Architecture and feasibility, answered plainly.

Feasibility, concept design and the drawings before planning is submitted.

Architecture and feasibilityStraight answers

What people ask us about architecture and feasibility.

What does a feasibility study tell me?

It tests whether your brief, property, likely approvals, budget and programme fit together.

We compare options and identify any missing surveys, before developing your preferred scheme.

Next Agree the options to test and the decision the study needs to support.

Why do I need a measured survey?

Reliable dimensions and levels give our design team a shared starting point.

Sales plans are useful background. Do not assume they are accurate enough for coordinated design or fabrication.

Next Confirm the survey scope, including levels and relevant external features.

What other surveys might be needed?

The property and proposed work decide what we need. This can mean structural, drainage, asbestos, ground, utilities, damp or heritage surveys.

Not every survey is needed on every project.

Next Ask us for a survey schedule explaining the purpose of each investigation.

What is the difference between planning drawings and construction drawings?

Planning drawings explain the proposed development, for assessment.

Construction information needs more coordination and detail, covering structure, services, materials and junctions. This is what lets the work be priced and built.

Next Ask us who develops the technical package after planning.

Can the internal layout be redesigned without extending?

Yes. Often the most useful feasibility work tests circulation, storage, daylight and room relationships. This is within the existing envelope.

Structural and service constraints still need investigating.

Next Ask us to compare a layout-only option with any proposed extension.

When should the structural engineer and MEP designer join?

We bring them in early to test openings, plant space and floor depths. We also test service routes, before the architecture is fixed.

Late coordination can force changes to ceilings, rooms and budgets.

Next Ask us to identify the technical decisions that could change the layout.

Can I see the design in 3D before agreeing it?

Ask us which visual tools are included in your appointment.

Models or visualisations help explain volume and materials. They do not replace dimensions, samples or technical information.

Next Agree which rooms or junctions need additional visual explanation.

How many design revisions are included?

Your appointment sets out the design stages and included review rounds.

Major brief changes after approval can mean extra work and a longer programme.

Next Consolidate household feedback before each design review.

Can NU design a new house or replacement dwelling?

Yes, we design new houses and replacement dwellings.

Feasibility work compares the existing building, proposed accommodation, site constraints and delivery scope. We do this before any construction commitment.

Next Ask us to confirm the new-build service and appointment.

Can I combine adjoining properties or convert a house into flats?

These proposals need a planning, ownership, structural and servicing review specific to your property.

The effect on neighbours, escape routes and building control arrangements can be substantial.

Next Share title information, existing uses and the intended final accommodation.

How do design approvals affect the programme?

Approving a stage sets the basis for the next package.

Changes after technical coordination or ordering can mean redesign, wasted work and replacement purchases.

Next Keep a design approval schedule linked to procurement dates.

How is design quality maintained when costs are reviewed?

We identify what makes the scheme work: proportions, light, circulation and key materials.

We test any savings against those priorities. We avoid unrelated substitutions made room by room.

Next Agree a short list of design priorities before value reviews.

How can sustainability be included without compromising the design?

We set priorities for useful space, retained fabric, durable materials, energy demand and maintainability.

We compare alternatives over the life of the home. We do not rely on an unsupported green label.

Next Ask us to define measurable priorities and how options are assessed.
