An interior designer’s perspective.
Light, movement, storage and the connection to your living space. We consider your kitchen as part of your home, with a 3D proposal to review together.
I’m Sergio Castaño, your English-speaking kitchen designer on the Costa del Sol. We plan your kitchen through a private home consultation in Mijas, Fuengirola or Marbella, or work online if you live elsewhere. No showroom visit is needed.

01 — THE COSTAHAUS APPROACH
At COSTAHAUS, every project begins with a consultation dedicated to you. Time to listen, understand your home and discuss what you want from your new kitchen.
Light, movement, storage and the connection to your living space. We consider your kitchen as part of your home, with a 3D proposal to review together.
I explain the options and we review each choice. You continue working directly with me through design, material selection and coordination of ordering and fitting.
We decide where to invest according to your priorities. Your quote details cabinetry, worktops, appliances and services, with the scope agreed before confirmation.
02 — CHOOSE HOW WE START
I have chosen to work directly with my clients through private visits and online meetings. We study your kitchen in the context of your home and develop the project together, whether you are here or living abroad.
Request a private consultationPERSONAL KITCHEN DESIGN · ENGLISH AND SPANISH
Private appointments on the Costa del Sol and online kitchen planning throughout Spain.
Discuss your kitchen in the home it belongs to. Home consultations are available by appointment in Mijas, Fuengirola, Marbella and nearby areas. We confirm the visit scope and any charges before booking.
How home consultations work ↗Discuss layouts, furniture, worktops and appliances in English with Sergio. You have a direct contact to explain the design and the next steps.
Ask about a home consultation ↗If your home is in Spain but you live elsewhere, share your plans and photographs remotely. We agree who can provide access and verify measurements before supply or installation.

Online kitchen design packages ↗03 — FROM THE FIRST CHAT TO FITTING
Your first consultation, 3D planning, a proposal you understand, and coordination of ordering and fitting. Each step is agreed with you.
Tell me where your property is and what you would like to do. We arrange a private visit or an online meeting to discuss your ideas and priorities. You do not need every detail decided.
We study your plans and photos, or I visit to measure. We develop the layout in 3D and review the proposals together, remotely or in person.
We define cabinetry, finishes, worktops and appliances. You receive a written quote explaining what is included, expected timelines and conditions.
After approval and measurement checks, I coordinate ordering, delivery and installation with specialist kitchen fitting companies. I remain your point of contact after delivery, including for any issues and aftersales support.
Starting online does not replace final checks at the property. Measurements are verified before ordering; products, timelines and services are defined in the proposal.
04 — IDEAS FOR YOUR KITCHEN
Kitchen moods and palettes to discover what you like. We combine the ideas and adapt them to your space.
Wood, stone and sand tones. Textures that bring warmth and an island that invites you to stay.

Palettes are a starting point. We confirm colours and finishes with samples before you choose.

05 — THE PERSON BEHIND THE PROJECT
Over five years designing kitchens on the Costa del Sol.
I studied interior design and architecture in Granada, completed an interior design degree in Birmingham and undertook an internship in Padova, Italy.
Before COSTAHAUS, I managed a kitchen department and the complete client journey: samples and materials, design, home measurement visits, quotes, sales, ordering and installation coordination with several fitting companies. I also handled issues, aftersales and follow-up, and designed the kitchen showroom. I have also attended Nobilia’s new product showcases on several occasions.
With COSTAHAUS, I bring that education and practical kitchen experience together to work directly with you. Private consultations, at your property or remotely, and personal attention throughout design and project coordination.

PLANNING YOUR KITCHEN
You can start planning your kitchen without being in Spain. The key is sharing the right information and agreeing which decisions can be made online and which require someone at the property.
Read the guideBEFORE WE BEGIN
I have chosen to work directly with my clients, at their property or remotely. Each consultation is dedicated to understanding your home, listening to your priorities and reviewing the project with you. Personal contact continues through design, decisions and coordination of ordering and fitting.
COSTAHAUS operates without its own showroom. We work through private visits to your property or online meetings, with direct contact with me. We agree how you will see samples and check finishes before confirming your kitchen.
Yes. Send me plans, photos and references. We can develop and review the design by email, WhatsApp or video call, in English or Spanish. For a Costa del Sol kitchen, we agree property access, measurement checks and the stages that require someone there.
We can plan the project with cabinetry, appliances, worktops and installation coordination. Your proposal will detail exactly what is included and under which terms.
Installation is carried out by companies dedicated exclusively to kitchen fitting, with over 20 years of experience on the Costa del Sol. I coordinate the installation with them and remain your point of contact throughout the project. The included work and schedule are set out in your proposal.
You contact me. I continue looking after your project after fitting: I receive your enquiry, coordinate it with Nobilia, the worktop company or the appliance manufacturer as appropriate, and keep you informed. If the issue concerns installation contracted through COSTAHAUS, I also coordinate the review with the fitting company.
New products sold to you by COSTAHAUS as a consumer in Spain have a three-year statutory guarantee from delivery for lack of conformity. I provide the guarantee terms for the Nobilia cabinetry, worktops and appliances. Any additional commercial warranty complements your statutory rights without reducing them. I coordinate aftersales enquiries for the products we supply.
It depends on the dimensions, layout, materials, appliances and installation. We start with your budget and define a specific proposal. The design scope and any costs are agreed with you before proceeding.
