Frequently asked questions

An architect designs spaces, coordinates planning disciplines, prepares permit documents, manages costs and supervises execution. We balance:

• function and form
• legal and technical standards
• budget and architectural quality
• sustainability and future flexibility

Key factors are:

• trust and transparent communication
• a shared architectural vision and values
• relevant experience with your building type
• a clear contract and cost structure

We offer a free initial consultation – a chance to get to know each other and your project without obligation.

Design and permitting typically take 3–6 months, depending on the scope of the design and the permit review. Construction adds a further 12–18 months, depending on project size and external conditions.

From first design to handover, a project usually takes 18 to 24 months:

• 3–6 months: planning
• 2–4 months: permit review
• 12–15 months: construction

Individual factors such as weather or the availability of trades can affect the schedule.

Absolutely. Before renovating, we evaluate:

• structural stability, in coordination with structural engineers where needed
• compliance with current codes (e.g. energy, fire protection, sound insulation)
• the feasibility of spatial reorganisation
• energy and funding potential

We develop sustainable, phased renovation strategies and coordinate everyone involved.

It depends on the scope and type of renovation. For interior upgrades without structural work, phased occupation is often possible. We organise:

• construction in stages, room by room
• dust protection and temporary access
• minimisation of noise and downtime

Yes. Even small extensions affect the structure, fire protection and the legal framework. An architect ensures:

• compliance with building codes and structural requirements
• a coherent integration into the existing building
• optimisation of space, light and circulation
• avoidance of costly planning mistakes

Yes. Renovating listed buildings requires close cooperation with heritage conservation authorities. We offer:

• inventory analysis and documentation
• design of sensitive, reversible interventions
• coordination with the authorities
• integration of fire protection, accessibility and energy measures

Effective cost control begins in the early planning phases. We ensure:

• reliable cost estimates in every project phase
• transparent tendering and comparison of offers
• continuous cost tracking during construction
• a clear separation of construction and incidental costs

Professional tendering, contract design and site supervision minimise unforeseen costs.

Yes. We take over:

• preparation of tender documents
• solicitation and evaluation of offers
• comparative analysis of pricing
• advice during contract negotiations

This ensures transparency and quality before construction begins.

Yes. We perform construction supervision and represent the client's interests on site:

• monitoring time, cost and quality
• site meetings and protocols
• approval of invoices
• review of materials and execution
• documentation and handover

Yes. As the responsible architects, we manage:

• scheduling and construction sequences
• coordination between all trades
• on-site supervision to avoid clashes and delays
• communication between client, contractors and consultants

This role is essential for quality and schedule reliability.

An energy-efficient renovation significantly reduces a building's heat loss and energy demand:

• high-performance insulation of roof, façade and basement ceiling
• triple-glazed windows and airtight joinery
• modern, efficient heating such as heat pumps
• controlled ventilation with heat recovery
• minimisation of thermal bridges

KfW and BAFA are German federal funding programmes for energy-efficient building and renovation:

• KfW: low-interest loans and repayment grants for new construction and renovation
• BAFA: direct grants for individual measures such as heat pumps, ventilation systems or energy consulting

We advise on suitable programmes and support the application process together with qualified energy consultants.

Heat pumps are a key technology for decarbonising buildings. They are most efficient in well-insulated buildings with low-temperature heating. Options include:

• air-to-water heat pumps (lower investment)
• ground-source heat pumps (higher efficiency, higher investment)
• hybrid systems, e.g. in existing buildings

Sustainable design combines ecological responsibility with user comfort:

• compact, flexible floor plans
• renewable or recycled materials
• low energy demand through passive design
• adaptability to future use
• lifecycle thinking: deconstruction and reuse

In most cases, yes. Exceptions exist only for certain minor structures, depending on the state building code. Permission is required in particular for:

• new buildings
• extensions and conversions
• changes of use
• structural alterations

We handle the entire permit process, including coordination with the authorities and preparation of all necessary documentation.

A Bebauungsplan is a legally binding development plan. Among other things it defines:

• permitted use (e.g. residential, commercial)
• building lines and setbacks
• building heights and number of storeys
• plot coverage and floor-area ratio
• roof shapes, materials and design guidelines

Projects must conform to it or apply for specific exemptions.

Usually yes. A soil survey is essential to:

• determine the load-bearing capacity of the ground
• identify groundwater levels or contamination
• prevent settlement or foundation damage

It informs the foundation type and can significantly influence construction costs.

Yes. We plan in accordance with the relevant standards and the requirements of the state building code. Typical measures:

• step-free access
• sufficient door widths
• turning circles in bathrooms and kitchens
• future adaptability for ageing in place
