings and surrounding areas with proper coverings and barriers, contains dust and debris to limit spread through your home, respects your privacy and household routines, and minimises disruption to your daily life. We understand renovation is stressful and work to make it as painless as possible.
Expert Problem Solvers - Renovations often reveal unexpected challenges. Outdated wiring that needs replacing, hidden water damage, structural timber that's deteriorated, or non-compliant previous work. Our experienced team identifies problems early where possible, provides practical and cost-effective solutions quickly, and keeps your project moving forward despite discoveries. This problem-solving ability comes from years of renovation experience.
Quality Craftsmanship - Your renovation is only as good as the workmanship behind it. Our licensed builders take pride in every detail, from perfectly aligned tiles to seamless joinery joins, crisp paint lines to flawless grouting. We use quality materials from trusted suppliers, proper construction methods that stand the test of time, and attention to finishing details that separate professional work from amateur efforts.
Transparent Communication - We keep you informed throughout your renovation without overwhelming you. You receive regular progress updates at agreed intervals, clear explanations of any variations or changes needed, direct access to your project manager for questions, and honest timelines without over-promising. No surprises, no guesswork, just professional service and clear communication.
Adding Real Value - Good renovations increase your property value and enhance daily living. We offer practical advice on improvements that deliver the best return on investment, whether for sale preparation or long-term enjoyment, design choices that suit your area's market, and realistic expectations about costs versus value added. Our goal is renovation that makes financial sense alongside improving your lifestyle.
Our Home Renovation and Extension Process
Step 1 Initial Consultation and Assessment
We meet at your property to understand your vision, discuss what you want to achieve, and assess existing conditions honestly. This consultation includes measuring spaces and reviewing current layouts, identifying potential challenges like services locations or structural constraints, exploring design options and possibilities, and discussing budget parameters and timeline expectations. We provide honest advice on feasibility and value, helping you understand what's realistic for your budget and property.
Step 2 Design Development and Planning
Working with your ideas and requirements, we develop detailed plans and specifications. For extensions, this includes architectural drawings showing new spaces, integration with existing structure, and external appearance. For renovations, we create comprehensive scope documents detailing all work, materials, fixtures, and finishes. We collaborate with designers or architects if needed, present options for materials and fixtures with samples where possible, and refine designs based on your feedback until everything's exactly right.
Step 3 Quotation and Contract
You receive a detailed, itemised quotation breaking down all costs transparently. We explain each element of pricing including what's included and what's not, discuss the realistic timeline from start to completion, clarify payment terms and milestone scheduling, and answer all your questions thoroughly. Once you're satisfied and ready to proceed, we formalise the agreement with a clear contract and schedule your project start date.
Step 4 Consent Management
If building consent is required for your renovation or extension, we prepare and submit all documentation to Auckland Council. This includes architectural plans and specifications, structural engineering where required, producer statements for specialised work, and any other required documentation. We manage the entire process including council liaison, addressing any conditions or requests for information, and keeping you informed throughout. Consent typically takes 20 to 30 working days for straightforward projects.
Step 5 Renovation Execution
Our skilled team begins work with careful site preparation and protection of your existing home. We establish dust barriers and protection zones, remove existing fixtures and fittings carefully, and commence demolition or preparation work. Throughout construction, we maintain clear communication with regular updates on progress, address any questions or concerns promptly, manage all trades including plumbers, electricians, tilers, painters, and joiners, and maintain site safety and cleanliness. Quality control happens at every stage ensuring work meets our standards.
Step 6 Completion and Handover
As work concludes, we conduct thorough quality checks on all workmanship, finishes, and functionality, complete final cleaning to leave your home pristine, arrange council inspections where required for code compliance certification, and walk you through your transformed space explaining any maintenance requirements. We ensure your complete satisfaction before final sign-off. Your beautifully renovated home is ready to enjoy, adding value and improving your daily living for years to come.
Understanding Renovation and Extension Costs
Renovation costs vary significantly based on scope and specification. Understanding key cost factors helps you plan effectively and make informed decisions:
Scope of Work - Single room updates like a kitchen or bathroom cost substantially less than whole-home renovations affecting multiple spaces. Extensions adding new rooms increase investment significantly. The scale of work directly impacts both materials and labour costs.
Age of Property - Older homes often require additional work beyond the visible renovation. Pre-1970s homes may need electrical upgrades to handle modern loads and meet current standards, plumbing improvements or replacements, insulation addition where missing, or structural repairs to deteriorated timber. These necessary improvements add to renovation investment but prevent future problems.
Finishes and Fixtures - Your selections significantly impact final cost. Kitchen appliances range from budget to premium with huge price differences. Bathroom fixtures, tapware, and fittings span enormous price ranges. Benchtop materials from laminate to engineered stone to natural stone. Tile selections from basic to designer. Flooring options varying widely in cost. Your choices here are often the biggest variable in renovation budgets.
Structural Changes - Keeping existing layouts costs less than major alterations. Removing walls requires engineering, consent, and structural work including beams or posts. Moving kitchens or bathrooms means relocating services with plumbing and electrical complexity. Creating new doorways or windows in exterior walls. Each structural change adds complexity and cost but may be essential for achieving the layout you need.
Services Upgrades - Many Auckland homes, particularly older ones, need services improvements during renovation. Electrical panels and wiring upgrades for safety and capacity. Plumbing improvements for better pressure and efficiency. Ventilation systems for moisture management, particularly in bathrooms and kitchens. Heating solutions for comfort. These upgrades add value and prevent future issues but increase initial investment.
Existing Conditions - Once walls open up, sometimes issues appear. Hidden water damage requiring repair. Asbestos in older homes needing professional removal. Structural timber deterioration. Non-compliant previous work. Inadequate foundations under walls. We work to identify these during initial assessment but some discoveries only happen during construction. Addressing them properly is essential for a quality renovation.
Consent Requirements - Building consent adds fees for applications, inspections, and any required engineering or architectural plans. Some renovations need producer statements from licensed professionals. Council fees vary based on project scope and any additional requirements for older homes or heritage areas.
We provide detailed, itemised quotations covering all labour, materials as specified, fixtures and fittings you've selected, all trades including plumbing, electrical, tiling, painting, and joinery, building consents and required documentation, rubbish removal and waste disposal, and site protection and daily cleaning. We explain what's included so you understand your investment completely. Our transparent approach means no hidden surprises, and we work within your budget whilst delivering the transformation you're after.
